Automatic pressure switch allows for fully automatic operation of dryer booster fan. Fan runs for 10 minutes when positive pressure is sensed in the duct line then shuts off and turns on again as needed.

This P70 Series of controls employs a set of switch contacts that are opened and closed by the movement of pressure actuated bellows. The load-carrying contacts provide direct control of AC motors within the control rating. Note the electrical rating chart for specific models. These controls are available with either close high-open low, open high-close low, or SPDT contact action.
