Spraying Systems has recently introduced its new line of air knives into South Africa. The comprehensive Windjet line of low flow air knives convert compressed air into high velocity air streams that significantly increase blow-off and drying efficiencies, while simultaneously reducing energy costs. Windjet compressed air products require minimal maintenance and operate at low noise levels that will not exceed 69 dBA for most applications.
Windjet low flow air knives use a thin slotted orifice across the length of the knife to create a uniform sheet of air. A secondary supply of air is entrained along the edge of the knife to generate optimal precision and velocity. This technology significantly minimises the use of compressed air and the energy costs that come along with it, while simultaneously delivering a hard-hitting force that maintains a highly uniform and constant air stream. Low flow air knives are suitable for applications that have existing compressed air sources in place, but also have limited mounting space and cannot handle any increases in air temperature.
Easy to install, compressed air knives feature an inlet connection of 1/4" NPT or 1/4" BSPT, standard shims installed at 5,08 microns (0,002"), additional shim sizes are available, which allow the user to customise the air stream for their application. Windjet low flow air knives come in 76, 152, 305, 457, and 610 mm lengths and are available in both aluminium and stainless steel finishes. Also available are Windjet low flow air knives kits containing shim sets, filters and a pressure regulator and gauge, all sized according to the length of knife being used.
