THREE LOBE ROOTs BLOWERS

These blowers made by KUBICEK are devices which deliver compression of a gas media, using two three-lobe rotors (rotary pistons).

 

The parallel rotors are located in a horizontal position within the blower box, and rotate in opposite directions. The movement of the rotary pistons causes the media to be sucked in through the intake port of the device, transported to the destination, and compressed. The system is fitted with a synchronizing gear mechanism with ground spur gears to provide accuracy and fluency in rotor movement. Furthermore, it also serves to limit the no-contact space allowance for rotor operation. These rotors do not need any lubrication, which prevents oil contamination of the media. This is also one of the reasons why ROOTs blowers made by KUBÍČEK have found their use in such a vast number of industries.

Gas blower aggregates

Gas blowers are designed for suction, compression and transportation of flammable, explosive and corrosive gases. They meet the requirements EU Directive 94/9/EC - ATEX called.

Construction of blower is resistant to internal explosion and will not allow its transfer to the surrounding area. Units are equipped with safety features and relevant measuring elements for measuring and monitoring of operational parameters. In combination with the corresponding control system, these units can work in automatic mode with remote data transmission.

Applications

  • Mine gas exhaust stations
  • Increasing the pressure of dry ammonia
  • Transport of coke oven gas
