Since 1946 the name HAZEMAG has been linked with accomplished technology and workmanship of the highest order. Our dedication to the advancement of impactor design and control technology is easily found within our family of primary, secondary, tertiary and sand impactors. Within each of the over 110 HAZEMAG impactors to choose from, sits its heart - the rotor. The sucess of any impactor is highly influenced by the design, style and selection of the correct rotor. It is only fitting that HAZEMAG, the world's leader in impactor technology, offers a complete range of rotor designs and styles.
