Kanomax Model 3080 Anderson Impactor Airborne Microbial Sampler

Overview

The Kanomax Model 3080 is a precision-engineered Anderson impactor-based airborne microbial sampler designed for quantitative assessment of viable microorganisms in controlled environments. It operates on the principle of inertial impaction: air is drawn at a calibrated flow rate of 100 L/min through a multi-stage, stainless-steel sampling head, where particles ≥0.6 µm are sequentially deposited onto standard agar-filled Petri dishes according to their aerodynamic size distribution. This validated physical separation mechanism ensures high collection efficiency and colony isolation fidelity—critical for regulatory-grade environmental monitoring in GMP, ISO 14644, and USP <797>/<800> compliant facilities. The instrument’s robust architecture, integrated ISO Class 3 exhaust filtration, and stainless-steel sampling head (autoclavable up to 121 °C) support repeatable, contamination-free operation across pharmaceutical cleanrooms, biosafety cabinets, hospital isolation rooms, and aseptic processing suites.

Key Features

• Calibrated constant-flow sampling at 100 L/min with real-time flow verification and ±2.5% accuracy per ISO 14698-1 and EN 13098 requirements
• Full-cycle programmability: user-defined sampling volume (20–6000 L), interval timing (10 s–1 h), delay start (up to 23 h 59 min), and cycle count (2–300) or continuous mode
• Intuitive 4.3-inch color touchscreen interface supporting multilingual operation (English, Japanese, Chinese) and on-device configuration of sampling location metadata, operator ID, and test notes
• Multi-level access control system enabling role-based permissions for operators, supervisors, and administrators—supporting audit-ready workflow governance
• Stainless-steel impactor head compatible with both 90–100 mm and 55–84 mm Petri dishes; fully autoclavable without disassembly
• Onboard data logging (10,000 records) with timestamped parameters: date/time, location tag, operator ID, sampled volume, cycle status, flow stability, and alarm events
• Dual power operation: rechargeable Li-ion battery (7 h runtime) and universal AC input (100–240 V); includes battery-level monitoring and low-power warning
• Integrated ISO Class 3 HEPA exhaust filter ensuring operator and ambient safety during active sampling

Sample Compatibility & Compliance

The Model 3080 is validated for use with conventional nutrient or selective agar media in standard Petri dishes (90–100 mm for general environmental monitoring; 55–84 mm for compact or portable applications). Its impactor geometry conforms to ISO 14698-1 Annex B and EU GMP Annex 1 recommendations for viable particle collection efficiency across the respirable and inhalable size ranges. All firmware and data handling routines comply with ALCOA+ principles. Audit trails—including user actions, parameter changes, and calibration events—are automatically recorded with immutable timestamps. Optional RS-485 Modbus RTU integration enables seamless connection to building management systems (BMS) or centralized environmental monitoring systems (EMS) for 21 CFR Part 11–compliant data aggregation and electronic signature workflows.

Software & Data Management

Data export is supported via USB mass storage in CSV format—structured to include sampling ID, start/stop timestamps, total volume, flow deviation logs, cycle index, and pass/fail flags per sampling event. Internal memory retains full operational logs, including battery charge cycles, error codes, and firmware version history. The device supports direct printing via optional thermal printer (sold separately) and remote control via infrared handheld transmitter for hands-free operation in glovebox or laminar flow hood environments. Firmware updates are performed offline using signed USB packages, preserving traceability and integrity under GLP/GMP conditions.

Applications

• Pharmaceutical manufacturing: routine monitoring of Grade A/B/C/D cleanrooms per ISO 14644-1 and EU GMP Annex 1
• Hospital infection control: surface-air correlation studies in operating theaters, isolation wards, and pharmacy compounding areas
• Food & beverage production: validation of HACCP critical control points and post-sanitization verification
• Biotechnology labs: biosafety cabinet certification (NSF/ANSI 49) and isolator environmental qualification
• Cultural heritage preservation: microbiological risk assessment in museum storage vaults and archival reading rooms
• Medical device manufacturing: ISO 13485 environmental control verification in Class 7–8 cleanrooms

FAQ

Is the Model 3080 compliant with ISO 14698-1 for bioaerosol sampling?
Yes—the instrument implements a six-stage Anderson impactor design with documented cut-off diameters and collection efficiencies aligned with ISO 14698-1 Annex B requirements for viable particle recovery.
Can sampling parameters be locked to prevent unauthorized modification?
Yes—administrator-level password protection enables parameter lockdown, including flow setpoint, volume limits, and cycle definitions, ensuring procedural consistency across shifts.
What is the recommended calibration frequency?
Kanomax recommends annual flow calibration against a NIST-traceable primary standard, with interim verification using a calibrated wet test meter before each critical sampling campaign.
Does the device support integration into an existing EMS platform?
Yes—via RS-485 Modbus RTU protocol, the Model 3080 transmits real-time flow status, sampling progress, and alarm states to supervisory SCADA or EMS software with configurable polling intervals.
How is data integrity maintained during USB export?
All exported CSV files include embedded digital signatures and checksums; file metadata preserves original acquisition timestamps and prevents manual tampering without detection in validated systems.
