ROTOR ASSEMBLY FOR A ROTARY ATOMIZER

摘要

A rotor assembly (1) for a rotary atomizer is presented comprising a rotor (2) and at least one nozzle insert (3) that acts as a nozzle of the rotary atomizer. Rotor assembly (1) is characterized in that nozzle insert (3) is a porous plastic insert, preferably made of sintered porous Ultra High Molecular Weight Polyethylene with an average pore size smaller than 500 micron and a void volume between 30 and 80 percent. Rotor (2) can be disc shaped, and have a plurality of insert holders (5) in order to secure the position of porous plastic inserts (3).
