Bio Safety Cabinet Manufacturer - Class II A2 & B2

Bio Safety Cabinet

Swastik Engineering’s Bio Safety Cabinets (BSC) deliver dependable operator, product, and environmental protection for microbiology, pharmaceutical preparation, and research workflows. Each unit combines precise airflow control with multi-stage HEPA/ULPA filtration to maintain aseptic conditions and prevent cross-contamination.

Designed for Indian lab environments, our BSCs feature low-noise EC blowers, bright shadow-free LED illumination, easy-service prefilters, and a microprocessor controller that continuously monitors face velocity and filter health. Models are available in Class II Type A2, Class II Type B2, and Class III (glove box) configurations to match your containment and exhaust strategy.

Key Features

EC (electronically commutated) blowers for low noise and energy efficiency.
Dual-stage filtration (pre-filter + primary HEPA H14 or ULPA).
Microprocessor controller with real-time face velocity display & alarms.
Audible/visual alerts for low airflow and filter life status.
LED illumination with diffused, shadow-free lighting.
Tempered glass sash with counterbalance; nominal opening for safe containment.
Seamless, cleanable work surface with radius corners for easy wipe-down.
Service ports, electrical outlets, and pass-throughs for instruments.
Low vibration design—ideal for weighing and sensitive procedures.
Quiet operation for improved comfort during extended work periods.

Models & Working Widths

Choose from Class II Type A2 (70% recirculation / 30% exhaust through HEPA), Class II Type B2 (100% exhaust for work with toxic vapors), and Class III (gas-tight glove box for maximum containment). Standard widths: 3 ft, 4 ft, and 6 ft. Custom sizes available on request.

Airflow & Protection

Operator protection via inward inflow at sash to prevent aerosol escape.
Product protection using ISO-class, HEPA-filtered laminar downflow across the work zone.
Environmental protection using HEPA/ULPA filtration on exhaust; B2 connects to building exhaust.

Options & Accessories

ULPA filters (higher particulate efficiency)
Exhaust hard-duct kits (for B2 models)
Gas/vacuum taps, additional power outlets
UV germicidal lamp with safety interlock
Stainless steel work surface & spill tray
Base stand / under-cabinet storage
Custom sizes, special electricals & documentation pack

Construction & Materials

Rugged body in epoxy powder-coated steel for durability; optional chemically resistant polypropylene for aggressive applications. Clear side glazing admits natural light and improves operator comfort. Interior surfaces are smooth and non-porous for rapid cleaning and disinfection.

Typical Applications

Microbiology & culture handling
Pharmaceutical preparation & aseptic dispensing
Biotech research, PCR setup & sample prep
Diagnostic labs & hospital pharmacies
Handling of low-level hazardous aerosols (per model suitability)

Compliance & Standards

Manufactured and tested to relevant international guidelines for biological safety cabinets. Performance validation includes airflow uniformity, downflow/ inflow measurement, HEPA integrity checks, and alarm verification at setpoints.
