The Mark X 240 Volt is Graco's largest electric airless/texture unit.With nearly double the output of the Mark V, it's a great choice for serious professional contractors who take advantage of the 240 volt power available at the construction site or with a generator. A true powerhouse, it can easily spray skim coat in a Level 5 finish, and drywall mud in an orange peel, splatter or knockdown finish. It can even apply the whole range of primers and paints.
