High Efficiency Coalescing Separators

Selection Guideline

Proper selection of air and dirt separators is always based upon system flow with pipe size as a minimum. Peak efficiency can only be reached when selecting based upon GPM flow in accordance with any manufacturer’s published data.

Removable Bolted Head Discussion

If you have a system that is inherently dirty, you might need an air/dirt separator with a removable head.  This will facilitate the removal of the internal Spirotube bundle for inspection and cleaning.

One of the main items to determine is if this should be located on the bottom or the top of the unit.  Most applications will require this to be on the bottom.  For more information about this, CLICK HERE
