Cores for different applications:
48-DC / 48 AA: Core for high humidity absorption liquid line, applied when maintaining systems with high concentration of
water (water condenser leak, low temperature component blockage)
48-DA: Core for acid cleaning
48-FE / 48-F: For cleaning impurities in the suction line.
48-AN / Normal absorption (humidity + acidity) applied in the prevention of systems in general.
