Description

Technical Parameters

The High-Efficiency Particulate Respirator provides certified respiratory protection against toxic solid particles, aerosolized liquids, welding fumes, and fine particulate matter down to 0.3 microns.

Key Features

01/

99.95% Filtration Efficiency
Captures fine dust, metal fumes, and airborne solid particles down to 0.3 microns.

02/

Liquid Silicone Face Seal
Hypoallergenic elastomer provides an airtight facial seal to prevent air leakage during prolonged work shifts.

03/

Dual Bayonet Connection
Quick-lock twist mechanism ensures fast and secure attachment of replacement filter cartridges.

04/

Downward Exhalation Valve
Directs exhaled heat and moisture downward to reduce internal humidity and prevent safety eyewear fogging.

05/

4-Point Head Harness
Distributes weight evenly across the crown of the head to maintain secure positioning during heavy manual labor.

Applications & Limitations

Applications

Welding & Metal Fabrication: Protection against zinc oxide fumes, iron dust, and heavy metal smoke.
Construction & Demolition: Filtration of crystalline silica dust, stone cutting debris, and concrete grinding particulates.
Mining & Mineral Processing: Shielding against coal dust, quartz particles, and dry industrial mineral powders.
Facility Maintenance: Handling fiberglass, insulation wool, and non-volatile dust environments.

Limitations

Do not use in atmospheres containing less than 19.5% oxygen.
Unsuitable for organic vapors, acid gases, or volatile chemical solvents unless attached with combination gas/particulate filter cartridges.

Compatible Filters & Accessories

P3 Particulate Filter Cartridges: Encapsulated filter discs for solid and liquid aerosol capture.
P100 Filter Discs: Lightweight exposed filter pads designed for restricted working spaces.
Pre-Filter Cotton Pads: Outer disposable pre-filters to capture coarse debris and extend main filter lifespan.
Combination Gas & Dust Cartridges: Dual-purpose filters for simultaneous chemical vapor and particulate defense.
Replacement Strap Assemblies: Spare head harness and buckle sets for scheduled maintenance.

Use & Maintenance

Fitting & Seal Check: Position mask over the nose and mouth, pull the harness over the head crown, and latch the neck strap. Conduct positive and negative pressure seal checks prior to entering contaminated zones.

Cleaning & Sanitizing: Remove filter cartridges before washing. Submerge the facepiece in warm water below 50°C using neutral soap, rinse thoroughly under clean running water, and air dry in a clean environment.

Storage Conditions: Store in a cool, dry location away from direct sunlight, grease, and chemical solvent vapors.

Filter Replacement: Replace filter cartridges immediately when breathing resistance increases noticeably or when the filter media shows physical damage.

FAQ

Q: What is the main advantage of choosing a reusable elastomeric respirator over disposable masks?

A: Reusable respirators achieve a superior facial seal with lower inward leakage rates (<2% versus <8% for disposable options). Replacing only the filter cartridges reduces ongoing consumable costs and decreases solid waste generation.

Q: What technical standards do these particulate filters comply with?

A: Filters are tested in accordance with EN 143:2000+A1:2006 for P3 R classification, delivering filtration performance of ≥99.95% against solid dusts and liquid-based aerosols.

Q: Can the facepiece be cleaned and sanitized repeatedly?

A: Yes, liquid silicone rubber withstands repeated washing with warm water and neutral detergents without hardening, cracking, or losing seal flexibility.

Q: What customization options are available for private label and OEM partners?

A: Available options include custom mask body colors, pad-printed brand logos on filter housings, custom printed cartons, and altered head harness configurations.

Q: How is batch quality verified prior to shipment?

A: Each production lot undergoes automated filter penetration tests using sodium chloride and oil aerosol testing equipment, alongside exhalation valve leak checks. A batch certificate of analysis is supplied with every shipment.
