Core performance: Uncompromising reliability indicators
- Working pressure: 6.5 - 12 bar
- Foam mixing ratio: 3% - 6% (Flexible to adapt to various fire extinguishing agents)
- Maximum reflux pressure: Up to 65% of the inlet pressure (ensuring system stability)
- Standard flow rate: At a pressure of 7 bar, it reaches 280 liters per minute (high efficiency, quick fire control)
- Applicable sizes: 65mm / 80mm (suitable for various pipeline layout requirements)
Why is it the preferred choice for industrial firefighting?

⚙️ Durable material, resilient to harsh environments
The main body is made of aluminum alloy and brass structure, resistant to corrosion and high pressure, and will not deform or leak even after long-term use.
It is equipped with a stainless steel filter, which effectively intercepts impurities and ensures the smoothness of the nozzle, making the system reliable and durable.

🔁 Flexible interface, compatible with global standards
Offer multiple inlet and outlet connector options, including common specifications such as Storz and BS, easily connecting to existing equipment and fire water pipelines, reducing renovation costs and making installation more convenient.

🎯 Precise release, enhancing fire extinguishing efficiency
A foam mixing ratio of 3% to 6% can be precisely adjusted for different fire situations. Whether it is an A-class solid fire source or a B-class liquid fire, it can achieve the best coverage and penetration effect.
🧰 Application Scenarios
Chemical plants, paint workshops, hazardous goods warehouses
Power station, oil pipeline, energy facility

Port logistics, transportation vehicle fire protection system
Any place equipped with dry powder/fog fire extinguishing systems

FAQ
Q1: The product introduction states that the foam proportion is 3% to 6%. How exactly is this adjusted? Does it require replacing any parts?
A: No need. This adjustment is very convenient and no components need to be replaced. The mixing ratio is adjusted as a whole through the foam ratio mixer on your system. The design of our release device itself ensures that within the broad range of 3% - 6%, a stable and uniform foam jet can be formed, with perfect atomization. You only need to set the ratio on the mixer according to the type of fire-extinguishing agent used and the fire situation. This head is fully compatible.
Q2: The maximum reflux pressure is 65% of the inlet pressure. What is the use of this parameter for me?
A: This is a crucial parameter that directly affects the stability and reliability of your entire system. In simple terms, this value represents how "resilient" our device is when it is "holding back" pressure. If the nozzle temporarily gets clogged or the valve malfunctions, it can withstand a backpressure as high as 65% of the inlet pressure without internal damage or leakage. This is akin to an internal safety buffer that effectively reduces the risk of the entire system crashing due to unexpected pressure surges, making your investment in firefighting more secure.
Q3: Between the 65mm and 80mm sizes, which one should I choose?
A: This mainly depends on the diameter of your existing fire protection pipes and the coverage area that you require with the flow rate.
- 65mm: More versatile, suitable for most standard workshops and storage areas, with relatively flexible pipeline layout.
- 80mm: This size is typically used in areas that require a greater flow rate and a larger coverage area, such as large factories or open areas of chemical plants.
Our suggestion is: Measure the diameter of your existing branch pipes directly, or let us know the size and type of the area you need to protect. We can then provide you with the most direct selection recommendation.
