1, Roots blower for the characteristics of the output of the gas volume, constant pressure (want to compressor than the air pressure is a lot smaller), the equipment for the design of the 24-hour continuous operation can be non-stop long time use. Roots blower commonly used pressure in 20 ~ 100KPa (0.2 ~ 1.0bar), applicable to sewage treatment, if the depth of water in the 2m ~ 10m or so.
2, the compressor is characterized by air compressed into high-pressure gas use (pressure within 8bar, much higher than the Roots drum machine, but the gas volume is small, used for sewage aeration, the need to add storage tanks, and post-processing de-oiled equipment for use after treatment), generally intermittent work, such as over a long period of time in continuous use, will cause motor overheating, component damage fast (high-quality compressor is another). (High-quality compressor is another matter, equipment costs are in the tens of thousands, millions of).
3, so according to the design of the equipment itself to see the applicability of the Roots blower is more suitable for sewage treatment, such as continuous gas supply environment such as electroplating production mixing, aquaculture and so on. Compressor is more suitable for intermittent gas, pressure requirements of the environment is very high, commonly used in pneumatic equipment drive.
