Product Description

Alco suction filter cores (F-48) and desiccant blocks (D-48, UK-48, W-48, H-100) fit most competitive shell type filter-driers. These filter-drier blocks protect the compressor from soluble and solid contaminants. To ensure efficient clean-up results, they feature exceptional acid and wax removal capacities, plus superior moisture pickup.


  • Highest water capacity rating on the market today, thus keeping flow rates up together with filtration and system capacity to its optimum
  • Exceptional acid capacities for normal system protection or to effectively clean-up following a compressor burnout
  • Wax removal capabilities, if desired, for low temperature applications, or for complete clean-up following a compressor burnout (W Series)
  • UK-48 Special Features:
    • A balance of high water/acid capacity (75% molecular sieve/25% activated alumina) to keep HFC/POE systems at optimum conditions
    • Perfect for new refrigerants, POE oils and retrofit guidelines
    • Desiccant blend protects POE additives
    • 20 micron filtration reduces sludge caused by POE oils
    • Complies with Copeland’s recommendations for filter-driers on POE/HFC systems
