  • Modular activated charcoal filter/blower units and hoods of varying sizes and materials form versatile controlled-environment enclosures
  • Innovative, economical design lets you configure a system for any of three basic applications:
    • Horizontal or Vertical Ductless Fume Hood purifies wide range of noxious fumes for safe indoor release
    • Exhaust Fume Hood directs fumes to an in-house exhaust system
  • Filter/blower module also functions as a stand-alone air purifier (mounted to wall or ceiling) or as a clean-air feed system (for a remote enclosure)
  • Powerful 1200 CFM blowers with unique plenum chamber ensure uniform air velocity throughout the entire work area
  • Modular design minimizes turbulence and noise associated with large, centralized filter/blower systems
  • Custom modifications provide economical solutions to unique requirements
  • 304 Stainless steel hood frame supports your choice of five different panel materials

Terra's Environmental Control Modules allow you to construct an exhaust purification/removal system for virtually any sized enclosure. Hoods are available for use with two, three, or four filter/blower modules, and several hoods of any size can be positioned together to form as large a work station as you need.

The low-profile filter/blower module incorporates 1200 CFM impeller blowers designed for quiet, continuous duty.They draw exhaust fumes through a charcoal purification filter and then release them through 8"-diameter exhaust flanges.

Modular Hoods to Fit Any Requirement Hoods are designed to fit on a standard table when interfaced with the filter/blower module. Hoods for vertical flow applications are designed for tables 30" deep or deeper. Hoods for horizontal flow applications require a 34"- 44" deep table to accommodate both the hood and filter/blower. Both hood designs are available in three widths. All hoods feature a segmented access shield that allows ample operator access to the working area and also closes completely to minimize contaminants. Stainless steel hood frames support your choice of five different hood materials.

Hoods are available in five materials. Terra's light-weight, transparent static-dissipative PVC, which features a surface resistivity between 106 and 108 ohms/square, safely eliminates static build-ups and the particles they attract, making surfaces clean inside and out. Nondissipative PVC and polypropylene enclosures are ideal for use with a wide range of caustic fumes.

All hoods feature a stainless steel reinforcement frame for optimal strength and stability. Hoods can also be equipped with a conduit flange to allow remote applications. Simply specify desired location of input/exhaust when ordering.
System Options

Fluorescent Lighting is recommended for use with stainless steel and polypropylene hoods. An externally mounted fixture is designed not to interfere with conditions under the hood. UV tubes are ideal for promoting sterile conditions in microelectronics and biological processes.

Cleanroom Table features a sealed laminate nonconductive surface to minimize particle accumulation and ensure easy cleaning. Standard table features an epoxy-finished steel frame with stainless steel sleeves on the lower support member to prevent scuffing.

AirGard™ Air Velocity Monitor
Monitors air velocity (70 - 250 ft/sec; 0.35 - 1.25 m/sec) to ensure ventilation efficiency. LCD display shows constant digital reading of face velocity; and LED and audible High/Low alarms indicate when air speed falls below user selectable level. Part number includes flush-mount installation on specified Terra Universal hood (laminar flow or exhaust fume).

Power Strips include 4 grounded electrical receptacles, a master on/off switch, and a 15-amp circuit breaker. Standard mounting is on the interior right side of the hood.
