MPU – Medium Purge Unit is mounted in a solid aluminium and vinyl covered box with castors.

A valved test point is included for the connection of a Gas Analyser such as a Gascoseeker. For monitoring the gas pressures or, if needed, for testing the hose assembly for tightness. The flow meter measures the gas velocity as a flow as given in UP/1. Press the panel on the meter index to change from flow to flow rate readings.
