Laboratory Room Exhaust Air Terminal
Figure 1. Laboratory Room Exhaust Air Terminal.
The Laboratory Room Exhaust Air Terminal is an
industrial grade, easy-to-install, pre-packaged
airflow measurement and control terminal unit.
When used with the Laboratory Room Controller, it
provides fast-acting, stable and precise laboratory
general exhaust airflow control over the entire range
of room airflow requirements.
Measurement of airflow is accomplished by unique
orifice plate or four quadrant sensing technology
that minimizes pressure loss and duct obstruction,
while maintaining measurement accuracy at 2% of
actual flow (sensor only). Airflow control uses a
round single blade damper. The terminal is
comprised of 22 gauge-galvanized steel including
the damper and orifice plate components. For
corrosive environments, 316L stainless steel or
Teflon® is available as an option. Slip or flange end
fitting connections may be selected to match the
ductwork construction. Flanges comply with the
SMACNA Round Industrial Duct Construction
Standard (RIDCS).
Features
Orifice plate airflow measurement or four
quadrant airflow sensors with multipoint, center
averaging and signal amplification.
Solid stainless steel damper shaft on Teflon
bushings for fast acting control and maintenance
free operation.
Option of three different materials for
construction,
- Galvanized steel for non-corrosive, general
applications.
- 316L stainless steel for potentially corrosive
applications.
- Teflon for highly corrosive applications.
Low non-recoverable static pressure loss.
Eleven standard sizes with airflow capacities from
36 to 5591 cfm additional sizes are available.
Only two pivoting mechanical points, the damper
shaft ends in Teflon bushings are exposed to the
airstreams.
Field commissionable and adjustablenot
dependent upon factory calibration.
(Optional) Factory-mounted measurement and
control devices to simplify installation.
Electronic or pneumatic damper control.
Meets equipment requirements of ASHRAE 62.1
Sec. 5.
LGE can be mounted in any orientation.
Blade seals included as standard.
Clean, sealed shipping bags available for LEED
IEQ projects.
Lab DXR (IP & MSTP) control packages available
