It is designed to accept the existing OEM fan blade and lock nut from the original installation

food-grade materials

allowing the suction pressure to be raised during lower-load periods

Frequent tripping usually indicates restricted venting airflow

The 50VA rating of the AT150A1007 provides more current capacity

Field Controls 602602001 Pressure Switch 319825-402 It is designed to acceptThe Field Controls 602602001 Pressure Switch is a high precision sensing component specifically engineered for use with PVG 100 power venters. As a critical safety interlock, this SPST pressure switch monitors the negative pressure generated by the blower to ensure proper combustion air volume before allowing the burner to fire. Designed for induced draft systems, it features an 8" WC set point with built in differential hysteresis to prevent rapid
