Product Description
Designed for aluminium or timber framed vents measuring up to 60cm square, lifting a load of up to 6kg.
This opener provides a maximum opening distance of 30cm and can be set to start opening at approx. 75*F (24*C).
The opener is operated by a stainless steel cylinder containing a mineral wax which expands with heat; this pushes a piston causing the vent to open. As the temperature falls the wax contracts and a strong stainless steel spring closes the opener.
