Erlab Captair 822 Smart Plug-and-Play Filtered Chemical Storage Cabinet

Overview

The Erlab Captair 822 Smart is a plug-and-play, ductless chemical storage cabinet engineered for safe, localized containment and continuous air purification in laboratories where permanent ducted exhaust infrastructure is unavailable or impractical. Unlike conventional ventilated cabinets relying on building exhaust systems, the Captair 822 Smart employs Erlab’s proprietary modular filtration architecture—comprising pre-filters, high-efficiency particulate arresters (HEPA), and chemically selective, impregnated activated carbon beds—to adsorb and neutralize volatile organic compounds (VOCs), acids, bases, aldehydes, and other hazardous vapors generated during storage of reagents and solvents. Its operation is based on recirculated airflow: ambient air is drawn through the cabinet interior, passed sequentially through layered filtration media, and returned to the lab environment at ≤1% residual contaminant concentration—verified via real-time breakthrough monitoring and validated against ISO 15195 reference methodologies. Designed specifically for low-to-moderate volatility chemical inventories (e.g., acetone, ethanol, HCl, ammonia, formaldehyde), it eliminates reliance on structural ventilation while maintaining operator exposure below OEL (Occupational Exposure Limit) thresholds under normal use conditions.

Key Features

• Smart Status Ring™ visual interface: A circumferential LED ring encircling the cabinet top provides immediate, color-coded status feedback—green (normal operation), amber (filter saturation warning), red (door open or airflow interruption)—enabling hands-free situational awareness without interrupting workflow.
• Real-time door position sensing: Integrated magnetic proximity sensors detect door opening/closing events and automatically modulate fan speed to maintain consistent face velocity (≥0.45 m/s) and containment integrity during access.
• Dual transparent swing-door configuration: Tempered safety glass doors offer unobstructed line-of-sight visibility, ergonomic access, and full frontal exposure for rapid inventory identification and retrieval; optional sliding-door variant available for space-constrained installations.
• Modular, field-replaceable filter cartridges: Three-stage filtration system—mechanical pre-filter (G4 class), HEPA H13 (99.95% @ 0.3 µm), and application-specific carbon media—installed as single-service units with RFID-tagged lifecycle tracking and auto-log timestamping upon replacement.
• Integrated mechanical safety lock: Key-operated deadbolt secures both doors simultaneously, compliant with institutional chemical security protocols and supporting GLP/GMP-controlled substance handling requirements.
• Universal power compatibility: Auto-ranging 100–240 V AC input with internal 24 V DC conversion ensures stable operation across global laboratory electrical standards without external transformers.

Sample Compatibility & Compliance

The Captair 822 Smart is validated for storage of Class I–III chemicals per NFPA 45 and GHS hazard categories, including flammable liquids (flash point < 60°C), corrosives, and health-hazardous substances with vapor pressures up to 10 kPa at 20°C. It is not intended for highly volatile, pyrophoric, or peroxide-forming compounds (e.g., diethyl ether, sodium metal, tert-butyl hydroperoxide). All filtration configurations undergo independent third-party testing per EN 14175-3 Annex D for containment efficiency (≥99.9% tracer gas retention) and EN 1822-1 for HEPA integrity. The unit carries CE marking under the EU Machinery Directive 2006/42/EC and Electromagnetic Compatibility Directive 2014/30/EU. Documentation packages include Factory Acceptance Test (FAT) reports, filter performance certificates, and traceable calibration records—fully auditable for ISO/IEC 17025-accredited labs and FDA-regulated environments operating under 21 CFR Part 11 data integrity guidelines.

Software & Data Management

While the Captair 822 Smart operates as a standalone, microcontroller-driven device without cloud connectivity, its embedded firmware supports local data logging via USB-C export (CSV format) of operational parameters: cumulative runtime, door-open event timestamps, fan speed history, and filter service intervals. The Smart Ring™ status history is retained for ≥12 months and synchronized with filter replacement logs to support preventive maintenance scheduling. For enterprise integration, Erlab’s optional Captair Connect gateway (sold separately) enables SNMP-based network monitoring, Syslog event forwarding, and compatibility with LabVantage, STARLIMS, and LabWare LIMS platforms—facilitating automated audit trails required under GLP and GMP compliance frameworks.

Applications

• Secure, localized storage of routine analytical reagents (HPLC solvents, titrants, buffers) in QC/QA laboratories with limited HVAC capacity.
• Point-of-use containment for teaching labs performing undergraduate organic chemistry experiments requiring frequent solvent access.
• Pharmaceutical R&D facilities managing intermediate compounds under controlled temperature and humidity conditions (when installed in climate-stable rooms).
• Hospital core labs storing diagnostic reagents—including formalin, glutaraldehyde, and xylene—where duct installation violates infection control architecture.
• Field-deployable research stations (e.g., environmental monitoring trailers, mobile testing units) requiring self-contained chemical management without fixed infrastructure.

FAQ

Does the Captair 822 Smart require external ductwork or make-up air systems?

No. It operates as a fully recirculating, ductless system with integrated filtration and does not connect to building exhaust or require dedicated make-up air.
How often must the filters be replaced?

Filter service intervals depend on chemical load and usage frequency; typical replacement is every 6–12 months. The Smart Ring™ and internal log provide predictive alerts based on cumulative airflow and detected VOC breakthrough thresholds.
Can this cabinet be used for storing flammable liquids?

Yes—when equipped with the optional explosion-proof fan kit (certified per ATEX II 2G Ex db IIB T4 Gb) and configured with flame-arresting carbon media, it complies with EN 14470-1 for flammable liquid storage up to 50 L total volume.
Is the unit compatible with laboratory information management systems (LIMS)?

Standalone operation includes USB data export; full LIMS integration requires the optional Captair Connect hardware module and API-enabled middleware configuration.
What documentation is provided for regulatory audits?

Each unit ships with a complete Technical File including Declaration of Conformity, FAT report, filter validation certificates, EMC test summaries, and traceable serial-number-matched calibration logs—all structured for direct submission during ISO 17025, CAP, or FDA inspections.
