to 1400 m³/h


  • Ultra-compact case. Does not require commissioning works. It is enough to connect the installation to the electric network and mount the air duct system.

  • Saves up to 85% of energy and operating costs due to the most energy-efficient components.

  • Built-in automation. The controllers and all control elements are already set up and ready to go. The units are equipped with flow control and pressure support sensors.

  • Control the unit at any time from anywhere in the world with all convenient devices.


  • Water heating.

In case by means of utilization of heat of the removed air it is not possible to reach the set temperature of supply air, there is an opportunity to install additional air heater.

  • Electric heating

  • Freon cooling

  • Bypass

  • Conn. air quality sensor / sensor



Filtration class: Coarse

The initial resistance of a clean filter is 110 Pa.

Energy efficient EC motor

Brushless synchronous motor with electronic control. The speed is adjusted depending on the required load which leads to significant energy savings compared to the usual cycle of cascade power on-off, as well as reduces noise level.

  • EC-MOTOR WITH EFFICIENCY ABOVE 90% saves at least 30% more electricity than an AC motor.

  • Built-in EMC filter protects against phase loss and low voltage in the network.

  • Protection against overheating of the motor and electronics, and protection against rotor lock.

  • No starting currents.

  • The absence of the frequency converter saves installation space.

  • Allows reduction of the rotation speed up to 10%.

  • Possibility of data exchange via MODBUS RTU protocol

  • Flow Grid technology: air flow rectifier

  • Wide range of rated voltage: 1~200..277 V  & 380-480 V

  • Long service life: more than 80 000 hours of continuous operation.

  • High working pressure: up to 2500 Pa.


In rotary recuperators, heat transfer from the exhaust air to the supply air is carried out through a rotating cylindrical rotor, which consists of a package of thin metal plates. This solution reduces energy consumption by 30%.

  • Foil thickness: from 1.4 to 1.8 mm.

  • Height of foil waves: from 1.6 to 2.5 mm.

  • Moisture recovery depends on the temperature difference between the outside and exhaust air.

  • Efficiency: up to 88%, depending on the size and operating parameters.

  • Minimal energy losses per square meter of surface.

  • Improved thermal insulation.

  • Increased mechanical strength.
