Overview
The Kanomax 3910 is a high-flow, portable laser particle counter engineered for precision airborne particulate monitoring in regulated cleanroom environments and critical process areas. Based on the principle of single-particle light scattering (SPLS) using a stable 650 nm laser diode source, the instrument detects and sizes individual particles suspended in air by measuring the intensity and angular distribution of scattered light. Its 50 L/min volumetric flow rate enables rapid, statistically robust sampling—reducing measurement time by up to 75% compared to standard 28.3 L/min instruments—while maintaining full compliance with ISO 21501-4 for optical calibration, counting efficiency, and sizing accuracy. Designed for use in pharmaceutical manufacturing, biotechnology facilities, semiconductor fabrication, aseptic processing suites, and aerospace cleanrooms, the 3910 delivers real-time, multi-channel particle concentration data across six user-selectable size thresholds (0.3, 0.5, 1.0, 3.0, 5.0, and 10.0 µm), supporting immediate classification against ISO 14644-1:2015, EU GMP Annex 1, and USP limits.
Key Features
- High-flow sampling at 50 L/min with flow stability maintained within ±1 particle deviation per 5-minute interval—ensuring minimal statistical uncertainty in low-concentration environments.
- Six simultaneous particle size channels calibrated per ISO 21501-4, with counting efficiency of 50±20% at 0.3 µm and <15% sizing resolution error at both 0.3 µm and 0.5 µm.
- Integrated 6.4-inch full-color resistive touchscreen interface supporting multilingual operation (English/Chinese), intuitive navigation, and on-device pass/fail evaluation against ISO class limits.
- Built-in thermal printer enabling immediate generation of audit-ready test reports—including timestamp, location ID, operator name, environmental parameters (via optional sensors), and raw channel counts.
- Dual hot-swappable rechargeable lithium-ion batteries providing >4 hours of continuous operation; AC adapter included for benchtop or extended deployment use.
- Robust mechanical architecture (200 × 205 × 250 mm, ~5.0 kg) with IP54-rated enclosure, integrated isokinetic sampling probe, and 2-meter conductive sampling tube for laminar flow compatibility.
- Full 21 CFR Part 11 compliance mode with electronic signatures, role-based access control, audit trail logging, and secure data export via USB or Ethernet.
Sample Compatibility & Compliance
The Kanomax 3910 is validated for use with ambient air, compressed gases (with optional pressure regulator), and HEPA-filtered supply air streams. It meets the optical performance requirements of ISO 21501-4 for particle counters used in cleanroom certification and filter integrity testing. All measurement outputs comply with ISO 14644-1:2015 (cleanroom classification), ISO 14644-2:2015 (monitoring requirements), GB/T 16292–2010 (Chinese pharmaceutical cleanroom standard), and JJF 1190–2008 (national metrological verification regulation). When paired with optional environmental sensors (temperature, RH, differential pressure, and air velocity), it satisfies Annex 1 (2022) requirements for dynamic environmental correlation during Grade A/B zone qualification. Zero-count performance conforms to JIS B 9921, and coincidence loss remains below 5% at concentrations up to 150,000 particles/ft³—verified per ISO 21501-4 Annex C.
Software & Data Management
Data acquisition, analysis, and reporting are managed through Kanomax’s proprietary KAN-View software (included), which supports CSV, PDF, and XML export formats compatible with LIMS and MES platforms. The instrument stores up to 10,000 complete sampling records onboard—including date/time stamp, location code, operator ID, all six channel counts, environmental sensor readings (if connected), and pass/fail status per ISO class. External storage expansion is supported via USB flash drives (FAT32 formatted), enabling long-term trending and batch archival without PC dependency. Audit trails record all configuration changes, user logins, report generations, and calibration events—with timestamps traceable to UTC and digitally signed to meet GLP/GMP documentation integrity requirements.
Applications
- Cleanroom classification and routine monitoring per ISO 14644-1 and EU GMP Annex 1 in pharmaceutical sterile manufacturing zones (Grade A–D).
- HEPA and ULPA filter leak testing using scanning probe mode with real-time alarm thresholds for localized contamination events.
- Environmental monitoring programs (EMPs) in biologics fill-finish suites, isolators, and RABS systems requiring rapid, high-volume sampling.
- Validation of HVAC system performance during commissioning, qualification (IQ/OQ/PQ), and periodic requalification.
- In-process monitoring of semiconductor photolithography clean booths, microelectronics assembly lines, and medical device packaging rooms.
- Research-grade aerosol characterization in university clean labs, national metrology institutes, and aerospace contamination control studies.
FAQ
Does the Kanomax 3910 support remote data transfer via Ethernet?
Yes—the instrument features a 10/100 Mbps Ethernet port enabling TCP/IP communication with centralized monitoring systems, SCADA interfaces, or networked PCs running KAN-View.
Can the 3910 be used for compressed gas particle monitoring?
Yes—when configured with an optional pressure-regulated inlet module and stainless-steel sampling line, it complies with ISO 8573-1 for Class 1–5 compressed air purity testing.
Is firmware upgrade capability available in the field?
Yes—firmware updates are delivered via USB drive and installed directly through the touchscreen interface without requiring service engineer intervention.
What is the maximum allowable particle concentration before coincidence error exceeds specification?
Per ISO 21501-4, the 3910 maintains <5% coincidence loss up to 150,000 particles/ft³ and <10% up to 500,000 particles/ft³—validated with NIST-traceable PSL standards.
Does the built-in printer support custom report templates?
Yes—KAN-View allows users to define header/footer content, add company logos, select mandatory fields (e.g., ISO class, sampling duration, location), and generate PDF or printed output matching internal QA documentation standards.
