Overview
The SMC NAM400 mist separator is a pneumatic filtration component designed to remove oil mist, aerosol particles, and contaminants from compressed air systems. Built by SMC, the world’s largest manufacturer of pneumatic automation products, this unit separates and absorbs fine oil particles to deliver cleaner air downstream. Used in metalworking shops, CNC operations, and manufacturing facilities where air quality directly impacts tool life and product quality.
