Duct fans VKM i VKMS
Duct fans for round systems with a capacity of up to 5260 m3 / h
The VKM and VKMS series are designed for supply or exhaust systems of individual rooms, individual buildings, collective residence and public utilities. For ventilation with increased requirements regarding noise level, Q or E variants are recommended.
VKMS fans differ from similar VKM models with engine power.
The fans use single-phase motors with ball bearings, with an external rotor and curved blades to the rear. The motors have built-in protection with an automatic restart to prevent them from overheating.
The capacity regulation can be performed smoothly (thyristor controller) or in a step-wise manner (transformer regulator). It is possible to connect several units to one controller, provided that the available power and operating current will not exceed the nominal parameters of the regulator.
The fans can be mounted at any angle to the ground, wall or ceiling (brackets included).
Engine safety class: IP X4
VKMS – engine with increased power
VKM E – economical fan operation
VKM Q – engine with reduced power
