Wall louvered discharge with anodized aluminum grille designed for exterior applications. Units feature built-in damper to eliminate backdrafts.

Motion detectors use a passive infrared motion detector to automatically turn the fan on when a change in motion is sensed. They have a viewing area of 180 degrees, however they must be placed in the line-of-sight. May be used with SP and CSP fans or fan/light combinations.

NEMA-1 rated disconnect switch provides positive electrical shutoff and safety. Disconnect switches are a recommended and necessary safety feature for every fan. Mounted directly on the fan, within sight and reach, disconnect switches provide the best protection against accidental startup during service or inspection.

Model MS-16 is a 1 Pole, single throw wall mount manual starter with pilot light. This starter supports up to 1/2 HP, 120 Volt, 1 Phase and includes a face plate.

Adjustable for temperature ranges between 30潞F to 110潞F (-1潞C to 43潞C), 120V, 16 amp

Speed controls are used for manual adjustment of the fan鈥檚 performance (for final system balancing) or to control the fan鈥檚 output in confined spaces, such as conference or meeting rooms. The fan can be adjusted to 60% of design airflow with a speed control. This reduction in airflow and fan speed is also accompanied by a reduction in noise level. Note: For use on direct drive fans with single phase, PSC or shaded pole motors.

Transformers are available for applications requiring voltage reduction. Selection is based on motor amperage. Rated for 115 to 230/277V, 8.6A.

For natural gravity or positive pressure systems, model GRS offers excellent performance and durability for intake or relief applications. Featuring an exceptional low silhouette design and rugged construction this model is both efficient and economical.

• 26 x 26 inch base with prepunched mounting holes for easy attachment to roof curb
• All aluminum exterior for corrosion-resistant construction
• Integral birdscreen to prevent entry of birds and small objects

Dehumidistats are available with models SP and CSP fans to ventilate humid spaces. The sensor automatically detects excess humidity and activates a ventilation fan for control of excess condensation. There are automatic, manual, or air cycle modes. This can replace a single pole switch for control of a ventilating fan.

When the temperature in the space rises above the set point of 50 F - 90 F the contacts close and the thermostat will signal the fan to come on in order to exhaust air from the space. Includes face mounted thermometer that displays room temperature.

Switches may be used on model SP and CSP fans to enable manual control of your fan or fan and light combination. Two single pole combination switch assembly rated for 120V, 15A. UL Listed.

Vibration isolation kit for suspended installation to minimize vibration, ensuring quiet operation.

The SP Ceiling Radiation damper protects fire rated ceilings and effectively blocks the spread of heat and flames through the building's ventilation system. This damper is UL Classified; rated at three to four hours fire resistance.

Switches may be used on model SP and CSP fans to enable manual control of your fan or fan and light combination. Single pole rocker switch assembly rated for 120-277V, 15A. UL Listed.

Hooded wall cap with rectangular duct connection designed for outside wall applications. Constructed of steel with black enamel finish, units feature built-in birdscreen and damper.

Switches may be used on model SP and CSP fans to enable manual control of your fan or fan and light combination. Single pole light combination switch assembly rated for 120V, 15A. UL Listed.
