BS-DH Series Oil Free Screw Blower

The BS high-pressure oil-free screw blower innovatively designed by Gardner Denver is based on Gardner Denver' full understanding of process conditions, combined with rich experience in unit design and system operation, combining traditional products with innovative technologies. It can provide clean and oil-free food grade compressed air in fermentation, pneumatic conveying and other process flows in the food and beverage, pharmaceutical and other industries, ensuring the production of high-quality products. BS high-pressure oil-free screw blower has a maximum pressure of 2.5 bar (g) and a maximum air volume of 9300m3/h. The flow rate can be adjusted within the range of 30% -100%

·Efficient and reliable air end: using professional oil-free screw technology, highly integrated design, integrated oil tank/gearbox/oil pump/oil filter, etc. the blower has compact structure and excellent performance.

·Automatic opening and closing of intake valve: When the end-user does not use air or uses very little air, the intake valve will unload and close, reduce or even stop air production, avoid unit overload caused by pressure rise on the air side. Compared with the traditional method of adjusting exhaust flow or pressure with safety valves or overflow valves on the exhaust side of fans, it is more energy-saving, environmentally friendly, safe and reliable.

·Intelligent controller: Real time monitoring of blower operation status, capable of implementing IoT management such as fault warning and cloud storage.

·Low noise: patented design muffler, long-lasting use, reduces pollution. Avoiding the situation of long-term use that may cause dust and other impurities to contaminate pipelines and air when using a resistive muffler, the noise reduction is stronger. It has a good noise reduction effect on mid to low frequency noise.

·Lubricating oil cooler:

-Water cooler: Shell and tube cooler (with stainless steel tubes inside) made of stainless steel tubes, which are more resistant to high temperatures. At the same time, it has lower requirements for water quality and can be applied to hard cooling water.

-Air cooler: Aluminum plate fins, compact structure, easy to use.
