<p>A light-weight, readily replaceable filter-drier (20) for use in a refrigerant recycling device comprising a long, narrow body (22) containing a closely packed desiccant material (28) that substantially occupies the entire volume of the body. The desiccant (28) may be comprised of 100 percent molecular sieve or any combination of desiccants and/or other adsorbent materials that are required to achieve the desired degree of refrigerant purity. Filters (36) are located at either end of the body which are biased by a spring member support (38) and contain the desiccant material (28) within the body (22). Standard fluid fittings (30) close the ends of the filter-drier (20) and enable the device to be easily and quickly installed and removed in the refrigerant recycling device. In a preferred configuration (50), multiple filter-driers (52,54) are connected in series and have a moisture indicator (56) located therebetween. <IMAGE></p> |
