3M™ V-Series Air Control Valves
Maintenance
Next, let’s look at the replacement parts for the continuous flow supplied air
respirator system. A complete assembly consists of the following components:
- An L-Series Headgear
- An L-122 Breathing Tube
- A high pressure air regulating valve or low pressure connector
with belt.
- A high pressure or low pressure supplied air hose with fittings.
The L-122 is the Breathing Tube. The entire breathing tube should be replaced
if it develops a leak, tear or becomes damaged.
The W-2963 is the Waist Belt. The entire belt should be replaced when it
becomes damaged.
There are 4 different air control valves approved for use with the L-Series
Headgear:
- 3M™ Vortex Cooling Assembly V-100
- 3M™ Vortemp™ Heating Assembly V-200
- 3M™ Air Regulating Valve Assembly V-300
Intended for high pressure applications, ranging from 25 to 90 psi.
- 3M™ Low Pressure Connector Assembly V-400
Intended for low pressure applications, ranging from 6 to 15 psi.
These air regulating valves have no moving parts except the control valve, so
there is little to wear out or maintain. If proper filtration of compressed air is
maintained, the muffler will stay clean and maintain its acoustic efficiency. The
following spare parts kits are available to overhaul and maintain the air regulating
valves.

This document outlines the maintenance procedures for 3M™ V-Series Air Control Valves, which are components of a continuous flow supplied air respirator system. The V-Series includes several models designed for different pressure applications and functionalities, such as cooling, heating, and general air regulation.

Function Description:

The 3M™ V-Series Air Control Valves are integral to a continuous flow supplied air respirator system, providing regulated airflow to the user's headgear. These valves ensure a consistent supply of breathable air, with some models offering additional functionalities like air cooling or heating to enhance user comfort in various environmental conditions. They connect the supplied air hose to the breathing tube and headgear, acting as the control point for the air delivery.

Important Technical Specifications:

  • Pressure Applications:
    • High pressure applications: 25 to 90 psi (for 3M™ Air Regulating Valve Assembly V-300).
    • Low pressure applications: 6 to 15 psi (for 3M™ Low Pressure Connector Assembly V-400).
  • Components of a complete respirator system:
    • L-Series Headgear
    • L-122 Breathing Tube
    • High pressure air regulating valve or low pressure connector with belt
    • High pressure or low pressure supplied air hose with fittings
  • Air Control Valve Models:
    • 3M™ Vortex Cooling Assembly V-100: Provides cooling functionality.
    • 3M™ Vortemp™ Heating Assembly V-200: Provides heating functionality.
    • 3M™ Air Regulating Valve Assembly V-300: For high pressure air regulation.
    • 3M™ Low Pressure Connector Assembly V-400: For low pressure air connection.

Usage Features:

The V-Series air control valves are designed for use with 3M L-Series Headgear, providing a continuous flow of supplied air. The system is modular, allowing for replacement of individual components like the breathing tube or waist belt if damaged. The different valve models cater to specific user needs, offering either temperature control (cooling or heating) or simple air regulation based on the pressure of the supplied air. The design emphasizes user comfort and safety by ensuring a steady and controlled air supply.

Maintenance Features:

The V-Series air control valves are designed with minimal moving parts, primarily the control valve itself, to reduce wear and maintenance needs. Proper filtration of compressed air is crucial to keep the muffler clean and maintain its acoustic efficiency. Spare parts kits are available for overhauling and maintaining the air regulating valves.
