A hybrid system is a single stage dust collector (or its blower) with a pre-separator in front of it. The pre-separator can be a drop-out box, trash can, a Phil Thien baffle, or a cyclone.
To mount the filter, the body (tub) of the collector is usually used, but using a wall or cart-mounted bracket is equally popular.
Available space (height) may influence your filter choice.
Each of the following examples includes a Cyclone pre-separator, Blower assembly, and MERV 15 final stage filter:
Filter on Top of collector body (tub) of a single stage collector. All 35-series filters are compatible with this set up. Note: The illustrated donut may or may not be needed.
