AIRTECH BLB-1000 Vertical Laminar Flow Clean Bench

Overview

The AIRTECH BLB-1000 Vertical Laminar Flow Clean Bench is an ISO 5–certified (Class 100 per US FED STD 209E) personnel-protective workstation engineered for non-hazardous applications requiring particle-free environments. Unlike biological safety cabinets, the BLB-1000 operates as a unidirectional vertical laminar flow device: ambient air is drawn through a pre-filter, conditioned by a centrifugal blower, and then passed through a certified H14-grade HEPA filter (EN 1822) before being delivered uniformly downward across the work surface at ≥0.3 m/s. This controlled airflow establishes a sterile barrier that prevents airborne particulate contamination of samples, reagents, or sensitive instrumentation during aseptic procedures—including cell culture setup, media preparation, pharmaceutical weighing, and microbiological plating. The unit complies with YY 0569–2011 (China’s national standard for clean bench classification and performance verification) and is validated per GB/T 25220–2010 for airflow uniformity, microbial recovery efficiency, and structural integrity. Its design prioritizes operational stability, operator ergonomics, and long-term reproducibility in regulated laboratory settings.

Key Features

• Three-speed digital controller with intuitive touch interface—enables precise adjustment of airflow velocity to match procedural requirements.
• Programmable UV germicidal lamp (254 nm) with scheduled on/off functionality and real-time runtime logging for maintenance traceability.
• Motorized, counterbalanced sash system with infinite positioning capability—ensures consistent aerodynamic seal and minimizes turbulence at the work opening.
• Integrated air curtain protection along the front aperture—maintains laminar integrity even during active manipulation.
• Seamless AISI 304 stainless steel work surface—resistant to corrosion, autoclave-compatible, and compliant with cleaning validation protocols.
• Tempered glass side panels—provide full lateral visibility while maintaining structural rigidity and impact resistance.
• Dual-mode mobility system: swivel casters with locking brakes + independently adjustable leveling feet—facilitates both repositioning and permanent installation alignment.
• Interlocked LED lighting and UV irradiation circuits—prevents simultaneous operation to ensure operator safety and lamp longevity.
• Pre-filter access panel with quick-release mechanism—allows tool-free removal, washing, and reinstallation without disrupting cabinet calibration.
• Embedded runtime counters for fan motor, UV lamp, and HEPA filter—supports preventive maintenance scheduling and GLP-compliant recordkeeping.

Sample Compatibility & Compliance

The BLB-1000 is intended for use with non-toxic, non-volatile, and non-aerosol-generating materials. It is not suitable for handling infectious agents, radioactive isotopes, or volatile organic compounds. Its airflow architecture meets ISO 14644-1 Class 5 requirements for particle concentration (≤3,520 particles/m³ @ ≥0.5 µm), verified through standardized particle challenge tests. The unit satisfies YY 0569–2011 Annex D for clean bench classification and undergoes factory certification including airflow visualization (smoke test), velocity mapping (ISO 14644-3), and microbial challenge (settling plate assay yielding ≤0.5 CFU/plate·0.5 h). All electrical components conform to GB 4793.1–2007 (safety requirements for electrical equipment used in laboratory environments), and the enclosure design incorporates EMI shielding per GB/T 18268.1–2010.

Software & Data Management

While the BLB-1000 operates via embedded microcontroller-based hardware—not PC-dependent software—it provides auditable digital logs essential for quality systems. Runtime data for critical subsystems (fan, UV lamp, HEPA filter) are stored in non-volatile memory and displayed on the front panel LCD. These values support periodic review under GLP or ISO/IEC 17025 frameworks. Optional RS-485 communication interface (available upon request) enables integration into centralized facility monitoring systems for remote status reporting and alarm triggering. All firmware updates follow documented change control procedures, and calibration certificates include traceable NIST-traceable anemometer verification data.

Applications

• Aseptic preparation of cell culture media and reagents in academic and industrial life science labs.
• Handling of sterile pharmaceutical intermediates during formulation development and QC sampling.
• Microbiological plating and colony isolation in clinical diagnostic and food safety laboratories.
• Electronics assembly requiring particulate-free soldering or component placement.
• Calibration and handling of precision optical instruments sensitive to dust deposition.
• Preparation of reference standards and analytical standards in metrology laboratories.

FAQ

Is the BLB-1000 suitable for working with pathogenic microorganisms?
No. This is a clean bench—not a biological safety cabinet—and provides no personnel or environmental protection against biohazards.
What HEPA filter grade is installed, and how often should it be replaced?
An H14-grade HEPA filter (≥99.995% efficiency at 0.3 µm) is factory-installed. Replacement interval depends on usage intensity and ambient air quality; typical service life is 3–5 years, confirmed via differential pressure monitoring and post-replacement airflow verification.
Does the unit comply with FDA 21 CFR Part 11 requirements?
The BLB-1000 does not include electronic signature or audit trail features required for Part 11 compliance; however, its runtime logs may be manually transcribed into Part 11–compliant LIMS or ELN systems.
Can the BLB-1000 be installed in a cleanroom classified as ISO 7?
Yes. As a Class 5 local environment generator, it functions effectively within ISO 7 (Class 10,000) or cleaner ambient spaces, provided room-level HVAC maintains stable temperature, humidity, and positive pressure differentials.
Is third-party certification available for international markets?
CE marking is not applicable (as it is not an EU-directed device); however, IEC 61010-1 safety certification and ISO 14644-1 performance validation reports can be supplied upon request for import regulatory submissions.
