Product Technical Overview

AWG S4 Foam Nozzle 400 LPM, Germany

The AWG S4 Foam Nozzle 400 LPM is professional firefighting equipment manufactured by AWG Fittings GmbH in Germany. Designed for heavy foam application, this branch pipe is intended for use with a compatible foam concentrate solution and suitable foam proportioning equipment. The standard S4 model has a nominal flow rate of 400 litres per minute at a reference pressure of 5 bar.

Foam branch pipes are essential components in firefighting systems where foam is required to cover suitable burning surfaces and help suppress fires involving certain flammable liquids and combustible materials. The AWG S4 draws air into the discharged water-and-foam solution to generate low-expansion foam, which is then directed towards the target area.

The AWG S4 is part of the manufacturer's heavy foam nozzle range. Manufacturer documentation identifies several inlet configurations, including Storz and threaded connections, depending on the supplied variant. Buyers should confirm the precise model and connection before ordering to ensure compatibility with existing firefighting hoses and foam proportioning equipment.

Important product clarification: Your original product name says “High Expansion.” The standard AWG S4 heavy foam nozzle is documented as a low-expansion foam nozzle. AWG also offers medium-foam equipment and combination models, so the correct model should be verified before publishing this listing under a high-expansion designation.

Applications of the AWG S4 Foam Nozzle

Industrial Fire Protection

Industrial facilities may require foam equipment as part of a dedicated fire protection system. The AWG S4 may be suitable where the system requires a 400 LPM low-expansion foam nozzle and the selected foam concentrate is appropriate for the identified fire risk.

Flammable-Liquid Fire Response

Suitable firefighting foam can help cover certain flammable-liquid surfaces and suppress the release of vapours. The foam concentrate and application method must match the particular fuel and hazard. Equipment selection should follow the facility's approved fire protection design.

Warehouses and Commercial Facilities

Some warehouses and commercial premises use foam application equipment to address specific fire hazards. The correct nozzle should be selected according to the fire risk assessment, available water supply, required flow and installed hose connections.

Fire and Rescue Services

Fire and rescue teams may use heavy foam branch pipes as part of compatible hose-line equipment. The nominal flow rate, operating pressure, connection and concentrate compatibility should be checked before the equipment is used in an emergency.

Industrial and Emergency Response Equipment

The AWG S4 can be considered for firefighting equipment inventories where its rated performance meets the requirements of the foam delivery system. It must be operated by trained personnel according to manufacturer instructions and relevant safety procedures.

How to Select the Right AWG Foam Nozzle

1. Identify the required foam expansion. Confirm whether the application requires low-expansion, medium-expansion or high-expansion foam. These are different equipment functions and are not interchangeable.

2. Confirm the flow rate. The standard S4 model is rated at 400 LPM at 5 bar. Check that the pump and water supply can support the required operating conditions.

3. Verify the inlet connection. Select the appropriate Storz, threaded or other compatible connection for the existing hose system.

4. Check the shut-off arrangement. Confirm whether the selected version includes the required shut-off valve and any additional accessories.

5. Match the foam concentrate. Use a concentrate approved for the application and compatible with the proportioning equipment and nozzle.

6. Request manufacturer documentation. Confirm the exact AWG product number, rated performance, connection type and technical specifications before placing an order.
