Curtain Controller
Choose between two models of Auto-Curtains and two models of automated Curtain Controllers to maintain precise control of the environment in naturally ventilated buildings. Available in a variety of curtain travel speeds, both models feature heavy-duty construction with galvanized housings.

		Drive Block Assembly The Curtain Controller drive block assembly features a nylon insert in a heavy-duty powder coated weld. The removable nylon insert simplifies maintenance, decreases friction and provides wear characteristics superior to conventional brass drive blocks. UHMW polyethylene guide wheels insure smooth travel, proper alignment and stability of the drive block in the machine.

		Direct Drive Gear Motor The Curtain Controller utilizes a threaded block and drive screw directly coupled to a direct drive gear motor.

		Latch Out Switches Adjustable latch out switches can be installed in multiple locations to energize and de-energize a variety of equipment.

		Limit Switches Isolated primary and secondary limit switches allow for back-up protection. New one-piece, galvanized, liftoff cover makes for ease of service. Plastic water resistant junction box is accessible from the outside of the curtain controller.

		Optional Potentiometer Optional shaft mounted potentiometer provides an accurate and immediate signal to indicate movement and position of the drive. The potentiometer can be wired to a PF-6 inlet-positioning module to allow precise control of air inlets or curtains based on temperature rather than static pressure.
