Ultra Duster Industrial Strength Compressed Air Duster Cleaner 10 oz., 12/Pack (UDS-10P12)

Works great at a reasonable price

Good product. I use it to blow moisture out of my cannula as l am on oxygen therapy.

All of the cans arrived seemingly unbroken, and as I didn’t want to remove the plastic covering on the caps until ready to use, I only tested one can and did a visual, with shaking each can, to insure none were empty. This is my first brush with blue cap Dust Off, but have had great success with the black cap Falcon so figured they were worth trying (and being less expensive helped too). Only difference that “might” be found is the can cools somewhat quicker, but not instant freeze, which when happens slows/decreases the pressurized “air”, but the air pressure works just as forcefully as other brands I’ve used and you aren’t supposed to use a continuous blast anyway - plus there is a big bonus to these as well, as unlike the Office Depot brand that sells for less, these don’t frost up instantly, and are Not overly filled with bitterant, so they don’t spit liquid out all over the place, like a keyboard, in the computer/DVR vents, or on the TV screen when dusting out the frame after wiping it down, if not held perfectly level when used. Overall so far,, glad I made this purchase.

Arrived in a prompt manner, in original factory box inside another box so shippers could not hurt them. Best price I could find.

I don't use this as a spray, I use it in several of my vehicles A/C to replace R134a. This brand is always HFC-152a where other brands may use one of 3 different HFCs. You don't want a mix so stick with Ultra-Duster. This is colder (barely) than R-134a and the high-side pressure is lower than R134a at high temperatures; easier on your compressor. If you do swap to this, put a good vacuum on your A/C system for several hours. Legally, you're required to recapture all of the R134a because it's been declared a greenhouse gas 30x more than carbon dioxide, oddly soon after the DuPont patent expired. R12 was fine with the ozone until the DuPont patent expired. Once you switch to this, you can forget about the legal stuff, it's meant to be sprayed into the atmosphere. And it's currently under $5/can. My trucks use 3 cans for a total fill, little foreign cars take two cans. I believe some European manufacturers are currently using it. If you attempt this, use gauges. Low side should be under 50psi, high side around 200+psi. 250psi is too high. Be sure the radiator fan is running or the high side will look high but will drop once the fan runs. It's compatible with PAG oil so it can replace R134a. DO NOT replace R-12 which uses mineral oil unless you flush the entire system, drain the compressor, etc. You'd need to be desperate but, considering the price of R-12, I'm getting there. I have two Rangers that have been running Ultra Duster for over 50K miles each with zero problems. Do your own research before putting this in your car. It works in mine but I can't be responsible for yours. Edit- Don't replace R134a for no reason. If it's working, leave it alone. All of the vehicles I've put it into had more than minor problems which warranted a switch.

So I build and service computers and other electronics as a hobby/side business, and this is actually the best air duster I have used overall. This has significantly more pressure than other canisters I've used. The only issue I have is some of the straw-like extenders don't like to stay in the can and shoot out randomly.

GREAY PRODUCT

This stuff is awesome for the price. I drive a jeep and trust me it gets dirty a lot on the inside and it's hard to get in all the tiny areas but this stuff gets the job done. However, this time my package hasn't arrived yet.
