Air Traps

MIYAWAKI Air Traps are designed for continuous discharge of condensate from air piping, receiver tanks, gas and compressed air systems.

Depending on the operating conditions and applications a wide range of various types of air traps is available. Most of the traps can be fitted with a pressure - balancing line to ensure air can escape from the trap body to prevent air locking. Pressure-balancing lines are usually not necessary, if the air trap is installed directly below the equipment to be drained or if the trap is installed vertically.

MIYAWAKI offers different seat materials and various body materials (including stainless steel) for draining special gas applications.

Operating principle

air cold condensate
At start up condensate enters the air trap. The float is rising and the condensate will be discharged through the wide open valve. Air, which usually enters the trap body together with the condensate, will accumulate in the upper part of the trap body. To prevent air locking, a pressurebalancing line connects the upper part of the trap with the drained equipment, so that the air can escape easily from the trap body. Condensate continuously enters the air trap. Depending on the condensate amount the float will move upwards or downwards to open or close the valve seat. Usually a certain liquid level will be maintained in the trap body and condensate will be discharged continuously. Air will leave the trap body through the pressure-balancing line.
