It is designed for use with 3M 6000 Series reusable full face respirators, specifically models 6700, 6800 and 6900, according to 3M documentation. Compatibility with other models is not verified.

2. Does this part include inhalation valves?

3M installation instructions indicate that the 6894 nose cup assembly consists of the nose cup and inhalation valves. However, packaging contents may vary by region; always verify the contents of the specific product you receive.

3. Does the 6894 improve fogging of the visor?

The nose cup is designed to help purge exhaled breath and direct it away from the visor, which can help reduce lens fogging when the respirator is correctly fitted and used as intended.

7. Is the 3M 6894 suitable for all types of contaminants?

The nose cup itself does not determine the type of protection. The level and type of protection depend on the selected respirator model and the filters or cartridges used. Always choose filters according to the hazard assessment and relevant standards.
