Kanomax AccuFIT 9000 Respirator Fit Tester

Overview

The Kanomax AccuFIT 9000 is a quantitative respirator fit testing system engineered for precision, regulatory compliance, and operational efficiency in occupational health and safety programs. It employs the condensation particle counter (CPC) method—a scientifically validated, real-time aerosol-based technique—to measure the inward leakage of ultrafine particles (0.02–1.0 µm) during wearer movement and breathing exercises. Unlike qualitative methods relying on subjective taste or smell perception (e.g., saccharin or Bitrex®), the AccuFIT 9000 delivers objective, numerical fit factors (FF) derived from the ratio of ambient particle concentration (C_out) to intramask concentration (C_in). This principle aligns with the fundamental requirement of ISO 16900-1:2015 and ASTM F1885–22 for quantitative fit testing, ensuring traceable, repeatable, and auditable results essential for OSHA 1910.134, CSA Z94.4, and GB 2626–2019 compliance.

Key Features

• High-sensitivity CPC detection enabling measurement across the critical respirable particle range (0.02–1.0 µm), including nanoparticles relevant to viral aerosols and combustion byproducts.
• Integrated dual-flow architecture: 100 cm³/min sampling flow for precise intramask measurement and 700 cm³/min total flow for stable challenge aerosol generation using ≥99.5% isopropanol or ethanol.
• 7-inch full-color touchscreen interface with six-language support (English, Chinese, Japanese, French, Spanish, Portuguese), designed for intuitive navigation without external peripherals.
• Preloaded test protocols aligned with OSHA, CSA, ANSI/AIHA Z88.10, UK HSE, and Chinese national standards (GB 19083–2010, GB 2626–2019, GB/T 32610–2016), allowing immediate deployment in multinational or regulated environments.
• Multi-unit network capability: A single Windows PC (Windows 7/8/10, .NET Framework 3.5) can coordinate up to four AccuFIT 9000 units concurrently—ideal for high-throughput industrial hygiene screening.
• Robust connectivity suite including USB, Ethernet, and Wi-Fi for secure data export, remote diagnostics, and integration into enterprise EHS management systems.

Sample Compatibility & Compliance

The AccuFIT 9000 supports quantitative fit testing across the full spectrum of tight-fitting respiratory protection devices. Validated configurations include N95 filtering facepiece respirators (FFRs), elastomeric half-masks and full-facepieces, powered air-purifying respirators (PAPRs), supplied-air respirators (SARs), self-contained breathing apparatus (SCBA), and chemical cartridge respirators from major manufacturers (3M, Honeywell, MSA, Scott, HSP). All testing adheres to the procedural rigor defined in ISO 16900-3:2016 (test panel requirements), ANSI/ASSP Z88.10–2022 (performance criteria), and FDA-recommended validation practices for medical device PPE assessment. The system’s calibration traceability follows NIST-traceable CPC reference standards, supporting GLP-compliant documentation and audit readiness under 21 CFR Part 11 when paired with validated software configurations.

Software & Data Management

The proprietary AccuFIT Test Manager software provides centralized control, real-time visualization of fit factor trends, and automated pass/fail determination per selected standard. Each test session generates timestamped, user-identified records stored locally or exported directly to Microsoft Excel (.xlsx) format—enabling seamless import into LIMS or corporate HRIS platforms. Audit trails capture operator ID, device serial number, test protocol version, environmental conditions (temperature/humidity), and raw C_out/C_in time-series data. Data integrity safeguards include password-protected configuration changes, electronic signatures for report finalization, and optional encryption for USB/U-disk transfers—meeting baseline requirements for ISO/IEC 17025 accreditation and internal quality assurance reviews.

Applications

• Hospital infection control programs verifying N95 FFR fit for frontline staff during pandemic response and routine airborne pathogen preparedness.
• Manufacturing and construction sites conducting annual or task-specific respirator certification per OSHA 1910.134(k) and GB 2626–2019 Clause 6.3.
• National metrology institutes and third-party certification bodies performing interlaboratory comparisons and proficiency testing.
• Respirator manufacturers executing design verification and batch conformance testing against GB 19083–2010 and EN 149:2001+A1:2009.
• Fire departments and hazardous materials response teams validating SCBA and APR performance under dynamic exertion protocols.

FAQ

What particle generation agent is required for AccuFIT 9000 operation?

Isopropanol or ethanol with purity ≥99.5% is used as the working fluid for aerosol generation via the built-in atomizer—no external nebulizers or hazardous challenge agents are needed.
Does the system require annual recalibration?

Yes. Kanomax recommends annual verification of CPC sensitivity and flow rate accuracy using NIST-traceable reference instruments; full recalibration is performed at authorized service centers.
Can test data be integrated with existing EHS software platforms?

Yes. CSV and Excel exports support ingestion into common EHS platforms (e.g., Intelex, Sphera, ETQ Reliance); API-level integration is available under custom support agreements.
Is the AccuFIT 9000 suitable for field use outside climate-controlled labs?

It operates reliably within 10–35°C and 20–85% RH (non-condensing), making it deployable in on-site industrial hygiene assessments, mobile testing vans, and emergency response staging areas.
How does the system handle mask seal leakage during head movement?

The test protocol includes seven standardized exercises (e.g., normal breathing, deep breathing, turning head side-to-side) per OSHA Appendix A, with continuous CPC monitoring capturing transient leaks that static tests would miss.
