FAQ
A1: The capacity refers to the molecular sieve desiccant weight, typically 10g, 15g, 20g, or 25g.
A2: The molecular sieve absorbs moisture and acid from the system, preventing compressor damage and extending system service life.
A3: KAK copper filter driers are compatible with CFC, HCFC, HFC, blends, and natural refrigerants (R22, R134a, R410A, R32, R404A, R507, R290, R600a).
A4: Yes, besides the standard 10g/15g/20g/25g, other capacities can be customized upon request.
