The Kenair Dust Vac Kit comprises a 360ml cartridge of Kenair, a reusable actuator valve and a Dust Vac attachment. The Dust Vac attachment plugs onto the actuator valve and converts it to vacuum mode. The pick up tube on the Dust Vac has a soft end to assist in preventing scratching delicate surfaces. It is particularly useful for cleaning areas where air dusters are not recommended, such as digital equipment. This versatile system allows the user to safely blow or vacuum away foreign particles from a wide variety of equipment. The can contains a CFC/HCFC free gas that fully complies with all EU regulations. Kenair is widely used in the photographic, movie, electronics, computer and service industries. It emits a powerful controllable jet that will blow dust, fluff, lint, grit and other unwanted particles from all types of surfaces.
