Labconco 3940200 User Manual page 14

The HEPA-filtered exhaust air can be recirculated into the
laboratory or exhausted outside with the addition of the exhaust
connection kit and remote blower listed in Chapter 7.
The XPert Filtered Balance Station does not include the motorized
impeller and must be exhausted to the outside by a remote blower.
The XPert Filtered Balance Station remote blower may be
switched from the blower switch on the enclosure. See electrical
Requirements in Chapter 2, and Electrical Supply Connections in
Chapter 3. Only one 6" exhaust connection is required for the 2',
3', or 4' XPert Filtered Balance Stations to exhaust to the outside.
Data for the exhaust volume, noise pressure and enclosure static
pressure loss are listed for each filtered enclosure model at face
velocities of 60, 75, 80, 90, 100, and 105 fpm.
