3. Paramount® Ductless Enclosures
Carbon Filtration: The use of carbon media derived from
granulated coal carbon or coconut shell carbon to chemically
adsorb vaporous/gaseous contaminants
Why Carbon?
Why coconut shell carbon media?
Adsorption

4. Paramount® Ductless Enclosures
Properties that affect filtration efficiency
♦ Chemical’s molecular weight
♦ # Carbons in molecular structure
♦ Vapor pressure
♦ Chemical displacement
♦ Temperature
♦ Humidity

5. Paramount® Ductless Enclosures
Activated Carbon vs. Treated Carbon Filters
Activated Carbon Treated Carbon
Organic Filters Acid/Sulfur
• # Carbons Formaldehyde/Formalin
• Molecular weight Ammonia/Amine
• Adsorption only Radioisotope
Incomplete saturation Mixed Bed
Stripping from media • Treated with chemical
100% activated carbon • Neutralization
• Complete saturation
• 75% treated/25% activated

6. Paramount® Ductless Enclosures
Self‐contained work stations that use
carbon filters to protect operator from
harmful vapors
Require no ductwork and can be moved
from lab to lab
Utilize energy‐efficient motors (ECM)
Patented containment features
Stackable filters for multiple chemical
applications
Digital control center with vapor sensor
and airflow monitor

7. Paramount® Ductless Enclosures
Energy efficient ECM motor uses less
energy, runs cooler and quieter.
Patented containment enhancing
design features ensure operator
protection from fumes, vapors, gases
and particles.
LCD display with digital control center,
Safety‐First™ Vapor Sensor and Smart‐
Flow™ Airflow Monitor to monitor
filter breakthrough and air speed to
maintain user safety at all times.

9. Paramount® Ductless Enclosures
Seven different stackable filters
can be combined to handle
different chemicals at the same
time.
Solid and durable construction.
Available in multiple widths,
depths and heights.

Energy Savings
Recirculation of filtered, tempered air eliminates energy waste
associated with traditional, ducted fume hoods.
The ECM motor and light fixture in a 3′ Paramount unit use only 65
watts — about as much energy as one 60 watt light bulb!
(Previous 3’ model used 330 watts)
Reduced Heat Load
3’ unit heat load of 222 BTU/hr
Previous 3’ model heat load of 1126 BTU/hr
Noise Reduction
3’ ranges 46‐62dbA vs. previous model 65dbA
6’ ranges 57‐66dbA vs. previous model 68dbA

Containment enhancing features
Patented slotted rear baffle promotes
horizontal laminar flow reducing
turbulence
Upper Containment Sash Foil directs
contaminants away from the
operator’s breathing zone

12. Paramount® Ductless Enclosures
Containment enhancing features
Side Entry Air Foils promote horizontal
flow and direct airflow into the
enclosure work area
Aerodynamic airfoil with Clean‐Sweep™
openings directs air into the enclosure
and across the work surface

Safety-First™ Vapor Sensor
Detects chemical breakthrough and filter saturation
Visible/Audible alarms are displayed on LCD display
Vapor sensor optimal detection concentration 1‐10ppm vs.
current sensor calibrated at 50ppm.
Two sensors allow safety backup monitoring of breakthrough.
Accurate detection of breakthrough maintains operator safety.
Early alert detects initial breakthrough and provides warning
message to user that approximately 5‐10% filter life remains.
