FST — Float Type Steam Trap
Mechanical float trap for continuous condensate discharge with automatic air and non-condensable removal.
Product overview
A ball-float trap that discharges condensate as fast as it forms, holding a water seal at all times so live steam does not pass. An integral air vent releases air and non-condensable gases that would otherwise blanket the heat-transfer surface.
The problem it solves
Intermittent or delayed condensate removal floods the heating surface, drops the effective heat-transfer area and destabilises temperature control. Trapped air does the same thing more quietly, and is often blamed on the steam supply.
Working principle
Condensate entering the body raises a float linked to the discharge valve, so the valve opening tracks the incoming load continuously. Air collecting at the top of the body opens a separate thermostatic vent, which closes again as steam reaches it.
