General Information
The Vented Balance Enclosures have been designed and engineered to provide operator safety
from airborne particulates during small scale laboratory weighing. The unit features a 25.4mm
thick chemical resistant phenolic resin base, top-mounted HEPA filter fan assembly, horizontal
and vertical airfoils, removable rear baffle, cable-pass thru ports, airflow alarm, and optional Bag
Port chute for waste. The HEPA filter fan assembly includes a backward curved impell
er, panel
HEPA Filter, speed control, on/off switch, and house exhaust connection.
During normal operation, the backward curved impeller maintains a face velocity into the
enclosure which prevent particulates from escaping. The impeller pulls air into the enclosure,
through the back baffle and then through the HEPA filter. Any particulates that are generated
inside the enclosure are swept away from the operator and into the back baffle. The air flow alarm
continually monitors the face velocity and alarms when air flow deviates -20% from target face
velocity.
