Porous Gas Injectors
Inyo Process’ line of porous metal seamless injectors create bubbles smaller and more numerous than a drilled pipe or other types of spargers. With greater gas/liquid contact area, the time and volume required to dissolve gas into liquid is reduced.
The most important factor when injecting gas into liquid is to increase the surface area of the gas to ensure fast absorption into the liquid. This is accomplished by reducing the bubble size, which creates many slow moving, tiny bubbles that result in a large increase in absorption.
The advantage of the Inyo Process injectors is the tight and consistent pore structure to all of our stainless steel gas injectors. This consistent pore structure provides a high bubble point which results in tiny, consistent bubbles.
All stainless construction lasts for years. The durable all –welded construction will remain trouble free for many years. Often the porous injectors can be easily cleaned using a ultrasonic bath.
Shown above is a 2" diameter x 24" long porous injector. Inyo can provide a variety of sizes ranging from 1/2" diameter to 6" diameter with all types of end fittings and configurations
Inyo Process can provide a variety of styles. If you need a nonstandard size or special fitting, or specialty metals such as Monel or Hastelloy C-276, we are able to provide solutions.

Porous Metal Injector & Sparger Sizing
This paper describes the sizing of a porous stainless steel sparger or injector.
Installing a porous injector in a pipe will always result in greatly reduced bubble size. The gas will exit from the outside of the porous injector, and the bubbles are immediately sheared by the liquid, resulting in very tiny bubbles and greater absorption.
Injectors can be mounted across the pipe diameter

Porous Stainless Steel Injectors are also available as removable corporation stop style.These type of injectors can be removed while the system is under pressure.Call factory for more details
We can also supply a complete line of external spargers, which use high-shear tangential forces to produce a stream of micro-bubbles.
