Overview
The Erlab Captair 321 Smart is a certified ductless fume hood engineered for precision chemical containment and indoor air quality preservation in modern laboratories. Unlike conventional ducted hoods that exhaust conditioned air outdoors—imposing significant HVAC load—the Captair 321 Smart employs a closed-loop recirculation system with multi-stage filtration to capture and neutralize airborne contaminants at the source. Its operational principle relies on laminar face velocity control (0.4–0.6 m/s), verified via real-time airflow monitoring, combined with a dual-filter architecture: a pre-filter for particulates and a high-capacity activated carbon filter matrix tailored for organic vapors, acids, and low-concentration solvents. Designed and validated in accordance with international performance standards—including SEFA 9 (2022), NF X15-211 (2020), BS 7989:2001, and JG/T 385–2012—the unit delivers consistent containment efficiency (>99.9% for specified challenge agents per EN 14175-3 testing protocols) without requiring external ductwork or structural modifications.
Key Features
- Modular, field-replaceable filter cartridge system with RFID-tagged life-cycle tracking and automatic saturation alerts via eGuard™ cloud interface
- Bypass-intake design ensures stable face velocity across variable ambient conditions, minimizing turbulence and cross-contamination risk
- Polypropylene (PP) monolithic construction provides full resistance to corrosion from acids, bases, and halogenated solvents
- Integrated LED lighting (≥500 lux at work surface) with glare-free optical diffusers and independent switch control
- Height-adjustable sash with motorized lift mechanism (1107–1289 mm range) enabling ergonomic adaptation for seated or standing operation
- eGuard Smart Monitoring: Real-time display of filter status, airflow deviation, power consumption, and historical usage logs accessible via web dashboard or mobile app
Sample Compatibility & Compliance
The Captair 321 Smart is validated for routine handling of low-to-moderate volatility chemicals including acetone, ethanol, methanol, hydrochloric acid (≤10%), nitric acid (≤5%), and formaldehyde solutions (≤1%). It is not intended for perchloric acid, hydrogen fluoride, radioactive isotopes, or nanoparticle synthesis. All filtration media comply with EN 1822-1:2022 (filter classification) and ASTM D5212 (carbon adsorption capacity testing). The unit carries CE marking under EU Machinery Directive 2006/42/EC and conforms to ISO 15195:2018 for laboratory ventilation equipment certification. Full traceability documentation—including factory test reports, filter media CoA, and third-party containment validation summaries—is provided with each shipment to support GLP/GMP audit readiness.
Software & Data Management
eGuard™ is a secure, browser-based platform compliant with FDA 21 CFR Part 11 requirements for electronic records and signatures. It enables role-based access control, automated filter replacement scheduling, and exportable CSV/PDF reports for maintenance history and environmental compliance. Audit trails record all user actions—including sash position changes, alarm acknowledgments, and firmware updates—with timestamped digital signatures. Data residency options include AWS EU Frankfurt or on-premise server deployment. Integration with LabVantage LIMS and Siemens Desigo CCMS is supported via RESTful API and Modbus TCP protocols.
Applications
This hood serves as a primary containment solution in academic teaching labs, QC/QA environments for pharmaceutical excipient analysis, environmental testing facilities performing EPA Method 8270 derivatization, and R&D labs conducting small-scale synthetic chemistry. Its compact footprint (0.5 m² floor area) and plug-and-play installation make it suitable for modular lab reconfigurations, mobile laboratories, and cleanroom-adjacent spaces where duct routing is prohibited. The zero-exhaust design aligns with LEED v4.1 BD+C IEQ Credit 5 (Indoor Air Quality Assessment) and supports institutional net-zero energy targets by eliminating conditioned air loss.
FAQ
What types of chemicals can be safely used in the Captair 321 Smart?
It is validated for common organic solvents, dilute mineral acids, and aldehydes; consult the Erlab Chemical Compatibility Matrix before use with halogenated or oxidizing agents.
How often must filters be replaced?
Filter service intervals depend on usage intensity and chemical profile—typically 6–12 months; eGuard calculates remaining life based on real-time adsorption modeling.
Does the unit require external exhaust ducting?
No. It operates as a fully self-contained recirculating system with no connection to building HVAC or external vent stacks.
Can it be relocated within the lab after initial installation?
Yes. Its integrated casters, single-phase 230 V / 50 Hz input, and lightweight PP chassis (31.7 kg) allow safe manual repositioning without technical support.
Is remote monitoring available outside the local network?
Yes—eGuard supports secure TLS 1.3 encrypted access from any internet-connected device with authenticated credentials.
