Engineering Principles & Working Mechanism

Mechanical float-type automatic condensate drains are rugged, reliable drainage devices engineered to evacuate accumulated liquid condensate from line filters, moisture separators, and air receivers completely without electrical power.

As liquid accumulates in the aluminum reservoir bowl, buoyant force elevates the precision float mechanism, lifting the direct-acting discharge seal off its seat. Once liquid evacuates, gravity and internal line pressure immediately reseat the seal, preventing any waste of compressed air. Float drains are the ideal choice for remote piping drops lacking power outlets, washdown areas, and explosive atmospheres (ATEX) where electrical coils are restricted.

At HAVKOM Engineering, we supply heavy-duty corrosion-resistant mechanical float drains equipped with integrated stainless strainers and manual testing levers, complete with expert installation and seal maintenance.

Frequently Asked Questions

Does a float-type condensate drain require electrical power?

No, it operates 100% mechanically based on hydrostatic buoyancy. The rising water lifts the float to open the drain port without any electrical wiring.

Where is a mechanical float drain best utilized?

It is ideal for inline filter housings, remote pipe headers lacking power outlets, outdoor installations, and hazardous ex-proof zones.
