TR-75713 DGSI F.A.P. Plus ZW Pneumatic Overfill Protection Device for 1 to 5 pumps | DGSI Slope Indicator Environmental Products

Tank-Full Shut-Off (pneumatic) - Shuts off fluid supply to remediation tanks when full. 

This device is installed on the recovery tank or drum to prevent overfilling of the product storage vessel. The main air is supplied to the inlet side of the overfill device and the outlet air supply to the F.A.P. Plus ZW pump. The overfill device is triggered by increased fluid levels in the recovery tank and mechanically shuts-off the air supply to the F.A.P. Plus ZW pump. The standard overfill device can be used with up to five pumps and installs into a standard 2-in bung.


This pneumatic device is activated by a high liquid level in the recovery tank. Once activated, it shuts the air supply to the pneumatic pump, stopping fluid discharge to the tank.

Note 1: The use of synthetic oil in an air compressor can cause chemical deterioration of components In the Control Valve that could result in failure of the unit.

Note 2: The TR- 75713 can support up to six FAP+ZW skimmer pumps. Consult with a factory representative before using a larger number.

Note 3: If the unit must be operated in temperatures less than 33°F., then a desiccant air dryer must be used to reduce the dew point of the moisture in the compressed gas to a lower temperature than ambient. If using inert compressed gas, check with the supplier concerning the dew point temperature of the inert gas supplier.
