With KAESER’s SIGMA profile rotary screw blowers, efficiency is more than just a promise. As ready-to-use, plug-and-play solutions, these low-maintenance blower systems offer exceptional cost-effectiveness at the touch of a button. Furthermore, the rotary screw blowers are designed to be particularly space-saving, easily remotely and independently controlled, and are Industry 4.0 compatible.

The low energy consumption and continuous operation of KAESER rotary screw technology pay off in municipal and industrial wastewater treatment, flotation and fluidization, and fermentation processes.

Performance data:

7.5 kW to 250 kW
Flow rate from 3 to 160 m³/min
Pressure drop from 300 to 1100 mbar

Your benefits

Maximum efficiency
KAESER rotary screw blowers are highly efficient across a wide flow rate range. The outstanding efficiency enables savings of up to 35 percent compared to conventional blowers.
Real-time operating and status data
The integrated SIGMA CONTROL 2 controller ensures efficient control and monitoring of operating and status data in real time. The diverse communication channels make conducting an energy audit according to ISO 5001 a breeze.
Low installation costs
The ready-to-connect blowers are fully equipped with sensors and emergency stop switches, oil-filled, and certified. This reduces effort and costs during planning, construction, documentation, and commissioning.
KAESER rotary screw blowers also master the balancing act
between optimal damping of structure-borne and fluid-borne noise and optimal cooling of the blower block
including the drive motor and cool intake air.
Long-term reliability
This includes
robust rotor bearings, solid power transmission, drive motors dimensioned to meet requirements, torsion-free
soundproof housings with well-designed cooling air flow,
SIGMA CONTROL 2 machine control for efficient,
safe operation, and much more…
