FOCUS ON EC FAN ONLY
PBM FOCUS ON EC FAN ONLY. Certificate: CE,UL,ROHS; Supply Ability: 100,000 pcs per year; MOQ: 1~100 pcs based on EXW price; 100 pcs above based on FOB price.
190mm DC Backward Curved Centrifugal Fans made especially for VAV, a damper control system for Variable-Air-Volume air handling system in Ventilation and Purification is the PB3N190B24-TZ1. The PB3N190B24-TZ1 is especially well-suited for situations with high downstream resistance (usually higher than 50Pa) in VAV terminal units because of its high static pressure output of 950Pa. It is the perfect solution to the problem of effective linkage control between fans and valve actuators in VAV system terminal units because it guarantees steady supply air pressure and volume output on the fan side during valve actuator opening adjustments. For a variety of VAV system terminal devices, it offers dependable, compact, and high static pressure fan power.
High-quality EC/DC fans and intelligent airflow solutions that fully satisfy the safety and dependability requirements of international standards like AHRI and ASHRAE for VAV system terminal equipment, support VAV terminal units, parallel fan enclosures, and other products are PPM's main areas of focus. Customized fan inlet and outlet air direction designs based on the VAV terminal enclosure construction are supported, as are OEM customization services.
