The Filter Fan Plus model 01873.9-30 is a 223 x 223 mm air intake filter fan designed to cool enclosures by drawing in filtered outside air. It operates at 115 V, 60 Hz, consuming 81 W and providing a cooling airflow of 172.5 cfm with an average noise emission of 67 dB(A). The unit features a plastic housing and hood compliant with UL94 V-0, an aluminum axial fan with a metal rotor, and a G3 filter mat offering 57% initial gravimetric arrestance. It has an IP54 and UL NEMA Type 12 protection rating, a service life exceeding 56,000 hours, and operates within temperatures ranging from -13 °F to 149 °F. Mounting is facilitated by a frame with four rotary latches and a 5.8 in installation depth. The part includes a 3-pole clamp connector rated for 2.5 mm₂ and a maximum torque of 0.8 Nm.
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.
