Overfill Protection Devices - Tank-Full Shut-Off (Pneumatic)
Tank-Full Shut-Off (Pneumatic)
Shuts off fluid supply to remediation tanks when full.
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.|
