Air Liquid Centrifugal Separators
Dirt, water and oils within compressed air systems are a source of
corrosion and contamination. Air contains water vapor which condensates
into liquid droplets due to temperature and pressure changes in your
compressed air system. Trace amounts of oil, pipe scale
and other particulates from the local environment, air compressor,
receiver tanks and distribution plumbing contribute to coating the pipeline and equipment
in the system, coalescing to low points in your plumbing. The coalesced
fluid can be removed with float drain traps without any lose of
compressed air, however centrifugal separators are required for removing
the entrained droplets and slugs of water that accumulate in low areas
of piping where there are no drain traps installed.
separators will remove entrained droplets of water and oil greater
than 10 microns in size with 99% efficiency. They have no internal
filters or components to clean or maintain and are simply a fully welded
pressure vessel with stainless steel internal baffle used to create a
powerful air vortex (centrifugal force) and torturous path which
droplets larger than 10 microns simply cannot navigate.
internal baffle is oriented at a right angle to the inlet nozzle and
thus the vessel must be sized to minimize pressure drop as well as
maximization of the centrifugal force. The design of the stainless
steel element requires sufficient surface area to coalesce the liquid
load and enable drainage.
The most common style of air liquid
separator is in the shape of a "T", having an inlet and outlet 180°
apart and in-line with each other. The T style has a liquid
removal capacity up to 40% of the weight flow. When the expected
liquid load is heavier and "slugs" of water occur, we can modify the
baffle design and length of the vessel body accordingly. We can
also accommodate non-horizontal flow paths, whether that means vertical
or some combination of horizontal and vertical.
material of construction for compressed air systems is carbon steel or
304L SS, although we can fabricate in 316L SS and a variety of other
alloys as needed.
