BORA – Travaini blower
Positive displacement blower. The gear toothed wheels that allow the rotors and their bearings to rotate are lubricated with oil and are inside two compartments (separated from the rotor rotation chamber by means of gaskets) and they function as a tank for the lubricating oil.
- During operation they are at the same pressure of the pump work chamber.
- For this reason it is forbidden to open the oil filler and drain plugs during operation or until the atmospheric pressure has not been restored inside the pump.
Models: 73 / 103 / 163 / 233 /293 / 353 / 463 / 673
BORA Exhausters Traivaini blower
Positive displacement Exhauster. The lobe pumps are volumetric machines that, thanks to the rotation of two rotors with three lobes within a suitably shaped chamber, create volumes and transfer air through the intake manifold to the outlet one. The rotor lobe rotation without contact is synchronized by means of gears and it occurs completely dry without any lubrication or residues generated by brushing or contact during rotation.
BORA Booster HV Travaini Blower
High vacuum booster. Blowers are pumps operating without oil inside the hydraulic chambers. They include the centrifugal-volumetric blowers series, from size 73 to size 103 and the volumetric series from size 163 to size 883. They are intended to be used as a component of a more complex system that processes clean air or not aggressive/explosive gases.
- These machines are suitable to operate with positive back pressure in delivery.
