Considering installing your compressor outside? Think again. The temptation to save space may sound enticing, but in the long haul, it will cost you.

Turbowin’s WH-o Series is an outdoor-type turbo compressor that can perfectly withstand rainwater, snow, salt, and various other hazards in a working environment where an independent compressor room cannot be installed. Especially, WH-o Series has international certifications of IEC motor protection grade IP55 and IP65 in all parts including structure, material, and painting in both enclosure and package, therefore it can be completely protected from any fine dust (dust-tight) and water jets pouring in all directions. In addition, Turbowin’s dual cooling system plays a decisive role in stably operating the outdoor turbo compressor without a separate cooling device even at high external temperatures..
