• Quieter for greater flexibility

- Efficiency‑optimized airend: The airend with integrated, fully enclosed gears (depending on the model) reduces energy consumption thanks to minimized internal pressure losses. The flow‑optimized internal compression process ensures a quiet, disturbance‑free sound level. Thanks to the transmission gradation, all output ranges and pressures can be variably controlled.

- Easy access principle for simple maintenance: All sound‑insulating panels on the S‑4 can be removed for easy access to all components in next to no time. Access is limited to two sides, and thanks to intelligent details, such as the drawer principle for oil and air coolers, easy maintenance is guaranteed.

- Longevity thanks to intelligent design: Generously sized components ensure low internal pressure losses and maximum efficiency. Our completely maintenance‑free integrateDrive is enclosed and lubricated with the oil circulation of the compressor. A minimum pressure non‑return valve and a suction regulator also ensure a gentle, non‑wearing startup. This keeps pressure losses to a minimum, and the compressor is vented after switching off.

- Quieter for greater flexibility: Every design feature has been developed with maximum noise reduction in mind – from the low‑rotating airends and radial fans to the choice of innovative recycling material for sound insulation: It is environmentally friendly, non‑flammable and boasts a high adsorption factor. Result: the quietest screw compressors in their class and maximum installation flexibility.
