Vertical Ductless Exhaust Purifier
This negative-pressure system draws exhaust fumes upwards
from the work area through an exhaust purification filter
to allow safe indoor release. 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
32" of depth. All components are delivered as a complete turnkey
system, ready for operation.
To Order
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 pre- and post-filter, and a final
HEPA filter, if exhaust must meet critical cleanliness
requirements.
Select the desired voltage
for the blower/filter
module. Each polypropylene housing incorporates
a 1200 CFM impeller blower for each filter pack, ensuring
adequate exhaust flow.
Select the hood
material for your application.
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.
Pre- and post-filters trap carbon particles that can escape
the purification filter.
A
fluorescent light is recommended for optimal visibility,
especially with a polypropylene or 305 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 Meter ensures adequate air flow to
remove exhaust fumes effectively.
Horizontal laminar
flow hoods require a work
surface with 32" of depth.

AirGard Air
Velocity Monitor
Monitors air velocity (70 - 250 ft/sec; 0.35 - 1.25 m/sec)
to ensure laminar flow or ventilation efficiency. Refer

Purification Filter
(Activated charcoal)
This filter is now bonded and encapsulated in a sleeve
that functions as a prefilter negating the need for a
separate prefilter
