Computer cooling part Rittal 3171.100, fiber air filter panel for SK 3239, 173×173×17 mm, grey

Rittal 3171.100 is a fiber air filter panel designed as a replacement cooling accessory for Rittal SK 3239 enclosures. The panel measures 173 × 173 × 17 mm and is finished in grey. Manufactured from a chopped-fibre mat with a progressive structure, this air inlet filter supports enclosure ventilation by removing dust from incoming air while maintaining designed airflow conditions and protecting internal electronics. It is temperature-resistant up to 100°C and meets self-extinguishing category F1 to DIN 53 438.

Advantages

The progressive fibre structure provides an open side facing dust-laden air and a closed side toward clean air, allowing reliable filtration of particles from approximately 10 µm and larger. The material's temperature resistance to 100°C and F1 self-extinguishing rating increase operational safety in confined electrical enclosures. The compact dimensions (173×173×17 mm) make it a direct fit for compatible ventilation assemblies, simplifying replacement and maintenance.

Suitable for

• Rittal SK 3239 enclosure ventilation and air-inlet protection
• Industrial control cabinets and electrical enclosures requiring dust filtration
• Applications where compact, temperature-resistant inlet filters are needed

Key specifications

• Material: chopped-fibre mat with progressive structure
• Dimensions: 173 × 173 × 17 mm
• Color: grey
• Filtration capability: effective from particle size ≈ 10 µm
• Temperature resistance: up to 100°C
• Flammability: self-extinguishing category F1 (DIN 53 438)
• Airflow orientation: open structure on dust-laden air side, closed structure on clean-air side

How to use

Install the fiber air filter panel into the designated inlet frame or filter holder on the Rittal SK 3239 enclosure, ensuring the open-structured side faces the incoming dust-laden air and the closed side faces the enclosure interior. Verify the panel fits securely without gaps that could bypass filtration. Replace the filter according to site maintenance intervals or earlier if visible dust loading reduces airflow. Dispose of used filters following local regulations for industrial waste.

Recommendations

For reliable ventilation and protection, inspect the filter periodically and replace when heavily soiled or when airflow is noticeably reduced. Avoid exposing the filter to direct flame sources despite its F1 rating, and ensure compatibility with the enclosure's mounting frame before installation.
