Narrowing Your Filter Choice

Remember we offer three (3) filter styles for single stage collectors:

35A Series

35A274NANOThe 35A series filters (available in Blend, Spun Bond and Nano) are usually secured to the collector from underneath using the provided universal floating gear latches (FGL-U).  The filter gasket usually mates with a conical orifice pan so an additional gasket is not needed when the rim diameter is over 18″.  With an ETG-55 edge trim gasket, they can be mated to collectors with a rim diameter of less than 16 inches.  The ETG-55 becomes the seal so an orifice pan or donut need not be present.

35A series filters are open/closed with a gasket .
35B274NANO filters are open/open with a gasket and can be stacked using the FGL-6 mounting hardware.  See Edge Trim Gasket ETG-55

C Series 

C1425CThe C Series filters (available in MERV 15, Nano only), have a round mounting flange with pre-drilled holes and gasket which make them ideal for mounting to a flat donut or recessing into a cut out structure much like a kitchen sink being recessed into a counter top.  Consider this when making a homemade portable collector. The donuts were nicely illustrated in the April 2013 issue of Fine Wood Working Magazine. If you want a flanged “Spun Bond” consider using a 9E110SB (Open/Closed) filter.

C1425C filters are open/closed with a gasket.
C1425 filters are open/open with a gasket and can be stacked using FGL-6 mounting hardware (dimensions are shown on the pricing/order page).
These Filters have what we feel to be the optimum balance between efficiency, filter area, pleat spacing and dust release properties.

9L Series

9L300NANO (3)The 9L series (available in Nano and Spun Bond) have a 14.25 inch by 16.0 inch steel mounting flange plus gasket and are sometimes used (with a donut) when extra filter area is desired.  These are 34 inches tall and most commonly found stacked together on cyclones and are usually joined at the non flanged ends using the FGL-6 floating gear latches.

9L300NANO Filters are open/open.
9L110SB (spun bond) filters are open/open.
9L300NANOEXT filters are open/open (Nano on outside).

All Filters are made in the USA!
