- ADC-自吸式混合器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.
The Selection Table shows the approximate volume of low-pressure air (1 psig) that various sizes of Air-Ductors will deliver.
It also shows the high-pressure air orifice size to be used with
various inlet air pressures. When operating at capacities shown
and 1 psig delivery pressure, about 25 - 35of the total delivered
air will be high-pressure air (measured on a free basis). See pages
2 and 3 for capacity of high-pressure air orifices. At lower delivery
pressures, the ratio of high-pressure air will be less than indicated
above.
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.
Air-Ductor Assemblies include Hijector, valve, gauge (0 ...
