Zero Casing Leakage Laboratory Exhaust Air

Terminal

Figure 1. External Shaft Seal of Model LGZ Exhaust

Terminal.

The Siemens Zero-Casing Leakage Laboratory

Exhaust Air Terminal is an industrial grade, easy-to-

install, pre-packaged airflow measurement and

control terminal unit designed for the requirements of

ductwork in biocontainment facilities. When used with

the Laboratory Controller, it provides stable and

precise exhaust airflow control over the entire range

of airflow requirements.

Features

• All units leak less than 0.1% per minute of internal

volume per ASME N510 Pressure Decay test.

• Individually factory leak tested to 15” W.C. (3750

Pa).

• External shaft seals ensure zero casing leakage.

• Solid stainless steel damper shaft on Teflon®.

bushings for smooth, maintenance free operation.

• 20 Gauge 316L stainless steel construction with

flanges meeting SMACNA industrial standard.

• Orifice plate airflow measurement resists fouling.

• Flow signal tubing sealed with 2-valve manifold

Optional 5-valve manifold with HEPA filters.

• Low non-recoverable static pressure loss

• Sizes 4, 6, 7, 8, 9, 10, 12, 14, 16 & 18 inch

diameter. Airflow capacities from 35 to 5655 cfm.

• Factory-mounted measurement and control

devices to simplify installation (optional).
