Filter

With two decades as a trusted leader in refrigeration compressors and their critical components, ascompressors.com understands that a clean and contaminant-free refrigerant circuit is paramount to system longevity and efficiency. Filters and filter-driers are indispensable guardians of your refrigeration and AC systems, meticulously removing moisture, acid, and solid contaminants that can cause catastrophic damage to your compressor and other sensitive components. As your dedicated supplier, we offer a comprehensive range of high-quality filters designed for the rigorous demands of commercial and industrial cooling applications.

A filter's primary role is to protect the compressor and expansion valve from impurities. Moisture, if not removed, can combine with refrigerant to form corrosive acids, leading to motor winding damage and component failure. Solid particles, such as metallic shavings or debris from system wear, can clog expansion valves and score compressor internal parts. By maintaining refrigerant purity, filters ensure optimal system performance, reduce maintenance costs, and significantly extend the lifespan of your valuable equipment.

Core Filter Series & Key Products We Supply:

Our extensive inventory includes a variety of filters and filter-driers, carefully selected for their filtration efficiency, moisture absorption capacity, and robust construction. We focus on providing solutions that offer unparalleled protection and peace of mind:

• Liquid Line Filter-Driers: These are installed in the liquid line of the refrigeration system, typically after the condenser and before the expansion valve. They are the primary defense against moisture, acid, and solid contaminants. We offer models with various desiccant blends (e.g., molecular sieve, activated alumina) to optimize moisture absorption and acid removal for different refrigerants (e.g., HFC, HCFC, CFC, HFO). Key types include:

  • Hermetic Filter-Driers: Sealed, non-serviceable units for permanent installation.

  • Replaceable Core Filter-Driers: Featuring a reusable shell and replaceable desiccant cores, ideal for larger systems requiring periodic servicing.

• Suction Line Filters (Catch-All Filters): Positioned in the suction line before the compressor, these are crucial for protecting the compressor from large debris or contaminants that might be circulating, especially after a compressor burnout or system repair. We supply various sizes and filtration levels, including models designed for acid removal after a burnout.

• Strainers: While often integrated into filter-driers, standalone strainers are used to capture larger solid particles, preventing them from reaching sensitive components. These are common in larger industrial systems or at pump inlets.

• Oil Filters: For systems with oil separation and return lines (especially screw compressors), dedicated oil filters ensure the lubricating oil remains clean and free of particulate matter, which is critical for compressor bearing and rotor longevity.

We ensure our filter offerings come in a range of connection types (solder, flare), sizes, and capacities to match diverse system tonnage requirements and installation configurations. Many of our filter-drier products also feature a sight glass with a moisture indicator, allowing technicians to visually monitor refrigerant flow and the presence of moisture, signaling when a drier replacement might be needed.

Essential Applications & Industries for Our Filters:

The uncompromising purity and protection provided by our high-quality filters are vital across a broad spectrum of commercial and industrial cooling applications:

• Commercial Refrigeration: Supermarket display cases, walk-in coolers, reach-in freezers, and beverage chillers, ensuring food safety and equipment reliability.

• Industrial Refrigeration: Large cold storage warehouses, food processing plants, breweries, and chemical industries, where system uptime and product integrity are critical.

• HVAC Systems: Central air conditioning units, chillers, and large air handling units for commercial and industrial buildings, optimizing efficiency and preventing costly breakdowns.

• Transport Refrigeration: Reefer trucks, containers, and railway cars, where robust filtration is essential to withstand harsh conditions and protect perishable goods.

• System Start-ups & Burnout Cleanups: Absolutely crucial during initial system charging and especially after a compressor burnout to meticulously remove all contaminants and prevent repeat failures.
