AirTech VCX 60 - Vacuum Connections

1.5 Vacuum Connections
Use a pipe size that is at least the size of the pump outlet connection. Smaller pipe lines result in reduced
pump capacity.
Pumps operating in parallel on a common main line should have a manual or automatic shut-off valve or
positive action check valve installed in the suction line adjacent to the pump suction flange. The built-in
anti-suck back valve should not be used as a shut-off valve for the vacuum system. Remove the plastic
protective cap from the inlet port prior to connection of pump to the system. Should process gas contain
dust or other foreign particles, a suitable in line (inlet) filter should be connected to the inlet port. Contact
Airtech for recommendations.
