Compressed Air Drain Trap

Description

The Monnier Dri-Line Mk3 is an automatic float actuated drain

used to drain air line drain legs and filters.

It is a normally open valve that is rated for use up to 17 bar g

and 80°C. The valve is held closed by line pressure.

The pilot valve is never submerged in water, and its discharge

is operated by system air pressure, producing a strong on-off

action. The float which is extremely light, can't leak or hold fluid.

All parts are corrosion proof.

The unit has a manual override to check proper functioning.

Discharge is easily piped to remote locations. When the

compressed air system is shut down, the valve returns to its

normally open condition and water will drain away by gravity.
