SMC NAF811-N14 Pneumatic Filter

SMC NAF811-N14 Pneumatic Filter is a large-flow air filter designed for compressed-air lines. It features 1.5" NPT port connections and a maximum operating pressure of 1.0 MPa (approximately 145 psi), aligning with the higher-flow requirements of SMC's AF800/AF900 series of large-flow filters. This model sits within the AF811-N14 family, a configuration group seen in distributor catalogs, with examples such as NAF811-N14-127-40 illustrating the common variant under this part number. The unit's function is to remove particulates from incoming compressed air to protect downstream pneumatic components from contamination, supporting reliable operation of actuators and valves in systems with elevated airflow demands. With its 1.5" NPT connections and 1.0 MPa rating, this filter provides a straightforward option for replacing or upgrading air filtration in industrial equipment that requires clean, high-flow air. Catalog references indicate the N14 suffix denotes a specific configuration within the AF811-N14 family, with items like NAF811-N14-127-40 appearing in listings.
