ROLINE 19in Fan Unit 4 Fans with Thermostat, model 26.21.0272 — rack cooling accessory

ROLINE 19in Fan Unit with four fans and integrated thermostat is a rack-mounted cooling accessory designed for 19-inch server and network cabinets. The unit provides directed airflow across mounted equipment to support temperature regulation in data cabinets, communication racks and compact IT closets. The integrated thermostat enables automatic fan control based on internal temperature, helping maintain stable operating conditions for installed hardware.

Advantages

The fan unit combines multiple axial fans in a single 19-inch module to deliver concentrated airflow while occupying minimal rack space. The integrated thermostat reduces manual intervention by adjusting fan speed according to temperature, which can improve energy efficiency compared to fixed-speed units. The unit is compatible with standard 19-inch mounting, making installation straightforward in most server and network cabinets.

Suitable for

• Small to medium server cabinets and wall-mounted network racks
• Telecommunications and network equipment enclosures
• IT closets and edge cabinets with limited ventilation
• Environments requiring selectable or automatic fan control for temperature-sensitive devices

Key specifications

• Form factor: 19-inch rack mount
• Number of fans: 4 fans providing directed airflow
• Thermostat: integrated temperature-controlled fan activation
• Mounting: front or top placement in standard 19-inch cabinets depending on cabinet layout
• Purpose: active ventilation for server and network equipment

How to use

Install the fan unit into a compatible 19-inch rack position using appropriate mounting hardware. Position the unit to direct airflow toward heat-generating components or to exhaust warm air from the cabinet, according to your cabinet layout. Connect the power supply and set the thermostat to the desired activation temperature; the fans will run automatically when the internal temperature exceeds the set point. Regularly verify airflow and temperature readings to ensure the unit operates as intended.

Recommendations

For effective cooling, place the fan unit where it can create a clear airflow path through the cabinet. Avoid obstructing intake or exhaust vents and maintain a regular cleaning schedule to prevent dust accumulation on fan blades and filters. If the cabinet contains high-density equipment, consider combining this fan unit with additional ventilation or spot cooling to maintain recommended operating temperatures.
