Normal DVJ applications have a vacuum on the inlet and atmospheric pressure on the discharge jet port connections. One jet port must have a full size inlet silencer with no valve or other restrictions. The other port must have the metal cover plate installed.

DVJ Blowers are supplied with internal abradable graphite-based coating. The effect of coating is to close up internal clearances, decreasing slip and increasing flow and efficiency at any given speed. Machines with internal abradable coating are for use with clean, dry air only.
