EWK Patented Aluminum Refillable Aerosol Spray Can, Pneumatic Sprayer for Lubrication and Anti-Rust

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

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.

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.

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!!!!!!

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.

Great product until you need replacement parts
