Pneumatic coolers and air knives convert compressed air into fast moving, focused air which serves to cool, clean, or dry materials. Air knives generate a linear sheet of air to sweep across conveyed items. Air wipes are cylindrical passages for extruded pipe, tubing, or cable to travel through as they are swept by a 360 degree sheet of centrally directed air. Air amplifiers ventilate or blow large volumes of air in a localized work area. Cold air guns blow finely focused streams of air directly onto workpieces. Vortex tubes blow extremely cold air to rapidly reduce temperatures in hot production environments. Cabinet and enclosure vortex coolers mount directly to electrical enclosures to cool sensitive electronics.
