I noticed AndyMark has come out with a new compressor as an alternate to the Viair 00090.
The primary claims about it seem to be that it has a higher 1.1 CFM output (legal limit per 2016 R79), and that it has a higher rated duty cycle (15% vs 9% on the Viair).
A quick glance at some of the specifications makes me doubt the value here though.
1.1 Pump:
- 3.37 lbs
- 15% Duty Cycle
- 1.1 cfm @ 0 psi
- 0.26 cfm @ 100psi
- Dimensions: 3.27"x6.75"x5.25"
- ~31 sec - Claimed time to fill (1) 574ml tank 0-110 psi
Viair 090:
- 2.4 lbs
- 9% Duty Cycle
- 0.88 cfm @ 0 psi
- 0.39 cfm @ 100psi
- Dimensions: 2.11"x4.53"x5.94"
- ~13 sec - Claimed time to fill (1) 574ml tank 0-120 psi
Based on the listed specifications, the new one has a little better duty cycle - which may make it a little more reliable. Otherwise it weighs nearly a pound more, takes up more space, and has ~30% less volume output at 100psi - where it matters for topping off during the match. Even the stated fill times for a tank are worse than the Viair.
I like the look of the larger heatsink, but between the weight penalty and the lower ouptut at pressure, I'm not seeing the advantage.
Am I missing something here?
