Filter Rittal SK 3238.025 — replacement pleated filter, white, pack of 5

Rittal SK 3238.025 is a pack of five white pleated replacement filters designed for use with compatible filter fans and air outlet units in electrical enclosures. The pleated filter media increases volumetric airflow compared with conventional chopped-fibre mats, improving cooling-unit performance while reducing energy consumption. Enhanced filtration captures more dust, contributing to cleaner internal environments and longer service intervals for ventilation and cooling systems.

Advantages

The pleated construction provides a larger effective surface area, enabling higher airflow and improved heat dissipation without increasing fan power. Better filtration properties reduce dust accumulation inside enclosures and on components, which helps maintain IP-protection performance and reduces the frequency of maintenance. Supplied as a pack of five, the filters simplify scheduled replacements and spare-part management.

Suitable for

• Filter fans and air outlet units in electrical enclosures
• Industrial control cabinets and switchgear ventilation systems
• Cooling and air-conditioning units requiring particulate filtration
• Preventive maintenance and periodic filter replacement programs

When it may not be suitable

This pleated replacement filter is intended for particulate filtration and ventilation performance improvement; it is not designed for chemical filtration, odor removal, or capture of gaseous contaminants. It may not be suitable for environments with unusually high humidity, oil mist, or corrosive aerosols unless the system is specified for such conditions. Verify compatibility with the specific filter-fan or outlet unit model before installation.

Key specifications

• Filter type: pleated particulate filter
• Color: white
• Pack contents: 5 replacement filters
• Primary function: improve airflow and capture dust in ventilation paths
• Typical application: electrical enclosures, control cabinets, ventilation units

How to use

Remove the used filter from the compatible filter fan or air outlet unit following the equipment manufacturer's instructions. Inspect the filter housing for accumulated debris and clean the area if necessary. Install the new pleated filter ensuring correct orientation and secure fit to maintain sealing and airflow performance. Replace at regular maintenance intervals or sooner if visual inspection shows heavy contamination.

What to consider before purchase

• Confirm physical compatibility with your filter-fan or air outlet unit model
• Assess typical contamination levels and replacement frequency required for your environment
• Ensure pleated particulate filtration meets your requirements (not suitable for gas/chemical filtration)
• Check maintenance procedures and access for replacement in installed locations

Usage recommendations

Use the Rittal SK 3238.025 filters as part of a scheduled maintenance plan: inspect filters visually every maintenance cycle, replace when visibly loaded or according to the equipment manufacturer's recommended interval, and store spare filters in a dry, dust-free environment to preserve performance.
