Threlaco 2-Pack Flow Filter Drier EK-083S for 1–5 Ton Heat Pumps & Refrigeration

Protect your refrigerant circuit with a proven two‑pack

Meet the Threlaco EK-083S flow filter drier, a 2‑pack designed to guard cooling and heating systems from moisture and particulates without compromising performance in typical HVAC setups. Each unit uses a 0.4 inch (10 mm) copper connection and a sweat inlet/outlet for flexible, reliable integration into liquid lines.

Core features at a glance

• Durable construction with an epoxy powder‑coated outer shell that resists corrosion and wear in challenging environments.
• Inner molecular sieve filter material actively absorbs moisture and traps contaminants from refrigerants.
• High pressure tolerance up to 4690 kPa, supporting safe operation in demanding applications.
• Unidirectional flow design ensures refrigerant moves through the filter in the intended direction for effective filtration.
• Compatible with a range of common refrigerants across cooling and heating scenarios.

Versatile installation and practical use

Easy to connect to refrigerant pipelines, the drier can be placed horizontally or vertically. When mounted vertically, it encourages top‑to‑bottom flow for optimal filtration, helping protect downstream components.

• 0.4 inch / 10 mm copper tube welded connections match standard fittings.
• Designed for systems from 1 to 5 tons, suitable for residential, light commercial, and small industrial setups.
• Two units per pack provide a convenient plug‑and‑play solution for maintenance or upgrades.

What’s in the box

You receive two flow refrigeration and drying filters built to withstand regular refrigerant cycles and environmental exposure, helping your cooling or heating system maintain steady performance.

Materials and reliability

The exterior epoxy coating delivers corrosion resistance, while the inner sieve helps reduce residual moisture and particulates. This combination supports consistent refrigerant quality across typical service life expectations.

Usage considerations

These driers are designed for use with various refrigerants in heat pumps, air conditioners, and refrigeration circuits. Actual outcomes depend on the overall system design, but including a dedicated flow drier can be a prudent maintenance step toward reliable operation.
