Rack cooling equipment Rittal 3173.105, fiber material, 289×289×17 mm

Rittal 3173.105 rack cooling insert is a passive airflow and filtration component designed for integration into server, network and telecommunications racks. Constructed from a chopped-fibre mat with a progressive structure, the insert measures 289 × 289 × 17 mm and is intended to support ventilation and temperature control inside enclosures. The material is temperature-resistant up to 100°C and meets self-extinguishing category F1 to DIN 53 438. The insert provides an open structure on the dust-laden air side and a closed structure on the clean-air side, enabling reliable filtration of particles from 10 µm and an improved internal airflow pattern without active fans.

Advantages

The Rittal rack cooling insert combines passive airflow guidance with dust filtration in a single lightweight component. Its progressive chopped-fibre mat captures virtually all types of dust from 10 µm upwards while maintaining a low-pressure-drop design to support existing rack cooling systems. The material’s temperature resistance to 100°C and F1 self-extinguishing rating add an extra level of safety in environments with elevated temperatures. Designed for straightforward installation into standard rack openings, the insert minimizes complexity when improving enclosure ventilation and protecting sensitive components from particulate contamination.

Suitable for

• Server and data center racks requiring passive airflow management
• Telecommunications and network cabinets with dust-prone environments
• Industrial control enclosures where particulate filtration and thermal resistance are needed
• Retrofit projects to add filtration without changing active cooling systems

How to use

Install the Rittal 3173.105 insert into the designated rack or cabinet opening according to the enclosure manufacturer’s mounting points. Ensure the open-structure side faces the incoming dust-laden airflow and the closed side faces the internal, cleaner air zone. Check that the insert fits securely and does not obstruct mechanical doors or fans. Regular visual inspection will indicate when the filter surface accumulates dust; replacement or cleaning should be scheduled according to the environmental conditions and the enclosure’s maintenance plan. No electrical connection or active components are required for operation.

Usage recommendations

For optimal performance, position the insert where it can intercept incoming air before it reaches sensitive components. In high-dust environments, increase inspection frequency and replace the insert when pressure drop or visible loading affects airflow. Combine the insert with regular enclosure cleaning and proper cable management to maintain effective ventilation and prolong component life.
