The Filter Fan Plus model 01873.0-30 is a 223 mm × 223 mm airflow-in fan for cooling electrical enclosures, operating at 230 V AC, 50 Hz. It consumes 64 W of power and delivers a cooling airflow of 159.5 cfm (inlet) and 179.5 cfm (outlet), with an average noise emission of 64 dB(A). The unit features a plastic housing and hood certified to UL94 V-0, an aluminum axial fan with a service life exceeding 56,000 hours, and is rated IP54 and UL/NEMA Type 12. Mounting is via a frame with twist locks, requiring a 223 mm × 223 mm cut-out. It connects via a 3-pole clamp for 2.5 mm² conductors and operates from -13 °F to 149 °F with ≤90 % relative humidity. Accessories include a replacement filter mat (FM 086) and optional hose-proof hood (FFH 086).
Filter fans are used to provide "cooling" by forced air-circulation in enclosures and cabinets containing eletrical/electronic
The Filter Fan Plus series encompasses a new air-flap technology on the air outlet side, thereby reaching an unparalleled high degree of airflow. A unique ratchet mechanism is used for easy installation. It provides safe and secure mounting while guaranteeing a tight seal. Depending on the requirements, there are two optional systems available – the FPI or the FPO system (FPI = "in", FPO = "out"). The FPI system is the more commonly known installation system, where a filter fan located in the lower part of the enclosure draws cleaner, cooler air into the enclosure (airflow direction "In"). This system consists of a filter fan and exhaust filter. On opposite, with the newer FPO system, the filter fan will be located in the upper area of the enclosure to draw warmer air out of the enclosure (airflow direction "Out"). The FPO system consists of an intake filter and exhaust filter fan. The Filter Fan Plus series has been designed for indoor use.
