Flow Max Final Filter for Tornado FAQ

What trucks does the Flow Max Final Filter for Tornado fit?

Tornado style equipment. Check your tube or flange connection against the listing before ordering.

How do I confirm the right final filter?

Match the part number on your old filter, or measure outside diameter, inside diameter and overall length and match all three.

Why does the final filter matter?

It is the last protection before the blower. A loaded filter cuts suction; a torn one lets fine material reach the blower.
