Chapter 2: Prerequisites

Support, Vibration and Movement

Requirements

At a minimum, the supporting structure usually consists of a base cabinet and chemically-resistant work surface.

•A stand or mobile bench is not recommended if the enclosure will be used for precise weighing of powders.

Location and Air Current

Requirements

The Purifier Filtered Enclosures have been designed to contain hazards by negating typical cross drafts and turbulence within the opening. However, as a precautionary safety measure and a higher level of quality management, it is recommended that the enclosure 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.

Exhaust and Blower

Requirements

The Purifier Class I Enclosure and Purifier Filtered Enclosure use an integral motorized impeller to draw room air past the operator and through the enclosure. This contaminated air is then pushed through the HEPA filter. The HEPA-filtered exhaust air is then forced out the top of the enclosure. An optional carbon filter may be installed on the downstream side of the HEPA filter to protect against nuisance odors.

The HEPA-filtered exhaust air can be recirculated into the laboratory or exhausted outside with the addition of the exhaust connection kit and remote blower listed in Chapter 7. Data for the exhaust volume and enclosure static pressure loss are listed for each filtered enclosure model at face velocities of 60, 75, 80, 90, 100, and 105 fpm.
