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
