EWK 22 oz 110 psi Refillable Liquid Spray Can for Brake, Machine & Engine Cleaning

So you should know, usage as an air duster was not its primary purpose when designed. For that purpose its okay, not high pressure, but can work for some light dusting. As for its intended purpose, its awesome. I load it with cleaners and use it when detailing my cars. Seems to make the cleaners more active as it leaves in a foamed state. Nothing ridiculous, its similar to how a can of aerosolised glass cleaner comes out. Holds pressure with no issue for a week. Tops out around 90PSI with a safety valve, so you can't blow it up as long as that valve functions. Robust construction, feels solid. Can be filled by anything with a tire chuck. Bike pump, air compressor, car compressor, etc. The extendable precision nozzle is great for getting a small amount of cleaner into a tight space. Strongly recommend if you have a great cleaner like simple green, but you wish it came in a pressurized can instead of just a spray bottle. Will work with anything not caustic, do not put in bleach or acetate.

Filled with ATF & Acetone to make a penetrating fluid. Worked fine for 15 minutes, then stopped spraying correctly. I am well aware Acetone eats plastics, but the plastics were not melted or anything, nor would I expect it to be for a sprayer like this. It sprayed somewhat thru the "flip down" mode, but when flipped up (straw mode), nothing happened. The o-ring in the flip-up sprayer fell out too. Piece of chinese junk. Have since purchased a Sure-shot (not big can style) brand of this style and it works perfect.

I have two of the earlier version of these - press button not trigger. They do what they're designed for - spray low viscosity (thin) liquids. Negative criticisms miss the point. Some Notes.. 1. This is not an air duster and not meant to be. Real air dusters use a chemical that turns to liquid at pressure - look it up - and will blast out a gas (it's NOT air!!) for several minutes. Try it with this and you'll get a few seconds only. Don't buy it if you want a gas duster and don't whine if you do and are disappointed 2. Don't over-pressurise it. It says 90 to 110psi and is fine at that. There's a pressure release valve so it should not be possible to exceed this. If you defeat the valve and use higher pressures expect it to explode and possibly cause serious injury. Don't do it!! 3. It's aluminium. Don't use corrosive chemicals because many will eat into the aluminium, weaken the can and cause it to rupture. Stick to solvents and lubricants only. Now comments on how well it works when used for its intended purpose.. Generally it does what it's supposed to do and not only does it save a fortune in aerosol cans but it also allows you to spray custom mixes...1:1 WD40 and Fluid Film say.....but there are some niggles with it. 1. No filter on the pickup tube - so if you get any contaminants in there it will clog the nozzle. This is a real pain. Either use very clean fluids or pour them in through a fine mesh filter. Or buy a fine mesh fuel filter and stick it on the end of the pickup tube ..see photo. This works if used upright but if you invert the can it switches to a different inlet and will bypass the filter 2. The plastic around the base of the steel spray tube eventually crack and it leaks. This is is a killer and a major complaint. I have two of these and both failed the same way. Because it's so useful I fixed it by pulling out the steel nozzle to allow the crack to close, wrapping a fine stainless steel mesh around the plastic and using a hot iron (plastic welder) to embed the mesh into the plastic and hold the crack closed and reinserted the steel nozzle. Been OK for over a year now but you shouldn't have to do this!!! Bad design 3. Loses pressure as it empties. But his is really a minor thing and hard to design out if you're a manufacturer. Cause - as you're using compressed air not a volatile propellant as in a normal spray can then as the can empties the pressure will drop. The more liquid you put in the less room for air and the more the pressure drops. Best to fill say 50% and pressure will then only drop 50% from full to empty....or just top up pressure occasionally from an air compressor. Overall very useful but some flaws. Worth buying despite the somewhat high selling price

Warning: Dork Review Ahead. Holds 83.8% of pressures tested up to 150 PSI. Well made. God help you though if you disassemble it as I did. Wow! Lot of parts. Rusting levels also amazingly low if stored pressurized. Look, if you read this far, you are clearly interested so buy it. $2 more than a can of pressurized poison for 1/5 capacity, just do it. 1/5 is an estimate but come on yo

Well made and exactly what I was looking for to replace canned air that has become too expensive. Unfortunately it fails do to lack of capacity/PSI. It only be filled to 90psi which gives about 20 seconds of marginal output. The design and construction of bottle are excellent, so wanted it to work.

Update 3/20/24: increased the open volume from about 1/5 to 1/3 and the extra pressurized volume allows for proper operation (which makes sense). Operator error on the initial now it works great. This would be a great tool, but mine will not hold pressure. Leaves through the nozzle almost as quickly as it’s filled. Drops from 100-10psi in about 15 seconds. I’d prefer to contact customer support to do this but the website (not through Amazon) requires you to create an account to see their contact info.

Only giving this a 1 star because it won't let me give it 0 stars Like all the other bad reviews this one is no different. Filled with brake cleaner and worked great the first time, picked it up not 2 minutes later and didn't work at all. pulled trigger assembly apart and every O-ring swelled or split. Replaced the O-rings and emptied, cleaned and filled with WD-40, same thing. Modified the spray section of the nozzle(the 2 piece sprayer is a joke) to spray straight through and can use it for wd-40 at least. Last one I will ever buy from this company.

I got this to use as a sand blower for the stuff we take to the beach. Needless to say it does not work for that purpose. The build quality is decent but functionality is lacking. Charged at the max 90PSI it can withstand the air will be consumed in less than 30 seconds of continuous use. You pay 27$+tax to get 30 seconds of air to clean your stuff. I don't think that's a good deal. Also, the pressure of the air is very low. I think they have some sort of regulator inside and it is terrible at dealing with blow cleaning. I would not recommend this item. not for air dusting or anything of the sort.

I have veen looking for a profuct like this for a while, and this one really exceeded my expectations in terms of quality and functionality. Delivery took some time, but I am very happy overall. Highly recommended to anyone on the market for a portable spray cans

Very well built and works perfectly

We received this sprayer on a Monday , filled it with brake clean , added air , worked fine , put it away and then one of my workers went to use it on Wednesday and nothing sprayed out. He said the brake clean ate the seals and it will not hold pressure. Amazon will refund my money if I drop it off at a UPS location , well , its not feasible for me to take an hour off work to drive 50 kms to a UPS location. Not every town has a UPS!!!!!!

Great product until you need replacement parts

Really appreciate how well this works. Much cheaper to buy bulk fluids and add them into this container. I make my own diy cleaner for intake valves and this works amazing for spraying it on.
