Moisture –The Filter-Drier removes moisture from the refrigerant by absorbing and retaining it deep within the desiccant granules. The “CW” line ( New series) is designed for use with the polyester oils and features approximately twice the water capacity of a standard.

Foreign Matter – The Filter-Drier will filter out scale, solder, particles, carbon, sludge, dirt, or any other foreign matter with negligible pressure drop. Fine particles that would go through an ordinary strainer are removed down to the minimum size in one pass filtration. The large filtering area of the Filter-Drier core permits it to collect a large amount of dirt without plug up.

Acid – The Filter-Drier is unexcelled in acid removal ability. The hydrochloric, hydrofluoric, and various organic acids are absorbed and held by the desiccant in a manner similar to the absorption of moisture. Tests have demonstrated that the Filter-Drier will remove over 20 times as much acid as the desiccant used in most driers. This ability, along with its excellent ability to clean up the oil, is responsible for the excellent field performance in cleaning up severely contaminated systems.

Oil Sludge and Varnish – The Filter-Drier will filter out scale, solder, particles, carbon, sludge, dirt, or any other foreign matter with negligible pressure drop. Fine particles that would go through an ordinary strainer are removed down to the minimum size in one pass filtration. The large filtering area of the Filter-Drier core permits it to collect a large amount of dirt without plug up.

Special Application– A special “HH” core Filer-Drier is available to remove wax which frequently causes difficulty on low temperature Refrigerant 22 and 502 systems.

Remember - It’s not how much moisture you remove from a refrigeration system that counts, it’s how little moisture is left.
