The EKZ‑083S (also referenced as EK‑083S) is an 8 cubic‑inch liquid line filter‑drier designed for commercial HVAC and refrigeration systems. It features:
A premium compacted bead construction with a 20 micron outlet pad, maximizing filtration efficiency. Compatibility with a broad range of refrigerants, including CFC, HCFC, and HFC types such as R‑12, R‑134a, R‑22, R‑404A, R‑407C, R‑410A, R‑500, R‑502, and R‑507. It’s also approved for use with POE oil, Durable steel shell construction with epoxy powder coating, resisting corrosion and physical shock. Connections are made of solid copper

Flow and capacity data (at 1 psi pressure drop):
R‑134a or R‑22 systems: 4.0–4.5 tons at 75 °F, rising to ~5.4 tons at elevated temps.
R‑410A: ~4.3 tons at 75 °F to ~5.5–6.3 tons at 125 °F.
R‑404A / R‑507: ~2.9 tons rising to ~4.8 tons depending on ΔT
Filtration-first design extends desiccant life and improves moisture extraction performance.
High capacity for moisture and acid, safeguarding system components & compressor oil.
Corrosion-resistant finish and shock-resistant shell improve reliability in field service.
Universal compatibility with most common refrigerants and oils, making it versatile for retrofit or service applications.
Ideal for residential or light commercial refrigeration and air conditioning systems using common refrigerants. Best suited for replacing or upgrading filter‑driers in systems sized up to ~5 tons (R‑410A) or ~5.5–6 tons (R‑22, R‑134a).
Ensure proper connection type matching: the EK‑083S uses 3/8″ ODF flared tubing; if your system uses SAE flare, consider the EK‑083 (SAE version) instead.
