The RFP 018 roof filter fan is designed to expel warm air from enclosures, ensuring component cooling through forced air circulation. The 01861.0-02 variant operates at 120 V, 60 Hz, consuming 85 W and providing 338.4 cfm of cooling airflow with a noise level of 67 dB(A). It features an aluminum fan body with a plastic rotor, plastic housing rated UL94 V-0 and UV resistant per UL746C (f1), and a G3 filter mat meeting ISO 16890 with 57% initial gravimetric arrestance. Operating and storage temperatures range from -13 °F to 158 °F. The unit has a height of 7.1 in, installation depth of 4.2 in, and weighs 91.7 oz, with a 3-pole clamp connection rated for 2.5 mm² and a maximum torque of 0.8 Nm. Protection class is I and protection type is IP32. The fan requires paired use with an inlet filter or inlet filter fan for pressure compensation.
Roof filter fans and roof exhaust filters are used in enclosures from which warm air must be diverted due to increased heat development. The ready-to-connect and low-noise roof filter fan is used to expel warm air from within the enclosure. Alternatively, the roof exhaust filter provides passive ventilation. The RFP 018 series comes in two versions: one utilizes four small axial fans, improving reliability and maintaining continuous operations even if one of the fans should fail; the second uses a larger single high capacity fan.
