Support, Vibration and Movement
Requirements
At a minimum, the supporting structure usually consists of a base cabinet or base
stand and chemical-resistant work surface. See Chapter 3 for setting up installation.
Location and Air Current Requirements
The Protector Work Stations have been designed to contain hazards by negating
typical cross drafts and turbulence within the opening. Normal air movement does
not affect installation of the Protector Work Station. However, as a precautionary
safety measure and a higher level of quality management, it is recommended that
the Protector Work Station be placed in an area to avoid:
High traffic areas where walking might cause an air disturbance or be a
nuisance.
Overhead or wall HVAC diffusers, fans, radiators or other lab equipment
producing air currents.
Next to doorways or windows that may be opened.
Do not position the unit so that it is difficult to operate the main
disconnect device.
Ne placez pas l'appareil de sorte qu'il est difficile de faire

Exhaust and Blower Requirements
The Protector Work Station draws room air past the operator and through the
enclosure. This contaminated air is either pulled through a carbon filter and
exhausted to the room or exhausted outside by a remote blower.
Data for the exhaust volume and enclosure static pressure loss are listed for the
Protector Work Station at face velocities of 60, 80 and 100 fpm.

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.
