High-Flow Respiratory Protection for Industrial Mining WorkProtective Equipment (PPE)

Controlled Protection for Shotcrete & Maintenance Environments

Respirator performance underground isn’t about brands — it’s about breathing resistance, seal reliability, filter selection, and sustained work in confined areas. OPC supplies Dentec Comfort-Air® respirators because they deliver larger intake flow, dependable sealing, and practical use in abrasive and chemical conditions found in:

• Shotcrete application

• Backfill & paste operations

• Underground maintenance & service bays

• Torch cutting & welding repairs

• Slurry equipment rebuilds

In restricted airflow environments, low-restriction respirators make a difference.
