Overview
The SMC AFF22C-N06BC-T main line filter is a compact, high-capacity pneumatic filter engineered to protect downstream equipment and extend system service life. As the first stage in a compressed air purification scheme, this filter removes particulates, oil mist, and liquid water droplets, improving dryer function and preventing equipment malfunction. The metal bowl construction with sight glass provides visual inspection of filter saturation.
Key Features
- 3 µm particulate filtration with 99% efficiency
