Erlab GreenFumeHood 3 GFH3 6400 Ductless Fume Hood

Overview

The Erlab GreenFumeHood 3 GFH3 6400 is a high-performance, ductless fume hood engineered for precision chemical containment in modern laboratories where infrastructure constraints, energy efficiency, and operational flexibility are critical design criteria. Unlike conventional ducted hoods that rely on building exhaust systems, the GFH3 6400 employs Erlab’s proprietary multi-stage filtration architecture—based on over 50 years of molecular and particulate air purification expertise—to capture and neutralize airborne contaminants at the source. Its core principle centers on dynamic airflow management: ambient laboratory air is drawn across the work surface at a controlled face velocity of 0.4–0.6 m/s, passed through sequential filtration stages—including activated carbon, HEPA, and specialized Unisorb® chemisorbent media—and recirculated into the lab environment after verified removal of volatile organic compounds (VOCs), acids, bases, solvents, and fine particulates (down to 0.3 µm). This closed-loop operation eliminates reliance on external ductwork, significantly reducing HVAC load and associated energy consumption while maintaining full compliance with international safety standards for operator exposure limits.

Key Features

• All-steel construction with epoxy-powder-coated finish ensures structural integrity, corrosion resistance, and long-term durability under routine chemical exposure.
• SmartCommand™ control module provides real-time visual and audible status feedback—including filter saturation alerts, airflow deviation warnings, and operational mode confirmation—enabling proactive maintenance and uninterrupted workflow continuity.
• Modular Unisorb® filtration system supports customizable configurations for diverse chemical classes: standard, acidic, basic, or mixed-hazard applications; filters are field-replaceable without tools and require no recalibration post-installation.
• Integrated LED lighting delivers uniform, shadow-free illumination across the full work surface (≥500 lux at 75 cm height), meeting EN 14175-3 photometric requirements for visual task clarity and user fatigue reduction.
• Low-noise fan assembly operates below 55 dB(A) at 1 m distance, conforming to ISO 15714 acoustic benchmarks for non-disruptive laboratory environments.
• Compact footprint and standardized power interface (AC 220 V, 50/60 Hz) enable rapid deployment in retrofit labs, mobile units, teaching facilities, and cleanroom-adjacent zones where duct penetrations are prohibited or impractical.

Sample Compatibility & Compliance

The GFH3 6400 is validated for safe handling of liquid reagents, powdered solids, and low-volatility compounds commonly encountered in synthetic chemistry, pharmaceutical QA/QC, environmental testing, and academic research. It is not intended for perchloric acid, hydrofluoric acid, radioactive isotopes, or highly exothermic reactions exceeding manufacturer-specified thermal load thresholds. Performance validation follows EN 14175-3 Annex B (tracer gas containment test), ASTM E1192 (face velocity and airflow uniformity), and ISO 15714 (filter efficiency and breakthrough monitoring). All units undergo factory-certified type testing and include traceable calibration documentation aligned with GLP audit requirements. Optional data logging modules support 21 CFR Part 11-compliant electronic records for regulated environments.

Software & Data Management

The SmartCommand™ interface integrates seamlessly with Erlab’s CloudConnect™ platform (optional subscription), enabling remote monitoring of filter life, cumulative runtime, airflow stability, and alarm history across multi-unit installations. Local display provides intuitive icon-based navigation with multilingual UI (English, French, German, Chinese, Japanese). Audit-trail functionality logs all user interactions—including filter change events and parameter adjustments—with timestamp, operator ID, and action type. Exportable CSV reports facilitate integration into LIMS or EHS management systems. Firmware updates are delivered via secure OTA protocols compliant with IEC 62443-4-2 cybersecurity guidelines.

Applications

• Teaching laboratories requiring flexible, low-infrastructure chemical handling stations.
• Pharmaceutical development labs performing formulation screening, stability testing, and analytical sample prep under GMP-aligned conditions.
• University research facilities deploying modular lab layouts with frequent reconfiguration needs.
• Field-deployable labs and containerized testing units where external exhaust is unavailable.
• Quality control labs processing routine solvent-based extractions, titrations, or dilution series with minimal VOC generation.
• Microelectronics R&D environments demanding particle-free recirculated air adjacent to cleanrooms.

FAQ

What types of chemicals can be safely handled in the GFH3 6400?

The hood is certified for use with common organic solvents (e.g., acetone, ethanol, hexane), inorganic acids (HCl, HNO₃), bases (NaOH, NH₃), and low-to-moderate volatility compounds. A detailed chemical compatibility matrix is provided in the User Manual and updated quarterly via Erlab’s Technical Support Portal.
How often must the filters be replaced?

Filter service intervals depend on usage intensity and chemical profile. Typical replacement ranges from 6–24 months; SmartCommand™ calculates remaining service life based on real-time airflow resistance and cumulative exposure metrics.
Does the GFH3 6400 require external ducting or make-up air systems?

No. It operates as a fully self-contained recirculating unit with zero external exhaust requirements. No building modifications, roof penetrations, or dedicated make-up air ducts are needed.
Can the unit be integrated into a centralized lab monitoring system?

Yes. Optional Modbus RTU or Ethernet/IP communication modules support integration with BMS, LIMS, or custom dashboards for enterprise-wide lab safety oversight.
Is third-party certification available for regulatory submissions?

Erlab provides ISO/IEC 17025-accredited test reports upon request, including full EN 14175-3 validation data, filter breakthrough curves, and noise/acoustic certification—all traceable to national metrology institutes.
