Horizontal Ductless Exhaust Purifier
|
 |
|
Shown with optional light and cleanroom
bench
|
This negative-pressure system is designed to ventilate and
purify hazardous fumes generated under the hood, allowing
safe indoor release of exhaust. It is ideal for such operations
as soldering, screen printing, and chemical mixing.
Select the hood material and filter(s) for your application
below. They require a work surface that provides at least
44" (1118 mm) of depth. All components are delivered as a complete turnkey
system, ready for operation.
|
To Order —
| 1. |
The chart below indicates the system
widths available, for two, three or four filter packs.
Each filter pack includes a primary filter (generally, an
activated charcoal filter), and
a final HEPA filter, if exhaust must meet critical cleanliness
requirements. |
| 2. |
Select the desired voltage for the blower/filter
module. Each polypropylene housing incorporates a
1200 CFM (2038.81 m³/h) impeller blower for each filter pack, ensuring
adequate exhaust flow. |
| 3. |
Select the hood material for your application. |
| 4. |
Order the correct number of filters for your hood size. The activated charcoal filter listed
below is 98% effective at removing a wide range of organic
fumes. Terra also offers other purification filters designed
for specific chemicals, such as sulfur compounds, amines,
mercury compounds and formaldehyde. The Charcoal filter contains built-in pre- and post-filters that trap carbon particles that can escape
the purification filter. |
| 5. |
A fluorescent light is recommended for optimal visibility, especially with a
polypropylene or 304 stainless steel hood. Ionizing
equipment is available to protect the work area against
surface charges that can create electro-static discharge.
The optional AirGard® Air Velocity Monitor ensures adequate airflow to remove exhaust fumes effectively. |
| 6. |
Horizontal laminar flow hoods require a work
surface with 44" (1118 mm) of depth. |
