VIAIR 90C compressor (air pump) offers a light duty solution for smaller air requirements. These compact compressors and are meant to fill no larger than a 1.0 gallon air tank. These products are used on mobile competition robots and outdoor equipment.

Hardware Included:

Pump (1), Vibration Isolators (4), Screw (4), Nut (4), Washer (8), Lock Washer (4)

Performance Test:

Manufacturer Specifications as of 2/2020: 1.03 CFM
Results of 2014 AndyMark bench test for determining CFM rates:

Pressure	Flow rate	Amp Draw
0 psi	0.88 cfm	7 amps
10	0.50	8
20	0.43	8
30	0.36	9
40	0.30	9
50	0.27	9
60	0.25	10
70	0.24	10
80	0.24	10
90	0.23	11
100	0.22	11
110	0.22	10

For this test, flow rate was determined by this calculation:
- (change of pressure) / 14.7 psi * volume of system / time elapsed
- For example, at 10 psi:
  - change of pressure = 10 psi
  - volume of system = 0.1095 cubic feet
  - time elapsed = 9 seconds (0.15 minutes)
  - CFM = 10 psi / 14.7 psi * 0.1095 cubic feet / 0.15 minute = 0.50 cfm

Fill Rate for Number of Clippard tanks (574 ml) to fill from 0 to 110 psi:

1 Tank = 34 Seconds
2 Tanks = 64 Seconds
3 Tanks = 103 Seconds
4 Tanks = 140 Seconds
5 Tanks = 176 Seconds
