Dust filter Rittal SK 3240.020 — grey, pack of 2

The Rittal SK 3240.020 dust filter — grey, pack of 2 — is a vent filter element designed to reduce dust ingress into electrical and industrial enclosures. Supplied as two identical filter panels, it fits ventilation openings and mounting cutouts to protect internal electrical and electronic components from particulate contamination. The product is intended for use where controlled airflow and basic particulate filtration are required without modifying the enclosure structure.

Advantages

The filter offers straightforward protection against dust and airborne particles while maintaining airflow through enclosure ventilation points. Its grey colour provides a neutral, unobtrusive appearance when installed on cabinets. Supplied as a pack of two, it allows replacement or use on multiple ventilation openings and helps extend the service life of internal equipment by reducing contamination-related failures.

Suitable for

• Industrial control cabinets and electrical enclosures with compatible ventilation cutouts
• Protecting motors, power supplies and control electronics from dust
• Machine building and panel assemblies where simple particulate filtration is needed
• Maintenance kits or spare parts inventory for routine filter replacement

When it may not be suitable

This dust filter is designed for basic particulate exclusion and is not a solution for environments requiring HEPA-level filtration, explosion protection, or ingress protection against liquids. It will not provide thermal management beyond allowing existing ventilation to operate and is not a replacement for purpose-built sealed or climate-controlled enclosures.

Key specifications

• Colour: grey
• Pack quantity: 2 filter elements
• Application: ventilation dust filtration for enclosures
• Mounting: intended for mounting openings/cutouts on compatible cabinets
• Function: reduces particulate ingress while permitting airflow

How to use

Install the filter in the ventilation opening or mounting cutout designated for filter elements on the enclosure. Ensure the filter sits flush and is secured according to the enclosure's mounting method to avoid gaps. Replace filters periodically based on visible soiling or when airflow becomes noticeably restricted; having the spare element from the pack allows immediate replacement during routine maintenance. Follow normal safety procedures by de-energising equipment if required by the enclosure access policy before installation.

What to consider before purchase

• Confirm the filter dimensions and mounting compatibility with your enclosure ventilation or cutout
• Assess the level of particulate contamination in your environment to determine if basic dust filtration is sufficient
• Plan a replacement interval based on operating environment and airflow requirements

Usage recommendations

Inspect filters regularly and replace when visibly clogged or when ventilation performance drops. Use the two-piece pack to keep one filter as a spare for quick replacement during maintenance cycles. For environments with fine dust, oils, or high humidity, consider combining this filter with appropriate enclosure protection measures.
