BLS® 4000 Series Reusable Half Mask

The BLS® 4000 Series Reusable Half Mask is easy to use and its quick disassembly times allow for cleaning and maintenance to be fast and easy. 

• 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.

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

• 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.

• BAYONET CONNECTION (b-lock)
  This connection is very intuitive, it allows a fast and safe fastening of the mask. It has a locking mechanism that allows the user to know if the filter has been placed correctly.
