## Summary description

The EFB Elektronik PRO-LFD04AT.TS is a high-performance cooling fan designed for efficient airflow in rack systems. With a robust plastic housing, it operates at an output voltage of 230 V.

## Long description

The EFB Elektronik PRO-LFD04AT.TS is a cooling fan unit with an integrated thermostat, designed for installation in the roof of equipment cabinets and rack systems. It features a robust black plastic housing, operates from 230 V mains and fits a cabinet roof with a width and depth of 380 mm to provide targeted airflow and temperature control for electronic components.
Advantages
The unit combines ventilation and temperature regulation in a single compact module, reducing the need for separate controllers. For the four-fan variant it offers a three-position switch (0/I/II) that enables a reduced-speed "Silent-Mode" for especially quiet operation, while the two-fan variant uses a simple ON/OFF switch. Its plastic housing is lightweight and corrosion-resistant, and the integrated thermostat maintains a controlled internal cabinet temperature.
Suitable for
 Ventilation of telecom, server and network cabinets
 Cooling of industrial control cabinets and enclosures
 Retrofit or replacement in compatible 380 mm roof-mount openings

How to use
Install the fan unit in the roof cut-out of the cabinet according to the cabinet manufacturer’s mounting instructions, ensuring correct orientation for airflow. Connect the unit to a 230 V supply using appropriate wiring and protective devices.

Verify thermostat settings and allow the unit to regulate internal temperature automatically.

Ensure regular cleaning of fan blades and filter areas to maintain airflow and inspect electrical connections periodically. Use the reduced-speed Silent-Mode where noise is a concern, and confirm compatibility with cabinet roof opening dimensions before installation.
