Exhaust and Blower Requirements for Bulk Powder
Enclosures
The exhaust connection has been designed to accept a 2" x 10" (5.1cm x 25.4cm)
nominal exhaust collar. Labconco offers accessory transition adapters for the top
exhaust connection to either a 5" dia. hose or 6" dia. duct. 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. See the following chart and refer to Chapter 3 for installation startup. See
Chapter 7 for ordering any of these accessories, FilterMate Portable Exhausters or
remote blowers.
Only one exhaust connection is required for the 5' and 6' enclosures when
connecting to house exhaust. Two exhaust connections are required for the 8'
enclosure when connecting to house exhaust. A 3981600 Exhaust Transition (6" x
6" x 8") may be used for the 8' enclosure connected to house exhaust. Data for the
exhaust volume and enclosure static pressure loss is listed for each enclosure
model at face velocities of 60, 80 and 100 fpm.

Proper blower selection can be determined from these exhaust requirements and
the total system static pressure loss. The enclosure must be connected to either a
dedicated blower, a house exhaust system or dedicated filtered exhausters, such as
FilterMate Portable Exhausters. Labconco offers accessory remote blowers and
FilterMate Portable Exhausters listed in Chapter 7.
