Constant Pressure Fan Controller ZPR-1

Fan Control - ZPR-1 by American Aldes

American ALDES ZPR-1 - P/N 28 555 constant pressure fan controller. The ALDES ZPR-1 Zone Pressure Regulator is a compact, TRIAC based fan & motor control designed for the HVAC, electronics and industrial controls markets. The ZPR- 1 can automatically control most single phase AC fans and motors used in exhaust ventilators, duct fans and blowers. The ZPR- 1 regulates motor speed from a pressure transducer or flow transducer. Automatic voltage and frequency detection, current ratings up to 7.5A. The 4” x 4” job box mount, make this microprocessor based design extremely flexible and economical. Benefits of using ZPR-1 include acoustical noise reduction, pressure or flow regulation, greater system reliability, increased fan life, improved safety and energy savings.
