Air Liquid Centrifugal SeparatorsT style centrifugal separator

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.

Centrifugal 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.

The 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.

The standard 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.
