*   Filters for Cyclones   *

These Woodworking Cartridge Filters are ideal when used as after filters for the high efficiency cyclones designed by Bill Pentz.  Be sure to see Bill's website for design details, and check out the Clear Vue Cyclones by Bushey Enterprises.  The hot set up for a cyclone system is a pair of the 9L300BL filters, in conjunction with an inlet plenum and dropout box.  These are now available directly from Clear Vue.  Click on the image on the left for a larger, printable view.  When applying the 9L300BL to a cyclone, one important factor to look at is air flow.  As a general rule, we recommend a pair of filters for any system moving more than 700 or 800 CFM.  (800 cfm corresponds to the required flow in a properly designed 6" dust collection system.)  If your system is designed to move less than 700 CFM, then a single filter will do just fine.  Remember, a single filter has 4 times the pressure drop of a pair of filters, since the math includes a square function, so there are huge benefits to having that extra filter area.  If you have specific questions, or need a recommendation, please give us a call.  We are now offering out Farr Style cartridges in the Advanced NANOFIBER laminated which carries the MERV 15 efficiency rating.   Our new 9L300NANO has been tested and approved by Bill Pentz for use on fine woodworking dust.  Bill’s website can be accessed HERE where you will find a vast amount of information for the woodworker.  Please go tour Advanced NANOFIBER page for more information on these filters

*     Cartridge Filters for BAG type collectors    *

CHOOSING A FILTER

If the tub diameter is over 18 inches and the internal conical orifice plate is smooth like the HF shown ( left ) below, a 35A series filter will probably be your best bet.

If the tub diameter is less than 18 inches or if the conical orifice plate is ramped ( shaped like an auger ) the “ C “ series filter should be considered. For these collectors you must make a donut for the filter to seat against.

If your collector is different from the above or if you will be incorporating an internal Phil Thien Baffle, please give us a call.
