Dust filter Rittal SK 3237.020, anthracite, pack of 2

The Rittal SK 3237.020 dust filter in anthracite is supplied as a pack of two and is intended for use with compatible Rittal enclosures and ventilation openings. This lightweight accessory provides basic particulate protection by reducing ingress of dust into electrical and industrial cabinets, helping maintain component cleanliness and airflow while preserving a neat installation appearance.

Advantages

The pack of two filters offers an easy-to-install solution for routine dust control in cabinet ventilation paths. The anthracite finish matches common enclosure colours and helps maintain a discreet visual profile. The product is designed for straightforward replacement and does not require modification of the enclosure, making it suitable for maintenance cycles and environments where simple particulate filtration is sufficient.

Suitable for

• Industrial electrical enclosures with compatible mounting cut-outs
• Control cabinets and switchgear requiring basic dust reduction
• Applications where a neat, colour-matched finish is desired
• Maintenance tasks that call for quick filter replacement

When it may not be suitable

This dust filter provides basic particulate protection and is not designed for high-efficiency filtration of very fine particles, gases, or corrosive aerosols. It is not a substitute for sealed, high-IP-rated ventilation solutions where full environmental protection against moisture, liquid ingress or aggressive contaminants is required.

Key specifications

• Pack quantity: 2 pieces
• Colour: anthracite
• Intended use: dust filtration for ventilation openings and mounting cut-outs
• Compatibility: for use with compatible Rittal enclosures and fan-and-filter outlets
• Material characteristics: lightweight construction suitable for simple particulate control

How to use

Fit the filter into the compatible ventilation opening or mounting cut-out according to the enclosure manufacturer's instructions. For applications where a higher protection category is required, a blanking cover can be used in place of a filter mat to close mounting cut-outs without welding or metal machining. Replace the filters as part of regular maintenance or when dust accumulation noticeably restricts airflow.

What to consider before purchase

• Confirm mechanical compatibility with the enclosure mounting cut-out and fan-or-filter unit
• Determine whether basic dust filtration is sufficient or if a higher-efficiency or sealed solution is needed
• Consider the operating environment (amount and type of particulate matter) and maintenance intervals

Usage recommendations

Install filters during routine maintenance and inspect periodically for dust build-up; where higher ingress protection is required, consider using a blanking cover or a sealed fan-and-filter solution to achieve the necessary protection class.
