  • Provides a comfortable respiratory seal around the neck/face interface, maintaining system integrity and preventing ingress of contaminants.
  • Lightweight, fabric-based collar (polyurethane-coated knitted polyamide) balances comfort and durability for industrial/occupational use.
  • Compatible with all approved M-Series helmets and outer shrouds — ensures modular flexibility across different configurations.
  • Essential component for a complete M-400 series headtop assembly — ensures respiratory protection performance per manufacturer’s design.

×
  • Sealing interface: The M-444 inner collar forms a soft but effective seal between headgear shroud and wearer’s neck/face, preventing dust, particles or contaminants from entering the breathing zone.
  • Integrated shroud compatibility: Designed to zip into any M-Series outer shroud — enabling reliable enclosure when assembling full respirator helmets.
  • Comfort-oriented construction: Made from polyurethane-coated knitted polyamide fabric that sits gently against the skin while maintaining structural integrity under extended wear.
  • System safety maintenance: By ensuring correct seal and fit, the inner collar maintains the respiratory protection performance of the overall helmet / PAPR / supplied-air system.
  • Modular replacement part: As a detachable component, it allows easy replacement when worn or damaged without needing to replace the full helmet assembly.
  • Manufacturing & General Industry: As part of helmet-mounted supplied-air or PAPR systems for maintenance, assembly, painting, sanding, or dust-generating operations.
  • Metalworking & Fabrication: Use in welding, grinding, cutting, or foundry work where full-face/respirator helmets are required.
  • Construction & Infrastructure Maintenance: For workers needing head, eye and respiratory protection in environments with dust, particulate or airborne hazards.
  • Chemical / Petrochemical / Industrial Plant Operations: Where supplied-air or PAPR helmet systems are used to protect against fumes, vapours and particulates.
  • Utilities & Maintenance Services: For maintenance, cleaning, inspection, confined-space entry in utility, infrastructure or heavy-industry settings requiring full head-protection and respirator coverage.
Supplied as 1 inner collar (1 EA / case) under standard 3M packaging for M-Series inner shroud components.

FAQs

What is the purpose of the M-444 inner collar? ⌄

The inner collar provides a comfortable respiratory seal and is required to be zipped into the outer shroud for full M-Series helmet assemblies.

With which helmets or shrouds is M-444 compatible? ⌄

It is compatible with all 3M Versaflo M-Series outer shrouds and helmets (M-400 series).

What material is M-444 made of? ⌄

Polyurethane-coated knitted polyamide fabric — lightweight and designed for comfort and durability.

How is it packaged? ⌄

Supplied as 1 each per case (1 EA / Case).

Is M-444 enough by itself to provide respiratory protection? ⌄

No — M-444 is only the inner collar. Full respiratory protection requires the complete helmet assembly, including outer shroud, visor, air supply, and other required components.

Can the inner collar be replaced independently? ⌄

Yes — as a separate, replaceable component, it can be replaced when worn or damaged without needing to replace the entire helmet assembly.
