Double Tooth Compressors: Cool Name, Even Cooler Technology

At Atlas Copco, we take innovation seriously. And when technology can be improved, we go for it.

You may already be familiar with Atlas Copco’s ZR/ZT series of oil-free rotary tooth compressors. This series was developed especially for applications demanding the highest level of purity, such as manufacturing processes in the pharmaceutical, food and beverage and critical electronics industries.

Introduced in 2002, the ZR/ZT series incorporated a brand new tooth compression technology: double tooth configuration. Unlike the single tooth element, the compression rotor in the ZR/ZT series is symmetrical, dynamically balancing the rotor and facilitating more efficient compression.

Behind the increased efficiency lies a range of advanced technologies including two-stage compression. First, atmospheric air is drawn through the inlet port into the compression chamber. Air then becomes trapped between the teeth of the male and female rotors. As the rotors turn toward each other, the available space for air decreases, and the pressure increases. Finally, one rotor exposes the outlet port and the compressed air is released into the system.

When combined with the other innovative technology housed inside the ZR/ZT machine—the integrated Variable Speed Drive (VSD) converter, integrated dryer, combination filter and silencer, electronic water drains, a sound insulated canopy, even the advanced Elektronikon control and monitoring system—the double tooth technology helps produce maximized efficiency and absolute air purity for your manufacturing process.
