DF, magnetic, brass contaminant separator with insulation. It consists in the retention and separation of all heavy solid contaminants present in the hydraulic circuit due to the extinction of their velocity, which facilitates their deposition on the surface of the synthetic filter mesh. Subsequently, this allows them to fall into the lower part of the device (collection bowl), which acts as a separation chamber. Dirt separators are supplied complete with an insulating housing made of PE-X, which guarantees minimization of heat loss.
