Rittal 3294100 Open-Celled Polyurethane Foam Filter Mat

Rittal 3294100 Open-Celled Polyurethane Foam Filter Mat

The Rittal 3294100 Open-Celled Polyurethane Foam Filter Mat is engineered for use on enclosure ventilation openings, fan units, and filter fan housings that are exposed to high levels of ambient dust. By trapping airborne particulate before it reaches sensitive components, this filter mat makes routine cleaning of enclosure equipment simpler and helps protect internal electrical and electronic devices from contamination. Constructed from open-celled polyurethane foam, the mat is temperature-resistant across a wide range, from -40C to +80C, making it suitable for demanding industrial, commercial, and outdoor-adjacent enclosure environments. Each package contains 3 filter mats, giving maintenance teams convenient on-hand replacement stock so filtration can be refreshed as soon as it is needed. Because filter performance declines as dust accumulates, Rittal recommends changing the mat on a regular basis, with the exact interval depending on the level of contamination at the installation site.

Key Features

• Durable Foam Construction: Made from open-celled polyurethane foam that provides effective, consistent airflow-through dust filtration for enclosure ventilation points.
• Wide Temperature Range: Temperature-resistant from -40C to +80C, supporting reliable performance in both cold and heat-exposed enclosure locations.
• High-Dust Environment Protection: Specifically recommended for installations with high dust exposure, helping shield enclosure interiors and mounted equipment from particulate buildup.
• Simplified Equipment Cleaning: Reduces the amount of dust that reaches internal components, which in turn simplifies and reduces the frequency of enclosure cleaning.
• Replaceable, Maintenance-Friendly Design: Intended to be changed on a regular schedule, with replacement frequency adjusted to the level of site contamination for consistent filtration performance.
• Convenient Multi-Pack Quantity: Supplied 3 pieces per packaging unit, so facilities can keep spares on hand and swap in a fresh mat without delay.
• Lightweight Packaging Unit: Each packaging unit is lightweight, simplifying storage, handling, and stocking of replacement filter mats.
