Rack actuator Aprifire

Aprifire is solution for automating, within industrial applications, outward opening and bottom-hung windows and domes, sheds and skylights. It is a linear operator for smoke and heat extraction. This is why it has been designed and produced to operate under the difficult conditions after a fire. Aprifire is fitted with ASR (Anti Reverse System), a closure prevention safety system. Aprifire can be adapted and adjusted to fit any frame thanks to the side guides in the rack tube profile. With just a few simple operations Aprifire can be converted into a side dovetail guide. Gear motor body: lower die-cast aluminium part painted with heat-set non-toxic harmless powder paint (RAL 7035 colour); upper nylon-loaded glass part, 4 mm thick, with gasket housing. Fitted with 2x0.5 mm2 power supply cable with silicon sheathing, connected internally on the operator.
