Expiratory Valve (Plastic)

LIMITED AVAILABILITY

EXPIRATORY VALVE (Plastic) is a valved angle mount which should be mounted directly on the mask and is a purely 1way system.

I've used is on my "Science Project" to remove all exhaled air to atmosphere. The pressure needed is low.

This essentially features an Inlet Valve and an Exhaust Valve and will flow air only 1way.
