ROLINE fan unit 26.21.0019 — 2 fans for 19 inch wall-mount case, grey

ROLINE fan unit 26.21.0019 is a replacement cooling module designed for 19" wall-mount network and server cabinets. The compact grey housing integrates two fans to provide directed ventilation for wall-mounted enclosures, helping to remove heat and maintain airflow around switches, routers, patch panels and small servers. The unit is intended for use where additional forced ventilation is required to support reliable operation of installed equipment.

Advantages

The two-fan configuration delivers increased airflow compared to a single fan, improving heat dissipation in confined wall-mounted racks. The grey housing is compatible with standard 19" cabinet aesthetics and mounts securely in designated fan slots. The unit is a straightforward replacement module that restores or improves ventilation without modifying existing enclosure wiring or structure. Designed for continuous operation, it supports stable temperatures under typical network workloads.

Suitable for

• Ventilating 19" wall-mount network cabinets and enclosures
• Cooling switches, routers, patch panels and compact servers
• Replacing worn or failed fan modules in wall-mounted racks
• Improving airflow in small telecom or IT closets

Key specifications

• Configuration: dual fan unit in a single grey housing
• Mounting: designed for 19" wall-mount cabinet fan slot
• Purpose: forced ventilation for small racks and enclosures
• Operation: continuous ventilation to assist heat removal
• Compatibility: intended for standard 19" wall-mount networking and server enclosures

How to use

Power down equipment if required by your enclosure maintenance procedures, then remove the existing fan unit if present. Insert the ROLINE dual-fan module into the designated 19" wall-mount fan opening and secure it according to the cabinet's mounting method. Connect the fan power connector(s) following the cabinet wiring layout or fan controller instructions. After installation, verify fans run and monitor inlet and exhaust temperatures to confirm improved airflow and stable operating conditions.

Recommendations

Install the fan unit in accordance with the cabinet manufacturer's guidance and local electrical safety regulations. Ensure adequate clearance for airflow, keep inlet and exhaust vents free from obstructions, and include periodic checks for dust accumulation. Replace or service fans promptly if unusual noise or reduced airflow is observed to maintain reliable equipment operation.
