Pyronics 4201-1012ADC Standard Air Ductors 1-1/2" with Needle Valve & Gauge

Air-Ductors are useful for supplying large volumes of air at pressures of 1 psig or less when high-pressure air is available at steady pressure. Because Hi-Pressure Air is relatively costly, it usually is less expensive to use a blower if the air requirements are continuous. However, for occasional use or where excess compressed air is already available, Air-Ductors are initially less costly and very easy to install.

Air-Ductors are particularly useful for supplying the combustion air requirements of a single Flomixer or group of burners. No valves or blast gates should be used between the Air-Ductor and the Mixer or Mixers it is supplying. If volume controls, either manual or automatic, are required, they should be placed in the high-pressure air supply.
