Pressure Connections
The input signal connection is 1/4 NPT. The supply and output connections are 1/2 NPT (minimum pipe size
recommended for nipple mounting is 1/2 NPT). Connections to the volume booster should be made as indicated in
figure 3. Connections for typical applications are shown in figures 4 and 5. Ensure that the piping is of proper size to
meet the capacity demands of the booster and that you equip the actuator with properly sized input connections.
Supply Pressure
Supply pressure must be filtered, clean, dry air or noncorrosive gas.
WARNING
If a flammable or hazardous gas is to be used as the supply pressure medium, personal injury, property damage or
equipment damage could result from fire or explosion of accumulated gas or from contact with hazardous gas. The volume
booster has no provision for piping away the vented exhaust gas. Therefore, do not use flammable or otherwise hazardous
gas as a supply medium unless the unit is in a well‐ventilated area and all ignition sources have been removed.
Exhaust Ports
Exhaust to the atmosphere is through exhaust ports in the side of the unit. Keep the exhaust ports free of any
obstructions or foreign materials that might clog them.
