• See the movie to witness the head to head test of the screw versus the lobe blower
  

The performance of the new ZS screw blower was tested against a tri-lobe blower by the TÜV, according to the international standard ISO 1217, edition4.
 
It was proven that the ZS is 23,8 percent more energy-efficient than a tri-lobe blower at 0,5 bar(e)/7 psig, and 39,7 percent at 0,9 bar(e)/13 psig.  The world-class efficiency of the ZS is mainly attributed to the superior screw technology.
