VIAIR 440P Portable Compressor Kit - Perfect for On-the-Go Tire Inflation

Nick: I've had this for over a year now. Used it for adjusting the pressure in my truck for towing when traveling. I really like the combination bleed off and fill fitting. Quick to set up and fills tires quick. I've also used it to fill tires on dead vehicles so they can be moved. Works awesome and hasn't skipped a beat yet. Gets hot during use but thats to be expected with something that pumps out that much air.

benton lang bailey: This little compressor does exactly what it is supposed to. It airs up the tires on my gladiator nicely and quickly. It has also been handy for around the house projects, swimming pool, inflatable boats. My complaints are that the short coiled up hose that is included makes setup take longer then actually inflating the tires, (mostly the rear tires are a fight). And the odd ball fitting that is used really makes only the included hose usable with it. It is changeable and I will be doing it to make it more usable.

Matthew LO Giacco: Had a 300p series that lasted well over 8 years of use. This 440p is no joke it works great for my airing up my 3/4 ton if/when needed in quick fashion. Nice carrying case and very happy it came with adapters for other inflatables

Aaron: Pumped up all 4 tires, 245/75R16 (30.5") from 25 to 60 in a few minutes each. Compressor was still cool enough to touch. Easily reached all 4 tires on my 20 ft long campervan.

Again pumped up 2 tires on a freind's van and 4 tires on mine. Just had it off a couple minutes between vans. Got slightly hot this time but still able to put it away. I don't use the bulky case.

Antoine: Wasn't sure to spend this much money but hey totally worth it. Inflate my pick up tire from 20 psi to 45 in less than a minute and its 275/70r17. A bit heavy but sturdy and not noisy.

fernando: this compressor is pretty fast compared to others in its class. its heavier and its a little larger than i expected but i like the fact that it cut down my airing up time in half. i can refill each 33" tire from 12 psi to 35 psi in about 2 min 20 seconds. the gauge is off by about 10 psi but the instructions warn you that you have to turn the air compressor off to get an accurate reading. i just simply remember that it reads 10 psi more when turned on and turn it off when it gets 10 psi above the desired pressure. the oversize quick release fitting is nice because it keeps you from burning your hand due to the hose getting extremely hot after use. the carrying bag is nice but its a little on the big side. i could easily fit everything including the hose in the main pouch. it could be a lot cheaper considering its made in China like the rest of the portable air compressors out there but i guess you are paying for the viair name brand. all in all i am satisfied with the purchase.

Amazon Customer: I bought this to air up tires after off-roading. Airs up stock 32” Rubicon tires from 20 to 37 PSI in about a minute per tire. The product does get hot. Needs time to cool, but works great. in Line pressure gauge reads a little higher than my spot check gauge, and doesn’t give accurate reading while filling, but have found that once it reads 50 psi while running, it’s about up to street pressure. Definitely recommend this model for the CFM rating, which is why I bought this model. Topping off a typical vehicle tire takes even less time, maybe 20 seconds. Great product. A little bulky and unfortunately just a little big to fit under the back seat of a Wrangler Unlimited. But the positives more than make up for that. The 90 degree fitting for the tire valve could be a little longer, sometimes need to turn a certain way to get good seal and often touching the rim, straight type filling neck would be THE ONLY recommendation I would make. This could be an issue with a bead lock rim.

Mac: Does exactly what I wanted. Quickly airs up 35" tires on my jeep. Can bring all 4 up from 5-10lbs to 20lbs in about 8 minutes. Would buy it again and recommend to others. I'm interested to see how it performs in the summer heat. So far heat has been a non issue as it's been winter here and the wheeling we've done has been in snow. Added benefit you can toss some snow on it if you think it's getting hot. ( I'm sure that isn't recommended in the manual- so do at your on risk lol )

My only problem is now I'm airing up everyone else's tires too!

Amazon Customer: The good news is VIAIR has a lot of compressors. The bad news is they have a lot of compressors! I researched most all of them and frankly almost over looked this one! Without writting a book I picked this one for the following. 1. 3/8 inch connectors as opposed to 1/4 inch on the other units. This allows the use of higher quality hoses etc. Note that the hose with this unit has no "stay out of sun" warnings and should not kink as others have reported. This is an emergency unit and the last thing I want in 5 years is a bad hose. I have had the "yellow" 1/4 in. hoses and they are pretty flimsy especially if bent wrong. 2. 3.0 CFM capacity is 20% to 50% above the 88p, 400p and 450p. While duty capacity is limited to 33% at the high CFM rate fill times should be very quick. I intend to use this for emergency use on small truck or car tires and want to limit exposure times on the road side. 3. Large battery clips will attach to the regular battery post without modification (unlike the 88p) and the heavy gauge wire should hold up. I have had cheap units with skinny wires and was always fearfull of breakage or pulling loose. Plus in the middle of the night or with a...
