Overview
The Hujing FX-FH1200 is a fully steel, single-face laboratory fume hood engineered for reliable containment and safe handling of volatile, toxic, or odorous substances in academic, industrial, and quality control laboratories. It operates on the principle of constant-volume or variable-air-volume (VAV) airflow management—depending on configuration—to maintain a stable face velocity between 0.25 and 0.45 m/s across the sash opening. This velocity range complies with widely referenced safety standards including ANSI/ASHRAE 110-2016 and EN 14175-3:2021 for performance testing of fume hoods. The unit integrates water, electricity, gas, and exhaust services into a unified structural platform, enabling seamless workflow integration without compromising operator safety or environmental integrity.
Key Features
- Fully welded cold-rolled steel frame with electrostatic powder coating—providing corrosion resistance, smooth non-porous surfaces, and long-term dimensional stability under routine cleaning protocols.
- Stainless steel work surface (304 grade) with optional integrated sink basin—designed for chemical resistance and ease of decontamination following GLP-compliant procedures.
- Vertically sliding tempered glass sash with counterbalanced mechanism—allowing precise height adjustment to optimize containment while maintaining ergonomic access.
- Dedicated low-speed axial exhaust fan mounted at the top plenum—engineered for quiet operation (<65 dB(A)) and consistent static pressure compensation across varying duct configurations.
- Integrated utility panel featuring multiple grounded electrical outlets (IEC 60320 C13/C14), quick-connect water valves (brass body, EPDM seals), and standardized gas inlet ports (BS 341 or NPT threads).
- Energy-efficient 28 W T8 fluorescent lighting system with diffuser lens—delivering uniform illumination (>300 lux at work surface) without shadow interference during visual inspection or titration tasks.
Sample Compatibility & Compliance
The FX-FH1200 accommodates standard bench-scale apparatus including distillation setups, digestion blocks, open-vessel reactions, and weighing stations. Its 1030 mm wide work area supports dual-user coordination in teaching labs and fits common 1 L–5 L reaction vessels. The unit meets structural and functional requirements outlined in ISO 15195:2018 (laboratory ventilation systems), and its design facilitates audit readiness for ISO/IEC 17025:2017 and FDA 21 CFR Part 11 environments when paired with documented SOPs and preventive maintenance logs. Optional upgrades—including ductless carbon filtration modules and real-time face velocity monitoring sensors—are available to extend compliance scope for specific hazard classes (e.g., perchloric acid, hydrogen sulfide).
Software & Data Management
While the FX-FH1200 operates as a standalone mechanical system without embedded firmware, it supports integration into centralized building management systems (BMS) via analog 0–10 V or 4–20 mA output signals from optional airflow transducers. For laboratories requiring traceability, Hujing provides calibration certificates aligned with ISO/IEC 17025-accredited third-party verification services. All operational parameters—including sash position, average face velocity, and power consumption history—can be logged manually or via external data loggers compliant with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available).
Applications
- Chemical synthesis and reagent preparation in university research labs.
- pH adjustment, sample digestion, and solvent evaporation in environmental testing facilities (e.g., EPA Method 3050B, ASTM D3682).
- Pharmaceutical QC workflows involving raw material handling per USP Analytical Instrument Qualification guidelines.
- Electroplating bath maintenance and metal ion analysis where acid mists require continuous extraction.
- Veterinary diagnostic labs performing histopathology staining with xylene-based solvents.
FAQ
Is the FX-FH1200 certified to any international safety standards?
Yes—it is designed and tested in accordance with ANSI/ASHRAE 110-2016 and EN 14175-3:2021 for face velocity uniformity, containment efficiency, and airflow visualization.
Can this fume hood be installed without external ductwork?
No—the FX-FH1200 is a ducted (exhaust-type) fume hood and requires connection to a dedicated exhaust system with appropriate static pressure rating and corrosion-resistant ducting.
What maintenance intervals are recommended for optimal performance?
We recommend quarterly inspection of sash balance mechanism, annual verification of face velocity distribution using ASHRAE 110 tracer gas test protocol, and biannual replacement of fluorescent lamp ballasts if operated continuously.
Does the unit include airflow alarms or digital monitoring?
Standard configuration includes no built-in alarm; however, optional add-ons such as differential pressure switches and LED-based velocity indicators are available upon request.
Is stainless steel sink installation included in the base model?
The stainless steel sink is an optional accessory—listed separately in quotation documentation—and requires additional cutout planning during initial installation.
