37-132kW Oil-Free Screw Blower for Wastewater Treatment: Industrial Screw Blower with Stable Airflow

B-Tohin BLG250LA 37-132kW Industrial Oil-Free Screw Blower for Wastewater Treatment
 
The B-Tohin BLG250LA Industrial Screw Blower is designed for reliable and efficient air supply in industrial applications. Featuring advanced screw compression technology, this blower delivers stable airflow and is suitable for continuous operation in wastewater treatment plants, sewage aeration systems, and various industrial processes.
 
Main characteristics
1,The male and female rotors of oil-free screw blower are precisely designed. Compared with Roots blower, it can achieve internal compression in the cavity, with higher efficiency and 20% higher energy saving performance under the same energy consumption conditions.
 
2,Stable airflow, less airflow fluctuation when pressure changes .
 
3,Applicable to higher pressure, low noise.
 
4,Available with PLC intelligent remote control and different communication methods, convenient for operation management.
 
The screw blower achieves internal compression during the air transportation in the cavity, so the screw blower has most of the advantages of traditional blowers, and at the same time has higher efficiency.
 
The process of air transportation and compression is continuous and progressive, so the airflow pulsation is lower, and the exhaust noise and temperature control are better than traditional blowers.
 
As a new type of rotary blower developed in recent years, screw blowers have begun to be applied in aeration, gas-water back-washing, oxidative de-sulfurization, fluidization/homogenization process, and pneumatic conveying due to their simple structure, stability, energy saving and low noise.
 
 

 
 
 
 
 
 
 
 
 
 
 
 
                                              
 
 
Composition
 
The screw blower is composed of blower enclosure, blower main body, motor, air filter, silencer, an oil pump tank and oil filter.
As the core component of the screw blower, the structure of the blower main body directly determines the blower’s performance. The main body is composed of casing, screw rotors, gear box, bearings, shaft seals, ect.
