Exhaust and Blower Requirements
The exhaust connection has been designed to accept a 2" x 10" (5.1cm x
25.4cm) nominal exhaust collar. The enclosure has two possible exhaust
connections with either the top exhaust open and the bottom exhaust closed
or vise versa. The bottom exhaust connection is primarily used in
installations where the hose or ductwork needs to be concealed. Labconco
offers accessory transition adapters for the top or bottom exhaust connection
to either a 5" hose or 6" duct. See Chapter 7 for ordering any of these
accessories. For house exhaust, only one exhaust connection is required for
the 2' through 6' enclosures and two exhaust connections are required on the
8' enclosure. Data for the exhaust volume and enclosure static pressure loss
are listed for each enclosure model at face velocities of 60, 80 and 100 fpm.
When using the accessory FilterMate Portable Exhausters, it requires the 5"
Transition Adapter 3912400, which is sold with the FilterMate. Multiple
FilterMate Portable Exhausters require the airflow to be properly balanced.
The 5', 6' and 8' enclosures require two or three FilterMate Portable
Exhausters dependent on face velocity and size.
