High-Volume Air Handlers

Terra Universal Inc.

High volume air handlers for Terra Universal's modular cleanrooms

  • Adjustable high-volume fan allows precise regulation of pressure inside a cleanroom or other enclosure
  • Optional filter (HEPA or ULPA) removes sub-micron powders and other particles to protect the external environment
  • Ideal for operations with hazardous materials that require negative pressure inside the controlled environment

Select among three standard sizes to meet application requirements.

These high volume air handlers convert any enclosure into a negative-pressure room that safely contains biological materials, pharmaceutical powders, and other potential environmental hazards.

High Volume Air HandlersTypically, exhaust air from the laminar-flow cleanroom is passed to the air handler by means of take-up ducts located along the room perimeter (see illustration). By adjusting the high-volume fan, you can regulate the amount of air exhausted from and recirculated into the room to control the internal pressure. Recirculated air passes back into the room via a ceiling plenum chamber.

For air pressure monitoring, select the Magnehelic® pressure gauge.

High-Capacity, HEPA-Filtered Air HandlerHigh-Capacity, HEPA-Filtered Air Handler

  • Provides a high-volume flow of HEPA-filtered air (3000 CFM average)
  • Ideal for a wide range of critical environment applications --
    • decontamination of surgical zones, even field surgical tents
    • emergency ventilation of contaminated facilities
    • creation of clean zones within an existing clean room

Terra's High-Capacity Air Handler provides up to 3200 CFM (3000 CFM average) of HEPA-filtered air. In a positive-pressure system, it provides particle-free air to a remote enclosure, creating a clean environment in nearly any space. Used as a ventilator, it removes sub-micron particles, including aerosols and most bacteria, from an exhaust flow to allow safe indoor release. Dimensions: 30"W x 48"D x 31"H (67" with built-in stand). Stainless steel housing.
