BLS 4000 Respiratory Half Face Mask

Easy and fast maintenance
It can be disassembled in less than a minute making cleaning and maintenance much easier.

New mask 25% lighter
The reduction in the thickness of the oronasal allowed a 25% reduction in the weight of the half mask, which appears to be among the lightest on the market.

Drop-off
New front mask with quick attachment/release system and sliding elastics, which allow you to remove and lower the half mask without removing the head harness.

Head harness
Thinner and lighter head harness, with a quick adjustment, allowing excellent compatibility with other PPE.
