This item is not kept in stock. Please allow 16 days for delivery.

The 3M Versaflo V-300DA assembly prepares a supplied air arrangement with a back-mounted SA-2600 dual airline tube for approved tight-fitting facepieces only. The regulating valve comes with the belt and adapters included in this configuration for painting, powder coating or powder handling stations. It is an air delivery assembly to be completed with an approved tight-fitting facepiece and breathing air. Check the industrial interchange fitting and pressure conditions within the approved combination before work.

Features and function of the valve assembly

• V-300 regulating valve is included in the assembly.
• SA-2600 dual airline tube uses back mounting.
• TR-325 standard belt carries the assembly.
• V-399 adapter and V-199 muffler/adapter are included.
• Industrial interchange fitting serves the intended supplied air configuration.

Compatibility and system integration

The V-300DA contents combine V-300, TR-325, V-399, V-199 and SA-2600. The supplied SA-2600 tube is not for use with hoods or loose-fitting headgear. This remains distinct from a configuration using another fitting or tube. The facepiece and breathing air supply must belong to the complete approved combination; NIOSH approval is not assigned to the valve alone.

Applications in painting and spraying

In a paint booth, powder coating area or spray station, this assembly prepares the worker's respiratory air delivery. Powder handling is also a recommended use. Workstation dusts, mists, fumes, gases or vapours must be considered when selecting the complete system; the valve alone does not filter them.

Supplied air setup

Prepare an external breathing air supply, then identify the hoses and fitting for the SA-2600 assembly. Set pressure according to the instruction table for the selected length and combination. Adjust the belt, check connections and perform prescribed tests before entering the work area.

Valve assembly specific limitations

Do not use this system in atmospheres containing less than 19.5% oxygen, with unknown contaminant concentrations, or that are immediately dangerous to life or health (IDLH). A shop compressed air network is not automatically a breathing air supply. The valve alone does not treat air contaminants. Do not transfer pressures or lengths from another configuration. Supplied air is not a general authorization to enter a hazardous atmosphere without selecting the appropriate system.

Care, inspection and replacement

Inspect hoses and fittings before connection, then check the belt and valve. Clean the valve exterior according to its instructions and replace worn or damaged parts. Test the assembly and air supply before return to service. Store the assembly dry at room temperature while preserving connections for the next use.

FAQ: the V-300DA dual airline valve assembly

Is the dual airline tube included?

Yes. The back-mounted SA-2600 is included in the V-300DA contents. It is for use only with tight-fitting facepieces approved for this combination.

Is a facepiece supplied?

No. Select it within the approved combination together with the breathing air supply.

Which adapters accompany the valve?

The V-399 adapter and V-199 muffler/adapter come with the V-300 valve and TR-325 belt.

How is supply pressure determined?

Use the instruction table for the hose, its length and the selected combination. Do not reuse a value from another assembly.

Does the valve make shop air breathable?

No. An external breathing air supply is required before complete system checks.

Complementary suggestions

For a technician preparing the dual airline assembly after cold weather receiving, plan PVC coated Emerald CX winter gloves (GSCXTAPVC) for outdoor handling. Clear Privo glasses (YA12261) support tests outside the mask. The valved Moldex mask (R2300) is selected for a different respiratory task without layering it with the system. Yellow waterproof trousers (VP19) address weather conditions, while fluorescent yellow reflective straps (VV20) complete visibility during movement.

For replacements, the TR-325 belt (RVTR325) and V-399 adapter (RV399) match supplied components; request SA-2600 and V-199 by exact model. For another supplied air configuration, review separately the V-300SR Schrader (RV300SR) fitting assembly, V-300 regulating (RV300) assembly or V-100-HIK cooling (RV100HIK) kit. These are alternatives, each requiring its approved combination and air supply.
