Oil-free screw compressors, water injection
Ideal for industrial applications, oil-free screw compressors WIS are characterized by economical and environmental sustainability. These compressors allow savings of up to 35% thanks to the inverter technology. Besides, they produce pure air respecting the level of class O certified by ISO 8573-1, which is the purest level recognized. Besides, the absence of oil drastically reduces the maintenance services, without needing any filter solution and oil changes: this contributes to reducing the operating costs significatively.
Equipped with a sound-absorbing cover and, thus, adapt to several workspaces, oil-free compressors WIS are highly reliable: the motor isn’t stressed thanks to the gradual start, and the components are based on anti-corrosion materials. The drastic reduction of sudden breaks makes this compressor a long-lasting investment.
