Tuuletinyksikkö EFB Elektronik PRO-LFD02AT.GR

The EFB Elektronik PRO-LFD02AT.GR is a cooling fan unit with an integrated thermostat, designed for mounting in the roof of 19" cabinets and racks. It is intended to maintain stable temperatures in equipment enclosures and comes with the required mounting accessories. The unit has a plastic housing finished in light grey (RAL7035) and is built for installation in an A-type opening (380 x 380 mm). The fan operates from AC mains (230 V, 50 Hz) and is supplied as a single unit per pack.

Advantages

The fan unit combines a thermostat and a compact plastic housing for straightforward installation into standard 380 x 380 mm roof openings. For the 4-fan variant a 3-stage speed switch (0/I/II) allows reduced-speed "Silent-Mode" operation for quieter cooling; the 2-fan variant uses a simple ON/OFF switch. The unit is supplied complete with mounting accessories and is available in a light grey finish matching typical rack equipment.
