The STEGO Filter Fan Plus FPO 018 (Part No. 01881.2-00) is a high-performance enclosure cooling fan engineered to deliver optimal forced convection and thermal protection for electrical enclosures, control panels, and outdoor automation cabinets.

Operating on the innovative FPO (Outflow) system, the quạt is mounted in the upper section of the enclosure to actively pull hot air out of the cabinet, working in tandem with an intake filter located at the bottom. The advanced physical design features gravity flaps instead of a traditional filter mat on the exhaust side, significantly reducing air resistance and increasing air volume output up to 110 m³/h while maintaining an IP54 protection rating against dust and moisture. Constructed from UV-resistant, flame-retardant ABS plastic according to UL94 V-0, the Stego 01881.2-00 incorporates a patented tool-less 4-corner ratchet mount for fast, secure installation into a standard 176x176mm cut-out without screws.
