Класс I кабинет биологической безопасности
An open-front ventilated cabinet that draws room air inward and filters the exhaust to protect personnel and the environment, but not the handled product.
- Inward Face Airflow
- HEPA-Filtered Exhaust
- Personnel and Environmental Protection
- Open-Front Access
Введение продукции
A Class I cabinet uses inward airflow through the front opening to keep aerosols and particles moving away from the operator. The contaminated air passes through an exhaust HEPA filter before discharge to the room or building exhaust system. Because unfiltered room air crosses the work surface, the cabinet does not protect the product from ambient contamination. The sash, inflow monitor and exhaust connection are configured for the intended laboratory use and installation.
Основные характеристики
The exhaust HEPA stage retains particulate contamination before air discharge.
A sloped viewing sash improves visibility while limiting the working opening.
A removable work tray exposes the lower catch pan for cleaning.
Airflow and sash alarms warn when the designed access condition is disturbed.
Обеспокоенность клиентов продуктами
The cabinet must protect the operator without being misrepresented as a sterile product-protection device.
Aerosols move toward the operator at an open laboratory bench.Inward face airflow carries them into the filtered cabinet exhaust path.
Users expect the cabinet to keep samples sterile.Clear application guidance states that room air crosses the work surface and product protection is not provided.
A raised sash weakens capture at the opening.A sash-position alarm identifies operation outside the selected access height.
Debris accumulates beneath a fixed work pan.Lift-out work sections expose the stainless lower collection area.
