Manual reference 3A4792. Part of GRACO’s direct drive agitator family with various mount and blade configurations available. Part has CE marking with Ex certification (II 1/2 G Ex h IIB T4 Ga/Gb, CML 24ATEX6027X, IECEx CML 24.0020X, temperature range 0°C Tamb 50°C) Installs in container cover by screwing helix (5) through drum bung hole and screwing agitator housing (3) into the bung hole. Requires positioning air motor so air line easily attaches to air regulator inlet. Keep agitator tightly mounted to drum bung to prevent damage to threads from vibration.
