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.

Rittal 3294100 – Frequently Asked Questions

1) How many filter mats come in a pack of the Rittal 3294100?
The Rittal 3294100 ships 3 filter mats per packaging unit, so a maintenance crew has spares on the shelf and can swap a loaded mat out right away instead of waiting on a reorder.
2) Can a polyurethane foam enclosure filter mat handle an outdoor cabinet that sees freezing winters and hot summers?
Temperature resistance on the Rittal 3294100 foam mat runs from -40C to +80C, which covers cold outdoor cabinets and heat-soaked panel locations alike. It is an air filtration element, not a weather seal, so the enclosure and fan housing still have to provide the environmental protection.
3) Where does the 3294100 filter mat actually get installed on an enclosure?
It goes at the air inlet points: enclosure ventilation openings, fan units, and filter fan housings. The mat sits in the airflow path and catches airborne dust before it reaches the devices mounted inside the cabinet.
4) How often should enclosure filter mats be changed in a dusty plant?
There is no fixed interval. Filtration performance drops as the foam loads with dust, so Rittal's guidance is to change the mat on a regular schedule set by how contaminated the site is. A machine shop or mill inlet will want far shorter intervals than a clean control room.
5) Will a foam filter mat keep dust out of switchgear and control panels?
That is exactly its job. By trapping particulate at the ventilation opening, the 3294100 reduces how much dust settles on contactors, drives, PLCs and terminal blocks inside the cabinet, which cuts down both the frequency and the effort of interior cleaning. It is a particulate filter only, so it does nothing for oil mist, corrosive gas, or water ingress.
6) What is the Rittal 3294100 made of, and can it be cleaned instead of replaced?
The element is open-celled polyurethane foam. It is sold as a replaceable consumable, supplied in threes so a loaded mat gets swapped for a fresh one rather than nursed along. Treat it as a change-out item on your PM schedule.
7) What is the Rittal part number to order for this foam filter mat?
Order Rittal 3294100. That is the manufacturer part number for the open-celled polyurethane foam filter mat supplied three per pack.
