Filter Rittal SK 3285.920 — air filter mat, 599×320 mm, thickness 8 mm, black, pack of 3

Rittal SK 3285.920 is a replacement air filter mat designed for ventilation units and enclosures. The black filter media with a plastic frame measures 599 × 320 mm with an 8 mm thickness and is supplied as a pack of three. It collects dust and particulates to help protect fans, electronics and internal components inside cabinets and cooling systems.

Advantages

The filter mat offers simple installation in compatible filter holders and improves maintenance by trapping dust before it reaches fans and sensitive electronics. Supplied in a pack of three, it allows for scheduled replacements to maintain airflow and filtration performance.

Suitable for

• Ventilation units and extractor fans in electrical enclosures
• Cabinets and server racks requiring dust filtration
• Cooling systems and fan assemblies where a replaceable filter mat is needed

When it may not be suitable

This filter mat is intended for trapping general dust and particulates; it is not designed for filtering hazardous gases, chemical vapors or very fine aerosolized contaminants. It may not be suitable where HEPA-level or molecular filtration is required.

Key specifications

• Dimensions: 599 × 320 mm
• Thickness: 8 mm
• Color: black
• Frame material: plastic
• Package quantity: 3 filter mats per pack

How to use

Insert the filter mat into the compatible filter holder or frame of the ventilation unit or enclosure, ensuring a snug fit against the housing to prevent bypass of unfiltered air. Replace the mat at regular intervals based on the contamination level in the environment; more frequent replacement is recommended in dusty conditions. Dispose of used mats according to local waste regulations.

What to consider before purchase

• Verify compatibility of the 599 × 320 mm size and 8 mm thickness with your ventilation unit or filter holder.
• Assess environmental contamination to determine replacement frequency.
• Confirm that particulate filtration is sufficient for your application and that no specialized chemical or HEPA filtration is required.

Usage recommendations

For dusty environments, use the filter mats to simplify cleaning and protect internal components; replace them at regular intervals depending on contamination to maintain effective airflow and protection.
