Numatic WV1800DH Industrial Wet Vac - This wet only industrial vacuum has a huge 70 litre capacity. The 1200W motor produces an impressive 38 litres/second airflow and the outer shell is constructed from high impact Structofoam. This incredibly durable plastic is the ideal material for tough, rugged industrial and commercial vacuum cleaners because it is as close to indestructible as you can get. The drum of the machine has two large wheels at the rear to provide balance and stability when on the move and the two front caster wheels maintain maximum manoeuvrability. The WV1800DH features a specialised ‘trash filter basket' that captures any objects such as cigarette ends or wrappers, stopping them from entering the machine. When emptying the machine you simply use the ‘Dump Hose' function. Wheel the unit over a drain or similar waste water receptacle and simply pick up the dump hose, remove the stopper and place the hose in the receptacle. The water inside the drum then flows out of the machine and into the drain. Simple, quick and mess free emptying has never been easier.
