Testing Viair's 400P & 450P Portable Air Compressors - Four Wheeler Network
We’ve tested an assortment of onboard and portable air systems over the years and one of the companies we’ve had great success with is Viair. Viair offers a range of air systems, which span the spectrum from basic compressors to comprehensive dual-pump and tank combinations. The company even offers Jeep-specific kits. The major advantage of the portable system for us is that it allows us to have a compact air compressor setup for multiple rigs. While Viair does a great job suggesting the correct compressor kit for your rig based on tire size, understanding how the systems work can actually allow you to make the most informed decision. To delve a little further into this, we picked up two of Viair’s premium portable air compressors: the 400P and 450P. The 400P is part of the company’s Heavyweight Series and has a 33 percent duty cycle. The 450P comes from the Extreme Series line of Automatic Portable compressors and boasts a 100 percent duty cycle. Over the course of testing, the 400P was able to clock a best time 2:52 per tire, while the 450P came in at 3:45. This means the 400P was able to fully air four tires in under the 15-minute duty cycle time period. Source: www.fourwheeler.com
