Pressure-Timer Switch

Fan Control - Pressure-Timer Switch by American Aldes

American ALDES Pressure-Timer Switch - P/N 99 058 dryer booster fan switch. It recognizes dryer operation and activates a booster fan from an independent electrical circuit. This eliminates connections through the dryer circuit which may void the manufacturers’ warranty as well as manual systems which require the attention of the operator or costly current/temperature sensing systems.

The electrical to the booster fan is connected in series through a normally open terminal on the switch. A pressure tap is connected to a nipple on the side of the switch. When the dryer begins operation, positive pressure in the duct causes the switch diaphragm to expand closing the circuit to the booster fan. An integral delay on- make timer in the switch will cycle the fan on for intervals of approximately 10 minutes. This will continue until the dryer has stopped and the timer delay period has lapsed. Drying cycles, the booster fan, the delay timer and the pressure switch are not adversely affected by the starting/ stopping intervals.
