For thimble-ducted glove boxes, the proper remote blower selection can be
determined from these exhaust requirements as the remote blower only needs
to be sized for the static pressure loss of the ductwork system. The thimble
ducted exhaust blower should be sized for 25% additional airflow. When
exhausting a glove box to the outside, it should be connected to a dedicated
remote blower.
Labconco offers accessory remote blowers listed in Chapter 7. Contact
Labconco for blower sizing assistance.
When a glove box is connected to a remote blower exhaust system, an
adjustable damper (or valve) should be installed in the duct to control the
airflow volumes properly. See Chapter 7 for Exhaust Dampers.
Electrical Requirements
Electrical services should be nearby for connecting the glove box, and
accessory equipment. The glove box is rated 115V, 8A or 230V, 4A or
100V, 8A. A convenience duplex outlet is located inside the glove box and is
rated for 115V, 5A or 230V, 2A or 100V, 5A. A four outlet power strip is
included with the 115V XPert Weigh Box for connection to the duplex outlet.
International outlet strips are listed in Chapter 7.
Space Requirements
The dimensions are shown in Appendix B: Dimensions. Provide adequate
space to the right of the transfer chamber for loading and unloading.
