YINHEKEJI FCS-30 Non-Explosion-Proof Dust Sampler

Overview

The YINHEKEJI FCS-30 Non-Explosion-Proof Dust Sampler is a portable, battery-powered gravimetric sampling instrument engineered for quantitative assessment of airborne particulate mass concentration in occupational and environmental settings. It operates on the principle of constant-flow air aspiration through a pre-weighed filter membrane—typically mixed cellulose ester (MCE) or polyvinyl chloride (PVC)—followed by post-sampling gravimetric analysis in accordance with standardized methods such as ISO 7708:1995 (airborne particles — size-selective sampling criteria for inhalable, thoracic and respirable fractions) and NIOSH Method 0500/0600. The device maintains a user-selected flow rate within defined tolerances during the entire sampling period, ensuring compliance with regulatory requirements for time-weighted average (TWA) and short-term exposure limit (STEL) assessments. Designed for field deployment in non-hazardous atmospheres, the FCS-30 is not certified for use in Class I, Division 1 or ATEX Zone 0/1 environments.

Key Features

• Intuitive LCD interface with menu-driven navigation and real-time display of operating parameters including elapsed time, remaining battery voltage, current flow rate, and pump status
• Precision electronic timer with programmable sampling duration from 1 minute to 99 hours and 59 minutes, supporting single-run, delayed-start, and multi-segment protocols
• Dual power configuration options: high-capacity lithium-ion battery pack (4500 mAh) paired with either a low-noise diaphragm pump (DC 11.1 V, ≥4 h continuous operation) or an energy-efficient rotary vane pump (DC 7.4 V, ≥8 h continuous operation)
• Robust mechanical architecture with compact footprint (205 × 135 × 115 mm) and lightweight design (2.5 kg), optimized for extended field use and operator portability
• Integrated battery monitoring system providing visual indication of charge level, charging progress, and low-voltage warning prior to cutoff
• Acoustically damped pump assembly delivering <75 dB(A) operational noise—suitable for indoor workplace monitoring without disruptive interference

Sample Compatibility & Compliance

The FCS-30 supports both total dust and respirable dust sampling configurations. Total dust collection is performed using a standard 37-mm or 25-mm cassette with a conductive or non-conductive filter medium (e.g., PVC, MCE, or PTFE), mounted on the included total dust sampling head. For respirable fraction measurement, an optional cyclone separator (e.g., GK2.69 or IOM design) may be coupled to the inlet to achieve aerodynamic cut-points aligned with ISO/CEN/ACGIH conventions. All sampling procedures adhere to GLP-aligned documentation practices, with traceable timing and flow records suitable for inclusion in industrial hygiene reports submitted to OSHA, HSE, or local regulatory authorities. While the instrument itself does not carry CE marking or intrinsic safety certification, its operational parameters meet the performance benchmarks outlined in GB/T 20964–2007 (Chinese national standard for dust samplers) and are compatible with ISO 8508:2021 (air quality — performance characteristics of instruments for measuring mass concentration of airborne particles).

Software & Data Management

The FCS-30 operates as a standalone hardware platform with no embedded firmware-based data logging or USB/Wi-Fi connectivity. All operational data—including start/stop timestamps, set flow rate, actual measured flow (via built-in flow sensor), and battery telemetry—are visually recorded by the user during field deployment and transcribed manually into laboratory notebooks or digital spreadsheets. This analog workflow ensures full auditability and eliminates potential software validation burdens under FDA 21 CFR Part 11 or EU Annex 11 frameworks. For laboratories requiring automated data capture, external flow calibrators (e.g., DryCal or Bios International units) may be used in tandem to verify and document flow stability before and after each sampling event, satisfying QA/QC requirements for accredited environmental testing facilities.

Applications

• Workplace exposure monitoring in manufacturing, mining, construction, and pharmaceutical production facilities
• Educational demonstrations in university-level occupational health, environmental science, and industrial hygiene curricula
• Baseline ambient particulate surveys in urban, rural, and peri-industrial zones
• Pre- and post-engineering control evaluations (e.g., ventilation upgrades, enclosure modifications)
• Respirable crystalline silica (RCS) monitoring where cyclone-equipped sampling is required per OSHA Silica Standard (29 CFR 1926.1153)
• Validation of personal protective equipment (PPE) effectiveness under real-world usage conditions

FAQ

Is the FCS-30 certified for use in explosive atmospheres?
No. The FCS-30 is explicitly designated as a non-explosion-proof instrument and must not be operated in classified hazardous locations per IEC 60079 or NEC Article 500.
What filter types and diameters are compatible with this sampler?
Standard 37-mm or 25-mm circular filters are supported; common media include PVC (for gravimetric analysis), PTFE (for subsequent elemental analysis), and mixed cellulose ester (for microscopy). Filter cassettes must be pre-conditioned and pre-weighed in a temperature- and humidity-controlled balance room.
Can the instrument maintain constant flow across variable filter loading?
Yes—the integrated feedback-controlled pump system compensates for increasing filter resistance up to the specified vacuum pressure limit (>2500 Pa), maintaining flow stability within ±5% over the full sampling duration.
Does the FCS-30 include calibration traceability documentation?
The unit ships with a factory calibration certificate referencing flow verification against a NIST-traceable primary standard. Users are responsible for periodic recalibration using a secondary standard (e.g., bubble meter or electronic calibrator) at intervals defined by internal QA policy or regulatory mandate.
What maintenance is required for long-term reliability?
Routine inspection of pump seals, filter holder O-rings, and battery contacts is recommended every 6 months. Diaphragm pumps require replacement of the membrane every 1,000 operating hours; rotary vane pumps require oil replenishment and filter cleaning per manufacturer guidelines.
