Overview
Process Protection Systems are designed to maintain controlled conditions required to protect sensitive operations from particulate and biological contamination. These systems integrate airflow control, high-efficiency filtration, and physical containment to ensure process integrity across laboratory and production environments.
Depending on the application, protection is achieved through controlled airflow patterns, negative pressure containment, and HEPA or ULPA filtration. Air handling systems regulate the movement of clean and contaminated air, either recirculating it through filtration stages or exhausting it externally to prevent cross-contamination.
Biological Safety Cabinets (BSCs) are a core component within process protection applications, providing localized containment for handling biological agents, hazardous compounds, and sensitive materials. Different cabinet classes are available to match required biosafety levels, airflow configurations, and exhaust strategies.
LAMINAR FLOW HOODS - CONTROLLED AIRFLOW WORKSTATIONS FOR PARTICLE-SENSITIVE PROCESSES
Precision-engineered enclosures designed to deliver consistent laminar airflow and high-efficiency filtration for contamination-controlled environments across pharmaceutical, biotech, and semiconductor applications.
Overview
Laminar Flow Hoods are localized clean air systems designed to provide a controlled environment for processes requiring low particulate contamination. These units generate a unidirectional airflow that continuously removes airborne particles from the work area.
The system operates using integrated fan filter units (FFUs) that draw ambient air, pass it through high-efficiency filtration (HEPA as standard, optional ULPA), and deliver a uniform laminar airflow across the workspace. Airflow can be configured in either vertical or horizontal orientation depending on application requirements.
This continuous flow of filtered air maintains a clean working zone by displacing contaminated air and minimizing particle accumulation during critical operations.

BIOLOGICAL SAFETY CABINETS (BSC)
Enclosed, ventilated workspaces designed for personnel, product, and environmental protection when handling biological agents and hazardous materials.
Overview
Biological Safety Cabinets (BSCs) are enclosed laboratory systems engineered to provide controlled airflow and high-efficiency filtration for safe handling of biological materials. These systems are designed to protect personnel, the surrounding environment, and, depending on the cabinet class, the product itself.
Airflow is managed through a combination of inward face velocity and HEPA/ULPA filtration. Contaminated air is either recirculated through internal filtration systems or exhausted externally, depending on the cabinet classification. Negative pressure zones within the cabinet prevent leakage of hazardous particles into the laboratory environment.
BSCs are used in laboratories working with microorganisms, radionuclides, and chemical agents under defined biosafety levels. Different cabinet classes provide varying levels of containment and airflow configurations to match specific application requirements.
