Units containing ROOTs blowers from KUBÍČEK VHS are devices in which external compression of the gaseous medium takes place by means of two three-tooth rotors (rotary pistons). These are mounted longitudinally in parallel axes in the blower housing and rotate in the opposite direction. The movement of the rotary pistons causes the medium to be sucked on the suction side of the device, transported to the discharge point and compressed. The system is equipped with a synchronizing gear with ground bevel gearing, which ensures the accuracy and smoothness of rotation of the rotors. At the same time, it defines the clearance for non-contact rolling of the rotors, which thus does not need to be lubricated and therefore the medium cannot be contaminated with oil.
We currently produce 22sizes of ROOTs blowers
ΔP = 0 – 100 kPa
Q = 15 – 20 000 m3/hour
Electric motor power
P1 = 0,25 – 560 kW
DN = 50 – 500
The overall concept of the unit arrangement is designed with emphasis on maximum reliability and functionality, easy inspection, maintenance and accessibility of individual parts of the unit even in the acoustic cover.

Frequently asked questions
What is the noise level of the unit?
For all sizes of unts, we produce our own acoustic covers, adapted to the location and customer requirements. These in conjunction with our silencers show a high noise attenuation efficiency.
At the same time, we design the set in the middle band of the speed spectrum so that the resulting sound pressure level is as low as possible.
