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

The 3M Versaflo V-300SR assembly prepares supplied respiratory air delivery with a Schrader fitting. The valve, belt and adapters are combined for the intended assembly while the tube and facepiece remain to be selected. At painting, powder coating or powder handling stations, this distinction helps prepare connections before setup. A breathing air supply and verification of the complete combination remain essential for operation.

Features and function of the Schrader valve

• V-300SR valve has a Schrader fitting for the corresponding assembly.
• TR-325 standard belt is included for carrying the assembly.
• V-399 adapter is included in the contents.
• V-199 muffler/adapter accompanies the valve.
• Select the tube and facepiece separately within the approved combination.

Compatibility and system integration

The V-300SR combines the Schrader fitting valve, TR-325, V-399 and V-199. The tube and facepiece are not part of these contents. Choose them with a breathing air supply approved for the exact combination. NIOSH concerns the complete approved system rather than the valve alone.

Applications at painting and powder coating stations

Shop painting and spraying, powder coating and powder handling are recommended applications. The Schrader assembly must match the selected installation. Address contaminants such as dusts, mists, fumes, gases or vapours through complete respiratory system and air supply selection without assigning filtration to the valve.

Setting up the Schrader assembly

Confirm the installation fitting and hoses before connecting the assembly. Prepare an external breathing air supply and use the instruction pressure table for the selected length and combination. Adjust the belt and check the complete assembly before entering the workstation.

Schrader 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). The valve does not make shop network air breathable. Do not assign hoses, pressures or lengths from another assembly by analogy. A supplied air configuration must be approved for the exposure; choosing it alone does not allow entry into every hazardous atmosphere.

Care, inspection and replacement

Examine the Schrader fitting, other connections, belt and valve exterior before assembly. Clean the exterior according to instructions and remove worn or damaged parts from service. After replacement, check the supply and connections through the prescribed tests for the combination. Store the assembly dry at room temperature with connections protected from contamination.

FAQ: the V-300SR Schrader valve assembly

Which fitting distinguishes the V-300SR?

The Schrader fitting distinguishes this configuration. Check that it matches the selected approved assembly.

Is a breathing tube included?

No. Order the tube and facepiece separately according to the approved combination.

Which parts accompany the valve?

The TR-325 belt, V-399 adapter and V-199 muffler/adapter are part of the assembly.

Is the fitting enough to choose pressure?

No. Pressure depends on the instruction table for the hoses, their length and the selected combination.

Can shop compressed air be used directly?

First confirm a breathing air supply. Available compressed air does not automatically meet that requirement.

Complementary suggestions

For a technician preparing the Schrader valve before an intervention and reaching the outdoor station, plan grey anti-fog Solus glasses (YAS1102) for phases outside the headgear. The 8247 mask (R8247) is reserved for a separate respiratory task under the program. A yellow women's mesh, 5-point tear-away, 6-pocket vest (V489) serves site movement, while yellow waterproof overalls (VP5629) address rainy conditions. The traffic barrel cone base (EPTBAB) equips existing traffic markers near the connection area.

For V-300SR care, the TR-325 belt (RVTR325) and V-399 adapter (RV399) are identified replacements; request the V-199 muffler by model. For another installation, review separately the V-300DA dual airline (RV300DA) assembly, V-300 regulating (RV300) assembly or V-100-HIK cooling (RV100HIK) air kit. These assemblies are not accessories to add to the Schrader valve; each requires its approved air supply and connections.
