Explosion-proof Roots blowers are critical equipment for handling air and gas in hazardous areas where explosive atmospheres may occur. Our company specializes in designing and manufacturing explosion-proof three-lobe Roots blowers that meet international safety standards. These blowers are widely applied in petroleum, chemical, coal mining, metallurgy, and municipal wastewater treatment. With strict quality control and advanced production technology, we ensure that every blower delivers stable performance and long service life even in the most demanding environments.

The explosion-proof design is the core of our Roots blowers. The motor used is a certified explosion-proof motor with a protection class suitable for Zone 1 and Zone 2 hazardous areas. All electrical components are sealed to prevent sparks. The casing is manufactured from high-strength cast iron, and the impellers are precision-machined to ensure minimal clearance. A special mechanical seal prevents gas leakage. In addition, the blower is equipped with a pressure relief valve and temperature sensors to enhance operational safety.

Our three-lobe Roots blowers offer excellent performance with high volumetric efficiency and stable airflow. The unique rotor profile reduces pulsation and noise, making the blower suitable for continuous operation. The structure is compact, and the bearing housing is designed for easy maintenance. All parts are interchangeable, which reduces downtime and maintenance costs. These blowers are also available in various configurations, including belt-driven and direct-driven types, to meet different site requirements.

Technical parameters include an air volume range from 1.2 to 300 cubic meters per minute, a pressure range from 9.8 to 98 kPa, and a motor power from 0.75 to 355 kW. The maximum allowable temperature of the gas delivered is 150 degrees Celsius. The blower can be customized with different materials, such as stainless steel impellers or coated casings, for corrosive or high-temperature media. We also provide explosion-proof certifications for various international standards, including ATEX, IECEx, and CCC.

This type of blower is widely used in pneumatic conveying, sewage aeration, flue gas desulfurization, vacuum packaging, and chemical reaction processes. In coal mines, it is often used for gas drainage and ventilation. In the petroleum industry, it helps in vapor recovery and inert gas generation. The explosion-proof feature ensures that the blower will not become an ignition source, protecting both personnel and equipment. Regular maintenance is simple, and the blower can run unattended for long periods with proper lubrication. For example, in wastewater treatment plants, these blowers provide continuous aeration to support biological treatment processes.

As a professional manufacturer, we have more than 20 years of experience in producing Roots blowers. Our factory is equipped with CNC machining centers and a complete testing platform. Every blower undergoes rigorous performance tests, including flow rate, pressure, noise, vibration, and temperature rise. We hold ISO9001 quality management certification and have exported to more than 30 countries. Our technical team can help you select the right model based on your specific process conditions and safety requirements.
