About this file
This document is a Salient Characteristics List for a B-21 Low Observable Maintenance (LO) Fume Hood required for a HAZMAT Room, detailing specific technical requirements for one fume hood unit with delivery within 180 days ARO.
The fume hood must be 4 feet wide with 48-inch work depth and height, featuring OSHA-approved low flow velocities of 50-60 feet per minute. Key specifications include: 12-inch nominal exhaust duct connection, 115V/50-60Hz/20A or 230V/50-60Hz/10A electrical service, ADA-compliant switches, LED lighting behind laminated safety glass, and duplex electrical receptacles. Safety features include an Opti-Zone Rear Downflow Dual Baffle System, removable baffles for cleaning, and an Eco Energy Conservation Air Foil. The unit must be shipped fully assembled with the capability to break down for doorway transport, and include removable access plates for maintenance of plumbing valves and sash adjustment hardware.

BACKGROUND: LO Hazardous Storage room requires fume hoods for mixing paint kits and proper de-gas of paint.
OBJECTIVES: Attain Fume hoods that are no greater than 4 feet wide and have a work depth and height of 48 inches to provide sufficient workspace.
REQUIREMENTS: Provide the specifications listed below.
DELIVERY: Delivery shall occur within 180 days ARO.
Characteristics of Fume Hood: Supply LO with one Fume Hood.
General Requirements
1. The fume hood shall provide superior containment of toxic, noxious, or other harmful materials when properly installed.
2. The fume hood shall meet OSHA approved "low flow" velocities as low as 50-60 feet per minute.
3. The fume hood shall be designed to minimize turbulence and reduce chemical concentrations through the work area.
Exhaust Requirements
1. The exhaust duct connection shall be designed for a 12" nominal duct (12.75" OD) to allow for minimum static pressure loss while operating at 50 to 100 fpm face velocities.
2. The exhaust volume and fume hood static pressure loss shall be listed for each hood model at two sash heights and for face velocities from 40 to 100 fpm.
Electrical Requirements
1. The fume hood shall be wired for 115 Volt, 50/60 Hz, 20 Amp or 230Volt, 50/60 Hz, 10
Amp electrical service.
2. The fume hood shall have low-mounted, factory-wired light and blower switches that are
ADA compliant.
Size and Configuration
1. The fume hood shall be 4 ft wide.
2. The fume hood shall have a large usable interior work depth and interior height of 48" to provide ample working space.
3. The fume hood shall have a by-pass airflow design that promotes full containment as the sash is moved.
Safety Features
1. The fume hood shall have an Opti-Zone Rear Downflow Dual Baffle System that directs horizontal streams of airflow to the rear slots of the primary baffle in a single pass.

2. The fume hood shall have removable baffles for cleaning.
3. The fume hood shall have an Eco Energy Conservation Air Foil and Flush Foil that allow air to sweep the work surface for maximum containment.
Lighting and Accessories
1. The fume hood shall have energy-efficient LED lighting located behind a laminated safety glass shield mounted to the top of the hood.
2. The fume hood shall have duplex electrical receptacles mounted on the right and left corner posts.
3. The fume hood shall have an Upper Dilution Air Supply that provides bypass air from above the work area.
Installation and Maintenance
1. The fume hood shall be shipped fully assembled and eliminate the need for costly onsite assembly.
2. The fume hood shall be designed to easily break down for transport through doorways if needed.
3. The fume hood shall have removable access cover plates for easy access to plumbing valves and sash adjustment hardware.
