The VIAIR 300P and 450P Portable Air Compressors – Item of the Day — 7 Comments

  1. Jack, I’ve been interested in air compressors for a few months and am very glad you brought this item up as I’m ignorant about them.

    You also introduced me to the come Along, and lots of other tools. As I was practicing with my come along I started wondering what other things you could do with it? I mean, there has just got to be a lot of things that these various tools can be used for other than one thing and I am sure I’m missing opportunities.

    Could you do a show one time on various uses for tools you talk about? Air compressor can fill up tires, but what else can it do? Come along can move logs but what else can it do? Etc. etc. I think it’s be incredibly interesting to learn.

    Thanks sir!

  2. I bought the Q Industries HV50 about 5 years ago for $55. Very happy with it. Currently it is $85 on amazon though. Too much. I noticed that the MasterFlow MF-1050 looks identical though and according to comments it is the same thing and that one is going for $60. I’d go that route if the extra $26 doesn’t hurt too much. The MF-1050 clips directly onto the battery which gives it twice the amps and power than the HV35 gets when plugged in to the cigarette lighter.

    My experience with the HV50 is good. I’ve dropped it several times onto concrete 2-3 feet up. The plastic piece over the wiring and power switch keeps shattering and I keep having to super glue it back together. But it always does the job I need it to do.

    Unrelated “protip”: I glued a piece of fabric or gauze to the back of the plastic panel to help keep the pieces together. This also helps make it stronger.

  3. The 400P-RV is on sale through Amazon for under $150.00. It’s only a 33% duty cycle, like to 300P, but has most of features of the 450P. It’s rated for 40 minutes of continuous, which is almost three times as long as the 300P, and also includes the auto-off at 150 psi like the 450P. The RV version of the kit also includes an additional length of air hose, tire inflation wand (similar to the ones found on gas station air compressor stations), and several inflation tips for other applications, such as filling balls, etc.

    For a sale price of only $20 more than the standard 350P set, that’s a pretty hard deal to beat. If you’ve had your eye on one of these, but was holding off because of the price, as I was, now might be the opportune moment. I know I just placed my order.

  4. friend at work had a screw in tire so he was going to take it off bring it into factory to fix it.

    pulled out viair, and repair kit he was able to fix it and about 15 minutes during lunch and drive to the tire shop for a permanent fix. easily handles topping off tires on my 3/4 ton truck.
