ROOTs blower units
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 22 sizes of ROOTs blower units.
ΔP = 0 – 100 kPa
Q = 15 – 20 000 m3/hour
Electric motor power
P1 = 0,25 – 560 kW
DN = 50 – 500
Main advantages 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.
- Low operating costs
- Easy operation
- Optimized rotor and housing shape that significantly reduces pulsations
- Easy access to all service points thanks to opening or removable panels
- Safety – we supply safety or combined membrane valves and backflow valves of our own production as standard, these ensure maximum protection and precision of the blower operation
- Minimum built-up area
- Low noise thanks to special design of combined discharge silencer
- Long life
- Extra fast warranty and post-warranty service
The most common use
- Aeration of tanks at the WWTP
- Washing of sand filters at drinking water treatment plants
- Pneumatic transport
- Transport and compression of non-explosive and non-aggressive gases
- Aeration of fish tanks and pools
- Transport of combustion air to blast furnaces
- Transport of drying and blowing air into the technology

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.
How fast will you process my inquiry?
