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.

For natural gravity or positive pressure systems, model GRSF 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.

• All aluminum exterior for corrosion-resistant construction
• Integral birdscreen to prevent entry of birds and small objects
• 19 x 19 inch base with built-in flashing flange and prepunched mounting holes for quick and easy installations without a roof curb

Speed controls are used for manual adjustment of the fan’s performance (for final system balancing) or to control the fan’s 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.

Adjustable for temperature ranges between 30ºF to 110ºF (-1ºC to 43ºC), 120V, 16 amp

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

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

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.

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

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.

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.

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

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.

Pitched roof cap discharge accessory constructed of steel with black enamel finish. Includes integral flashing flash, built-in birdscreen and damper.

Transformers are available for applications requiring voltage reduction. Selection is based on motor amperage. Rated for 115 to 230/277V, 6.5A.

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.

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.

• 19 x 19 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

GPI roof curbs are designed for flat, insulated or non-insulated roof decks. Constructed of 18 gauge galvanized steel and fully formed on three sides with a single, fully welded seam.

• Designed to fit 19" roof curb cap
• 2-inch mounting flange
• Rigid, fiberglass insulation
• Welded, straight-sided construction

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.

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.
