Float Valve Assembly for Evaporative Coolers

The Essick Air Products FL-3/8 is a float valve assembly designed for ducted evaporative coolers. It regulates water level inside the unit using a metal and plastic construction. The package includes the arm, float, screw and stem needed for installation. This component replaces a worn or damaged valve to restore proper water control.

For Maintenance on Ducted Evaporative Coolers

This part suits owners or technicians servicing a ducted evaporative cooler that uses this specific float valve design. It is not for use with air conditioners, humidifiers or other HVAC equipment that rely on different water inlet mechanisms. Buyers needing electronic or solenoid water controls should look at other components. The assembly addresses mechanical float operation only.

Mechanical Float Operation with Included Hardware

The valve operates through a mechanical float that rises and falls with the water level to open or close the inlet. All necessary hardware — arm, float, screw and stem — is supplied in the box. This self-contained design allows direct replacement without sourcing separate pieces. Correct water regulation depends on this mechanical action.
