DOF Double Oil Filters

Oil filters clean the oil in the refrigeration circuit. Double oil filters are designed to allow the change of the filter elements without interrupting operation.

AWP double oil filters enable the filter elements to be replaced without interrupting the system’s operation. The filter elements are made of rustproof woven metal mesh resp. paper. The size selection depends on the flow rate and the viscosity of the oil. AWP double oil filters are suitable for installation in the oil circulation of industrial refrigeration systems and are maintenance-free.
