The AIRnet modular air piping system is made from lightweight, powder-coated aluminum tube and designed for easy, low-cost installation with a large selection of engineered polymer fittings. No special tools are required. The smooth, low friction inner surface of the aluminum pipe maintains a minimum pressure drop throughout the air distribution system. This allows compressors to work at lower operating pressures, reducing power consumption and operating costs. The non-corrosive properties of AIRnet maintain a constant air quality from compressor to site of use.
