The RS PRO 400ml butane air duster is a non-invertible flammable spray duster. The ERFD4000 safely removes dust and airborne contamination. The air duster is especially useful for the removal of debris and contaminants from delicate and inaccessible areas of electrical and electronic equipment. Make sure to use the spray duster either in a vertical position or at an angle of no greater than 60° to avoid freezing. Avoid spraying it directly onto any live equipment, as it is a flammable propellant.
