Description

Copeland Emerson ALCO ASF Suction Line Filter Drier

Hermetic suction-line filtration designed to help protect refrigeration compressors from dirt and solid contaminants circulating through the refrigeration system.

ASF Series Suction Line 40 Micron Filtration Compressor Protection Hermetic Design

Protect Your Compressor from Solid Contaminants

The Copeland Emerson ALCO ASF Series Suction Line Filter is specifically designed to help protect refrigeration compressors from dirt and solid contaminants returning through the suction line.

With filtration down to 40 microns, the ASF provides an additional level of protection between the evaporator and compressor, helping prevent unwanted particles from circulating into critical compressor components.

Its hermetic construction, solid copper connections and corrosion-resistant finish make the ASF suitable for commercial refrigeration, air-conditioning, cold-room and freezer applications.

Why Choose Copeland ASF?

🛡 Compressor Protection Specifically designed to help protect the compressor against dirt and solid contaminants returning through the suction line.

🔍 40 Micron Filtration Provides fine filtration of solid contaminants before the refrigerant returns to the compressor.

📊 Pressure Access Most ASF models feature service access valves that allow technicians to check pressure drop across the filter.

🔩 Solid Copper Connections Copper connections provide convenient installation into refrigeration piping.

🛡 Corrosion Resistant Finish Epoxy powder coating helps protect the external shell in refrigeration environments.

⚙ Wide Size Range Available in multiple unit sizes and connections for small through larger commercial refrigeration applications.

How to Read an ASF Model Number

Example: ASF 50S9VV

ASF = Hermetic Suction Line Filter Series
50 = 50 cubic-inch unit size
S = ODF solder connection
9 = Connection size in 1/8" increments → 9/8" = 1-1/8"
VV = Dual access valves

Connection Code:
S = ODF / Solder
F = SAE / Flare
V = Single access valve
VV = Dual access valves

How Does the ASF Suction Line Filter Work?

① Suction Gas Enters Refrigerant returning from the evaporator enters the ASF through the suction piping.

② Contaminants Are Filtered The internal filtration system captures dirt and solid particles down to approximately 40 microns.

③ Cleaner Refrigerant Returns Filtered suction gas continues toward the compressor, helping protect critical compressor components.

ASF Suction Filter – What Is Its Main Function?

It is important to select the correct Copeland suction-line product according to the contamination problem.

🔵 ASF Series Main focus: dirt and solid contaminant filtration. Ideal when compressor protection from solid particles is the primary requirement.

🟢 Premium Suction Filter Driers Other Copeland suction-line filter-drier families are available when the system requires stronger moisture, acid and contamination removal, such as after certain system failures or major service work.

Important: Do not assume every suction-line filter has the same function. The ASF is specifically described by Copeland as a filter for protecting the compressor from dirt and solid contaminants.

Why Is Suction Line Filtration Important?

Solid contamination left inside a refrigeration system can circulate with the refrigerant and oil. If these particles reach the compressor, they may contribute to wear, blockage and other reliability problems.

Installing the appropriate suction-line filter provides an additional barrier between the refrigeration circuit and the compressor.

Simple Selling Point:

Catch the dirt before it reaches the compressor.

Built-In Pressure Access for Easier Servicing

Most ASF models include access valves that allow technicians to take pressure readings across the filter.

Comparing inlet and outlet pressure can help technicians evaluate pressure drop and determine whether contamination may be restricting refrigerant flow through the filter.

VV = Dual Access Valves

Pressure Reading Before Filter → ASF Filter → Pressure Reading After Filter

How to Select the Correct ASF Model

1. Suction Line Size Select a connection size compatible with the designed suction piping.

2. System Capacity Check filter capacity against the refrigeration system operating condition.

3. Refrigerant Verify suitability for the refrigerant and system application.

4. Pressure Drop Correct sizing is particularly important on a suction line to avoid excessive pressure loss.

5. Connection Type Most ASF models use ODF solder connections; selected SAE flare models are also available.

6. Access Requirement Select the appropriate access-valve configuration when pressure-drop monitoring is required.

Selection Reminder: Do not select an ASF only according to the pipe connection size. For example, ASF 28S9VV and ASF 50S9VV both use a 1-1/8" connection, but they have different unit sizes.
