The 3M Versaflo Supplied Air Dual Airline Valve Assembly (V-300DA) is designed to help provide comfortable, continuous-flow respiratory protection when used as part of an approved 3M supplied-air respirator system.
Built for demanding industrial environments, this assembly helps deliver a steady supply of compressed, breathable air to compatible 3M Versaflo headgear and certain tight-fitting facepieces.
The V-300DA offers adjustable airflow control, helping workers tailor airflow for comfort during extended use, while its low-maintenance design reduces the need for filters, cartridges, or batteries.
