Ductless Fume Hoods
Introduction
Ductless Fume Hoods (DFH) are a series of high efficiency products designed to
protect the user and the environment from hazardous vapors generated on the work
surface. At the heart of the DFH product line is the innovative
airflow filtration technology that creates a safe work environment
over the widest range of applications in the industry.
Features
• High efficiency ebm-papst EC blower.
• Energy saving LED lighting.
• Protects the operator from fume and (with added
HEPA/ULPA filter) particle hazards.
• Improved filter clamping eliminates bypass leakage.
• Low airflow alarm.
DUCTLESS TECHNOLOGY
THE ECO-FRIENDLY CHOICE
Advanced carbon filtration technology offers a safe, high performance alternative to conventional duc ted fume hoods for a broad
range of applications.
• Environmental Benefits.
Ductless fume hoods isolate and trap chemical vapors to prevent
ecological impact through release into the environment.
• Versatile.
Each filtration system is selected for its specific application. The
airflow filter broadens the range of applications. Carbon filters
are available in many configurations for use with vapors or organic
solvents, acids, mercur y and formaldehyde. HEPA/ULPA filters can
add to biological safet y.
• Easy to Install.
The duc tless fume hood is self-contained and does not require
venting to the outside. Many units are portable and may
be moved from one location to the next with minimal downtime
and without filter changes. 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 capacit y for make-up air.
• Cost Effective.
Facilit y duc twork, HVAC and construction costs are eliminated.
• Safe to Use.
Workstation airflow and face velocity protec t users from incidental
exposures to fumes.
• Self testing.
Electronic airflow monitoring assures continuous safety.
