Vertical Ductless Exhaust Purifier
Hoods — Vertical Ductless Exhaust Purifier
Shown with optional light,
AirGard® and cleanroom bench

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" (813 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 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.
6. Horizontal laminar flow hoods require a work surface with 32" (813 mm) of depth.
