MC-21 Series Air Filter Regulator 
 MC-21 series air filter regulator is factory main air pipeline supply pressure to the pressure value of the locator and control devices required for stable device. 
 - Regardless of the input pressure and flow fluctuations, always maintain a stable output pressure. 
 - Light weight, small size, easy installation and maintenance. 
 - Filter a minimum of 3 micron particles. 
 - If the output pressure is higher than the set pressure is automatically discharged to the atmosphere to maintain a stable output pressure.
