Overview
The SMC AFF22 XR filter element is a high-capacity replacement cartridge designed for SMC AFF22 main line compressed air filter systems. As a surplus unit in new condition without original packaging, it offers the same performance specifications as factory-new replacements at a lower cost. This coalescing filter element effectively removes oil, water vapor, and particulate contaminants from pneumatic lines, protecting downstream equipment and extending the service life of precision filters and pneumatic components.
Key Features
- Removes water, oil vapor & other contaminants down to 5 microns
- Maximum operating pressure: 145 PSI (1.0 MPa); Minimum operating pressure: 7.25 PSI (0.05 MPa)
- Operates at 41°F (5°C) to 140°F (60°C)
- 1.3 times increased capacity over old AF models
- Easy slide-in/slide-out replacement—no special tools required
- Approximately 2-year service life depending on operating conditions
Technical Specifications
Filtration specifications, operating conditions, and maintenance intervals are critical for system reliability. The AFF22 element is engineered to handle demanding pneumatic applications with robust contaminant removal.
Typical Applications
- Pre-filtration stage for refrigerated dryers to avoid fouling of the dryer’s heat exchanger
- First stage in air purification schemes; removes foreign matter and droplets to protect downstream dryers and extend the life of more precise filters
- Industrial pneumatic systems requiring clean, dry compressed air
- Manufacturing environments with oil-lubricated compressors
- Any application where water and oil contamination must be minimized
