Twin Lobe Roots Air Blower

Product Overview

Product Details: A Twin Lobe Air Roots Blower is a type of positive displacement blower that is widely used for supplying oil-free, pulsation-free air or gas at constant volume under varying pressure conditions. It is especially suited for low to medium pressure applications and provides a continuous, uniform airflow. The blower consists of two lobed rotors (each with two lobes, hence "twin lobe") rotating inside a precisely machined casing: The rotors rotate in opposite directions, synchronized by external timing gears. As they rotate, air is trapped in the pockets between the rotor lobes and the casing wall. This air is carried from the inlet side to the outlet side without compression inside the casing. Actual compression happens when the air is discharged into the system and meets resistance (back pressure). Note: Since there is no internal compression, the discharge pressure depends entirely on the system’s back pressure. Rotors (Twin Lobe): Dynamically balanced for vibration-free operation. Casing: Heavy-duty cast iron or steel, precision machined. Timing Gears: Hardened alloy steel, externally lubricated. Bearings: Anti-friction type (roller or ball bearings). Sealing System: Prevents air leakage and oil contamination. Drive System: Typically belt-driven or direct coupled to a motor. Type: Positive displacement, external compression blower Cooling: Air-cooled (standard); water-cooled for high temperature/pressure Lubrication: Oil-lubricated at gear end; grease-lubricated at drive end Capacity Range: 10 – 10,000+ m³/hr Pressure Range: Up to 1 bar (g) or -500 mbar (vacuum) Speed Range: 500 – 3000 RPM depending on size and application Construction: Rigid, robust design for long operating life Wastewater treatment (aeration tanks, sludge agitation) Pneumatic conveying systems Aquaculture (pond aeration) Cement, chemical, and food industries Electroplating, galvanizing Paper mills Vacuum packaging and central vacuum systems Combustion air supply Oil-free air delivery (no oil in the compression chamber) Consistent flow rate regardless of back pressure Simple construction with fewer moving parts Low maintenance and easy serviceability Suitable for continuous duty operation Customizable for specific industrial need
