Support Requirements
At a minimum, the supporting structure usually consists of a base cabinet, or
a base stand and chemically-resistant work surface. When setting up a
chemical station, a mobile stand or cart is allowable. Labconco manufactures
a mobile cart with work surface specifically designed to support the Protector
Demonstration Hood and FilterMate Portable Exhauster. The cart is supplied
with the Mobile Protector Demonstration Hood or can be ordered separately
as an accessory. See Chapter 7 for accessories.
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.
