Laminar Flow Hoods

Laminar Flow Hoods (Clean Benches)

Terra Universal manufactures vertical and horizontal laminar flow hoods and workstations (laminar flow clean benches) for any space and cleanliness requirement. The freestanding models below provide ample workspace for large process equipment. Compare free-standing models in the chart below. Portable benchtop laminar flow hoods are also available. Most are available with HEPA or ULPA air filtration modules. Terra also customizes laminar airflow cabinets to meet unique requirements — call to discuss your application.

Vertical Laminar Flow Workstations

 

Vertical Laminar Flow Workstations

These workstations incorporate low-noise, low-vibration 99.99% efficient HEPA or 99.999% efficient ULPA fan/filter modules that remove particulate airborne contamination from the vertical laminar air flow. Several sash options are available, along with static-neutralizing ionizing equipment and a complete range of work surfaces.

Horizontal Laminar Flow Stations

 

ValuLine Vertical Laminar Flow Workstations

ValuLine workstations provide a low-cost solution for laminar flow applications. Available in many widths, these hoods feature a counterweighted sliding sash. The modular design accommodates many work surfaces. Select HEPA or ULPA filtration modules.

Horizontal Laminar Flow Stations

 

Horizontal Laminar Flow Stations

You choice of 99.99% efficient HEPA or 99.999% efficient ULPA filters help meet the most stringent contamination requirements in the pharmaceuticals, biotech, electronics and semiconductor industries. These horizontal laminar flow cabinets incorporate a stainless steel work surface and are available with ionizing modules

Portable CleanBooth

 

Portable CleanBooth

Mobility and versatility make this versatile clean bench ideal for operations with freestanding process equipment, as well as bench-top kitting or assembly. Side curtain packages optimize the laminar air flow beneath the fan/filter modules.

Narrow Profile Laminar-Flow Hood

 

Narrow Profile Laminar-Flow Hood

Terra’s economical, space-saving Narrow Profile Laminar Airflow Hood uses dual filter fan units to provide a consistent laminar flow of clean air to the work surface.
