At AERZEN, we also develop bulk vehicle blowers for installation in silo trucks and tankers, with extended pressure differentials reaching up to 1.5 bar. Cement manufacturers have the option of getting cement blowers with either a three-lobe or two-lobe rotor design.
Delta Hybrid is the perfect synthesis of positive displacement blower and screw compressor. Unlike the conventional positive displacement blower (max. 1,000 mbar), the innovative screw blower uses a new and unique 3+4 compressor profile, which is specially designed for low pressure applications up to 1,500 mbar. Delta Hybrid thus closes the gap in the previous machine mix and offers a wide range of services for precise design to meet the most diverse process requirements. The result is a new level of cost efficiency for compressed air applications.
In the two-lobe rotor design:
The robust three-lobe blower systems present three-lobe rotors and two cast-in pre-inlet channels in their discharge-sided cylinder section, minimizing the sound through pulsation reduction. These blower systems suit a broad range of challenging applications, including the oil-free conveying and compression of gases and air.
The blower comes in 22 different sizes, from GM 3 S to GM 1080 L. The blower cylinders in the GM 3 S up to the GM 400 L models are undivided while, from the GM 430 S models onwards, the cylinders are divided horizontally. The feet at the blowers are bolted on up to the GM 80 L, while those on larger sizes are cast on.
Four piston ring labyrinths seal the conveying chambers with oil singers at every shaft end. However, you can get four radial seal ring-piston labyrinth seals on request. A radial seal ring seals the blower’s driving shaft.
