3M Versaflo V-200 High Pressure Heated Supplied Air Valve Assembly

3M V-200 air heating regulator valve for supplied air systems.

The V-200 Heating Valve Assembly is an air-flow regulator designed to improve worker comfort in cold environments. By allowing the temperature of the supplied air to be significantly increased, this valve reduces thermal stress and fatigue while ensuring constant respiratory protection through a clean air supply from a compressor.

Benefits of the V-200 Heating Valve: Warmth and Control

This system is particularly effective for prolonged work in winter or refrigerated environments:

• Thermal Regulation: Capable of heating incoming air by up to 28°C (50°F) more than the ambient air temperature.

• Adjustable Flow: Allows the user to adjust the air volume according to their comfort needs while maintaining required protection levels.

• Ergonomic Design: Easily attaches to the belt and remains compact to avoid hindering movement during work.

• Integrated Safety: Equipped with an audible warning whistle that alerts the user if the air pressure drops below the safe threshold.

• Versatility: Compatible with a wide range of headtops, hoods, and face shields from the 3M(TM) M-Series and S-Series.

Technical Specifications

• Product Type: Air heating regulation valve (SAR).

• Heating Capacity: Increases air temperature by 28°C (50°F) relative to the inlet.

• Operating Pressure: Requires a clean compressed air source (Grade D).

• Product Series: Versaflo(TM) supplied air systems.

• Certification: NIOSH approved system when used with approved 3M components.

• Product Code: V-200.

Application Guide: Safe Use

1. Air Source: Connect the valve to a supplied air hose linked to a breathable air filtration system of appropriate quality.

2. Adjustment: Secure the valve firmly to the provided belt.

3. Connection: Connect the breathing tube of your headtop (e.g., M-200 or S-400 Series) to the valve outlet.

4. Setting: Use the control knob to adjust the temperature and flow before entering the contaminated area.

5. Warning: If you hear the whistle, leave the hazard zone immediately, as this indicates insufficient air flow.

FAQ: Frequently Asked Questions about the V-200 Valve

Can this valve be used in the summer?

It is not recommended to use the heating mode in hot weather. For warm environments, the V-100 cooling valve is preferred.

What type of compressor is required?

The compressor must provide Grade D breathable air (free of carbon monoxide and excessive contaminants) at a constant pressure specified in the manufacturer's manual.

Does the valve require electricity?

No, the air heating is produced by a vortex tube principle using only the energy from the compressed air.

Occupational Health and Safety (OHS) Expert Advice

• Filter Maintenance: Ensure that the compressor filters and the filtration panel are changed regularly. Damp or oily air can damage the internal mechanism of the V-200 valve.

• Pre-shift Inspection: Always check the status of the alarm whistle before every shift by slightly kinking the supply hose to simulate a pressure drop.
