FKL5521 Ultra-Thin Enclosure Fan Filter is the most compact model in the FKL55 series, purpose-built for space-constrained electrical cabinets.
The ultra-thin filter is equipped with a premium sealing strip along its edges, effectively preventing dust and moisture from entering the control cabinet through the openings. The surface louver features an arched structure that further blocks ingress. A non-woven fiber filtration pad prevents dust particles larger than 10 microns. With a louver protrusion of only 4-6mm, it greatly enhances aesthetic appeal. No screws are required for installation — simply snap it into the pre-cut opening.
