MOLDED CORE FILTER DRIER - Sintered Block, 20-Micron, Low Pressure Drop
Six core advantages that keep your refrigeration system protected around the clock
Small spherical desiccant beads are high-pressure sintered into one solid block that resists powdering and lasts longer.
Traps metal chips, oxide scale and welding slag to protect the expansion valve and compressor.
The optimized flow path minimizes pressure loss while maintaining full filtration performance.
Available with ODF welded or SAE threaded connections and TP2 copper stubs for quick installation.
Compatible with R-12, R-134a, R-22, R-404A, R-410A, R-502 and more.
Maximum working pressure of 2.9MPa for safe medium- and high-pressure operation.
