Application:

Essima ES series tangential fans due to their compact design and low noise are widely used as a ventilation unit in floor-mounted heat convectors and other equipment that requires small size and silent operation.

Design features:

Essima cross flow fans are designed with supply voltage 12/24VDC . Model range differs mostly by the wheel size and includes diameters 30 and 40 mm and length 190, 290 and 350 mm. Motors used in ES series are 3-phase sine wave DC motors. They provide high efficiency and low noise level of the device. ES series DC fans allow to adjust rotation speed of the wheel. 2 options of speed adjustment are available - by PWM or voltage control. In order to reduce weight and vibrations we use aluminium to produce our fan wheels. This material is also applicable due to its high strength, long life and temperature resistance characteristics. Power connection of the device is provided by means of 330 mm wires with a socket at the end. Essima cross flow fans model range is not limited with ES series and can be enlarged according to customers specification.

General characteristics:

  • Supply voltage 12/24VDC.
  • Fan wheel diameter 30 and 40 mm.
  • Air flow width ranges from 190 mm to 350 mm.
  • Speed adjustment — PWM or voltage control (0...10V).
  • Motor type – 3-phase 12-pole sine wave DC motor.
