Kanomax 3715-06 / 3715-06D Remote Airborne Particle Counter

Overview

The Kanomax 3715-06 and 3715-06D are compact, networked airborne particle counters engineered for continuous, real-time environmental monitoring in cleanrooms, controlled manufacturing environments, pharmaceutical production suites, and HVAC validation systems. Based on calibrated laser diode light-scattering detection, these instruments quantify suspended particulate matter in ambient or ducted air streams across six discrete size channels—0.3, 0.5, 1.0, 3.0, 5.0, and 10.0 µm—with counting efficiency certified to ISO 21501-4 and JIS B 9921. Unlike portable handheld units, the 3715 series is designed for permanent installation and remote supervision, supporting unattended operation over extended periods. Its integrated vacuum pump delivers a stable 2.83 L/min (0.1 CFM) sampling flow, ensuring metrologically traceable volumetric throughput per ISO 21501-4 Annex B. The dual-model architecture distinguishes the base 3715-06 (RS-485/Modbus RTU) from the 3715-06D (enhanced with Ethernet-based Modbus TCP/IP and optional Wi-Fi connectivity via dock), enabling flexible integration into distributed SCADA, BMS, or centralized environmental monitoring systems (EMS).

Key Features

• Laser-based optical sensing with Class 2 laser diode (IEC 60825-1 compliant), rated for ≥10,000 hours of continuous operation and contributing to an overall MTBF of ≥10 years
• Simultaneous six-channel particle sizing and counting at 0.3–10.0 µm, meeting regulatory expectations for ISO Class 5–8 cleanroom classification per ISO 14644-1
• Internal vacuum pump with 8,000-hour service life; eliminates dependency on external air compressors or pressurized supply lines
• Multi-mode power compatibility: supports Power over Ethernet (IEEE 802.3af), AC 100–240 V, DC 12–24 V, and industrial-grade switch-mode power supplies
• 4.3-inch resistive touchscreen interface with local configuration, alarm threshold setting, and real-time channel-specific count rate visualization
• Configurable alarm logic (ON/OFF) across all six size bins, with user-defined thresholds from 0% to 100% of preset limits
• Onboard data logging capacity of 4,320 timestamped records, each containing full 6-channel counts, flow status, pump pressure, and optional temperature/humidity values

Sample Compatibility & Compliance

The 3715-06/06D is validated for use with ambient indoor air, HEPA-filtered cleanroom air, and low-velocity ducted airstreams. It is not intended for high-humidity (>85 % RH), corrosive, or oil-laden gas matrices. All calibration and performance verification follow Kanomax’s internal procedures aligned with ISO 21501-4, with traceability to NIST-traceable PSL reference standards. Device firmware and data handling protocols support audit readiness for regulated industries: raw count data includes embedded timestamps, instrument ID, and operational metadata required under FDA 21 CFR Part 11 for electronic records and signatures (when deployed with compliant EMS software). The unit complies with CE marking requirements (EMC Directive 2014/30/EU and Low Voltage Directive 2014/35/EU) and meets RoHS 2011/65/EU material restrictions.

Software & Data Management

Data export is supported via ASCII-formatted CSV files retrieved over USB or serial connection, or streamed in real time via Modbus registers. When connected to a central server using Modbus TCP/IP (3715-06D), the device transmits structured telemetry—including cumulative counts per channel, sampling duration, flow deviation alerts, and pump health indicators—at user-configurable intervals (1 sec to 60 min). Optional Kanomax KAN-LOG software provides trend analysis, pass/fail reporting against ISO 14644-1 limits, and automated PDF report generation. For GxP environments, integration with validated third-party EMS platforms (e.g., Siemens Desigo CC, Rockwell FactoryTalk, or TrackWise) enables full electronic audit trail, user access control, and change management logs.

Applications

• Cleanroom environmental monitoring (ISO 14644-1 classification and routine surveillance)
• Pharmaceutical aseptic processing line qualification and ongoing verification
• Medical device packaging area air quality assurance
• Microelectronics fab tool exhaust and make-up air monitoring
• HVAC system filter integrity testing and airflow uniformity mapping
• Research laboratories requiring long-term, unattended particulate trend analysis

FAQ

What communication protocols does the 3715-06D support for integration into a Building Management System (BMS)?
The 3715-06D supports Modbus TCP/IP natively over Ethernet and can be configured as a slave device with standard register mapping for particle counts, flow status, alarm states, and environmental sensor outputs.
Can the internal pump be replaced in the field, and what is the recommended maintenance interval?
Yes—the vacuum pump module is a field-replaceable unit. Kanomax recommends inspection every 6,000 operating hours; replacement is advised at 8,000 hours or if flow deviation exceeds ±5 % of nominal 2.83 L/min.
Is temperature and humidity measurement available as a built-in option or only via external sensors?
The 3715-06D model supports optional integrated temperature and relative humidity sensing (±0.5 °C, ±3 % RH accuracy) when ordered with the TH module; otherwise, external analog or digital sensors may be connected via configurable analog input terminals.
Does the device meet FDA 21 CFR Part 11 requirements for electronic records?
The hardware itself does not enforce Part 11 controls—but its deterministic data structure, immutable timestamps, and consistent Modbus register addressing enable compliant implementation when paired with a validated application layer (e.g., EMS with audit trail, electronic signature, and role-based access control).
What is the maximum allowable sampling distance between the inlet and the instrument when using external tubing?
For optimal counting accuracy and minimal particle loss, Kanomax specifies a maximum inlet tubing length of 2 meters using conductive 4-mm ID PTFE or stainless-steel tubing, with bends limited to ≤3 right-angle turns and no sharp kinks.
