Regulating Air flow
There are different ways we can treat compressed air and different tools that are used in these processes. Learn more about the process of regulating compressed air flow here.
In a lot of cases, applications require constant pressure in the compressed air system. This, in turn, requires that the compressed air flow from the compressor center is regulated. In this article we will talk about flow regulation in dynamic compressors.
Inlet regulation
Outlet regulation
Load-unload-stop
Previously mentioned regulation methods can be combined to control the compressor unit. Two modes are commonly used:
Modulating: The excess flow is released into the atmosphere (or the inlet), but energy consumption is unchanged.
Auto dual: The flow turndown of the unit will be limited to the turndown of the intake valve and/or the outlet guide vanes for flows below the turndown limit. The regulation system fully closes the inlet valve at the same time as the compressor's outlet is opened to the atmosphere (compare with the displacement compressor).
The off-loading power is still relatively high, representing 20% of the full load power, depending on the design of the impeller etc.
Speed regulation
Speed regulation has a similar effect as the use of inlet guide vanes. Flow can be varied with constant pressure within the compressor turndown range. At higher powers, speed variation is less advantageous, due to the high cost of the required drive installation.

Installing a compressor system is easier than it used to be. There are still a few things to keep in mind though, most importantly where to place the compressor and how to organise the room around the compressor. Learn more here.
