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.

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.

The plug-in integrated dehumidistat automatically detects excess humidity in a space and activates the fan for control of excess moisture. The sensitivity is adjustable from 50% RH to 80% RH and also includes a built in 15 minute time delay.

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.

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.

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.

Time delay switches save energy by automatically turning off equipment. They may be used with SP and CSP fans or fan and light combinations for extended operating time of fan. Time delay switches act in the same manner as a standard switch, however, there is a delay of 10 to 60 minutes after the fan has been turned off.

The Minimum Ventilation Control Switch monitors the operation of the fan to make sure that the space is receiving the correct amount of ventilation per ASHRAE 62.2.

Brick vents provide a permanent means of ventilation for crawl spaces, hung ceilings, incinerator rooms, chimney flues, foundations, pipe spaces and corridors. Extruded construction provides a quality finished appearance. A high water stop at the rear and deep overlapping blades with storm stops provide maximum resistance to rain and weather.

• Anodized aluminum construction
• Built in aluminum mesh insect screen

Washable aluminum mesh filters reduce the accumulation of airborne dirt on fan wheels and motors, extending the life of the fan. For use on models SP-A50-A390, B50-B200 with Designer Grille option.

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.

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.
