| Z-screw Fast and Easy Thermal Control Facilitates the Disposal of Waste Heat The waste heat temperature is reduced to only one-seventh of that in a conventional oil-free air compressor. This promises the ready disposal of waste heat at sufficiently low temperatures. The water-lubricated ZU air compressor runs at |
