What is the protection factor of a supplied air respirator/type C?

The protection factor of a supplied air respirator, also known as type C, is 1,000. This means that when properly fitted and used, the respirator can provide a level of protection that is 1,000 times greater than the concentration of the contaminant in the ambient air. This high level of protection is essential for workers in environments where they are exposed to harmful airborne substances, such as asbestos.

The significant protection factor associated with type C respirators makes them ideal for use in situations where there are serious health risks due to toxic substances. Unlike other types of respiratory protection, type C is designed to supply uncontaminated air, allowing for extended use in hazardous atmospheres, which is critical in industries where exposure limits are a major concern.
