Overview
The Captair Chemtrap V 201 is an engineered under-counter ventilation and molecular filtration system designed exclusively for integration with standard chemical safety storage cabinets in laboratory and industrial environments. Unlike conventional ducted fume hoods or room exhaust systems, the Chemtrap V 201 operates on a closed-loop recirculation principle: it draws air from within the cabinet interior, passes it through a high-surface-area activated carbon-based molecular filter optimized for organic vapors (e.g., acetone, ethanol, toluene, chloroform), and returns purified air back into the laboratory space. This design eliminates the need for external ductwork while maintaining continuous air exchange—75 m³/h—ensuring volatile compounds are captured at the source before reaching operator breathing zones. Its compact footprint (200 × 537 × 605 mm) allows seamless installation beneath workbenches or adjacent to floor-mounted flammable liquid cabinets, supporting space-constrained facilities without compromising safety integrity.
Key Features
- Integrated axial fan with thermal protection and low-noise operation (55 dBA at 1 m), delivering stable 75 m³/h airflow across variable filter resistance.
- Molecular filter cartridge with engineered granular activated carbon and impregnated chemisorbents, providing selective adsorption of low-molecular-weight organic vapors per NFX 15-211 Class 2 performance criteria.
- Dual-stage safety monitoring: real-time fan operational status indicator plus visual/audible saturation alarm triggered when breakthrough detection thresholds are approached.
- Modular telescopic duct (1 m length, Ø80 mm) with adaptable flange interface (Ø75–110 mm) ensures compatibility with diverse cabinet vent ports across OEM brands.
- Energy-efficient operation (19 W nominal power draw) reduces HVAC load by recirculating tempered lab air instead of exhausting conditioned air outdoors—supporting ISO 50001-aligned energy management practices.
- Plug-and-play commissioning: no structural modification required; installation completed in under 15 minutes using supplied mounting hardware and electrical connection kit.
Sample Compatibility & Compliance
The Chemtrap V 201 is validated for use with steel-walled, FM- or EN 14470-1-certified flammable liquid storage cabinets containing solvents, reagents, and intermediate compounds commonly handled in QC/QA labs, R&D facilities, and pharmaceutical manufacturing suites. It does not replace primary fire-rated cabinet construction but augments containment by mitigating vapor accumulation during door opening events and long-term storage. Performance compliance is verified against French standard NFX 15-211 Class 2, which mandates that filtered emissions remain below 50% of the applicable Threshold Limit Value (TLV®–TWA) for each target compound. While TLVs are published by ACGIH® and adopted regionally (e.g., OSHA PELs in the U.S., MAK values in Germany), the system’s design margin supports alignment with GLP/GMP environmental monitoring expectations where ambient exposure control is documented as part of facility risk assessment (ISO 14644-1 cleanroom adjunct protocols, ICH Q5C stability chamber ancillary controls).
Software & Data Management
The Chemtrap V 201 is a standalone electromechanical device with no embedded microprocessor, firmware, or network connectivity. All operational feedback is delivered via discrete LED indicators and audible alerts—ensuring electromagnetic compatibility (EMC) in sensitive instrumentation zones and eliminating cybersecurity or validation overhead associated with regulated software. Filter service life tracking follows a time-based maintenance schedule (recommended replacement every 12 months under average loading conditions), supplemented by optional saturation verification using external handheld detection pumps and colorimetric probe rods (sold separately). No audit trail, electronic logs, or 21 CFR Part 11 compliance features are included, consistent with its classification as a passive engineering control rather than a regulated analytical instrument.
Applications
- Continuous vapor suppression in solvent storage cabinets located in analytical laboratories handling HPLC mobile phases, GC standards, and extraction solvents.
- Odor and exposure mitigation in university teaching labs where undergraduate students access shared chemical inventories.
- Supplemental vapor control for cabinets storing legacy reagents in aging infrastructure lacking centralized exhaust capacity.
- Temporary containment enhancement during facility renovations where ducted ventilation is unavailable or interrupted.
- Compliance support for ISO/IEC 17025-accredited testing labs documenting secondary engineering controls in their safety management system (clause 4.3.2).
FAQ
Does the Chemtrap V 201 eliminate the need for a dedicated exhaust system?
No—it is not a substitute for primary ventilation where regulatory requirements mandate ducted removal (e.g., perchloric acid, hydrogen sulfide, or highly toxic agents). It serves as a supplementary recirculating control for low-to-moderate volatility organics in general-purpose storage.
Can the filter be regenerated or refilled?
No. The molecular filter is a single-use, factory-sealed cartridge. Regeneration compromises adsorption kinetics and introduces cross-contamination risk; replacement is required per manufacturer guidelines.
Is the unit compatible with cabinets from non-Captair manufacturers?
Yes. The adjustable flange and telescopic duct accommodate standard vent port diameters (75–110 mm) found on major OEM cabinets including Justrite, Safetycabinet, and Brenntag-branded units.
What maintenance documentation is provided?
A printed Installation & Maintenance Manual (EN/FR/DE) includes torque specifications, filter replacement procedure, alarm interpretation chart, and NFX 15-211 test summary report. Digital copies are available upon request via Captair Technical Support.
Does the system meet UL or CE marking requirements?
The unit carries CE marking per EMC Directive 2014/30/EU and Low Voltage Directive 2014/35/EU. It is not UL-listed, as it falls outside the scope of UL 1275 (fume hood standards) due to its recirculating architecture.
