Carrier SF-4811-T Suction Line Filter 1-3/8" ODF Bi-Directional with Access Valve

The Carrier SF-4811-T is a 1-3/8" ODF suction line filter designed to protect refrigeration and HVAC compressors from system contaminants including metal chips, foreign particles, and oxides that can travel through the suction line and cause motor burnouts. This bi-directional suction filter features a 48 sq. in. filter surface area and is compatible with a wide range of refrigerants including R-12, R-22, R-134A, R-404A, R-407C, R-502, and R-507.

Key Features:

• Bi-directional bypass relief feature — when flow is in one direction, the bypass relief is active and opens slightly if pressure drop becomes excessive, maintaining sufficient gas flow and protecting the hermetic motor from overheating
• Access valve included ("-T" suffix) — the built-in access valve allows technicians to take pressure drop readings for system diagnostics; operational when the bypass feature is inactive
• 1-3/8" x 1-3/8" ODF solder connections — compatible with all standard brazing alloys for secure, leak-free installation
• 48 sq. in. filter surface area with 18.4-ton flow capacity for minimal restriction in large systems
• Low pressure drop full-flow design prevents unnecessary system load
• 25-micron filtration effectively captures fine contaminant particles
• Must be installed between the evaporator outlet and the suction-side separator or compressor; in reversible systems, install between the 4-way valve and the suction shut-off valve

This suction filter measures 13.10" overall length with a 3.00" OD body and weighs approximately 3.5 lbs. Also referenced as part number 800008. Cross-references: SF4811T, SF-4811T.
