ROLINE 19 tuuman tuuletinyksikkö, 4 tuuletinta, harmaa, malli 26.21.0077

ROLINE 19-inch cooling fan unit with four integrated fans, model 26.21.0077, is a rack-mount ventilation module designed for standard 19" server racks and network cabinets. The unit delivers targeted airflow to assist heat dissipation from active equipment, helping maintain stable operating temperatures in server rooms, network closets, and office racks. Its grey housing matches common rack interiors and allows straightforward installation in horizontal or vertical rack positions depending on available space and airflow needs.

Advantages

The unit combines four fans in a compact 19-inch format to provide increased airflow where cabinet ventilation is limited. Its design enables localized cooling directly above or below heat-generating equipment, improving temperature control without the need for full-room HVAC adjustments. The grey finish and standard rack width ensure compatibility with most enclosures, while the integrated fan assembly reduces cable clutter and simplifies maintenance compared with multiple individual fans.

How to use

Install the cooling fan unit into a standard 19" rack space at the position where additional airflow is required, typically above or below heat-generating equipment. Secure the unit using appropriate rack screws or mounting brackets. Connect the power lead(s) to the rack power distribution unit or a suitable power source following electrical safety guidelines. Verify that airflow direction aligns with the intended cooling strategy (intake or exhaust) and confirm that vents on adjacent equipment are not obstructed.

Recommendations

For effective temperature management, position the unit to address known hotspots and ensure unobstructed air paths. Combine with regular rack airflow assessment and, if available, temperature sensors to monitor cooling performance. Periodically clean fan intakes and check mounting hardware to maintain reliable operation.
