Smart Air Injection

SAI Smart Air Injection

Long distance pumping

Smart Air Injection (SAI) is a customized package unit with many varied applications. The innovative combination of progressive cavity pump and compressed air conveying results in a low-pressure level in the conveying pipeline, thus extending the service life and lowering investment and operating costs. In the environmental sector, SAI transports sewage sludge up to 1,000 meters by means of compressed air and lubricant injections. In the food industry especially in breweries and distilleries, SAI conveys hop and malt spent grains by means of controlled, compressed air pulses.
