Rack-and-pinion vent drive with true position feedback and wind protection.
A rack-and-pinion roof vent drive with absolute position feedback, wind-side logic and a mechanical safety close that does not depend on the control network.
Indicative lead time: 6 - 8 weeks
Many older installations estimate vent position from motor run time. Slip, wind load and mechanical wear make that estimate drift, and the climate controller ends up regulating against a number that is no longer true. The ventilation drive reports absolute encoder position, so the control loop and the reality agree.
Opening the windward vents in a stiff breeze does not ventilate, it pressurises. Lee and wind side are driven independently so the strategy can favour the leeward opening and hold the windward side closed above a wind threshold.
Storm protection is wired as an independent circuit. If the controller, the network or the building management system fails, the vents still close.
