Fit a VRX vent-restrictor to your EXT pump if you will vent the pump when the pump speed is above 50% of full rotational speed. The vent-restrictor restricts the flow-rate of the vent gas into the EXT pump. You can also use the VRX to replace the standard restrictor supplied with the PRX10 purge restrictor to obtain a different purge rate.Note that the EXT250M pump is supplied with a VRX10 vent-restrictor fitted in the vent and purge ports.You can fit the vent-restrictor to the TAV vent-valve, to the vent-port adaptor or directly to the vent or purge port of the EXT255H and EXT250M pumps.
