Chapter 2: Prerequisites

!

Proper blower selection can be determined from these exhaust requirements and the total system static pressure loss. For outside exhaust, the enclosure must be connected to either a dedicated blower or a house exhaust system.

Labconco offers accessory remote blowers listed in Chapter 7. Contact Labconco for blower sizing assistance.

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 filtered enclosures. See Chapter 7 for accessory adjustable damper ordering information.

XPert

Station

Electrical Requirements

Standard duplex electrical receptacles should be nearby for connecting the filtered enclosure, or other equipment, such as a balance for weighing operations. The enclosures include iris pass- throughs to allow electrical cords through the back of the enclosure without leaving a large hole for contaminants to escape.

The remote blower for the XPert Filtered Balance Station may be connected to the blower switch on the enclosure. The blower switch is connected to a relay whose wires are terminated in the junction box behind the front panel. We recommend a maximum amperage of 6 amps for this circuit to the remote blower. Please refer to the wiring diagrams in Appendix C. Connect the blower wires inside the junction box to the remote blower per local electrical codes.

Space Requirements

The dimensions for the different models are shown in Appendix B: Dimensions.
