This machine is applied as an air lock installed under the dust removers, filters, etc. to discharge their contents.
-The machine is made of cast iron GG 25.
-The gap between rotor and cylinder is less than 0.1mm and over 0.07 mm creates the air lock that causes a smooth move of rotor and prevents rotor locking.
-Rotors work on permanently operating bearings (no lubricant needed).
