Overview
The SMC AFF22C-N06BC-T is a main line filter from SMC’s proven AFF Series, designed as the first stage in any compressed air purification scheme. This coarse 3 micron filter removes foreign matter, water droplets, and oil mist to protect downstream dryers and extend the life of more precise filtration stages. The unit features a metal bowl construction, 3/4 NPT female ports, and an automatic normally-closed drain valve—ideal for continuous industrial automation and pneumatic control applications.
