1U fan block ProBase SR3.1.2 19 inch for switching cabinet, model FAN-1U2-S

The ProBase SR3.1.2 1U fan block for 19-inch switching cabinets (model FAN-1U2-S) is a rack-mount ventilation module engineered to provide forced airflow inside standard 19" cabinets. Installed in a single 1U slot, this compact fan unit helps reduce internal temperatures and supports reliable operation of network switches, servers and telecom equipment by improving heat dissipation within the rack enclosure.

Advantages

This 1U fan block delivers targeted airflow in a slim rack profile while keeping installation space to a minimum. The unit is designed for compatibility with 19" cabinets, allowing straightforward mounting in standard rack rails. By promoting consistent air circulation, it helps stabilize operating temperatures and can extend the service life of sensitive electronic components. The modular 1U design enables flexible placement where additional ventilation is required without occupying multiple rack units.

Suitable for

• Data centre racks and server rooms that require supplemental rack-level cooling
• Telecommunications racks and distribution frames in wiring closets
• Network closets with limited space needing a 1U ventilation solution
• Enclosures housing switches, routers, small servers or storage devices

Key specifications

• Form factor: 1U rack-mount module for 19" cabinet
• Function: forced ventilation to improve internal rack airflow
• Mounting: fits standard 19" rack rails in a single U
• Physical profile: low-height, space-saving 1U design
• Application environment: data centres, server rooms, telecom racks and network cabinets

How to use

Install the fan block into an available 1U position in a standard 19" rack, securing it to the rack rails according to the cabinet mounting method. Connect the unit to the cabinet's power source or the rack power distribution unit following site electrical guidelines. Position the fan module where additional airflow is needed to assist front-to-back or bottom-to-top cooling patterns, and verify airflow direction and clearance for unobstructed ventilation. Monitor cabinet temperatures after installation to confirm the desired cooling effect.

Usage recommendations

Place the fan block near heat-generating equipment and maintain clear intake and exhaust paths to maximize efficiency. Ensure electrical connections comply with local standards and use appropriate fuses or breakers. Regularly inspect and clean fan inlets and filters if present to prevent dust buildup and preserve airflow performance.
