Johnson Controls P66BAB-1 Dual Fan Speed Control 190/250 PSI 5' CAP

The Johnson Controls P66BAB-1 is a controlling device for two fans that is used to enhance the flow rate and save energy in a communication air conditioning system. It is 5 feet long and is designed to operate at voltages appropriate for 24 VAC circuits. It can take pressure settings of between 190-250 PSI. This control unit employs the pressure changes of the HVAC system to control fan speeds. It reduces power consumption and provides the best results 1by adjusting the air flow rate. The is common in rooftop HVAC systems and air handling units to control fans according to the need for regulating temperature and ventilation. It increases equipment run time, reduces operating costs, and enhances system performance by optimizing fan control.
