Hermetic filter driers CERTIFIED BY UNDERWRITERS LABORATORIES INC.
For refrigeration plants that use HCFC, HFC or HFO Refrigerants
The filters, shown in this leaflet, are designed for installation on commercial refrigerating systems and on civil and industrial conditioning plants. Filters series DF2 and series DF3 have been developed for specific installations on refrigerating systems using HFC refrigerant fluids, particularly R134a , R404A , R407C , R410A and R507 mixed with POE lubricants. In spite of this, the new block may be successfully used also in refrigerating systems using the old CFC or HCFC refrigerant fluids, mixed with mineral lubricants.
