YINHEKEJI FCG-5 Intrinsically Safe Portable Air Sampling Pump

Overview

The YINHEKEJI FCG-5 Intrinsically Safe Portable Air Sampling Pump is an ATEX- and IECEx-compliant sampling instrument engineered for quantitative collection of airborne contaminants—including respirable dust, volatile organic compounds (VOCs), acid gases, metal fumes, and other hazardous vapors—in high-risk environments. Designed in accordance with the fundamental principles of volumetric displacement sampling, the FCG-5 employs a brushless DC diaphragm pump coupled with precision-calibrated laminar flow elements and real-time microprocessor-based flow regulation. Its intrinsic safety certification (Ex ib IIB T3 Gb) ensures operational reliability in Zone 1 and Zone 2 hazardous locations—such as petrochemical refineries, pharmaceutical cleanrooms with solvent handling, grain silos, underground mining operations, and confined-space entry zones—where flammable gas or vapor concentrations may approach lower explosive limits (LEL). The device operates without spark-generating components, thermal runaway mitigation, and current-limited circuitry compliant with IEC 60079-11, making it suitable for continuous personal exposure monitoring (PEM) and fixed-point industrial hygiene sampling per OSHA Method 0500, NIOSH Method 0600, and ISO 16000-2.

Key Features

• Intrinsically safe design certified to Ex ib IIB T3 Gb per IEC 60079-0 and IEC 60079-11—validated for use in gas groups IIB (e.g., ethylene) and temperature class T3 (surface max. temp. ≤200 °C).
• Triple-range selectable flow control: (50–500) mL/min for low-flow sorbent tube sampling (e.g., charcoal tubes per NIOSH 1501); (200–1500) mL/min for mixed-phase aerosol collection; and (1000–5000) mL/min for high-volume particulate filtration (e.g., PVC or PTFE membrane cassettes).
• Integrated anti-backflow protection system prevents condensate or particulate ingress into the pump head—reducing maintenance frequency and extending service life beyond 5000 hours under rated load conditions.
• High-strength AS/ABS polymer housing with conformal coating for moisture resistance, ESD shielding, and mechanical impact resilience (IK07-rated enclosure).
• Rechargeable 7.4 V / 2.3 Ah lithium-ion battery enabling ≥12 hours of uninterrupted operation at 1 L/min against 35 kPa vacuum load—fully compatible with GLP/GMP field workflows requiring unbroken chain-of-custody timing.
• Programmable timer with 1-minute to 99-hour 59-minute resolution and ≤0.1% drift—supports multi-shift exposure profiling, automated start/stop, and pause/resume functionality without interrupting accumulated runtime logs.

Sample Compatibility & Compliance

The FCG-5 is validated for use with standard 37-mm and 47-mm filter cassettes (e.g., MCE, PVC, PTFE), glass sorbent tubes (e.g., Tenax TA, Carbopack), impingers (e.g., midget impingers per OSHA ID-121), and diffusion samplers. It meets mechanical and electrical requirements for sampling per ISO 13137 (pumps for personal sampling of airborne chemicals), EN 1232 (pumps for workplace air sampling), and GB/T 17061–1997 (Chinese national standard for air-sampling instruments). Its flow stability (≤±5% over 1 h) and metering accuracy (<±2.5% FS) satisfy data quality objectives (DQOs) outlined in EPA Compendium Method TO-17 and EU Directive 2004/107/EC for heavy metal speciation. All firmware and hardware configurations are traceable to factory calibration certificates issued under ISO/IEC 17025-accredited processes.

Software & Data Management

While the FCG-5 operates as a standalone, self-contained unit with no embedded Bluetooth or Wi-Fi interfaces—consistent with intrinsic safety architecture—it supports full auditability via time-stamped LCD display logs and external calibration verification records. Each unit ships with a factory-issued calibration report documenting flow verification at three points across each range using a NIST-traceable primary standard (e.g., dry calibrator per ISO 6145-2). Users may archive timer settings, runtime totals, and battery cycle counts manually in laboratory notebooks compliant with 21 CFR Part 11 Annex 11 requirements when paired with electronic lab notebook (ELN) systems. Optional third-party data loggers (e.g., GasBadge Pro-compatible modules) may be integrated externally via analog voltage output (0–5 V) for centralized telemetry in fixed-site deployments.

Applications

• Personal exposure monitoring (PEM) for occupational health compliance (OSHA PELs, ACGIH TLVs®) across chemical manufacturing, paint spraying, welding, and battery recycling facilities.
• Indoor air quality (IAQ) assessment in schools, hospitals, and office buildings—particularly for formaldehyde, benzene, and PM_2.5 source apportionment studies.
• Emergency response sampling during HAZMAT incidents involving chlorine, hydrogen sulfide, or ammonia releases—leveraging rapid deployment, lightweight portability (0.5 kg), and cold-start capability down to −10 °C.
• Research-grade atmospheric chemistry sampling in mobile laboratories or remote field stations where grid power is unavailable and explosion risk cannot be mitigated by ventilation alone.
• Regulatory stack testing support—when used with calibrated rotameters and certified sampling trains per EPA Method 5 and ISO 9096.

FAQ

Is the FCG-5 certified for use in Zone 0 hazardous areas?
No. The Ex ib IIB T3 Gb rating qualifies it for Zone 1 and Zone 2 only. Zone 0 requires Ex ia certification, which this model does not hold.

Can the flow rate be calibrated in the field without sending the unit to a service center?
Yes—users may perform two-point verification using a NIST-traceable electronic bubble flowmeter or dry calibrator. Full recalibration requires authorized service due to sealed sensor compensation algorithms.

Does the instrument meet FDA 21 CFR Part 11 requirements for electronic records?
The FCG-5 itself does not generate electronic records; however, its time-stamped manual logs and associated calibration documentation fully satisfy Part 11 predicate rule requirements when managed within a validated ELN or LIMS environment.

What is the recommended maintenance interval under daily field use?
Inspect inlet filters and anti-backflow valves every 50 operating hours; replace pump diaphragm and check valves every 2000 hours or per visual wear assessment—documented in accordance with ISO 17025 internal audit protocols.

Is the battery replaceable by the end user?
Battery replacement must be performed by an authorized YINHEKEJI service technician to maintain intrinsic safety integrity and explosion-proof housing certification. Unauthorized disassembly voids all certifications.
