Product Detail

Product Detail

The product consists of an internal ventilator with adjustable closures to regulate incoming air flow and an external canopy with integral fly screen.

Internal ventilator

This is injection moulded in PVC-U, with UV resistant Acetal spring clips that enable the ventilators to be firmly snapped into the routered slot in the profile. The installation of this vent provides time cost savings when compared with 'screw fitting' alternatives.

The closure plate has a positive action and multiple units in the 4000 version provide control of airflow.

A variety of custom fixing clips are available to offset the ventilator vertically relative to the 10mm slot for applications such as sash windows, where space is at a premium. These give offsets of +/- 2mm.

External canopy

This is complimentary to the interior unit and features the same materials and fixing methods. The canopy has an integral fly screen. A flat grill is available
