GT125 Controller Fan and Filter Kit 420m3

This kit hands the GT125 set a brain. The fan carries a built-in thermostat and a minimum speed setting. When the lights go off and the room cools, it eases back; when they fire up and heat builds, it ramps. Output reaches 420m3 per hour through a 125mm flange on an EBM Papst motor.

The matching filter is a Prima Klima K2601 flat, ideal at 360m3 per hour, up to 480m3 per hour, 400mm tall. Set your target once and the thermostat holds it, no dial-twiddling through the day. It fits a single light around the 600-watt mark. Join fan to filter with a collar and hang the fan from the supplied bracket.
