A filtered and lubricated air supply is essential. The speed of the pump is controlled by fitting a regulator at the inlet. A speed range of approximately 5:1 is normally obtainable.

Any pumphead and tubing combination can be used for 0 to 2 bar (0 to 30 psi) operation. For 30 to 60psi (2 to 4 bar) operation, use a 620RE or 6530RE4 pumphead fitted with a Marprene®, Bioprene® or Sta-Pure® element, or a 620R pumphead fitted with continuous Sta-Pure® tubing.
