Thermo Scientific

Section 1

Description

The Thermo Scientific 1500 Series A2 offers innovative SmartFlow™ Plus
technology; an automatic airflow compensation system that adjusts motor
speed as filters load, without the use of a manual damper. The
SmartFlow™ Plus system ensures safe working conditions, even between
annual certifications.

The plenum assembly consists of a plenum for the downflow blower and a
plenum for the exhaust air blower. Each blower includes a filter. The
exhaust air is discharged through an opening in the top of the cabinet.

Chamber lighting includes one LED bulb for 4 foot models and two for 6
foot models.

The factory-installed UV light is installed in the ceiling at the front of the
sample chamber. For 6 foot model there are two UV lights installed.
