FAQ

Q1: What is the capacity of the copper filter drier?

A1: The capacity refers to the molecular sieve desiccant weight, typically 10g, 15g, 20g, or 25g.

Q2: What is the function of the molecular sieve inside the filter drier?

A2: The molecular sieve absorbs moisture and acid from the system, preventing compressor damage and extending system service life.

Q3: What refrigerants are compatible?

A3: KAK copper filter driers are compatible with CFC, HCFC, HFC, blends, and natural refrigerants (R22, R134a, R410A, R32, R404A, R507, R290, R600a).

Q4: Can the molecular sieve weight be customized?

A4: Yes, besides the standard 10g/15g/20g/25g, other capacities can be customized upon request.
