The roof filter fan RFP 018, model 01861.0-00, is a 230 V, 50 Hz axial fan designed for exhausting warm air from electrical enclosures with integrated pressure compensation. It has an aluminum fan body and plastic rotor, a G3 plastic fiber filter mat rated by ISO 16890 with 57 % initial gravimetric arrestance, and operates within a temperature range of -13 °F to 158 °F. The unit produces 294.3 cfm of cooling airflow at 67 dB(A) and has a mounting cut-out of 246 x 246 in. The casing is UL94 V-0 rated light gray plastic with UV resistance per UL746C (f1), and the connection is a 3-pole clamp rated for 2.5 mm² max. with a maximum torque of 0.8 Nm. Service life exceeds 50,000 hours. Operation requires pairing 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.
