SCREW blower units
A new innovation in the production program is a series of highly energy-efficient, so called screw blower units KUBÍČEK with SD28, SD38, SD45 and SD55 of our own design and production.
Innovative solutions, combining the best of the world of ROOTs blowers and Screw Compressors.
Power consumption is a highly monitored parameter and forms the largest part of the operating costs of blowers. This is true for almost all applications. Compared to a classic ROOTS blower, KUBÍČEK screw blowers offer significantly higher efficiency from 50 kPa and above.
Using a proven chassis and noise cover design that is identical for both screw and existing ROOTS blowers, the design allows for a unique interchange of ROOTS /SCREW power stages (by interchanging of older ROOTs stage, the customer gets a full-featured economical screw blower).
Due to the design of the sealing elements and the internal oil circulation, KUBÍČEK screw blowers do not need any additional oil pump or large volume oil management with cooler.
High precision longitudinally mounted rotors in combination of 4+3 profile are developed and manufactured in our company in Velke Losiny, Czech Republic.
KUBÍČEK screw blowers are the most suitable solution for pressure applications with continuous or regulated operation up to 100 kPa (1000 mbar).
High precision of manufactured parts, perfect shape – KUBÍČEK screw blowers surpass conventional positive displacement blowers in efficiency!
We are currently mass producing the first of 4 sizes of screw blowers, namely the largest model with connection dimensions DN200 and with engine power up to 90 kW. It will be mounted on a standard DN200 chassis – dimensions with cover – 1930*1570*1660 mm (l*w*h)
KUBÍČEK brings a precise and yet simple solution that is always designed with the requirements of each customer in mind.
