The article SK 3172100 from Rittal is a replacement filter mat for filter fans, specifically designed for use in Rittal filter fan models from the SK 3240… and SK 3241… series. The filter mat serves air purification in enclosures and similar technical housings by reliably filtering particles from 10 µm in size from the incoming air. It is made of chemical fiber in the form of a nonwoven mat with a progressive structure, ensuring efficient filtration while maintaining low air resistance.

Applications

The filter mat is intended for use in industrial enclosures and electronic housings where continuous air purification is required to remove dust and particles from the internal air. It is used in combination with filter fans that ensure controlled supply of clean air into the enclosure. The filter mat is not suitable for EMI filter fans, as these require specific electrical shielding properties that are incompatible with this filter mat.

Functions and Features in Detail

The filter mat consists of a nonwoven mat with an open structure on the dusty air side and a closed structure on the clean air side. This design enables effective particle separation, with the open side capturing dust and the closed side directing purified air into the enclosure. Filtration is reliably effective for nearly all dust types from a particle size of 10 µm. The filter class corresponds to G3 according to DIN EN 779 and ISO Coarse 50 % according to DIN EN ISO 16890, representing medium filtration performance suitable for general industrial applications.

Technology Explained Simply

The chemical fiber used is heat-resistant up to 100 °C and self-extinguishing in class F1 according to DIN 53 438, ensuring high safety at elevated temperatures and in case of fire. The progressively structured mat ensures that larger particles are captured in the upper layers, while smaller particles are filtered deeper within the material. This extends the service life of the filter mat and ensures even loading.

Compatibility and Accessories

The filter mat is specifically designed for Rittal filter fan models SK 3240… and SK 3241…. It is used in conjunction with these fans to ensure air purification in the enclosure. The packaging unit contains 5 pieces, offering an economical and practical solution for operation. No information is available regarding additional compatible accessories or alternatives in the sources.

Installation and Mounting

The filter mat is inserted into the filter fan with the open structure facing the dusty air side. Mounting is done by simply placing it into the designated filter frame of the fan. Dimensions are 221 mm (width) × 221 mm (height) × 17 mm (depth), ensuring an exact fit for the specified fan models. No special installation instructions or tools are required.

cOperational Advantages

The filter mat provides reliable and low-maintenance air purification, extending the service life of electronic components in the enclosure. High heat resistance and self-extinguishing properties increase operational safety. The packaging unit of 5 pieces enables efficient maintenance and reduces downtime by allowing proactive replacement of filter mats.
