Tired of swapping filters when changing from wet to dry pickup? Get yourself a CV. Numatic’s clever combi filter gives effective filtration when collecting both wet and dry debris so there is no need to switch, just wash the filter off when emptying the machine. The CV 900 has a single 1200W bypass motor and is available in 240v and 110v. Its’ 40 litre drum is made from Structofoam, Numatic’s virtually indestructable high impact plastic, for ultimate durability. This machine does not use bags. Numatic’s 570 and 900 wet and dry machines are the perfect industrial vacuum cleaners.
