Medical Face Mask Particle Protection Tester PMT-9500: Advanced Filtration Efficiency Testing for Re

Overview
The PMT-9500 is a cutting-edge system designed to evaluate the particle filtration efficiency (PFE) and breathability of medical face masks, respirators, and filtering facepiece devices (FFPs). Critical for manufacturers of surgical masks, N95 respirators, and pandemic-response PPE, this instrument ensures compliance with global standards (ASTM F2100, NIOSH 42 CFR Part 84, EN 14683) while delivering precise, real-time measurements of particle capture rates under simulated respiratory conditions.

Core Features

1. Adjustable Particle Challenge System:

• Generates polydisperse or monodisperse aerosols (0.1–10 µm) with adjustable concentrations (10⁴–10⁷ particles/cm³) using NaCl, DOP (oil), or latex spheres.
• HEPA-filtered inlet ensures contamination-free testing.

2. High-Precision Filtration Analysis:

• Laser photometer or piezoelectric sensors measure filtration efficiency (≥99.9% accuracy) and penetration rates (≤0.01% detection limit).
• Real-time data display with dynamic graphs for PFE vs. particle size curves.

3. Breathability Testing:

• Measures differential pressure (ΔP) across masks at flow rates up to 100 L/min to quantify breathability (EN 14683-compliant).

4. Automated Test Protocols:

• Preconfigured modes for ASTM F2100 (medical masks), NIOSH N95/KF94 (respirators), and ISO 29903 (respiratory devices).
• Customizable cycles for single-use or reusable mask testing.

5. User Safety & Hygiene:

• Fully enclosed chamber with HEPA filtration, UV-C sterilization, and touchless controls to prevent cross-contamination.

Technological Innovations

• AI-Powered Particle Tracking: Machine learning algorithms identify breakthrough patterns and predict long-term filter degradation.
• Dynamic Flow Stabilization: Self-adjusting valves maintain consistent airflow despite mask deformation or humidity changes.
• Modular Design: Swapable fixtures for testing diverse mask types (e.g., N95, KN95, cloth masks, valved respirators).

Applications

• Medical PPE Certification: Validate surgical masks and respirators for viral/bacterial filtration efficiency (VFE/BFE ≥99%).
• Industrial Safety: Test respirators for workers exposed to hazardous aerosols (e.g., welding fumes, silica dust).
• Pandemic Preparedness: Mass testing of COVID-19 masks and KN95 respirators for regulatory compliance.
• Academic Research: Study advanced materials like graphene-enhanced filters or electrostatic nonwovens.

Compliance & Certification
Fully compliant with:

• ASTM F2100 (Medical Face Masks)
• NIOSH 42 CFR 84 (Respirator Certification)
• EN 14683 (Surgical Masks)
• ISO 29904 (Respiratory Protective Devices)

Optional Accessories

• Multi-stage particle generators (dry/wet aerosols)
• High-flow pump (up to 300 L/min for coarse particle testing)
• Environmental chamber (-40–85°C, 0–95% RH)
• Automated report generator with FDA/EU MDR compliance templates

Conclusion
The PMT-9500 sets a new standard in particle protection testing by combining clinical-grade accuracy with AI-driven analytics. Manufacturers gain critical insights to optimize filter performance, accelerate certification, and meet evolving global safety demands—from pandemic-grade respirators to everyday medical PPE.
