Filter Rittal SK 3286.120, aluminium housing, single unit

Rittal SK 3286.120 is a metal filter in an aluminium housing designed for ventilation and protection of electrical cabinets and industrial enclosures. Supplied as a single unit, the aluminium housing offers a lightweight, corrosion-resistant solution for air filtration where robust metal construction and easy cleaning are required. The filter is intended for use in cabinet ventilation systems to help prevent ingress of larger particles while allowing required airflow.

Advantages

The aluminium housing provides good resistance to corrosion and a favourable strength-to-weight ratio, making the filter easy to handle and install. As a metal filter it tolerates washable maintenance; accumulated dust and oily deposits adhere to the metal surface and can be removed with water or grease-dissolving detergents. The single-unit supply simplifies inventory and replacement planning for installations that require individual filters.

Suitable for

• Ventilation and air filtration of electrical cabinets and control enclosures
• Industrial environments with moderate dust or grease-containing aerosols
• Applications requiring corrosion-resistant, lightweight filter housings

When it may not be suitable

This aluminium metal filter is not intended for high-efficiency particulate air (HEPA) level filtration or for capturing very fine dust and submicron particles; it is designed mainly to retain larger particles and protect cabinet components. It may also be unsuitable for environments where a sealed filter assembly with integrated seals and gaskets is required to meet specific ingress protection (IP) ratings.

Key specifications

• Housing material: aluminium
• Filter type: metal washable filter
• Supply quantity: single unit (1 pc)
• Typical applications: enclosure and cabinet ventilation
• Colour: aluminium (natural metal finish)

How to use

Install the filter into the designated filter slot or mounting frame of the enclosure ventilation panel according to the enclosure manufacturer's instructions. Ensure correct orientation and secure fastening to avoid gaps that could allow unfiltered air to bypass the element. Regularly inspect the filter for accumulated dust and deposits; clean by rinsing with water or using a grease-dissolving detergent when oily residues are present. Allow the filter to dry completely before reinstalling to prevent moisture entering the enclosure.

What to consider before purchase

• Verify physical dimensions and mounting compatibility with your cabinet or ventilation panel
• Assess whether metal filtration performance meets your particulate retention requirements
• Consider cleaning intervals and maintenance access in your installation
• Confirm environmental conditions (temperature, humidity, presence of corrosive agents)

Usage recommendations

For dusty or oily ambient air, use washable metal filters and plan periodic cleaning. Rinse with water or use a grease-dissolving detergent for oily deposits, then allow complete drying before reinsertion. Where finer filtration is required, combine the metal filter with downstream finer filter stages as needed.
