Helical Lobe Blowers are advanced positive displacement blowers designed to deliver a smooth, continuous flow of air or gas with low pulsation, reduced noise, and high efficiency. These blowers use specially twisted helical rotors that compress and transfer air from the inlet to the discharge side with exceptional reliability. They are widely used in industries such as wastewater treatment, cement, pharmaceuticals, food processing, and pneumatic conveying.
TMVT Industries Pvt. Ltd. is one of India’s leading manufacturers of industrial blowers and vacuum systems, offering robust helical lobe blowers engineered for long service life and energy-efficient operation. TMVT has over 50 years of engineering experience and serves customers in more than 56 countries worldwide.
What Is a Helical Lobe Blower?
A Helical Lobe Blower is a type of roots blower in which the lobes are twisted along the rotor axis. This helical design reduces pressure pulsations significantly compared to conventional straight-lobe blowers. The result is quieter operation, lower vibration, and improved mechanical life.
Unlike compressors, these blowers do not internally compress air. Instead, they trap a fixed volume of air and move it from the suction side to the discharge side, ensuring constant flow regardless of pressure changes within the operating range.
Key Features of Helical Lobe Blowers
Low Noise and Vibration
The helical rotor profile provides gradual air displacement, reducing pulsation and noise levels.
Oil-Free Air Delivery
The air chamber remains completely isolated from the lubricated gear and bearing sections, ensuring contamination-free air.
Energy-Efficient Operation
Precision-machined components and optimized rotor geometry reduce power consumption and improve volumetric efficiency.
Rugged Construction
Manufactured with high-grade cast iron casings, hardened alloy steel shafts, and dynamically balanced rotors.
Easy Maintenance
Simple construction and splash-lubricated bearings make servicing straightforward and cost-effective.
Working Principle
Helical lobe blowers operate on the positive displacement principle. Two synchronized lobes rotate in opposite directions without touching each other or the casing. Air enters the inlet, gets trapped between the lobes and casing, and is transported to the outlet. The helical profile ensures a more uniform discharge and reduced shock loads on bearings and gears.
Applications of Helical Lobe Blowers
Helical lobe blowers are used in a wide range of industrial processes:
Sewage Treatment Plants (STP)
Effluent Treatment Plants (ETP)
Pneumatic Conveying Systems
