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.
