Kanomax 3000-0C Quantitative Respirator Fit Tester

Overview

The Kanomax 3000-0C is a quantitative respirator fit tester engineered for precision, regulatory compliance, and field-deployable robustness. It employs a real-time condensation nucleus counter (CNC) to measure ambient aerosol concentration both inside and outside the respirator during standardized test exercises—enabling calculation of the Total Inward Leakage (TIL) and fit factor (FF) with traceable metrological integrity. Unlike qualitative methods relying on subjective sensory response, the 3000-0C delivers objective, numerical pass/fail determinations aligned with ISO 16900-1:2019, OSHA 1910.134 Appendix A, CSA Z94.4–22, and China’s mandatory standards GB 2626–2019 and GB 19083–2010. Its core function is to verify whether a specific respirator model achieves sufficient facial seal across diverse anthropometric profiles—ensuring that workplace respiratory protection programs meet auditable GLP/GMP and occupational health requirements.

Key Features

• Real-time CNC-based aerosol counting: Measures ultrafine particles (≥10 nm) in ambient air without requiring challenge agents (e.g., saccharin, isoamyl acetate), eliminating consumables and operator exposure risk.
• Regulatory-grade quantitative output: Computes TIL (%) and fit factor (FF = 100/TIL) per test exercise—automatically aggregating results across eight required movements (normal breathing, deep breathing, turning head side-to-side, etc.) as defined in ISO 16900-1 and OSHA protocols.
• Dual-mode operation: Supports both standalone field use (via integrated touchscreen) and networked laboratory deployment (via Ethernet/Wi-Fi), with synchronized timestamping and audit-ready data export.
• Multi-respirator validation: Certified for testing disposable filtering facepiece respirators (FFRs) including N95, KN95, KP95, N100, and KN100 classifications, as well as reusable half-mask and full-facepiece elastomeric respirators and powered air-purifying respirators (PAPRs).
• Compliance-ready software architecture: Built-in data logging includes user ID, respirator model/lot, test date/time, environmental temperature/humidity, and individual exercise-level TIL values—structured for FDA 21 CFR Part 11–compliant electronic records when deployed with validated third-party LIMS or QMS platforms.

Sample Compatibility & Compliance

The 3000-0C is validated for use with all respirator types certified under national and international filtration standards—including NIOSH-approved N-, R-, and P-series, China’s KN/KP classifications per GB 2626–2019, and medical-grade surgical/protective masks per GB 19083–2010. It meets the minimum fit factor requirement of ≥100 (i.e., TIL ≤1%) for FFRs used in healthcare settings under GB 19083–2010 and supports the more stringent ≤2% TIL threshold for KN100/KP100 respirators. Device firmware and calibration procedures adhere to ISO/IEC 17025 traceability requirements through Kanomax’s JCSS-accredited calibration lab in Japan. All test reports generated are compatible with internal audit workflows and external regulatory inspections by CNCA, NIOSH, or provincial occupational safety authorities.

Software & Data Management

The instrument operates with embedded firmware supporting five language interfaces (English, Japanese, Simplified Chinese, Korean, German) and exports CSV- and PDF-formatted reports directly to USB storage or network shares. When connected to a host PC running Kanomax’s FitTest Manager software (v3.2+), users gain access to centralized multi-device monitoring, batch report generation, trend analysis across cohorts, and automated flagging of outliers exceeding ±15% inter-test coefficient of variation (CV). Audit trails record every configuration change, calibration event, and user login—enabling full reconstruction of test conditions per GLP Annex 11 and ISO 13485 documentation requirements. Raw particle count data (per second, per exercise phase) is retained for retrospective reanalysis without loss of resolution.

Applications

The 3000-0C serves as a critical verification tool across regulated environments where respiratory protection efficacy directly impacts human health outcomes. In hospitals and clinical laboratories, it validates fit for staff using N95/KN95 respirators during aerosol-generating procedures under GB 19083–2010 and CDC guidance. In manufacturing facilities—especially semiconductor, pharmaceutical, and battery production—it ensures worker compliance with OSHA Permissible Exposure Limits (PELs) for nanomaterials, metal fumes, and organic vapors. Fire departments and emergency response units deploy it for rapid pre-shift fit verification of SCBA and APR systems. Independent testing laboratories utilize its CNC stability for certification support per CNAS accreditation criteria (CNAS-CL01:2018), while occupational hygienists integrate its outputs into exposure assessment models per AIHA RP-1 and ISO 16877.

FAQ

Does the 3000-0C require challenge aerosols or consumables during operation?

No. It measures naturally occurring ambient ultrafine particles (10–1000 nm) using a thermally stabilized CNC sensor—eliminating need for artificial aerosols, filters, or chemical agents.
Can the device be used outdoors or in uncontrolled environments?

Yes, provided ambient particle concentration remains ≥1000/cm³ (verified automatically at startup); built-in environmental sensors monitor temperature, humidity, and barometric pressure to flag conditions outside ISO 16900-1 operational limits.
Is calibration traceable to national standards?

Yes. Factory calibration is performed against JCSS-certified reference instruments in Kanomax’s Tokyo metrology lab, with certificate-of-calibration included and annual recalibration recommended.
How does the 3000-0C handle data integrity for regulatory audits?

All test sessions generate immutable, time-stamped records with digital signatures; optional integration with validated QMS platforms enables full 21 CFR Part 11 compliance including electronic signatures and audit trail review.
What respirator types are explicitly validated for use with this model?

NIOSH-certified N95/N99/N100, GB 2626–2019 KN90/KN95/KN100/KP95/KP100, EN 149:2001+A1:2009 FFP2/FFP3, and CSA Z94.4–22 Class 2/Class 3 elastomeric half/full facepieces.
