Tri Lobe Blowers

Tri Lobe Rotary Positive Displacement Blower, RBS, is an innovative tri lobe rotary blower equipped with a special low pulse system to reduce pressure pulsations. 

It is a positive displacement unit with a pumping capacity determined by size, operating speed and pressure conditions. It operates with two tri-lobe impellers mounted on parallel shafts, rotating in opposite directions within a casing closed at the ends by side plates. As the impellers rotate, air is drawn into one side of the casing and forced out of the opposite side against the existing pressures. The discharge pressure depends upon the system resistance or back pressure.

Lobe compressor blowers are constant volume machines and as such, deliver a fixed discharge against the system back pressure. Recirculating air from the discharge to suction may result in over heating. Using throttle valves in the intake or discharge piping to increase capacity, increases the power load on the motor which may seriously damage the compressor. 

 

Technical informations

The cooled version is equipped with two cooling coils that maintain the oil temperature below 100°C in all working conditions. It is an ideal blower system for situations when the gas discharge temperature exceeds 140°C.

The RBS INOX is a stainless steel version of tri lobe blowers, constructed from stainless steel (AISI 316 or DUPLEX), to provide excellent top performance corrosion resistance in a variety of heavy-duty applications such as wastewater treatment, ozone and evaporation processes. 

Tri Lobe Blowers with pressure to 1,000 mbar (g), vacuum to 500 mbar (a) & air flow to 25,000 m³/h
