A blow-off gun is provided having a static eliminator having a gas inlet end and a gas outlet end. A removable hollow fiber filter is retained in and extends into the gas inlet end of the static eliminator. The hollow fiber filter communicates with a supply of gas through a handle portion of the gun. Located within the handle portion is a valve and trigger assembly, the valve being provided with a pin hole to supply a constant positive flow of gas, thereby to prevent backflow of ambient air into the gun.
