Model NVD/NV
As it is a water seal type, condensation drops of water may form and get mixed into the suction valve and air.Other than the bearing and ground portion, there is no mechanical exposure, making it easy to operate and maintain.
Compact and light-weight requiring no installation space.
If connected to an exclusive water tank, it will automatically direct water to the vacuum pump, thus reducing noise pollution.（NV-type)
