Generally roots blower has capacities from 10 m3/hr. Tri Lobe Positive Displacement Blowers This type of roots blower is advance version of all available PD blowers where tri lobe impelled performs quicker operation than conventional blowers. In other terms these are high volume low pressure positive displacement comprising and called as PD types roots blower. There are various types of Blowers as below Small PD Type Roots Blowers This is a heavy duty root blower available with different performance range in terms of flow rates, pressure, vacuum capacity and Horsepower. This conveying system is derived customize as the requirements based on material transfer rate, filter and cyclone capacity. Root blower is an engineering product also known as twin lobe rotary compressor or twin lobe roots exhausters or roots vacuum pumps. to 14000 m3/hr. PD type roots blowers can be operated on differential pressure and containing volume characteristics. This blower is used in various systems and plants like Sewage Treatment Plants, Pneumatic Conveying Systems, Central Vacuum Cleaning System, Aeration in Storage silos, Blending, Charging of Kilns in Cement and Steel Plants, Effluent Treatment Plants, Dewatering, Water Treatment Plants, Air Drying etc. Roots vacuum pumps are available with air cooled design or water cooled design as per your application. Pneumatic Conveying System Pneumatic conveying system is a tool to transport dry bulk material either by vacuum or by pressure of Air. Thus the air delivery is completely oil free. This is an operating mechanism without internal lubrication requirements. You can also categorize roots vacuum pump or PD type roots blower on three different ways like small positive displacement blower, large positive displacement blowers and tri lobe positive displacement blowers. External power drive one lobe which rotates another lobe with equal ratio gears rotates the both lobes in different direction. . Based on the property of conveying material, the specific velocity airs carry the material to the final destination.Ahmedabad, India March 29, Polyester dehydrating fabrics-HD005 Company 2012 - Twin Lobe Root Blowers for Sewage Treatment Plants Twin Lobe Blowers also known as Roots blowers based on the category of positive displacement blowers. Pair of involutes profiled lobes rotating inside the oval shaped casing, closed at ends by side plates.4 cm to 50. Rotating rotors draw the air into inlet side of the cylinder and push towards the outlet side against the system pressure. Large Positive Displacement Blowers These types of PD blowers or roots vacuum pumps available for air & gas both applications on various sizes of diameter 25. Pneumatic conveying is widely used in various food and Pharma industries, cement industry, aluminium plant and chemical-fertilizer processes
