Faltenfilter Rittal SK 3182.125 for enclosure air filters T 212.5 21 mm, pack of 5

Rittal SK 3182.125 Faltenfilter is a pleated replacement filter element designed for ventilation openings in electrical enclosures and control cabinets. Intended for use with filters conforming to the T 212.5 format and 21 mm thickness, this pack of five filter elements helps reduce ingress of dust and particulate matter while maintaining airflow through fan and filter units. The product is suitable for industrial housings where regular filter replacement is required to preserve internal cleanliness and protect sensitive components.

Advantages

The pleated construction increases effective filtration area within a compact 21 mm thickness to capture dust and particles while allowing adequate airflow. Supplied as a pack of five, the set reduces downtime by providing replacements on hand for routine maintenance. The design is compatible with enclosure ventilation systems that use T 212.5 filter frames, enabling straightforward, repeatable filter changes without modifying cabinet openings.

Suitable for

• Control cabinets and electrical enclosures requiring particulate filtration
• Industrial housings with T 212.5 filter frame and 21 mm filter depth
• Maintenance schedules that call for periodic filter replacement
• Applications where protection from dust prolongs equipment life

When it may not be suitable

This pleated filter is intended for particulate and dust filtration and may not be suitable where high-efficiency removal of very fine aerosols, gases, or chemical vapors is required. It is also not appropriate for installations that demand a different filter format, thickness or frame size than T 212.5 and 21 mm.

Key specifications

• Filter type: pleated replacement element
• Compatible format: T 212.5
• Thickness/depth: 21 mm
• Pack quantity: 5 filter elements
• Application: enclosure ventilation and dust filtration

How to use

Turn off fans or ventilation units and isolate the enclosure from power before replacing filters. Remove the filter frame or access cover for the filter location, extract the spent 21 mm pleated element and install the new filter ensuring correct orientation and a secure seat in the frame. Reattach the frame or cover and resume ventilation. Inspect filters regularly and replace according to site-specific contamination levels or the maintenance schedule.

What to consider before purchase

• Verify that your enclosure ventilation system uses the T 212.5 filter format and accepts 21 mm thick elements
• Assess the expected dust load and replacement frequency to determine pack size sufficiency
• Confirm that particulate filtration meets your requirements; for gas or chemical filtration choose a different media

Usage recommendations

For consistent protection of internal components, establish a filter inspection and replacement interval based on operating environment; in dusty or industrial conditions check filters more frequently. Keep spare filter elements on hand to avoid prolonged exposure of cabinet interiors to unfiltered air during maintenance.
