CAS Supply Valve

CAE Exhaust Valve

CAS:The CAS is a spun steel adjustable supply disc value manufactured in a range from 100mm through 125mm, 150mm, 160mm up to 200mm diametre. Suitable for volumes of up to 80 litres they are typically used to ventilate lobby’s, toilets and washrooms, bedrooms etc.

The units are adjustable by rotating the cen-tre disc to either increase or decrease the throw of the grille. These units are fitted by screens replacing a fixed steel collar, the body of the grille is then fitted by a cam ac-tion to allow removal for cleaning at a later d�te.

The units are polyester epoxy powder coated and generally finished in white 9010 matt.

CAE:CAE is the matching extract valve suit-able for similar areas such as toilet extract, washrooms and bedrooms. Available in a matching range of sizes of 100mm, 125mm, 150mm, 160mm and 200mm.

These units are fitted by screens replacing a fixed steel collar, the body of the grille is then fitted by a cam action to allow removal for cleaning at a later date.

The units are polyester epoxy powder coat-ed and generally finished in white 9010 matt. All units can be supplied with an optional cir-cular fire core where fire rating is required.E
