The felt filter pads for plastic filter ventilators for switchboxes (84090) and plastic outlet filters for plastic filter ventilators (84090-01) ensure reliable filtration of the intake air and protect the components inside the switchbox from dust and dirt. They ensure even air flow, thereby helping to maintain the long-term performance of the switchbox ventilation system. The precise fit enables rapid replacement and easy maintenance of the filter system.

These felt filter pads are meant as replacement filters for the plastic filter ventilators for switchboxes (84090) and the plastic outlet filters for filter ventilators (84090-01). The selection depends on the size and type of ventilator used. The filter pad should be checked regularly for dirt to ensure optimum cooling performance and replaced if the air flow rate is reduced. Maintenance intervals depend on the environmental conditions and the application area.
