Description

Technical Parameters

The Lightweight Single-Filter Respirator provides dependable respiratory protection using an 85-gram medical-grade TPE facepiece engineered to reduce facial pressure and worker fatigue during long operational shifts while maintaining standard bayonet cartridge compatibility.

Key Features

01/

85g Ultra-Light Body: Minimizes neck strain during prolonged wearing.

02/

Low Breathing Resistance: Integrated silicone exhalation valve accelerates heat and moisture dissipation.

03/

Ergonomic TPE Seal: Hypoallergenic thermoplastic elastomer conforms smoothly to various facial contours.

04/

Four-Point Head Harness: Adjustable elastic cradle balances weight distribution to prevent slippage.

05/

Standardized Cartridge Interface: Tool-free bayonet connection ensures fast and secure filter locking.

Design & Components

Component	Material	Function / Structural Detail
Face Seal	Liquid TPE	Soft inner lip profile creates an airtight seal with minimal clamping pressure.
Filter Dock	Reinforced Polypropylene	Single bayonet mount engineered for quick alignment and leak-tight twist locking.
Exhalation Valve	Silicone Leaf & ABS Housing	Downward exhalation airflow prevents fogging on protective eye visors.
Inhalation Valve	Silicone Membrane	Prevents backflow of exhaled moisture into the active filter media.
Head Harness	Polyester-Elastane Straps & PP Crown	Four-point tension adjustment distributes mask weight evenly across the head.

Use & Maintenance

Pre-Use Inspection

1.Inspect the facepiece body for tears, cracks, or deformation.
2.Verify that silicone inhalation and exhalation valves sit flat inside housings.
3.Check elastic head straps for loss of elasticity.

Donning & User Seal Check

1.Place the mask over mouth and nose, then position the crown strap over the head.
2.Hook lower straps behind the neck and pull harness ends for a snug fit.
3.Negative Pressure Seal Check: Cover cartridge inlet with palm, inhale gently, and hold breath for 5 seconds. The facepiece should collapse inward slightly.
4.Positive Pressure Seal Check: Cover exhalation valve outlet with palm and exhale gently. The facepiece should expand outward slightly without perimeter air leaks.

Cleaning & Storage

1.Remove cartridges and valves prior to washing.
2.Clean facepiece in warm water below 40°C with neutral detergent.
3.Air dry away from direct sunlight.
4.Store in an airtight container in a dry environment.

FAQ

Q: How does the weight of this respirator compare to dual-filter models?

A: At 85 grams, this single-filter facepiece reduces total weight by 30% to 40% compared to dual-cartridge models, lowering neck tension during extended work periods.

Q: Is the TPE material suitable for workers with sensitive skin?

A: The facepiece uses medical-grade Thermoplastic Elastomer that is latex-free and silicone-free, minimizing skin reactions during prolonged contact.

Q: Are custom color facepieces and brand logo printing available?

A: Custom pantone color matching for plastic frames and laser or pad printing for logos on valve covers are available under standard production terms.

Q: What is the recommended replacement schedule for the facepiece and valves?

A: The TPE body maintains functional integrity for 12 to 24 months under standard industrial cleaning routines. Silicone valves require monthly inspection and replacement if curling or stiffness appears.

Q: How is seal performance verified before shipment?

A: Production batches undergo breathing resistance evaluation, inward leakage testing, and valve seating checks in alignment with ISO 9001 protocols and EN 140 testing methods.
