Airs AIH1502 Benchtop Chemical Fume Hood

Overview

The Airs AIH1502 Benchtop Chemical Fume Hood is an engineered ductless containment solution designed specifically for the safe operation of analytical instruments—such as HPLC systems, mass spectrometers, ICP-OES units, and automated sample processors—that emit low-to-moderate levels of volatile organic compounds (VOCs), acids, or aldehydes during routine use. Unlike conventional ducted fume hoods requiring extensive HVAC integration and structural penetrations, the AIH1502 operates on a closed-loop recirculation principle: ambient air is drawn through a dual-stage filtration system (pre-filter + high-capacity activated carbon bed), purified, and returned to the laboratory environment. This architecture eliminates dependence on building exhaust infrastructure while maintaining operator exposure below OSHA PEL and ACGIH TLV thresholds under validated operating conditions. Its all-steel construction ensures mechanical stability, corrosion resistance, and compatibility with rigorous GLP/GMP laboratory environments.

Key Features

• Benchtop form factor optimized for integration beneath standard lab benches or adjacent to floor-standing instrumentation—no floor space compromise.
• Vertically sliding sash with synchronized lateral window translation: enables unobstructed front access while preserving containment integrity during instrument loading/unloading.
• Airs-Touch intelligent interface with real-time display of airflow velocity, filter saturation status, internal temperature, and relative humidity—data logged at 1-minute intervals.
• Dual-stage filtration module certified for >99.9% removal efficiency against common solvents (e.g., acetone, methanol, hexane, formaldehyde) per ISO 10965 Annex B test protocols.
• Low-noise EC centrifugal blower (≤52 dB[A] at 1 m) delivering stable 400–600 m³/h volumetric flow across variable filter load states.
• Integrated LED task lighting (500–600 lux at work surface) with glare-reducing diffuser and independent on/off control.
• Mobile application support (iOS/Android) enabling remote monitoring of operational parameters, filter life estimation, and maintenance alerts via encrypted TLS 1.2 connection.

Sample Compatibility & Compliance

The AIH1502 is validated for continuous-duty protection of instruments generating emissions within defined chemical classes: polar and non-polar VOCs, weak inorganic acids (e.g., dilute HCl, HNO₃), and low-volatility aldehydes. It is not intended for perchloric acid, hydrofluoric acid, radioactive aerosols, or nanoparticle-generating processes. Regulatory alignment includes conformance with EN 14175-7:2021 (performance testing of ductless hoods), ISO 10965:2022 (safety requirements and test methods), and Chinese national standard GB/T 35424–2017. Filter replacement logs and system calibration records are exportable in CSV format to support FDA 21 CFR Part 11-compliant audit trails when deployed in pharmaceutical quality control settings.

Software & Data Management

The embedded Airs-Touch OS supports local data persistence for ≥30 days of operational telemetry (airflow, temperature, humidity, filter delta-P). All parameter changes—including sash position adjustments and manual fan speed overrides—are time-stamped and user-ID tagged. Historical datasets can be exported via USB-C or secure Wi-Fi to LIMS-compatible platforms. The companion mobile application provides push notifications for filter end-of-life (±5% accuracy), abnormal pressure differentials (>15% deviation from baseline), and firmware update availability. No cloud storage is enabled by default; data residency remains fully on-premise unless explicitly configured by the lab administrator.

Applications

• Shielding HPLC autosamplers and detectors during solvent gradient elution.
• Enclosing benchtop FTIR or Raman spectrometers used with volatile sample preparation reagents.
• Protecting clinical chemistry analyzers (e.g., Roche Cobas, Siemens Atellica) from ambient VOC interference during calibration.
• Isolating GC-MS inlet systems during septum purge or liner cleaning procedures.
• Providing localized containment for microplate sealers, liquid handlers, and automated pipetting workstations in regulated diagnostic labs.

FAQ

What types of chemicals can the AIH1502 safely filter?
It is validated for organic solvents (acetone, ethanol, dichloromethane), weak acids (dilute acetic, nitric, hydrochloric), and low-concentration aldehydes. Strong oxidizers, HF, perchloric acid, and heavy metal vapors require alternative containment strategies.
How often must the filters be replaced?
Under typical usage (8 h/day, moderate VOC load), carbon filters require replacement every 6–12 months; pre-filters every 3 months. The system calculates remaining service life based on cumulative airflow and real-time adsorption saturation modeling.
Does it meet international safety certification requirements?
Yes—it complies with EN 14175-7:2021 and ISO 10965:2022 for ductless hood performance, including face velocity uniformity, containment leakage testing (<0.05 ppm tracer gas escape), and fire-retardant material specifications.
Can it be integrated into an existing LIMS or ELN platform?
Raw telemetry data (CSV/JSON) is exportable via USB or secure Wi-Fi. API integration is available under custom deployment agreements with documented OpenAPI 3.0 specifications.
Is external ventilation ductwork required?
No. The AIH1502 operates as a self-contained recirculating unit. No wall penetrations, roof stacks, or dedicated exhaust shafts are necessary.
