Computer cooling system part Rittal 3172.105 — fiber panel 221×17×221 mm, air-cooled

Rittal 3172.105 — fiber panel 221 × 17 × 221 mm designed for air-cooled computer and industrial cooling systems. Manufactured from a chopped-fibre mat with a progressive structure, this panel serves as a structural and airflow-guiding component in server racks, control cabinets and other enclosures. It is temperature-resistant up to 100°C and classified as self-extinguishing F1 to DIN 53 438. The panel is engineered with an open-porosity side for dust-laden air and a closed-porosity side facing the clean-air side, providing reliable filtering of solid particles from approximately 10 µm and protecting downstream heat exchangers and electronic components.

Advantages

The progressive chopped-fibre construction delivers a gradient filtration effect that captures larger particles on the open side while finer particles are retained toward the closed side, improving overall dust-holding capacity and airflow stability. Temperature resistance to 100°C and F1 self-extinguishing classification ensure safe operation in typical industrial thermal environments. The asymmetric structure allows installation with a defined flow direction to combine structural support and filtration within one compact panel, reducing the need for additional filter media.

Suitable for

• Server racks and data centre cooling aisles where air filtration and flow guidance are required
• Control cabinets and electrical enclosures in industrial automation systems
• Air-cooled heat exchangers, fans and ventilation assemblies in equipment housings
• Replacement or retrofit applications in existing cooling assemblies

Key specifications

• Material: chopped-fibre mat with progressive (graded) structure
• Dimensions: 221 × 17 × 221 mm
• Operating temperature resistance: up to 100°C
• Fire behaviour: self-extinguishing category F1 (DIN 53 438)
• Porosity: open structure on dust-laden air side, closed structure on clean-air side
• Effective particle retention: from approximately 10 µm

How to use

Install the panel with the open-porosity side facing the incoming dust-laden airflow and the closed-porosity side oriented toward the protected internal space or downstream components. Ensure the panel fits securely within the designated mounting frame or slot to prevent bypass of unfiltered air. Periodically inspect the panel for visible dust loading and reduced airflow; replace the panel once pressure drop or contamination reaches levels that impair cooling performance. Observe the enclosure manufacturer’s guidance for service intervals and access procedures.

Usage recommendations

For optimal performance, verify correct flow direction during installation and maintain a replacement schedule based on operating environment. In dusty or particle-rich settings, check the panel more frequently and consider pre-filters where heavy contamination is expected. Avoid exposure to open flames and ensure the panel is used within the specified temperature range.
