AIRTECH HVS Series Vertical Laminar Flow Clean Benches

Overview

The AIRTECH HVS Series Vertical Laminar Flow Clean Benches are engineered for reliable personnel- and product-protective containment in non-sterile aseptic applications across pharmaceutical QC laboratories, biotechnology research facilities, and clinical diagnostic environments. Operating on the principle of unidirectional vertical laminar airflow—generated by a high-efficiency particulate air (HEPA) filter (≥99.995% @ 0.3 µm)—the system delivers ISO Class 5 (Federal Standard 209E Class 100) clean air uniformly across the work surface. Unlike horizontal flow benches, the vertical configuration minimizes operator exposure to recirculated air while maintaining consistent downflow velocity profiles critical for particle removal efficiency. Each unit is designed and validated in accordance with YY/T 1539–2017, the Chinese national standard for medical-grade clean benches, and holds a registered Class II medical device license under China’s National Medical Products Administration (NMPA), affirming its suitability for regulated healthcare-related workflows.

Key Features

• Vertically oriented HEPA-filtered laminar airflow ensures continuous, uniform downflow at controlled velocity—optimized for particle entrainment and removal from the working area.
• Motorized, infinitely adjustable sash system enables precise ergonomic positioning without mechanical resistance or positional drift; integrated sensors verify sash height for interlocked safety functions.
• One-piece seamless 304 stainless steel work surface with forward-curved ergonomic contour reduces wrist strain and facilitates rapid decontamination—no crevices or welded seams to harbor microbial growth.
• Full-color LCD touchscreen interface provides real-time monitoring of inflow velocity (m/s), HEPA filter differential pressure, UV lamp operational status, and active fault codes—with audible and visual alerting.
• VAV-controlled EC centrifugal blower maintains stable airflow across variable sash positions while reducing power consumption up to 35% compared to fixed-speed AC systems.
• Hardwired safety interlocks prevent simultaneous activation of UV germicidal lamps and sash movement, and disable UV output when sash exceeds safe operating height—fully compliant with IEC 61000-6-4 and YY/T 1539–2017 electrical safety requirements.

Sample Compatibility & Compliance

The HVS Series accommodates standard Petri dishes, multi-well plates, flasks, pipette racks, and small-scale bioreactors within its defined working envelope (defined by model-specific internal dimensions: HVS-1000-U: 1000 mm W × 600 mm D × 700 mm H; HVS-1300-U: 1300 mm W × 600 mm D × 700 mm H; etc.). Units are certified to YY/T 1539–2017 for medical clean bench performance—including microbial challenge testing, airflow visualization (smoke studies), and filter integrity verification (DOP/PAO scanning). While not classified as biological safety cabinets (BSCs), these clean benches meet ISO 14644-1:2015 for airborne particulate cleanliness and support GLP-compliant documentation through optional audit-trail-enabled firmware upgrades. They are not intended for handling volatile toxic compounds or aerosol-generating procedures requiring personnel protection beyond ISO Class 5 environments.

Software & Data Management

The embedded control firmware supports time-stamped event logging—including sash position changes, UV cycle initiation/completion, filter pressure deviation alarms, and manual override events. Logged data is exportable via USB port in CSV format for integration into laboratory information management systems (LIMS) or quality documentation archives. Optional firmware version 2.1+ includes configurable user access levels (operator, supervisor, administrator), electronic signature capability per FDA 21 CFR Part 11 Annex A guidelines, and automated calibration due-date reminders aligned with internal SOPs. All units ship with a factory-verified traceable calibration certificate referencing NIST-traceable anemometry and photometric light intensity standards.

Applications

• Aseptic preparation of culture media, reagents, and dilutions in microbiology and cell culture laboratories.
• Handling of non-hazardous sterile components during medical device assembly and packaging validation.
• Quality control testing of pharmaceutical excipients and finished dosage forms where ISO Class 5 environmental control is mandated.
• Preparation of samples for downstream analytical instrumentation—including HPLC autosampler vial loading, GC sample introduction, and spectrophotometric cuvette filling.
• Supporting ISO 13485-certified manufacturing processes requiring documented environmental controls for Class I and IIa medical devices.

FAQ

What regulatory standards does the HVS Series comply with?
It conforms to YY/T 1539–2017 (China’s medical clean bench standard), ISO 14644-1:2015 (cleanroom classification), and IEC 61000-6-4 (EMC immunity). It holds a Class II medical device registration certificate issued by China’s NMPA.
Is this unit suitable for handling hazardous biological agents?
No. The HVS Series is a clean bench—not a biological safety cabinet—and provides no personnel or environmental protection against biohazards, toxins, or volatile chemicals.
Can the airflow velocity be calibrated onsite?
Yes. The unit includes a built-in anemometer port compatible with NIST-traceable handheld probes; calibration procedures are documented in the user manual and supported by AIRTECH technical service bulletins.
What maintenance intervals are recommended for HEPA filters?
Filter replacement frequency depends on ambient particulate load and usage hours; typical service life ranges from 18 to 36 months. Differential pressure monitoring and annual integrity testing (via PAO/DOP scan) are required per YY/T 1539–2017.
Does the system support network connectivity or remote monitoring?
Standard configuration includes local USB data export only. Ethernet or RS-485 interfaces are available as factory-installed options upon request, enabling integration with building management systems (BMS) or centralized lab monitoring platforms.
