Local Exhaust Ventilation Hood

LEV III™

LEV III™ Local Exhaust Ventilation Hood

Save energy and lab space by moving process applications out of fume hoods.

Most effective and efficient containment for flash Chromatography, Rotovaps, and more.

Containment of ≤0.050 PPM

PROCESS

LEV III™ Local Exhaust Ventilation Hood designed to provide personnel protection.

CONTAINMENT

The LEV III™ is most effective and efficient at containment for flash Chromatography, Rotovaps, and more reaching containment of ≤0.050 PPM.

EQUIPMENT

The enclosure features include a polypropylene structure, hinged doors, dished black phenolic base, laminated glass walls, polypropylene rear wall, and polypropylene rear plenum. Laminated glass walls and LED lighting maximize lighting across the workspace.

FEATURES & BENEFITS

SAFETY

The LEV III™ Series provides safety from chemical vapors generated during processes such as flash chromatography, evaporation from rotary evaporators, and other process equipment applications.

DESIGN
Using a similar design to powder containment enclosures, the LEV III™ series was developed for vapors to be removed from the application and lab. Vapors are pulled to the rear of the enclosure, then up through plenums to keep laminar flow

across the work surface and remove
vapors effectively.

FIRE SUPRESSION

Flow Sciences worked with fire protection specialists to design a fire trigger that detects and automatically extinguishes fires from inside the enclosure. Fire Safety LEV III™s are designed to accommodate large-scale operations that require the superior safety of containment technology.

PORTABLE DESIGN

This enclosure is lightweight which makes it easily movable as the dynamics of the laboratory space changes.
PHENOLIC BASE

The chemically resistant phenolic base is dished to maintain spills and coated to protect the work surface from harmful chemicals

 

GLASS OR ACRYLIC WALLS
FSI uses clear acrylic walls for increased visibility of the application as well as glass options for other chemical processes.

STANDARD SIZES

The LEV III™ comes standard in 2’, 3’, and 4’ options to best fit your application. Custom options are also available.

STANDARD OPTIONS

EXHAUST PORT

4” connection for house systems or can be connected to an FSI remote fan system

 

CLEAR ACRYLIC OR GLASS WALLS

Clear cast acrylic walls for increased visibility and view of operation

 

GAS SHOCK HINGES

Gas Shocks allow for the sash to easily be held in an up position

 

SIDE ACCESS DOORS

Dual side hinged access doors allow for loading and unloading of samples easily

 

REAR PLENUM

The rear plenum pulls air to the rear of the enclosure to effectively and efficiently remove vapors

FRONT SASH

Hinged front sash for ease of operator interaction with equipment as well as loading and unloading equipment. Options include an open sash or a closeable sash.

 
 

DISHED BASE

Dished phenolic base for catastrophic spills.
Can hold 1.5 Liters in the 3’ unit.

 

AIRFOIL

Front airfoil eliminates turbulence and keeps laminar airflow over the operation for better results

 
 

FS1650 ALARM

FS1650 Face Velocity Alarm protects the operator with alerts when airflow is compromised
