More about Class Zero

Low noise levels

Compressed air solutions with low noise levels. Rain canopy available for outdoor use. No need for additional investment in extra buildings or sound reducing facilities.

Setting a new energy-efficient standard

In wastewater treatment plants, blower systems consume up to 70% of the total energy. We can help reduce your energy costs. As the first manufacturer to introduce the oil-free screw technology in wastewater treatment, we are committed to lower you energy usage significantly.

Reducing the carbon footprint of wastewater treatment

The demand for water increases while resources are reduced: efficient water management becomes increasingly important. Our blowers are completely free of oil, which is of critical importance. Contamination is just not acceptable when re-using water for other applications or keeping bacteria and microorganisms in sludge processes alive.

Global installed base and aftermarket service

We service thousands of low pressure compressed air installations throughout the world. Backed by a global and highly efficient logistics organization we ensure your equipment is always working at peak efficiency.

Municipal wastewater treatment plants benefits from energy-efficient ZS screw blower

In conventional wastewater activated sludge plants, millions of bacteria feed on organic waste, breaking it up into carbon dioxide, nitrogen gas and water. Because the bacteria need oxygen, large amounts of air are blown in the aeration tanks. The aeration blower system accounts for up to 70 percent of the energy usage in a typical biological wastewater treatment plant. To permit energy optimisation and to substantially reduce energy bills in these continuously operating plants, Atlas Copco's innovative air blowers incorporate the latest energy efficient design and technologies.
