Proper blower selection can be determined from these exhaust requirements
and the total system static pressure loss. The enclosure must be connected to
a dedicated blower, a house exhaust system or a dedicated filtered exhauster,
such as a Labconco FilterMate. When using multiple FilterMates, the airflow
must be balanced.

Labconco offers accessory remote blowers listed next and in Chapter 7.

If the enclosure is connected directly to a house exhaust system, an adjustable
damper (or valve) must be installed to control the airflow properly. This is
equally important when a house exhaust system is controlling multiple
balance enclosures or ventilation stations. See Chapter 7 for ordering an
accessory adjustable damper.
