Horizontally flow ISO5 clean bench is designed to protect the samples and materials in the hood from contamination by providing the work area with a laminar flow of air, free of particulate contamination.This laminar flow hoods offer a variety of options and accessories such as support stands, stainless steel worksurface, a power outlet, germicidal UV lamp, second hinged front face shield, IV bar, ionizing bar and static dissipative windows.

Worksurface is optional, the clean bench can be ordered with a bottom open frame so it can be placed on worktable. It can be purchased with worksurface and mobile base stand.

Back Plenum provides air re-circulation reduces the percentage of dirty air passed through the filter, overall filter life is extended.

The standard HEPA final filter is 99.99% efficient at particles 0.3 micron and larger to meet the requirement of ISO 5, class 100 cleanrooms. Optional ULPA filters, 99.999% at particles 0.12 micron, are also available.

Clean Bench FAQs

(1)Q: Are all of Kwang's clean benches FS209E 100-level?

A: Yes. We build all of our benches to meet FS209E 100-level (equivalent to ISO 5) cleanliness standards. We test our benches before they leave the factory to ensure quality and compliance with standards.

(2)Q: What are my choices when it comes to clean benches? How should I know which model to pick?

A: Clean benches are classified by the direction of airflow--either laminar or horizontal. We offer clean benches for single users, as well as workstations that are large enough for two users to work at comfortably. Finally, laminar flow clean benches can be customized to feature work areas on both sides, which allows a single or double bench to accommodate two or four users, respectively.

(3)Q: Should I choose a laminar or horizontal flow clean bench?

A: The answer to this question mostly depends on the nature of work involved and customer preference. Both choices will provide the same clean work environment; however, there are pros and cons to each choice. For example, a horizontal bench does not require a step ladder to change the filter, but a horizontal bench also blows air toward the user. In the case where users are handling pungent or potentially hazardous chemicals, a laminar clean bench would be preferable.

(4)Q: What is the standard pre-work procedure for preparing a clean bench?

A: 15-20 minutes before operating the clean bench, turn on the fan and UV light to sterilize the area. Remember to never use the UV light while sitting at the bench.

(5)Q: What happens if the equipment is damaged during the delivery process? What about after sales service?

A: We package all outgoing shipments in sturdy wooden crates to prevent this sort of problem. However, if there is any damage during the delivery process, we will replace the item. Our products are all backed by a one-year free warranty, and our technical support staff can assist you with any issues you encounter.
