Question 1

What is the difference between bidirectional and unidirectional filter driers?

Accepted Answer

Bidirectional filter driers like the BFK series can be installed in any flow direction, making them suitable for heat pump systems where refrigerant flow reverses. Unidirectional filter driers like the DFS series are optimized for one-way flow and provide superior moisture removal in standard AC and refrigeration liquid lines.

Question 2

Why does the DFS unidirectional filter drier use 100% 3A molecular sieve?

Accepted Answer

The DFS series uses 100% 3A molecular sieve instead of a mixed core, providing superior moisture adsorption capacity for applications where water removal is the primary concern. It covers ports from 1/4 inch to 3/4 inch with SAE flare connections and 25μm filter fineness.

Question 3

What is the maximum working pressure for the DFS unidirectional filter drier?

Accepted Answer

The DFS series is rated for MWP 45 bar (4.5 MPa) and operates at temperatures from −40 °C to +120 °C. The unidirectional design with 100% 3A molecular sieve provides optimal moisture removal for HCFC and HFC refrigeration systems.
