Description
❄️ O&F FA-DT Series Accumulator: Technical Details
The FA-DT series is designed for installation in the suction line, protecting the compressor from liquid slugging and ensuring consistent oil return.
I. General Technical and Operational Data
| Parameter | Specification | Note |
| Max. Admissible Working Pressure | 2.8 MPa / 28 bar (Approx. 406 PSIg) | Pressure rating suitable for most low and medium-temperature systems. |
| Admissible Working Temperature | -10^C to +100^C (Standard range) | Suitable for a wide range of operating conditions. |
| Applicable Refrigerants | R134a, R22, R407c, R404a, R507a | Compatible with common HCFC and HFC refrigerants. |
| Connection Type | ODS (Outer Diameter Soldering/Brazing) | Ensures secure, welded connection into the copper suction line. |
| Installation Orientation | Vertical | Mandatory for the U-tube and gravity separation to function correctly. |
| Internal Mechanism | U-Tube with Metering Orifice | The core design feature for vapor separation and oil metering. |
II. Model-Specific Data (Capacity and Dimensions)
The FA-DT models are primarily differentiated by the suction line connection size, which corresponds to the compressor’s capacity.
| Model Number (Example) | Suction Line Size (ODS) | Suction Line Equivalent (mm) | Approximate Shell Diameter (mm) | Approximate Overall Height (mm) |
| FA-206 | 5/8″ | 16 mm | approx 102 | approx 280 |
| FA-207 | 7/8″ | 22 mm | approx 102 | approx 310 |
| FA-208 | 1-1/8″ | 28 mm | approx 127 | approx 350 |
| FA-209 | 1-3/8″ | 35 mm | approx 152 | approx 400 |
| FA-210 | 1-5/8″ | 42 mm | approx 165 | approx 450 |
| FA-221A | 2-1/8″ | 54 mm | approx 219 | approx 600 |
Note: The physical dimensions (Diameter and Height) increase significantly with the capacity to provide sufficient volume for liquid holdup.
