ROLINE ventilátorová jednotka 26.21.0019 — 2 ventilátory pre 19-palcovú nástennú skriňu, sivá

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

How to use
