Curtain Machines and Curtain Machine Parts

Curtain Controller
Our most popular machine is the Curtain Controller. This is a screw driven automated curtain machine with a heavy duty 15, 30, or 60 RPM motor. Multidirectional, frame mounted,
header pulleys and latch out assembly come standard.  (Thermostat controls, electronic controls and extra bracket kits sold separately.)

Auto Curtain
AP’s Auto Curtain operates on a cable system by winching a cable around a grooved drum controlled by a thermostat and timer. A 506S version uses a sprocket and
chain drive that wraps the curtain, or door drop cords, around a building length pipe.

Auto Curtain 506

Operates curtains on a cable system by winching cable around a grooved drum controlled by a thermostat and timer.

Auto Curtain 506S

The model 506S version uses a sprocket and chain drive (instead of drum) turning a pipe that runs the length of the building pulling the curtain or door drop cords directly around the pipe eliminating the need for cable (operates same as 506)

SP-2 Control

The SP-2 reads the static pressure in the room and adjusts any three wire drive unit until it reaches your preset requirement. With an adjustable time delay, manual adjustment and a high and low pressure alarm, this static pressure control is as complete as they get.

Auto-Air Actuator
The Auto-Air Actuator gives precise control of automated air inlets or baffles. This powerful unit features 24" of travel and 700 pound lift capacity. The actuators internal potentiometer communicates with any Airstream control through the PF-6 inlet positioning module. The PF-6 and Auto-Air Actuator work together to adjust to the correct air inlet position for all stages of ventilation providingoptimum environmental control.

Quick Disconnect Cords

Hardware Kits
Heavy-duty galvanized steel construction features sealed needle bearing pulleys, anti-wrap design and plated fasteners for ease of installation.

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.

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.

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

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

Heavy-duty Construction

Solid construction and rust resistant materials make the sprocket controller a reliable workhorse year after year.

Polyethylene Pulley Covers

Polyethylene pulley covers help stop the elements from entering through the area around the pulleys.

TC4-NV2S Control

This microprocessor based control was designed specifically for curtain machines. It can accommodate one curtain machine, one heater and one mister for example. With an easy to use digital display it can be programmed with automatic growth curves and interfaces with your PC when used with an interface. Up to four sensors can be used to average the temperature of larger rooms. Adjustable open and close times help make it the most precise curtain control for the money. It can be used with all curtain machines that do not have internal timers.
