Twin Lobe Blower

AKASH Twin Lobe Blowers are positive displacement units engineered for high-flow, oil-free air or gas delivery. Their performance is precisely determined by three key factors: blower size & configuration, rotational speed, and system pressure or resistance conditions.

Twin Lobe Blower

AKASH Twin Lobe Blowers are robust, positive displacement machines delivering steady, oil-free air for diverse industrial applications. Featuring two precisely machined lobes rotating in opposite directions within a balanced casing, they provide smooth, continuous airflow with minimal vibration and noise. Ideal for sensitive industries like wastewater treatment, pneumatic conveying, aeration, electroplating, and chemical processing, these blowers ensure clean and reliable air. Built with high-grade materials and alloy steel timing gears, they offer long life, low maintenance, energy efficiency, and consistent performance for demanding industrial operations.

Aeration, filter backwashing, sludge agitation, and bio-treatment basins
Pneumatic Conveying of Powders & Bulk Materials:
Cement, fly ash, food grains, plastic pellets etc.
Chemical & Petrochemical Processes:
Gas transfer, process air supply, vapor recovery, handling non-corrosive gases.
Aquaculture & Fish Farming:
Pond aeration, biofloc systems, maintaining dissolved oxygen levels.
Food, Pharmaceutical & Packaging Industries:

FAQs

1. What is a Twin Lobe Blower and how does it work?

A Twin Lobe Blower is a type of positive displacement machine that uses two interlocking, figure-eight shaped lobes (rotors) to trap air and move it from the inlet to the outlet. This process delivers a consistent volume of air or gas with each rotation, making it highly reliable for applications requiring a steady flow.

2. What are the main applications of Twin Lobe Blowers?

Twin Lobe Blowers are versatile and are commonly used in various industrial applications. These include aeration in wastewater treatment plants, pneumatic conveying for transporting bulk materials, dust collection, aquaculture, and processes that require a continuous, oil-free air or gas supply.

3. What is the difference between an air-cooled and a water-cooled blower?

Air-cooled blowers use ambient air to dissipate heat, making them suitable for most standard applications. Water-cooled blowers, on the other hand, use a continuous flow of water to cool the machine, which is necessary for applications that involve higher pressures or operate in high-temperature environments.

4. How do I choose the right Twin Lobe Blower model for my needs?

Selecting the right model depends on several factors, including the required flow rate (M³/Hr), the operating pressure (MMWG), and the horsepower (BHP) of the motor needed. Our detailed performance table provides a range of options to match different requirements. For specific guidance, you can contact our technical team for a personalized recommendation.

5. Are Twin Lobe Blowers easy to maintain?

Yes, Twin Lobe Blowers are known for their simple and robust design, which makes maintenance straightforward. The lack of internal contact between the lobes and the housing means there is minimal wear and tear. Regular maintenance typically involves checking oil levels, replacing filters, and inspecting belts or couplings, which can be easily managed to ensure long-term performance.
