VIAIR 400P Portable Compressor
At a Glance
- 47 LPM flow rate is one of the fastest in the mid-range bracket
- 150 PSI maximum handles high-pressure tyres on larger 4WDs

- Australian brand with good retailer availability
- Includes 6-metre hose — long enough for all four tyres without moving

Frequently Asked Questions
+ Is the ARB CKMTA12 worth $250 more than the Bushranger?
For serious 4WD tourers, yes. The ARB CKMTA12 is 60% faster (72 vs 45 LPM), runs at 100% duty cycle (vs 33%), and is backed by ARB's national service network. Over 5+ years of regular use, the ARB's reliability and speed advantage pays for the premium. For occasional 4WDers doing 5-10 trips per year, the Bushranger is a reasonable saving.
+ ARB CKMA12 or CKMTA12 — which should I buy?
Get the CKMA12 (single motor) if you tour solo or in a pair, cost is a factor, and 42 LPM (5–7 minutes per tyre) is acceptable. Get the CKMTA12 (twin motor) if you tour in groups, value your time, or want maximum reliability for extended remote trips. Both have identical 100% duty cycle and quality — the only difference is flow rate and price.
