Suction line filter

Suction Line Filters – Compressor Protection Systems

Essential Contamination Defense for Refrigeration Circuits

High-efficiency filters designed to safeguard compressors from damaging particulates, moisture, and acids in refrigeration systems.

Key Features:

✓ Dual-action filtration – Captures solids and acids
✓ Low-pressure drop design maintains system efficiency
✓ Moisture-absorbing core (molecular sieve media)
✓ Wide refrigerant compatibility (R134a to R507)
✓ Replaceable core versions available

Technical Specifications:

• Connection Sizes: 3/8″ to 1-1/8″ SAE

• Pressure Rating: 500 PSI working pressure

• Temperature Range: -40°C to +120°C

• Filtration Grade: 20μm absolute

• Acid Capacity: 5mg KOH/g (standard)

Critical Applications:

✔ Post-burnout system recovery
✔ Cold room compressor protection
✔ Chiller plant preventative maintenance
✔ Pharmaceutical storage systems
✔ Commercial freezer installations
✔ Refrigerant retrofit procedures

Why Install Suction Filters?

• Prevents compressor wear from abrasives
• Neutralizes harmful acids from burnouts
• Maintains oil quality by removing contaminants
• Simplifies system cleanups after failures
• Protects expansion valves from blockages

Installation Guidelines:

• Install vertically in suction line

• Position downstream of accumulator

• Replace after 6 months or 2000 operating hours

• Use with liquid line filters for complete protection

Available with optional sight glasses and moisture indicators!
