How Does It Work?
When water collects in the body, the float rises and opens the outlet. After the water is discharged the float drops and closes the outlet, so no compressed air is lost.
Applications
- Compressed air receivers
- Compressed air lines
Key Features
- Drains water with no air loss
- No electricity needed
- Ductile iron body, stainless internals
- Threaded or flanged
Selection and Installation
Install the drain at the lowest point of the receiver or line. The “UP” mark on the cover must face upwards, otherwise the trap will not work. Flow is left to right.
