Oil-Free Screw Blower (LG Series)
This series of screw blowers is a double-screw model produced by our company, which has broken through the bottleneck of high energy consumption and low pressure in traditional blowers. It boasts advantages such as smaller size, higher pressure, lower energy consumption, larger flow rate, less noise, and longer lifespan compared to other similar blowers.
This product offers about 20% higher energy efficiency than the Roots blower.
Imported flow, boost, as follows:
(Product Execution Standard: JB/T 8941-2014)
Series | Bore size | Imported Traffic | Highest Boost Voltage | Matching motor power | Note |
LG150 | 125 or 150 | 8.2~23.6 | 120 | 11~55 | Air-cooled |
LG180 | 200 or 250 | 25.6~73.3 | 120 | 30~200 | Air-cooled |
LG220 | 250 or 300 | 34.2~118.6 | 170 | 75~355 | Chassis Air Cooling |
Industry Applications: Sewage Treatment, pneumatic conveying, power, cement, mining, chemical industry, metallurgy, and other sectors; the series products convey clean air as the medium.
The LG series energy-saving twin-screw blowers are a new product developed in line with the market's demand for energy saving and environmental protection, utilizing advanced processing equipment. Compared to traditional blowers, they offer the following outstanding advantages:
Patented rotor winding design, offering higher efficiency, with potential energy savings of up to 20%.
2. Higher exhaust pressure, up to a maximum of 1.5 bar.
3. Low vibration, smooth operation.
4. Internal and external oil channels; no need for water cooling.
5. Anti-noise muffler, without sound-absorbing material, cleaner gas.
6. Self-tensioning belt design enhances transmission efficiency and facilitates maintenance.
