Compressed Air Charts

All H.E. Anderson Injector pumps can be run using compressed air instead of water. This eliminates waste water and allows the injector to work at pressures below 30psi. Use the charts below to determine how large an air compressor is required to power your unit.

Compressed Air Charts for D Series Units

D Series charts apply to portable and wall mount models also.

DB Models	Pump Head	CFM "Free Air" Required
DB100	P2-HC	2.5 CFM
DB200	P2-HC	2.5 CFM
DB400	A10-VCP	2.5 CFM
DB1000	A3-VCP	2.0 CFM
DB1200	P1-BA	2.5 CFM

DD Models	Pump Head	CFM "Free Air" Required
DD100	H4-HD	3.0 CFM
DD200	H2-HD	2.5 CFM
DD400	A10-VCP	2.5 CFM
DD1000	A3-VCP	2.0 CFM
DB1200	P1-BA	2.5 CFM

Compressed Air Charts for J Series Units

Number of Pump Heads	Pump Head Size	CFM "Free Air" Required
2 Pumpers	H4-HD	9.0 CFM
3 Pumpers	H4-HD	12 CFM
4 Pumpers	H4-HD	15.5 CFM
5 Pumpers	H4-HD	18.5 CFM
6 Pumpers	H4-HD	22.0 CFM

Note:

This chart assumes that the injector is operating at 40 stokes per minute and the air pressure supplied is at 125 psi. If the injector does not stroke as often then less compressed air is required. Also if the injector does not require 125 psi, a regulator can be used to reduce the amount of compressed air required.

A compressed air dryer should be used with the air compressor. If the compressed air is not dry it can lead to icing in the manifold causing the unit to operate incorrectly or be damaged.
