Hanuo SW-CJ-2D Vertical Laminar Flow Clean Bench

Overview

The Hanuo SW-CJ-2D Vertical Laminar Flow Clean Bench is an ISO Class 5-certified laboratory containment system engineered to deliver a localized, particle-free working environment for non-hazardous applications requiring microbiological or particulate control. Operating on the principle of unidirectional vertical laminar airflow—generated by a high-efficiency particulate air (HEPA) filter (≥99.99% @ 0.3 µm)—this clean bench directs filtered air downward at a controlled, uniform velocity across the work surface. Unlike biological safety cabinets, the SW-CJ-2D does not recirculate air nor provide personnel or environmental protection against biohazards; instead, it is purpose-built to safeguard samples and processes from ambient airborne contamination. It is widely deployed in cell culture preparation, sterile media handling, pharmaceutical quality control testing, semiconductor component assembly, and optical calibration workflows where sample integrity—not operator protection—is the primary objective.

Key Features

• Vertical laminar airflow architecture with pre-filter + HEPA filtration (EN 1822-compliant), ensuring consistent ISO Class 5 (100) cleanliness at ≥0.5 µm particle size per Fed. Std. 209E.
• Dual-operator configuration with 1150 mm wide work area, optimized for collaborative benchtop procedures without cross-contamination risk between users.
• Adjustable air velocity control (0.3–0.6 m/s) via infrared remote interface, enabling real-time optimization for varying procedural requirements—e.g., low-velocity settings for delicate tissue handling, higher velocities for rapid particulate clearance.
• Tempered glass front sash with semi-closed design minimizes turbulent ingress while maintaining ergonomic access and visual monitoring of operations.
• Electropolished 304 stainless steel work surface resists corrosion, facilitates decontamination, and complies with ISO 14644-1 surface roughness requirements for cleanroom-compatible materials.
• Integrated dual 2 kW grounded outlets (IEC 60320 C13), positioned within the work zone to power incubators, pipette controllers, or analytical balances without cable clutter or extension risks.
• LED status indicators and soft-start fan control reduce mechanical stress and extend HEPA filter service life; noise emission remains ≤58 dB(A) under full-load operation.

Sample Compatibility & Compliance

The SW-CJ-2D supports open-vessel procedures involving non-volatile, non-toxic reagents—including agar plate inoculation, PCR setup, microinjection, and precision weighing of reference standards. It is not rated for use with volatile organic compounds, radionuclides, or pathogenic agents requiring biosafety level (BSL) containment. The unit meets structural and performance criteria aligned with ISO 14644-1 (airborne particle concentration), ISO 14644-3 (testing methods), and EN 12464-1 (lighting for indoor workplaces). Its microbial performance (≤0.5 CFU/plate·hr using 90 mm TSA plates) satisfies routine environmental monitoring protocols under EU GMP Annex 1 and USP for non-sterile compounding environments. Documentation includes factory-verified airflow mapping reports and filter certification data traceable to ISO 17025-accredited test labs.

Software & Data Management

As a Class I passive containment device, the SW-CJ-2D operates without embedded software or network connectivity. All operational parameters—including fan speed, illumination status, and filter runtime—are monitored via physical controls and visual indicators. For laboratories implementing electronic recordkeeping under FDA 21 CFR Part 11 or EU Annex 11, manual log entries (e.g., daily airflow verification, filter replacement dates, and microbial monitoring results) must be maintained in validated laboratory information management systems (LIMS) or paper-based GLP-compliant logs. Optional external digital anemometers (NIST-traceable) may be used for periodic velocity validation and audit-ready reporting.

Applications

• Cell culture setup and passaging in academic and contract research organizations (CROs)
• Preparation of sterile culture media and antibiotic stock solutions in QC microbiology labs
• Assembly and inspection of MEMS devices and photonic components in clean manufacturing pilot lines
• Standardization of reference material dispensing for ISO/IEC 17025-accredited calibration labs
• Non-GLP botanical extract handling and solvent evaporation in natural product chemistry
• Training environments for aseptic technique instruction under controlled, reproducible conditions

FAQ

Does the SW-CJ-2D provide protection against biological hazards?

No. This is a clean bench—not a biological safety cabinet—and offers no personnel or environmental protection against aerosolized pathogens or toxins.
What maintenance intervals are recommended for the HEPA filter?

Filter replacement is typically required every 12–18 months under continuous operation, contingent upon upstream pre-filter condition and ambient particulate load; pressure differential monitoring is advised.
Can this unit be installed in a non-ISO classified room?

Yes, though background room air quality directly impacts achievable cleanliness; optimal performance requires installation in ISO Class 8 (100,000) or better ambient environments.
Is the unit compatible with 230 V / 60 Hz power supplies?

No. The SW-CJ-2D is configured for AC 220 V / 50 Hz only; voltage conversion or frequency adaptation requires external engineering review and is not supported by the manufacturer.
Does the unit include validation documentation for GxP environments?

Factory test reports (airflow uniformity, particle count, noise, illumination) are provided; IQ/OQ protocol templates and third-party qualification support are available upon request.
