  1. The dirty liquid pumped by the coolant pump is filtered when passing through the magnet, and the clean liquid is sent from the top of the main body to the outside of the main body.Chips and sludge are captured by the magnet part.
  2. Chips and sludge are able to be recovered at any time.Remove the clamp and packing, lift the handle, and remove the main body from the case.Sludge falls from the main body when the lever is pulled.
