UL/FM Drivers with PLD Suction Pressure Control

All Clarke PLD engines meet NFPA-20 and NSPS Emission Limits for USA. Our engines are certified by Underwriters Laboratories (ULl & cUL). Factory Mutual (FM) pending.

When choosing an engine for your application, remember that each engine has a minimum speed of operation. To determine if the Clarke PLD engine can reduce enough pressure for your installation, review your project either by using our
