Introduction
Air Science Vented Enclosures provide effective containment of airborne particulates during manipulation and transfer of potent compounds. Our in-house research suggests that even slight modifications of enclosures can result in containment factors from the microgram down to the nanogram. Our turbulent-free design utilizes environmentally friendly, ductless technology in combination with carbon / HEPA filtration to provide precise, safe containment in all applications. Ductless technology also makes installation of dedicated workstations easy, as no additional HVAC design is required. Air Science offers a host of vented enclosures to meet every analytical need.

Ductless Technology: The ECO friendly choice
Advanced HEPA filtration technology offers a safe, high performance alternative to conventional ducted vented enclosures for a broad range of applications.
-
Environmental Benefits
Air Science ductless vented enclosures isolate and trap potent powders down to the nanogram, preventing detrimental impacts to operators. -
Versatile
Each filtration system is selected for its specific application. The Multiplex Filter broadens the range of applications and our bag out HEPA filtration system completely protects operators from potent powders. -
Easy to Install
The ductless hood is self-contained and does not require venting to the outside. Set-up, operation and filter maintenance are straightforward. -
Energy Efficient
Because filtered air is returned to the room, no demands are required of the facility HVAC capacity for make-up air. -
Safe to Use
Cabinet airflow and face velocity protect users from incidental exposures to particulates.

Vented Enclosure Model VE24T; shown with optional mobile cart; and Fume Extractor Model VE-FES. |
A. Filtration: Available with extended life HEPA filtration systems, in conjunction with Multiplex filtration. Our HEPA filters are fitted with a bag-out system to completely protect operators during filter changes.
B. Hose: Each unit is provided with an 8 ft. PVC heavy-walled flex hose with smooth inner surfaces to minimize pressure drop and friction loss.
C. Air Velometer: An analog air velocity meter in the field of vision of the user provides independent backup to the electronic airflow alarm.
D. Single Hinged Front Sash: Hinged Front Sash-Allows full access to the work area.
E. Turbulent Free Design: Our enclosure designs provide a smooth transition of airflow into the enclosure, with the air pulled across the work surface in a uniform, horizontal pattern, reducing the rolling effect found in conventional vented enclosures.
F. Pass Through Ports: Electrical cords and cables are safely routed into the cabinet through pass through ports; located only on the side panels.
G. Plenum-Slotted Baffle: Produces a horizontal airflow pattern in the work area. Baffle can be lowered for cleaning. A 4" OD exhaust port is provided to connect to ductwork or fume extractor.
H. Clear Side Panels:Clear side panels with waste chute allow for disposal bags to be connected and prevent contamination to the surrounding lab.
I. Stand: Optional mobile cart with locking casters.
OTHER FEATURES:
Flexible Design: Air Science offers flexible solutions for any analytical operation. Our ventless enclosures can be plumbed into an existing HVAC setup or incorporated with our Fume Extractor to minimize upfront workstation construction costs.
Standards Compliant: Performance specifications and construction meet or exceed OSHA, ANSI and relevant international standards to assure operator safety.
Validated Performance: Safebridge Consultants have verified and confirmed performance of Air Science Vented Enclosures in controlling airborne concentrations of particulate powder.

PERFORMANCE
VERIFICATION
Safebridge Consultants executed performance verification and assessed the ability of Air Science Vented Enclosures (VE48S) to contain and control airborne concentrations of particulate powder during bench-scale operations.
Procedure:
Three separate operators performed small-scale powder manipulations, utilizing Naproxin Sodium as a surrogate powder to identify the range of potential exposures and respective containment during handling procedures. Air samples measuring the exposure of each operator were taken, culminating in the development of the Potent Compound Characterization chart outlined here.
Note: Model VE48S was used in performance verification.
