Description
ZR & ZT Oil-free rotary tooth air compressors
Our oil-free rotary tooth compressors provide clean, oil-free compressed air using in-house designed and developed rotary tooth elements.
In 2025, we celebrate 45 years of pioneering oil-free rotary tooth technology. This solution stands out in its power range, boasting exceptional efficiency, remarkable operational flexibility, and a compact footprint.
The ZR & ZT compressors are utilized across a diverse range of industries that demand exceptional compressed air quality standards, including but not limited to food & beverage, pharmaceuticals, automotive, medical, textiles, power generation, chemicals, and batteries.
The key difference between ZR and ZT compressors is their cooling method. ZR compressors use water to cool the compressed air, while ZT compressors utilize air for cooling.
