Overview
The Erlab GreenFumeHood 6400 is a high-efficiency, ductless recirculating fume hood engineered for chemical containment and indoor air quality preservation in modern research and quality control laboratories. Unlike conventional ducted hoods that exhaust conditioned air to the exterior—resulting in substantial HVAC load and energy loss—the GreenFumeHood 6400 employs a closed-loop airflow architecture grounded in validated sorption kinetics and real-time face velocity monitoring. Air is drawn across the work surface at a consistent, operator-adjustable inflow velocity (typically 0.45–0.55 m/s per EN 14175-3), passes through a dual-stage Unisorb™ filtration module housed within the canopy, and is returned to the laboratory environment as chemically purified air. This design eliminates reliance on external ductwork, structural penetrations, or dedicated make-up air systems—making it especially suitable for retrofit installations, modular labs, and facilities with strict architectural or regulatory constraints on exhaust emissions.
Key Features
- Fully welded steel enclosure with epoxy-powder-coated finish for corrosion resistance and cleanability
- Single-face workstation configuration optimized for benchtop integration and space-constrained environments
- Dual-stage Unisorb™ filtration system: primary bed of impregnated activated carbon for broad-spectrum organic vapors (e.g., acetone, ethanol, toluene, chloroform), secondary bed of acid-gas-specific sorbent (e.g., for HCl, HNO₃, HF, SO₂, NH₃)
- Real-time filter saturation monitoring via integrated pressure differential sensors and LED status indicators; optional Bluetooth-enabled filter life tracking with predictive replacement alerts
- Face velocity sensor with digital display and audible/visual alarms for low-flow conditions (±5% accuracy per ISO 15755)
- No external ducting required—reduces installation time by up to 70% versus traditional hoods and avoids HVAC rebalancing
- Compliant with recirculation-specific safety benchmarks: EN 14175-3 Annex C, ISO 15755 Clause 6.4, and GB/T 24819–2009 for ductless operation in China
Sample Compatibility & Compliance
The GreenFumeHood 6400 is validated for safe handling of over 700 chemical substances across IARC Group 1–3 classifications, including halogenated solvents, aromatic hydrocarbons, aliphatic ketones, strong mineral acids, caustic alkalis, and low-molecular-weight amines. It is not intended for use with perchloric acid, hydrogen sulfide, radioactive materials, or nanoparticles requiring HEPA-level particulate capture. All filtration performance data are generated per ISO 15755:2021 test protocols using tracer gas challenge methods (e.g., isopropanol, sulfur dioxide). The unit meets GLP-relevant documentation requirements for filter change logs, airflow calibration records, and maintenance history—supporting audit readiness under ISO/IEC 17025 and FDA 21 CFR Part 11 when paired with Erlab’s optional LogBook Pro software.
Software & Data Management
While the base GreenFumeHood 6400 operates as a standalone hardware platform, optional connectivity modules enable integration into centralized lab infrastructure. The LogBook Pro desktop application (Windows/macOS) supports automated logging of filter usage hours, face velocity calibration events, alarm history, and user-defined SOP checklists. Audit trails are timestamped, user-ID stamped, and exportable in CSV/PDF formats compliant with ALCOA+ principles. For enterprise deployment, API access allows synchronization with CMMS platforms (e.g., IBM Maximo, UpKeep) and LIMS systems via HTTPS RESTful endpoints—facilitating preventive maintenance scheduling and regulatory reporting workflows.
Applications
- Routine analytical chemistry workflows involving solvent evaporation, titration, and reagent dispensing
- Pharmaceutical QC labs performing USP residual solvent testing preparation
- Academic teaching labs where infrastructure flexibility and operational cost control are prioritized
- Biotechnology R&D spaces requiring rapid reconfiguration between cell culture and small-molecule synthesis tasks
- Government and contract testing laboratories maintaining ISO/IEC 17025 accreditation without dedicated mechanical shafts
FAQ
Does the GreenFumeHood 6400 require external exhaust ducting?
No. It operates as a fully recirculating system; no wall or roof penetrations are needed.
How often must the Unisorb™ filters be replaced?
Filter service intervals depend on usage intensity and chemical profile; typical range is 6–18 months. Real-time monitoring prevents breakthrough via differential pressure thresholds.
Can this hood be used with perchloric acid?
No. Perchloric acid applications require a dedicated wash-down hood with stainless-steel construction and water mist suppression—this model is not rated for such use.
Is third-party validation data available for filtration efficiency?
Yes. Erlab provides ISO 15755-compliant test reports for 22 representative chemicals upon request, including breakthrough curves and adsorption capacity metrics.
What electrical requirements does the unit have?
Standard 100–240 V AC, 50/60 Hz, 1.2 A max; no special circuitry or grounding beyond standard lab-grade outlets.
