Computer cooling system part Rittal 3173.100 — fiber panel, grey, 289×289×17 mm, air-cooled

Rittal 3173.100 is a grey fiber panel designed for air-cooled enclosure systems. With dimensions of 289 × 289 × 17 mm, this chopped-fibre mat component features a progressive structure: an open side for dust-laden air and a closed side for clean air. It is temperature-resistant to 100°C and meets self‑extinguishing category F1 to DIN 53 438, providing reliable filtration of particles from 10 µm and supporting thermal management in industrial and IT cabinets.

Advantages

The fiber panel combines a two-sided structure that traps dust on the open, dust-laden side while maintaining a closed, clean-air surface on the opposite side, which helps protect internal components. Its progressive chopped-fibre construction increases filtration efficiency for particles down to 10 µm without significantly restricting airflow. The material’s temperature resistance up to 100°C and F1 self‑extinguishing rating offer increased safety and durability in heat-generating environments. The compact 289×289×17 mm format fits standard panel openings and simplifies replacement and maintenance operations.

Suitable for

• Air-cooled enclosures and cabinet ventilation systems
• Industrial control cabinets and switchgear
• IT racks and server cabinets requiring particulate filtration
• Applications where compact, replaceable intake filters are needed

Key specifications

• Material: chopped-fibre mat with progressive structure
• Dimensions: 289 × 289 × 17 mm
• Color: grey
• Temperature resistance: up to 100°C
• Fire behavior: self‑extinguishing category F1 (DIN 53 438)
• Filtration capability: reliable removal of particles from 10 µm
• Surface structure: open side for dust-laden air, closed side for clean air

How to use

Install the panel into the designated intake or filter holder of the enclosure with the open, dust-laden side facing the incoming airflow and the closed side oriented toward the interior of the cabinet. Ensure the panel seats evenly in the frame to avoid bypass paths. Replace the panel at regular intervals or when visibly loaded with dust to maintain airflow and cooling performance. Handle the panel carefully to avoid compressing the mat, which could reduce filtration efficiency and airflow.

Usage recommendations

For optimal performance, check the panel during routine maintenance and replace it when particulate buildup increases pressure drop or when visual inspection shows saturation. In environments with heavy contamination, consider shortening replacement intervals and combining the panel with coarse pre-filters or regular external cleaning of intake areas.
