Description of VIAIR 400H Hardmount Compressor: Ultimate Power for Heavy-duty Applications

Product Characteristics

The VIAIR 400H Hardmount Compressor is a powerful and reliable 12-volt air compressor designed for use with tires and wheels. With a maximum working pressure of 150 PSI, this compressor ensures efficient inflation, making it a valuable tool for car owners, off-road enthusiasts, and anyone who needs to maintain proper tire pressure on the go.

Important Parameters

One essential parameter to note is the 150 PSI max working pressure, which guarantees quick and efficient inflation of tires of various sizes. Another important consideration is that the engine must be running during use, as it draws power from the vehicle's battery. This feature ensures continuous operation without worrying about power constraints during longer inflation tasks. The compressor's 12-volt rating ensures compatibility with most standard vehicle power outlets, offering convenience and ease of use. Additionally, the VIAIR 400H is equipped with an auto-shutoff feature that stops inflation automatically when the preset pressure is reached, preventing over-inflation and ensuring safety.

Works best in air compressors and blowers

I bought this to inflate my 35" tires after blowing them at the track for a day. The tire inflation chart is still pretty accurate.

Pros
  • Free for educational use
Cons
  • Upgradeable

Great compressor under the hood.

Great little compressor! I installed it under the hood of my 1999 Nissan Pathfinder and it works great! I use it all the time to quickly inflate tires after deflation and inflate suspension airbags. All in all a great compressor and much cheaper than similar ones from other companies.

Pros
  • Impressive
Cons
  • Not bad

Worth the money compared to cheap.

My compressor is located under the hood of my Wrangler and can get very hot underneath after a day of driving. My previous compressor was a cheap high frequency compressor that overheated and died after two tires so I had to wait for it to cool down before I could finish. This compressor inflates all 4 35" tires from 15 to 36psi in under 15 minutes. No heating problems.

Pros
  • Great design
Cons
  • Poorly thought out

so i'm happy. One star discount per unit arriving ex.

Very fast for a compressor without a motor, but also prone to overheating/cutting out if running for more than 10 minutes at a time. However, this is a trade-off for the extra compressor speed with <100% duty cycle, so don't deduct a star for that. However, it will fill all my 35 x 12.50 r15 tires from 10psi to 25psi just before cutoff, so I'm happy. One star deducted for the unit arriving with a cracked top manifold. VIAIR customer service fixed the problem quickly and free of charge, but…

Pros
  • Ideal for outdoor activities
Cons
  • Cord is shorter than other picks

Just Better - Tires and Wheels

Used a few times on a 5000 mile ride in Baja. You flip the switch, it lights up, pump up the tires. Not as much. So far I haven't worked hard enough to turn off the thermal switch, although it does get hot enough to send you for a pair of gloves. For inflating 35" tires from 18 to 35psi. I didn't know how long it took, but it was good. Looks well built so I installed it under the hood on the fender. end of the lead hose. Went to a hardware store and grabbed some stainless steel fasteners…

Pros
  • Certified
Cons
  • Slightly Crumpled

Great Compressor! - Air Compressors and Inflators

Good air compressor. I installed it under the hood of my 2004 Jeep Wrangler and it's just what I needed. Robust, strong and high quality. Inflates tires better than any of those cheap junk compressors you can find online that you plug into your cigarette lighter. I can say that the manufacturer should make an adjustment for the fuse that he installs on the wiring. The fuse should be next to the battery, but instead the fuse is literally a few feet from the battery. It makes no sense. The fuse…

Pros
  • Stylish and modern design
Cons
  • Functionality
