BJBY FCC-5000H Intrinsically Safe Air Sampling Pump

Overview

The BJBY FCC-5000H Intrinsically Safe Air Sampling Pump is a portable, battery-powered sampling instrument engineered for quantitative collection of airborne contaminants—including gases, vapors, aerosols, and respirable or total particulate matter—in hazardous and non-hazardous environments. Designed in accordance with IEC 60079-0 and GB 3836.1–2010 standards for intrinsic safety, the FCC-5000H is certified for use in Zone 1 explosive atmospheres where flammable gases or vapors may be present during normal operation. Its core measurement principle relies on precision volumetric displacement via a brushless DC diaphragm pump, coupled with real-time digital flow regulation using a thermal mass flow sensor and closed-loop PID control architecture. This ensures stable, voltage- and backpressure-insensitive flow delivery across variable sampling conditions—critical for regulatory-grade occupational hygiene monitoring and environmental compliance workflows.

Key Features

• Intrinsically safe design certified for use in Class I, Division 1 / Zone 1 hazardous locations per national and international explosion-protection standards
• Dual selectable flow ranges: 100–3000 mL/min for low-flow sorbent tube sampling (e.g., benzene, formaldehyde) and 1000–5000 mL/min for high-flow filter-based particulate collection (e.g., metals, silica, PM fractions)
• Digital constant-flow control with ≤2% reproducibility and ≤5% stability over full operating temperature (−10 to 50°C) and pressure range
• Real-time on-screen display of elapsed time, programmed sampling duration, accumulated actual volume, standardized volume (corrected to 25°C, 101.325 kPa), ambient temperature, barometric pressure, and remaining battery capacity
• Integrated lithium-ion battery supporting >20 hours of continuous operation at mid-range flow settings; intelligent power management extends runtime under low-load conditions
• Compact, ergonomic form factor (122 × 60 × 72 mm) and ultra-lightweight construction (0.5 kg) enabling belt-mount, tripod-mount, or handheld deployment during personal or area monitoring
• Low acoustic signature (<60 dB[A]) suitable for quiet indoor environments and extended-shift worker-worn applications

Sample Compatibility & Compliance

The FCC-5000H is compatible with a broad spectrum of sampling media including charcoal tubes (NIOSH 1501), silica gel cartridges, XAD-2 resin tubes, mixed-bed sorbents, polycarbonate and PVC membrane filters (for metals analysis), and glass fiber filters (for gravimetric dust assessment). It meets the performance requirements outlined in JG 956–2013 (Verification Regulation for Air Samplers) and supports method-compliant execution of GBZ/T 192.3–2007 (Determination of Total Dust in Workplace Air) and related Chinese occupational exposure limit (OEL) protocols. While not pre-certified to ISO 13137 or EN 1232, its flow accuracy, timer resolution, and data integrity features align with GLP-aligned field practices required for audit-ready exposure assessments.

Software & Data Management

The device stores up to 99 complete sampling sessions locally, each containing start/stop timestamps, target and actual flow rates, corrected and uncorrected volumes, temperature and pressure readings, and battery status. Data export is performed via USB-C interface using vendor-provided PC utility software, which generates CSV-formatted reports compliant with internal QA/QC review and regulatory submission requirements. The firmware supports traceable user calibration through an open backend interface—enabling laboratory technicians to perform field verification and adjustment against NIST-traceable flow standards without requiring factory service. Audit trails include calibration event logs with date/time stamps and operator ID fields, supporting basic 21 CFR Part 11 readiness when deployed within controlled documentation systems.

Applications

• Occupational hygiene surveys: Personal and area monitoring of volatile organic compounds (VOCs), acid gases, aldehydes, and metal fumes in chemical plants, refineries, electroplating facilities, and semiconductor fabrication cleanrooms
• Industrial hygiene compliance: Routine OEL verification per GBZ 2.1–2019 and supplementary workplace air quality assessments
• Emergency response: Rapid deployment for post-incident vapor cloud characterization and confined-space entry verification
• Public health surveillance: Ambient air toxics monitoring near industrial perimeters, waste treatment sites, and transportation corridors
• Research-grade exposure modeling: Paired with real-time analyzers or offline GC-MS/LC-MS lab analysis for dose–response studies

FAQ

Is the FCC-5000H certified for use in ATEX or IECEx zones?
No—it complies with China’s GB 3836 series for intrinsic safety and is approved for Zone 1 use domestically, but does not carry ATEX or IECEx certification. Users requiring EU or international zone-rated equipment must verify local authority acceptance prior to deployment.
Can the instrument correct sampled volume to standard temperature and pressure (STP)?
Yes—it calculates and displays both actual (unadjusted) and standard-condition volume simultaneously, applying correction to 25°C and 101.325 kPa per GBZ/T 192.3–2007 conventions.
What maintenance is required to ensure long-term flow accuracy?
Annual verification against a primary flow standard is recommended; the built-in calibration interface allows users to perform two-point flow adjustments using certified calibrators such as dry calibrators or bubble meters.
Does the pump support external trigger inputs or analog output signals?
No—this model operates as a standalone sampling controller without industrial I/O interfaces. For automated system integration, contact BJBY technical support regarding OEM-compatible variants.
How is battery health monitored during extended field use?
The LCD shows real-time remaining capacity (%) and triggers visual/audible alerts at 15% and 5% thresholds; runtime estimates are dynamically updated based on current load and temperature.
