Tri Lobe Blowers with pressure to 1,000 mbar (g), vacuum to 500 mbar (a) & air flow to 25,000 m³/h Innovative Positive Displacement Rotary Lobe Blowers for any application Superior efficiency, low noise emissions, small footprint, minimum maintenance and long service life Robuschi design and manufacture high performance rotary tri lobe blowers that meet any working condition with superior efficiency, low noise emission, small footprint, minimum maintenance, competitive operating costs and long service life. The 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. The cast iron, dynamically balanced tri lobe blower 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. A pair of accurately machined alloy steel, hardened and ground timing gears maintain clearances between the impellers during rotation, resulting in 100% oil free air. Lobe compressor blowers are constant volume machines and as such, deliver a fixed discharge against the system back pressure. It is important to have adequate size piping and large radius bends to maintain high working efficiency and low power consumption.
