Race Glaze Water Filter 25 Litre
In Stock
Usually ships in 24 Hours

Our Price: £299.99 (inc VAT)
Larger 25 Litre resin capacity 0 PPM in-line water filter, ideal for professionals and serious detailers with collections of cars. Works in exactly the same way as the 7 litre version, should typically produce approx. 1400 litres of pure filtered water which will leave NO water spots on your vehicle, no matter what colour it is or how hot it is when washing. This prevents adding drying marks or swirls, water spots etc. And saves time. Water output figures will vary with your local water hardness, most people will achieve better results - this is based on medium hard Hertfordshire water. Complete with 25 Litre of pure first grade ion exchange resin producing drinking water quality filtered water. It is illustrated next to the smaller, standard 7 Litre filter, and stands approx. 1 metre tall. It will need securing to a wall to prevent it falling over, though our Water Filter brackets do not fit this unit. We recommend that a final rinse is performed at half mains pressure, just sufficient to create a wave of water over the vehicle, and should be able to be completed in around 45 seconds for a standard family car, little over a minute for a 4x4. This is based on our own usage over the last 4 years. Our resin vessels are made in Europe (many are not) and comprise a PE inner shell and wound fibreglass outer. These are high quality, strong units with best quality fittings and top grade resin. NOTE ON SHIPPING OUTSIDE MAINLAND UK These are heavy items and our low standard carriage rate is designed to keep costs down for customers of our standard size car care products. Shipping for these filters outside mainland England, Scotland and Wales is simply too much for us to absorb and unfortunately has to passed onto customers. Shipping to Northern Ireland for instance, for a filter alone is £25 in total. Please contact us if you live outside mainland UK. WARRANTY The product is warranted free of manufacturing defects for 12 months, but the resin media is a consumable and not covered. If the vessel is dropped or falls, warranty on the cap and body is void.

Race Glaze Water Filter 14 Litre
In Stock
Usually ships in 24 Hours

Our Price: £189.99 (inc VAT)
New, taller and 30% more efficient water filter to make your car washing easier - no white water spots and no need to dry the car. Saves time and reduces marring and drying risks. This new 14L filter produces around 1,100 litres of pure zero parts per million filtered rinse water before the resin needs replacement (buy 2 x 7L refill bags). Our smaller, 7L vessel produces 415L, so this new, larger unit is significantly more economical. In comparison to other, 'window cleaner suppliers' units, the combination of our resin and taller filter makes this more economical. See our detailed explanation why below. Note that as it is tall and slightly top heavy, you will need to secure it upright - we supply wall brackets which will achieve this. It is illustrated with our 7 Litre filter. The use of “mixed resin bed” water filters to remove all of the dissolved impurities has long been established in industries such as Pharmaceuticals, electronics and metal surface treatment. More recently, large scale car wash systems (such as tunnel washes), window cleaners and horticulturalists have also been using the products to produce water free from impurities. Note: filled with 14L of resin and ready to use. For the car wash and window cleaning industry, the advantages are that using water which contains no dissolved impurities allows the user to leave the car or window wet, to dry naturally and with no trace of water marks. The use of these filters is not simply a case of just connecting up a unit and running water through it though. The size and shape of the unit has a big impact on the maximum flow rate of the water through the unit, the volume of water that can be treated before the resin needs changing and also the quality of the water produced. The performance of a water filter comes down to contact time between the water and the mixed bed resin within the unit. The longer the contact time, the better the quality of the water will be, as the resin has longer to remove the dissolved ions (or impurities). The best way to achieve long contact time is to have a good amount of resin in relation to the flow rate of the water. This is represented by what is known as the 40 bed volumes per hour rule. That is the bed volume of resin in the unit multiplied by 40 which gives the optimum flow rate of water for that sized unit per hour. So a unit with 6 litres of resin in should (theoretically) be able to treat up to 240Lts per hour. In real terms this rule is rarely adhered to however, but does give a good guideline to the effectiveness if individual units. Unfortunately the story doesn’t end there as the “aspect ratio” of the filter also needs to be taken into account. This is basically the height of the filter divided by the diameter. The bigger the aspect ratio (i.e. the taller and thinner the unit) the better the performance will be. This is because the water has a greater depth of resin to pass through and therefore the resin has a greater chance of removing all of the impurities. A narrower diameter filter will also ensure that the water is distributed across the whole cross sectional area of the filter, thereby using all the resin bed to its maximum capacity. The standard Race Glaze 7L filter is a 6” diameter by 18” high vessel, which has an aspect ratio of 3. The vast majority of window cleaning filter products are based either on 8”diameter by 17” high vessels which only have an aspect ratio of 2.1 or a 7” by 13” vessels which only has an aspect ratio of 1.9. As such these units can suffer with the external edges of the resin not being fully utilised, and therefore giving lower capacity than the volume of resin would suggest. In the window cleaning industry this isn’t so much of a problem as the filters are generally used as the final stage of a multiple stage purification process. As such the water is already quite pure before it gets to these filters, so any shortfall in efficiency isn’t really noticed as they have such a low mineral load anyway. With mains water however the load on the resin is much higher, with the mineral content of the water often being tens of or even a hundred of times higher than the water from the window cleaning purification process. The new Race Glaze 14L filter is a 6” diameter by 35” high vessel having an aspect ratio of 5.8, far in excess of anything else available on the market. Coupled with a large resin capacity of 14 litres this filter now has unrivalled capacity for those who like to use a lot of water when rinsing their car. The tested capacity figures also bear this theory out. We filled 3 separate vessels with the same mixed bed resin (Purolite MB400) and tested the overall capacity at the same standard flow rate (6 litres per minute) using Harpenden towns mains water at a TDS of 420. The volume of water produced before the quality reached 10ppm (still good enough to no give spots, but a sign that the resin bed is beginning to fail from its initial 0ppm reading) were as follows:- • Race Glaze 6” by 18” 7L filter gave 415 litres of water from 7 litres of resin. • Window Cleaning type 8” by 17” filter gave 480 litres of water from 10 litres of resin. • Race Glaze 6” by 35” 14L filter gave 1105 litres of water from 14 litres of resin. You can see from these figures that by simply using a taller thinner filter you significantly increase the capacity of the unit from 59 litres of water per litre of resin with the 6x18 to 79 litres of water per litre of resin with the 6x35. So what’s the downside then? The reason the window cleaning industry tend to use 8x17 vessels is that they tend to be a bit dumpier and if stored in a moving van (as they generally are) they will be more stable than a taller thinner unit. Clearly a 6” diameter by 35” high filter is going to be top heavy and more likely to fall over, so needs to be secured, but if sited in your garage then securing the filter shouldn’t be a problem. We do offer a heavy duty wall bracket which will do the job. The only other downside is that the old trick of “backwashing” the filter probably won’t give you extra capacity as the filter has used all of its resin bed up by being efficient in the first place. The backwashing process (where the inlet and outlet connections are swapped over and water passed upwards through the filter) moves the resin bed around and re-classifies some of the un-used resin back to the centre of the filter. As such best keep some spare resin to hand for when it finally fails. Other than that there isn’t one! Who wouldn’t want 30% more free pure water from their filter just by changing to a taller system? Note on most economical usage: We recommend that a final rinse is performed at half mains pressure, just sufficient to create a wave of water over the vehicle, and should be able to be completed in around 45 seconds for a standard family car, little over a minute for a 4x4. This is based on our own usage over the last 4 years. Our resin vessels are made in Europe (many are not) and comprise a PE inner shell and wound fibreglass outer.

We’ve all had to swiftly run round our cars to dry them before water spots form, which are very hard to remove and can badly affect paintwork. And try as you might, washing and drying will cause swirl marks and light surface scratching. Existing in-line water filters are either very expensive or have incredibly short lives, and can waste the casing, which is very environmentally unfriendly. For example, the AquaGleem filter is 2.5 litre capacity, typically retails at £55. That’s 54% more expensive than our unit costing you 38p per litre. The Race Glaze unit costs 25p per litre, as supplied with its first fill of mineral-absorbing resin,and only 10p per litre with subsequent refills ! The new Race Glaze Maxi-Filter uses a durable 11 bar pressure tested fibreglass tank ready filled with 7 litres of premium A1 grade resin (note: some budget filters use sharps – broken reject resin, or are only part filled) and comes ready for you to add standard Hozelock-type connectors (not supplied but available on this website) to begin use immediately. Mains water comes into the unit and is distributed out from the top strainer into the resin bed, falls under pressure and gravity down through the resin bed and as its only outlet is into the bottom strainer and up the pipe, comes through the resin bed to emerge on the outlet side as close to 0 parts per million (ppm) of dissolved solids as possible. Using a hosepipe to wash a car uses approx. 30 litres of water (AutoExpress 21/3/2012), a final rinse only a fraction of that – we estimate 5-7 litres at most. This is a breakthrough in filtered water product for car washing that is proving to be very popular. We recommend that a final rinse is performed at half mains pressure, just sufficient to create a wave of water over the vehicle, and should be able to be completed in around 45 seconds for a standard family car, little over a minute for a 4x4. This is based on our own usage over the last 4 years. Accessories: Water Hardness Meter so you can test the water to see when resin needs replacing, and replacement resin in 7 litre or 25 litre bags. Alternatively, simply send us a sample of your output water and we'll measure it for you and report by email. FREE service for our customers only. All our figures are based on a sensible typical UK hardness figure of 300ppm dissolved solids in Hertfordshire, giving 415 litres of water. You will get much more in softer water areas. OUR PRODUCT REVIEWS There are dozens of reviews of these products and every one is totally genuine. Customers love them ! The product really is that good. If we added all the good things said about them verbally and on Forums we'd have 3 times as many... We have carefully selected these taller vessels, in consultation with a water treatment industry veteran, as wider, dumpier (window cleaners) vessels have a lower efficiency and can’t extract the maximum capacity from the resin. This ends up costing you more money. In our tests, our 7L filter produced 59 litres water per litre of resin, over 20% more efficient than the window cleaner 10L unit which produced 48L per litre of resin. So if you're comparing units, add 20% to the price of the dumpy units. We strongly advise that you check your shed/garage for male adapters and hosepipe-end connectors prior to purchase - though you can buy them from us with your order. WILL WATER SOFTENERS DO THE SAME THING? Water Softeners change dissolved hardness into dissolved sodium bicarbonate which removes limescale. However, if you boil off the resultant water you will have a residue at the end of the process - which will be left on your car if you use softened water to wash it and let it dry in the sun. Our filter totally removes all dissolved solids and there will be nothing left on your car after sun drying. They are different process designed to do different things. Our resin vessels are made in Europe (many are not) and comprise a PE inner shell and wound fibreglass outer. These are high quality, strong units with best quality fittings and top grade resin. NOTE ON SHIPPING OUTSIDE MAINLAND UK These are heavy items and our low standard carriage rate is designed to keep costs down for customers of our standard size car care products. Shipping for these filters outside mainland delivery areas of England, Scotland and Wales is simply too much for us to absorb and unfortunately has to passed onto customers.

Please contact us if you live outside mainland (lowland) UK - the zones where you know couriers charge more to deliver! WARRANTY The product is warranted free of manufacturing defects for 12 months, but the resin media is a consumable and not covered. If the vessel is dropped or falls, warranty on the cap and body is void.

Replacement Water Filter Resin - 7 litre
In Stock
Usually ships in 24 Hours

Our Price: £45.00 (inc VAT)
7 litre bag of top grade replacement resin for Race Glaze Maxi Water Filter. Guaranteed first grade, new, A1 grade resin, not fines or mis-shapes. This is sufficient to replace the resin in your 7 litre filter as originally supplied. It is also exactly the same product. For 14 litre filters you will need 2 bags. When your filtered water starts to leave spots then simply unscrew the top of your filter and dispose of the old resin in your waste bin, rinse out the filter and empty this replacement bag of resin in. Do not let resin fall down the tube, which you have to leave in situ in the centre of the filter - our Refilling Kits include a wide mouth funnel to prevent wastage/spillage, and a handy cap for this pipe. Tap the filter on the ground a couple of times when refilling as this will enable resin to settle down, and you can fill it right to the top (just allow enough for the internal head to seat properly). You may have a little resin left over. If the top is tight, smear a thin film of oil (olive, sunflower) around it to make it easier next time. Costs of the filtered water once you get to replacement stage are of course 55% less than the batch created by the original new filter, at approx. 10p/litre. Replacement resin does have a lifespan of around 2 years. NOTE ON SHIPPING OUTSIDE MAINLAND UK This is a heavy item and our low standard carraige rate is designed to keep costs down for customers of our standard size car care products. Shipping for water filters and replacement resin outside mainland England, Scotland and Wales is simply too much for us to absorb and unfortunately has to passed onto customers. Shipping for a filter and extra resin to Northern Ireland for instance is £22 in total. For resin alone, £16 in total.

If you want to get that 'just snowed' look on your car, with thick, dense snow foam to aid washing and create a spectacular opening to your car washing routine, this is a proven product which should be of great interest to those wishing to step up their personal detailing programme. You'll need a pressure washer and the right adapter for it (see listings) and some Snow Foam (ours is £5 for 500ml, enough to make 10 L of snow solution). This unit is tough, heavier duty than the cheaper, lighter looking models on offer, so entirely suitable for professionals too. Supplied with strong screw-threaded foam container. The connector between the units' head and the adapter to your pressure washer is inset brass in nylon and stainless steel pipe - no plastic thread which can break under weight. Just adjust the nozzle, there are 5 settings and cover your car in foam which will soften dirt as it sits on the vehicle and slowly runs down, taking some with it. This will make the actual hands on wash easier and with less chance of scratching stubborn debris off. This unit benefits from a stainless steel injector which allows a perfect mix of air and solution. Using the head of the unit you can adjust the angle of the stream of snow created. The entire unit is resistant to chemicals and contains a filter which is accessible for cleaning. It is recommended that clean water is run through the attachment when you have finished foaming. Product weight: 432g. If you are unsure which adapter fits other branded pressure washers please contact us. 'Budget' - we used this term when these were sold by us alongside genuine Italian-made PA lances at £47. The market is now flooded with cheap Oriental imports so this SuperDuty Lance is now relatively expensive, but in our opinion will last much longer and gives better results. Cleaning the filter: unscrew the Philips headed small screw on the side of the unit, work the head of the lance off and the white filter will be visible at the end of the assembly. Wash thoroughly and reverse the process. Do not knock out the pins which hold the unit together, this will not give access.

RRP: £42.99
Our Price: £16.99 (inc VAT)
You Save: £26.00 (60%)
Check the status of your Race Glaze Refillable Water Filter with this simple dip-in Electronic TDS water hardness meter. The water meter will provide a single reading of parts per million (ppm) dissolved solids. Regular checks will save a potential walk away from your car to return with it covered in water spots. Once the reading rises to 10 or so you will need to replace resin, as it will rise to 20 or 30ppm then rocket to hundreds of ppm, even higher than your tap water, as the resin media releases stored minerals. Simply press the On button and dip into a carefully cleaned receptacle that has been thoroughly rinsed with the water to be tested - a 'clean' glass from your dishwasher etc will be contaminated and give a false reading. 12 month guarantee. Instructions included in leatherette pouch.
