Labconco Protector 3944300 User Manual page 8

Chapter 2: Prerequisites
Location and Air Current Requirements
The Protector Demonstration Hood has been designed to contain hazards
by negating typical cross drafts and movements within the opening. As a
precautionary measure it is recommended that the enclosure be placed in
such an area away from:

High traffic areas where walking might cause an air disturbance.

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 exhaust connection has been designed to accept a 2" x 10" (5.1cm x
25.4cm) nominal exhaust collar. The Protector Demonstration Hood has
two possible exhaust connections with either the top exhaust open and the
bottom exhaust closed or vice versa. The bottom exhaust connection is
primarily used in installations where the hose or ductwork will be
concealed. The bottom exhaust is used on the Mobile Protector
Demonstration Hood to conceal the exhaust and facilitate connection to
the FilterMate Portable Exhauster. Labconco offers accessory Transition
Adapters for the top or bottom exhaust connection to either a 5" hose or 6"
duct. (See Chapter 7 for ordering any of these accessories). Only one
exhaust connection is required. The mobile Protector Demonstration
Hood includes the lower 5" hose exhaust transition, FilterMate Portable
Exhauster, 5" hose, mobile cart and work surface. Data for the exhaust
volume and enclosure static pressure loss are listed for each model 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. The enclosure
must be connected to either a dedicated blower, a house exhaust system
or a dedicated filtered exhauster, such as a Labconco FilterMate Portable
Exhauster.
Labconco offers three accessory remote blowers listed in Chapter 7.
