bioMARK-II-B2 – Class II Type B2 Biohazard Safety Cabinet (Total Exhaust Cabinet)

The bioMARK-II-B2 is a Class II Type B2 Biohazard Safety Cabinet, also known as a Total Exhaust Cabinet, designed to provide maximum personnel, product, and environmental protection. Unlike other biosafety cabinets, the B2 model features a 100% exhaust system with no air recirculation, ensuring the highest level of containment for hazardous biological agents and chemical vapors. It creates a Class 100 ultra-clean work zone with vertical laminar airflow, making it ideal for applications requiring absolute contamination control.

Key Features & Benefits

• ✔ NSF Standard 49 Compliant Filtration System – Ensures superior air purification and compliance with global safety standards.
• ✔ Total Exhaust System (100% HEPA Filtered) – No recirculation, eliminating contamination risks.
• ✔ Maximum Containment – All contaminated plenums are surrounded by negative pressure, virtually eliminating leakage.
• ✔ Balanced, Low-Noise Blowers – Engineered for continuous operation with optimized motor capacity.
• ✔ Durable & Hygienic SS304 Construction – Seamless work zone with minimal welded joints prevents contaminant buildup and rusting.
• ✔ Adjustable Front Sash Opening (8") – Includes alarm system to prevent over-opening and maintain containment.
• ✔ UV Germicidal Lamp (15W or 30W) – Provides effective preliminary sterilization.
• ✔ Ergonomic Illumination – Electronically ballasted fluorescent lighting enhances operator comfort and visibility.
• ✔ Aesthetic & Robust Design – Powder-coated GI body in dual-color finish (fully SS304 construction available upon request).
• ✔ Exhaust HEPA Module – Positioned above the false ceiling or outdoors, allowing easy access for maintenance.
• ✔ Comprehensive Testing & Calibration – Factory and on-site testing for HEPA filter integrity, cleanliness, and airflow validation. All instruments are calibrated with NABL or International Standards traceability.

Optional Features

• ✔ Virus Burnout Unit – Additional sterilization for maximum safety.
• ✔ Second Stage Exhaust HEPA Filtration – Provides enhanced air purification to meet advanced safety requirements.

Critical Considerations for Installation

• ✔ Compensating Fresh Air Supply – Since the biosafety cabinet exhausts conditioned air, a Positive Pressure / Fresh Air Module is recommended to maintain a stable lab environment.
• ✔ Air Conditioning Requirements – For every 200 CFM of fresh air added, 1 ton of AC should be installed. A 3' Type B2 cabinet requires a minimum of 2 TR AC.
• ✔ Heat Compensation for Exhaust Air – Exhaust air at 450 CFM would require 15 kW of heating to maintain 80°C, which is energy-intensive. To avoid this, an additional HEPA filtration system with a blower is recommended, following USA & European standards.
• ✔ HEPA Filter Integrity Testing – All HEPA filters must be tested using an Aerosol Photometer post-installation to ensure environmental and operational safety.

Warranty & Additional Services

• ✔ 12-Month Warranty (excluding consumable parts and accessories)
• ✔ IQ/OQ Documentation Available Upon Request
