When selecting from our Numatic range of Industrial Wet Vacuums the most important element is your preferred method of emptying the machine. These methods are denoted by the Suffix at the end of the model number.

DH, PH, AP? What They mean:

• DH – Dump hose, the wet vacuum is emptied of water by gravity. A large hose in diameter is connected to the vacuum at the base and then fed into a drain. Once the tap is open, the vacuum drains is drained of its contents.
• PH – Pump Hose, there is a pump that has to be manually operated by the user. When the vacuum is full the pump is switched on and the contents are pumped out into a drain or somewhere else that is safe to do so. The added bonus of a pump hose is the vacuum is capable of being emptied into something higher than the vacuum base.
• AP – Auto Pump, is when the vacuum is fitted with an auto-pump. An auto-pump on a vacuum means it can be drained while it is in operation. As a result you don’t have to stop to empty the contents. It is emptied while you work. The added advantage of an auto-pump vacuum like the Numatic WVD1800AP is the time and effort saved meaning increased productivity by the user(s).
