3M V-400 low pressure supplied air valve assembly

A low pressure supplied air solution designed for 3M respiratory systems

The 3M(TM) Versaflo(TM) V-400 low pressure supplied air valve assembly is designed to provide continuous airflow to the user from a low pressure compressed air source. Belt-mounted, it fits into a supplied air respiratory setup and is intended for workplaces seeking a more compact, coherent and easier-to-organize breathable air configuration at the workstation.

A complete assembly to support a coherent respiratory setup

According to 3M documentation, the RV400 includes the V-400 valve, TR-325 belt, V-399 adapter and V-199 muffler. It is not a standalone facepiece; rather, it supports a low pressure supplied air setup in which each component must be selected according to actual system compatibility. Its design also allows the worker to adjust airflow to the most comfortable level, helping improve respiratory comfort during work and support productivity on repetitive or longer-duration tasks.

When this product becomes a strong choice

The RV400 can be relevant for tasks such as painting, powder coating, powder handling and spraying when respiratory protection requires a low pressure supplied air solution. It is NIOSH approved for type C and CE supplied air systems and should be used within that product logic. It should therefore not be confused with high pressure components or systems based on a different air supply architecture.
