3M HF-300 Series Half Mask Respirator Mask, Size M

This respirator mask is a medium-sized half facepiece intended to protect workers in industrial settings by providing a close-fitting barrier against airborne contaminants. It combines resilient elastomeric components and textile reinforcement to form a comfortable seal for routine tasks in electronics, electrical, mechanical and automation environments. The assembly meets recognised European and Australasian standards for respiratory protective devices.

• Ethylene propylene diene monomer body for chemical resilience and durability
• Thermoplastic elastomer facepiece for a flexible facial seal and comfort
• Polyester with neoprene core straps for secure positioning and reduced slippage
• Over-moulded polypropylene Interface for stable component integration
• Conforms to EN 140:1998 for half mask performance and construction
• Certified to AS/NZS 1716:2012 for use in regulated occupational settings

• Suitable for soldering and PCB assembly operations in electronics
• Ideal for routine maintenance on electrical panels and switchgear
• Used with bench assembly tasks in mechanical workshops
• Can be used in automated production lines with particulate or fume exposure

The main sealing component is MADE from an ethylene propylene diene monomer compound, chosen for its resistance to common workshop contaminants and long-term dimensional stability.

A thermoplastic elastomer facepiece is over-moulded onto a polypropylene interface, combining flexibility with a firm attachment point to preserve the seal during head movements.

The strap assembly uses polyester with a neoprene core, offering a balance of stretch, cushioning and reduced slippage for extended tasks.

It is manufactured to comply with EN 140:1998 and is certified under AS/NZS 1716:2012, indicating conformity to recognised half mask criteria.
