Description

Technical Parameters

The Industrial Air-Purifying Respirator features a liquid silicone sealing facepiece with an ergonomic inner nose cup that prevents seal leakage and internal lens fogging. Equipped with a dual-bayonet cartridge interface and a multi-channel exhalation system, this mask maintains stable protection and reduced air resistance in contaminated environments.

Key Features

Liquid Silicone Face Seal: Molded from soft liquid silicone rubber to prevent skin irritation and ensure continuous airtight contact across diverse facial structures.

Quarter-Turn Bayonet Mount: Dual-filter bayonet structure allows swift and secure lock-in attachment for filter cartridges and particulate pre-filters.

Low-Resistance Exhalation Valve: Expels air directly downward, reducing moisture retention and internal heat buildup during extended working shifts.

4-Point Elastic Head Harness: Adjustable high-density nylon straps balance mask weight evenly to remove pressure points on the nose and cheeks.

Speech Diaphragm Unit: Integrated audio transmission membrane enables distinct vocal communication without compromising mask seal integrity.

Design & Components

01/

Silicone Facepiece Skirt: Hypoallergenic, non-deforming liquid silicone shell engineered to withstand chemical splash and temperature fluctuations.

02/

Filter Locking Interface: Dual bayonet structural connection compatible with standardized industrial particulate and gas cartridges.

03/

Valve Assembly: Dual inhalation non-return valves and a single downward exhalation valve disc made from heat-resistant silicone rubber.

04/

Adjustable Head Strap: Four-point harness with polypropylene crown plate for step-free tension tuning.

Use & Maintenance

Pre-Use Inspection: Examine silicone skirt, valve flaps, and head harness elasticity for cuts, dirt, or hardening prior to donning.

Seal Testing: Perform positive and negative seal checks by blocking air ports and inhaling/exhaling to check for air leakage around the face seal.

Cleaning Procedure: Detach all filter elements before cleaning. Hand-wash facepiece in warm water below $40^\circ\text{C}$ using mild detergent, then air-dry away from direct heat.

Storage Environment: Store in a clean, sealed container away from direct sunlight, high temperatures, and chemical fumes.

FAQ

Q: What standard test reports are available for European market distribution?

A: Test reports under EN 140:1998 and EN 136:1998 standards are available, along with Category III CE conformity documentation.

Q: What prevents the liquid silicone material from deteriorating under chemical exposure?

A: The liquid silicone structure is thermoset-molded to resist oil absorption, skin acids, and chemical vapor degradation, maintaining shape and seal flexibility over repeated cleaning cycles.

Q: Are private label logos and custom user manuals supported for volume orders?

A: Custom laser-engraved or molded logos, customized outer box printing, and multi-language instruction inserts are supplied according to project order specifications.

Q: How is quality controlled during factory volume production?

A: Production lines perform automated breathing resistance testing, sealing margin dimensional checks, and individual valve seating inspections on every manufactured batch.

Q: How long does the liquid silicone facepiece last under standard factory usage?

A: The silicone facepiece maintains structural integrity for 2 to 3 years with regular cleaning and proper storage, while filter cartridges are replaced based on usage hours and breathing resistance limits.
