Filter Rittal SK 3285.860 — aluminium housing, replacement filter for SK enclosures

Rittal SK 3285.860 is an aluminium-housed replacement filter intended for use in Rittal SK enclosure systems. Supplied as a single unit, this lightweight 100 g filter provides ventilation and dust protection for electrical cabinets and control panels where an aluminium filter element is specified. The component is designed for periodic maintenance or as a spare part to preserve airflow while preventing ingress of larger particles into SK-series housings.

Advantages

The aluminium construction offers corrosion resistance and dimensional stability while remaining lightweight for easy handling and installation. As a washable metal filter, it can be cleaned and reused, reducing waste and lowering maintenance costs compared with disposable media. The single-piece design matches the form factor of Rittal SK ventilation openings, ensuring straightforward replacement without modification.

Suitable for

• Replacement of aluminium filter elements in Rittal SK enclosure ventilation systems
• Ventilation and dust protection for electrical cabinets and control panels
• Maintenance and spare-part stocking for industrial enclosures using metal filters

When it may not be suitable

This aluminium filter is intended to stop larger particles and provide basic dust protection; it is not a fine-particle HEPA or electrostatic filter and should not be relied on where high-efficiency particulate removal is required. It may also be inappropriate in applications that require non-metallic or specific chemical-resistant filter media not matched by aluminium.

Key specifications

• Housing material: aluminium
• Filter material: aluminium metal element (washable)
• Quantity: 1 piece
• Weight (approx.): 100 g
• Intended application: ventilation/dust protection for SK-series enclosures

How to use

Turn off electrical equipment and de-energize the enclosure according to site safety procedures before replacing the filter. Remove the existing filter from the SK ventilation opening and insert the Rittal SK 3285.860 in the correct orientation so that it seats securely in the housing. After installation, restore power and verify airflow is unobstructed. For cleaning, remove the filter and wash with water or a grease-dissolving detergent if oily residues are present; allow to dry completely before reinstalling.

What to consider before purchase

• Verify compatibility with your specific Rittal SK enclosure model and ventilation aperture dimensions
• Assess whether a washable aluminium filter meets your particulate-efficiency and chemical-resistance requirements
• Consider environmental conditions (dusty or oily ambient air) and the recommended washing maintenance

Usage recommendations

For environments with dusty or oily air, use washable metal filters and establish a regular cleaning schedule. If condensation of air or steam occurs, particles will adhere to the metal and can be removed effectively with water or a suitable grease-dissolving detergent; ensure the filter is fully dry before reinstallation.
