Description
Description
APPLICATION
  • Supply and exhaust ventilation and air conditioning systems for various premises requiring cost-effective solution and controllable ventilation.
  • EC motors applied in VKM fans reduce energy demand by about 35 % and ensure high aerodynamic performance and low noise level.
  • Such characteristics are of special importance for ventilation of public premises as banks, supermarkets, restaurants, hotels, installation close to residential buildings and for domestic application, e.g. ventilation of private pools.
  • EC motors enable integration of several fans into a unified networks and their centralized control.
  • The steel casing ensures reliable operation of the fan in case of its outside installation.
  • The fans are designed for connection to Ø 100, 125, 150, 160, 200, 250 and 315 mm air ducts.
DESIGN
  • The fan casing is made of polymer coated steel.
  • New technologies for manufacture of the fan components let attain the total casing air tightness.
MOTOR
  • The impellers with backward curved blades are powered with a high efficient electronically commutated (EC) direct current motor with external rotor.
  • As of today, such motor type is the most advanced solution for energy saving.
  • EC motors are featured by high performance and the best speed controllable range.
  • Premium efficiency reaching up to 90 % is the absolute advantage of electronically commutated motors.
  • The motors are equipped with ball bearings for longer service life of the fan (40 000 hours).
  • For precise features, safe operation and low noise, each turbine is dynamically balanced while assembly.
  • Motor ingress protection rating IP44.
SPEED CONTROL
  • The fan is controlled with the external control signal 0-10 V (air flow control as a function of temperature, pressure, smoke conditions and other parameters).
  • Should the control value get changed, the EC motor adjusts its speed and the fan boosts as much air flow to the ventilation system as required.
  • Maximum speed of the fan does not depend on the current frequency and it can operate at 50 or 60 Hz mains supply.
  • The fans may be integrated into the unified dispatch system.
  • The respective software enables to control all the fan integrated into the system.
  • The computer displays all the system parameters.
  • Each fan in the system may be individually adjusted.
MOUNTING
  • The fans may be installed at any angle.
  • The fixing brackets that are included into the delivery set are used to facilitate the fan mounting to the wall.
  • The fan is connected to power mains through the external terminal box.
