LEIPOLE FK9923.300 Exit Filter | 204 x 204mm | IP54 Passive Outlet

The FK9923.300 is the matching exit (outlet) filter for the FK9923 fan family. It has no motor: it provides a filtered, IP54-rated exhaust path for the air displaced by the companion filter fan, so the fan works against minimal back-pressure and the enclosure stays protected against dust ingress.

Housing dimensions match the FK9923 fans for a uniform panel layout, and the front cover opens for quick filter mat replacement.

The FK9923.300 is a passive IP54 exit filter that completes the airflow path for FK9923 enclosure filter fans in mid-size control cabinets, switchgear and automation enclosures. Mount it high on the opposite side of the enclosure from the intake fan so warm air leaves through a filtered outlet.

Because it contains no motor, the FK9923.300 works with every voltage version of its companion fans — 230V/50 Hz installations in Europe and Asia as well as 115V/60 Hz panels in North America and 24V DC solar and telecom cabinets.

Durable in Dusty Conditions

We operate in a high-dust environment, and these fan filters are holding up beautifully. The IP rating is legitimate, and the motors show no signs of slowing.

Rock Solid Connectivity

These terminal blocks have significantly reduced our assembly time. The vibration resistance is impressive, and the wiring remains secure even in high-stress environments. Excellent build quality.

Superior Thermal Control

The climate solution we integrated into our outdoor cabinets has been flawless. It maintains a steady temperature even during summer peaks. Highly recommend for sensitive electronics.

Quiet and Efficient

We replaced our old cabinet fans with Leipole units. The airflow-to-noise ratio is the best we’ve found. Easy to install and the filter changes are a breeze.

Precise Calibration

Finally, a thermostat that is easy to set and stays accurate. We’ve seen a noticeable decrease in energy waste since switching to these for our enclosure cooling.

Industrial Grade Reliability

These connectors handle high-current loads without breaking a sweat. The housing is rugged, and the snap-fit is very satisfying. Perfect for our modular panel builds.
