Overview
The IFC-2 Intrinsically Safe Dust Sampler is a portable, battery-powered air sampling instrument engineered for quantitative collection of airborne particulate matter in hazardous environments. It operates on the principle of isokinetic sampling with dual-head configuration—supporting both total dust and respirable fraction separation according to the British Medical Research Council (BMRC) inhalability curve (ISO 7708:1995). Designed for compliance with IEC 60079-0 and IEC 60079-11 standards, the unit features intrinsic safety certification ibI (150 °C), enabling safe deployment in Zone 1 and Zone 2 areas where explosive gas atmospheres (Group IIA–IIB, T1–T4) may be present—particularly underground mining, chemical processing plants, metallurgical facilities, and power generation sites. Its core architecture integrates a high-torque vane-type vacuum pump delivering stable negative pressure (>2500 Pa), precision analog flow control circuitry, microcontroller-based timing logic, and a sealed, ruggedized aluminum alloy housing rated IP54 for dust resistance and moisture protection.
Key Features
- Intrinsically safe design certified to ibI (150 °C), compliant with EN/IEC 60079-11 for use in explosive atmospheres
- Dual sampling head configuration: standardized total dust inlet and cyclonic respirable dust separator meeting BMRC cut-point criteria (50% cutoff at 4 µm aerodynamic diameter)
- Wide adjustable flow range: 5–25 L/min with analog fine-tuning and real-time visual feedback via integrated rotameter (Class 2.5 accuracy per ISO 5167)
- Stable flow performance: ≤5% deviation over 30-minute continuous operation under variable backpressure conditions
- Microprocessor-controlled timer with 0–99 min setting range and ±0.1% timing accuracy
- High-capacity rechargeable Li-ion battery (7.2 V / 3.5 Ah), supporting >180 minutes of uninterrupted sampling at 20 L/min
- Low acoustic signature: <55 dB(A) at 1 m distance, suitable for personal monitoring without operator disturbance
- Compact ergonomic form factor (210 × 130 × 90 mm; 2.6 kg) with integrated handle and tripod mount interface
Sample Compatibility & Compliance
The IFC-2 accommodates standard 40 mm diameter membrane filters (e.g., PVC, mixed cellulose ester, or PTFE) housed in reusable stainless-steel filter cassettes. The included impactor plates and silicone grease ensure consistent particle impaction efficiency across the respirable size range. All wetted components are chemically inert and compatible with gravimetric analysis per ISO 7708, NIOSH Method 0600, and OSHA ID-142. Device construction adheres to ATEX Directive 2014/34/EU and GB 3836.4–2021 (China’s national standard for intrinsic safety). Leak integrity is verified at 1000 Pa differential pressure with no detectable loss—ensuring measurement validity per ISO 13137:2013 (Workplace air — Requirements for pumps and flow rate meters).
Software & Data Management
While the IFC-2 operates as a standalone hardware sampler without embedded data logging, it supports full traceability in GLP/GMP-regulated workflows. Each unit ships with calibration documentation traceable to national metrology institutes and includes audit-ready accessories: calibrated flow verification ports, NIST-traceable stopwatch for field timing validation, and factory-certified flow charts. Optional external digital flow calibrators (e.g., DryCal® DC-Lite) can be interfaced for pre- and post-sampling verification. All operational parameters—including start time, duration, nominal flow rate, and environmental conditions (recorded manually or via companion environmental logger)—are documented in accordance with ISO/IEC 17025 requirements for accredited laboratories.
Applications
- Occupational hygiene monitoring in coal mines, metal ore extraction, and tunneling operations
- Respirable crystalline silica (RCS) assessment in foundries, abrasive blasting, and stone cutting
- Process-related dust emission evaluation in cement kilns, biomass combustion, and pharmaceutical powder handling
- Compliance testing against permissible exposure limits (PELs) defined by OSHA, MSHA, and China’s GBZ 2.1–2019
- Baseline exposure characterization during hazard communication (HazCom) and risk assessment under ISO 45001
FAQ
What explosion protection category does the IFC-2 meet?
It is certified as intrinsically safe “ibI” per IEC 60079-11, rated for Group I mining applications and surface industrial Zones 1 & 2.
Can the IFC-2 be used for PM2.5 or PM10-specific sampling?
No—it implements the BMRC respirable convention (not ISO/CEN PM definitions); for regulatory PM2.5/PM10 monitoring, refer to EN 12341-compliant sequential samplers.
Is the flow rate electronically compensated for temperature/pressure changes?
No—flow is manually stabilized using the analog regulator and verified with a primary calibrator before and after sampling; users must apply volumetric correction per ISO 5167 Annex C.
Does the device include built-in data storage or Bluetooth connectivity?
No—this is a purpose-built analog sampler optimized for reliability and intrinsic safety; digital telemetry would compromise Ex certification.
What filter media are recommended for gravimetric analysis?
40 mm PVC filters (e.g., SKC PVC-250) or mixed cellulose ester membranes (MCE), preconditioned and desiccated per ISO 11997-1 procedures.
