An apparatus separates liquid, gas and solid components of a mixture in a fluid system. An inlet for receiving the mixture opens into a separation chamber tangentially with a cylindrical side wall and a gas outlet has an opening in a first end wall adjacent the inlet to allow gas to exit the separator. A fluid outlet is located in an opposing second end wall. A debris passage extends through the cylindrical side wall and oriented so that the radial velocity of the particles within the separation chamber directs the particles through the debris passage. The debris passage leads to a particle collection chamber in which the particles accumulate. Unlike prior separators that relied on the tangential velocity of the particles, the present apparatus utilizes the greater radial velocity to drive the particles from the separation chamber into the particle collection chamber.
