In-Line Foam Proportioner

The in-line foam proportioner is a precision-engineered, portable mixing device designed to seamlessly blend foam concentrate with water at a calibrated ratio, forming a high-performance fire-fighting foam solution for rapid hazard containment. Crafted entirely from lightweight, corrosion-resistant aluminum alloy, it balances robust structural integrity with exceptional portability, making it an ideal choice for both mobile firefighting units and fixed fire protection systems across industrial, commercial and municipal settings.
At its core, the proportioner leverages the Venturi effect to draw foam concentrate from an external storage container through a flexible metal suction hose, automatically mixing it with the passing water stream at a pre-set ratio (typically 3% or 6%, customizable per project requirements). This passive operation eliminates the need for external power sources or complex control systems, ensuring reliable performance even in remote or power-deprived emergency scenarios. The unit features a precision-adjustable control knob, allowing operators to fine-tune the foam concentrate flow rate to match specific fuel types and fire intensities, optimizing suppression efficiency while minimizing foam waste.

Equipped with a range of interchangeable hose couplings-including BS, Storz and GOST thread types-it ensures universal compatibility with fire hose systems worldwide, enabling seamless integration into regional fire protection infrastructure. The aluminum alloy body undergoes a high-temperature anodizing treatment, enhancing its resistance to mechanical impact, chemical corrosion and thermal stress, while the reinforced mounting brackets allow secure installation on fire trucks, portable skids or fixed pipeline networks. The flexible metal suction hose provides unrestricted access to foam storage containers, with a long reach that accommodates varied storage configurations without compromising mixing stability.
Designed for rapid deployment, the proportioner can be connected to a water supply line in under a minute, with clear visual indicators for flow direction and concentrate level to simplify operation for both trained firefighters and emergency response personnel. It supports a wide operating pressure range (0.5–1.2 MPa) and flow rates (200–1000 L/min), delivering consistent foam solution output across variable water supply conditions. Compliant with international standards such as EN 1568 and UL 162, each unit undergoes rigorous hydrostatic testing and flow calibration before shipment, guaranteeing reliable performance in life-critical fire suppression operations.

Application scenario

Widely deployed in oil depots, chemical plants, refineries, municipal fire stations and marine vessels, this proportioner excels in scenarios requiring immediate, high-volume foam delivery. Its compact, lightweight design ensures easy transport to remote fire sites, while its durable aluminum construction ensures years of maintenance-free service, making it a trusted component of modern fire protection systems.

Frequently Asked Questions

What foam concentrate ratios are supported by this proportioner?Our standard models are calibrated for 3% and 6% mixing ratios, the most common for AFFF and AR-AFFF foam concentrates. Custom ratio variants (1% or 8%) are available for specialized industrial applications upon request.

Which hose coupling types are available, and can they be interchanged?The proportioner comes with interchangeable BS, Storz and GOST couplings, compatible with regional fire hose standards across Europe, Asia and the Commonwealth. Couplings can be quickly swapped in the field using basic tools, eliminating the need for full unit replacement.

What is the operating pressure and flow rate range?It operates efficiently within a pressure range of 0.5–1.2 MPa (5–12 bar) and supports water flow rates from 200 to 1000 L/min, ensuring stable foam mixing across low-pressure municipal supplies and high-capacity industrial pump systems.

Is the proportioner compatible with all types of foam concentrates?It is optimized for use with synthetic foam concentrates (AFFF, AR-AFFF) and protein-based foams. It is not recommended for use with high-expansion foams or corrosive chemical concentrates, which may damage the internal seals and flow path.

How do I maintain the proportioner for long-term reliability?After each use, flush the unit with clean water to remove foam residue, then dry thoroughly. Inspect the control knob, seals and suction hose monthly for wear or blockages, replacing damaged components as needed. Annual flow calibration is recommended to ensure accurate mixing ratios.

Can this proportioner be used in cold climates?The aluminum alloy body and metal suction hose are resistant to low temperatures, but trapped water may freeze in sub-zero conditions. After use, drain all fluid from the unit and store it in a heated enclosure to prevent ice formation and component damage.
