Foam Proportioner

SF Fire & Ventilation Systems provides foam proportioner solutions used in foam fire suppression systems to ensure accurate mixing of water and foam concentrate. These devices are critical components that directly affect system performance and extinguishing efficiency.

Foam proportioners are available in three main types depending on application requirements and system capacity:

1. In-Line Foam Proportioner

Designed for pipe sizes ranging from 2 1/2” to 8”, this type ensures a fixed proportioning ratio of foam concentrate and water directly into the system line.
Approval: Suitable for AFFF and AR-AFFF foam types – UL Listed, FM Approved

2. Wide Range Foam Proportioner

Capable of handling flow rates from 25 to 3500 GPM, this type offers flexible operation across varying system demands. It is ideal for large-scale industrial fire protection applications.
Approval: Suitable for AFFF and AR-AFFF foam types – UL Listed, FM Approved

3. Mixer (Venturi Type) Foam Proportioner

Used in 2 1/2” to 8” pipelines, this venturi-based system ensures precise foam-to-water mixing and stable foam quality under varying flow conditions.
Approval: Suitable for AFFF and AR-AFFF foam types – UL Listed, FM Approved

SF Fire & Ventilation Systems delivers foam proportioning solutions with a focus on accurate mixing performance, system reliability, and full compliance with international fire protection standards.
