Screw Blower

A screw blower is an efficient air compression device used in various industries. It works by using two interme-shing rotors to trap and compress air, providing a steady flow with minimal pulsation. This makes it ideal for processes needing consistent air pressure.

Known for energy efficiency, screw blowers consume less power and operate quietly. Their compact, robust design ensures easy installation and low maintenance, making them cost-effective.

Commonly used in wastewater treatment, pneumatic conveying, and aeration, they are also essential in industries like food, pharmaceuticals, and chemicals where clean, oil-free air is required.

With advanced control systems, screw blowers adjust output to match demand, enhancing efficiency. Their durability and performance make them a top choice for optimizing operations and reducing energy costs.


Maximize airflow efficiency with Luoyou's industrial screw blower systems – engineered for high-volume, low-pressure applications delivering consistent air performance for demanding industrial processes and environmental systems.


Advanced Screw Blower Engineering

Our rotary screw blower technology combines twin-rotor design with precision manufacturing to deliver large volumes of compressed air at low pressures (0.3-2.0 bar). Unlike traditional centrifugal blowers, screw blower systems provide consistent flow rates independent of back pressure variations, ensuring reliable performance across diverse operating conditions.

    Brief:
    A blower is a type of mechanical device that is mainly used to transport air or other gases. It works by the rotation of impellers or vanes inside, which increases the pressure of the gas and forces it to flow. Blowers are widely applied in various fields such as industrial ventilation, pneumatic conveying systems, and wastewater treatment plants. They come in different types, including centrifugal blowers and positive displacement blowers, each with its own unique features and suitable applications. Compared with some other gas delivery equipment, blowers are often known for their relatively high flow rate and moderate pressure capabilities.
