Clean benches and laminar flow hoods utilize state-of-the-art technology to ensure a clean, particle-free work environment for non-hazardous materials. The HEPA filtered air that is generated by clean room benches ensures that the work surface is 99% free of particles at 0.3 microns.
Clean Air Products’ laminar flow benches and laminar flow hoods provide high purity micro-environments inside or outside a cleanroom. We offer a range of both horizontal and vertical laminar flow benches, in standard and custom styles, to meet your cleanroom needs.

Vertical vs Horizontal Laminar Flow Hoods The difference between horizontal and vertical flow hoods can be seen in the design of each system. Horizontal units are appropriate when the work environment requires a surface that must be in first contact with the clean air stream that is provided. Conversely, vertical flow benches are appropriate with exhaust systems and should be used whenever irritants or noxious chemicals will be used in a work area. Whether it is a horizontal or vertical flow bench, proper enclosure design helps prevent backwash and ensures that the laminar air flow continues to protect work on the surface of the clean bench.
Laminar Flow Bench HEPA Filter
A common component in any clean bench is the HEPA filter. The HEPA filter (High Efficiency Particulate Air) removes particulates, generally called aerosols, such as micro-organisms, from the air. Additionally, the HEPA filter does not remove vapors or gases. Other HEPA filter features include:
HEPA filters are manufactured from borosilicate glass microfibers
Flat filter sheets are pleated to increase the overall surface area
Pleats are separated by aluminum baffles which direct the airflow through the filter
Our standard cleanroom benches are an easy and effective way to create a freestanding, ultra-clean mini environment. Class 100 (ISO Class 5) and Class 10 (ISO Class 4) standard cleanroom benches are available to meet your needs. HEPA filtration and powerful horizontal or vertical undirectional air flow “washes” away particulates and prevents contaminants from entering the clean work zone.

Work area height: from 22.25” to 46.25” (565 to 1,175 mm)
Clean Air Products’ custom clean room benches are designed for more specialized applications. These compact cleanroom solutions are designed to fit on shelves, to sit on counters or tabletops, or as freestanding units.
Numerous laminar flow hood options are available, including horizontal laminar flow clean benches, vertical laminar flow wash through base clean benches, vertical laminar flow exhausting clean benches, and recirculating clean benches, and more.
Horizontal Flow Laminar Clean Benches
These custom clean benches are designed to be set on a table top. Some of the unique features of our horizontal flow laminar clean benches, include:
Our vertical flow laminar clean benches are specifically designed to create a freestanding ultra-clean mini-environment. These clean benches are available in numerous sizes and styles, and are precisely engineered to provide outstanding solutions for many air filtration applications. Some of the features of our vertical flow laminar clean benches, include:
Welded steel cabinet with powder coated finish
White vinyl coated steel back panel
Clear polycarbonate end shields
PSC motors with ball bearings
And more
Laminate Flow Hood Applications
For facilities that process clean-critical products in quantities too low to justify the cost of a full cleanroom, a cleanroom bench is the perfect solution. Undirectional air flow benches provide advanced product protection by ensuring that the work in the bench is exposed only to HEPA-filtered air. Applications that commonly utilize laminar flow benches include:
