Patented Bionic Venturi Mixing Structure, Stable On-Site Foam Molding
PQ Series Fire Foam Gun
Different from conventional simple hole air intake of ordinary foam guns, this upgraded PQ series adopts bionic arc venturi mixing cavity, which rebuilds internal water flow operating track without external power drive or matched proportional mixing equipment. Under fluctuating water supply pressure between 0.4MPa to 0.7MPa, the inner cavity automatically forms stable negative pressure difference to suck ambient air and foam concentrate synchronously.
Secondary swirling mixing technology is adopted inside the gun body to eliminate uneven foam, water separation and splashing defects of traditional products. It steadily generates uniform low-expansion fire suppression foam with expansion ratio above 5 times. The formed foam features high adhesion, vertical surface clinging performance and long oxygen isolation period, which can cover burning oil, chemical solvent surface rapidly to stop flame spread and prevent secondary re-ignition efficiently.
Split Dual-Mode Switching Design, One Tool for Full-Category Fire Response
Most mainstream handheld fire nozzles on the market only support single water spraying or fixed foam spraying function, which requires enterprises to purchase two sets of fire tools for differentiated fire disposal, increasing inventory cost and emergency preparation difficulty. This PQ foam gun realizes integrated manual mode switching without auxiliary disassembly parts.
Switch to pure water straight jet mode for rapid cooling and extinguishing Class A solid fires including timber, plastic, textile and warehouse combustible materials; switch to self-inducting foam mode to tackle Class B flammable liquid fires such as diesel, crude oil, industrial coating and corrosive chemical liquid. Integrated dual functional design simplifies on-site fire operation, shortens emergency response time, and lowers overall fire equipment procurement budget for terminal factories, ports and vessels.
Differentiated Flow Calibration, Scenario-Matched Model Layout
Aiming at the pain point that universal foam guns cannot adapt site fire scale differences, we set two professionally calibrated models with targeted hydraulic parameters to meet segmented global procurement demands, while keeping unified interface size and interchangeable spare parts:
✅ PQ4 Compact Version: Optimized narrow-diameter flow channel, steady small water output, maximum effective jet distance up to 26m. Built for closed small-space fire scenes, including indoor paint workshops, gas station operation areas, small logistics warehouses and container fire cabinets, flexible for narrow-site manual operation.
✅ PQ8 Heavy-Duty Version: Enlarged integrated flow passage, boosted foam supply volume, stable 24m long-range covering capacity. Developed for large-risk open scenarios, such as petrochemical tank farms, coastal bulk cargo docks, ship engine compartments and chemical raw material stockyards, coping with large-area liquid fire hazards efficiently.
Both models adopt unified DN65 standard quick coupling, compatible with global standard fire water pipes, realizing cross-model replacement and convenient spare parts management for fire teams.
Whole-Body T6 Tempered Anti-Corrosion Craft, Adapt Harsh Coastal & Chemical Working Conditions
Ordinary cast aluminum fire foam guns are easy to suffer from inner wall scaling, air inlet blockage and surface oxidation when exposed to seawater salt fog, chemical alkaline vapor and humid industrial air for a long time, leading to performance attenuation and frequent replacement. This product selects high-strength 6061 aviation aluminum alloy, processed by integral T6 heat treatment plus double-layer hard anodizing oxidation treatment.
The inner flow wall achieves mirror polishing treatment to avoid foam residue adhesion and pipeline clogging; external gun body forms dense anti-oxidation protective film to resist salt fog erosion, weak acid and alkali corrosion. Compared with ordinary models, its service life is improved by 45% in marine, petrochemical and coastal port environments. Meanwhile lightweight optimized structure reduces handheld load, lowering operator fatigue during long-time fire disposal.
Humanized Integrated Grip & Pressure Buffer Design, Safer Manual Operation
Combined with global firefighter operating habit data, the gun grip adopts non-slip curved ergonomic molding, equipped with embedded pressure buffer pad to offset instant water flow recoil during high-pressure spraying. It avoids hand slipping, arm strain and unstable shooting caused by high water pressure impact, realizing single-person stable handheld operation without fixed support bracket.
The reserved external foam liquid suction port is equipped with detachable filter screen to block impurity sediment in foam liquid, protecting inner mixing cavity from abrasion damage. All connecting threads adopt precision cutting technology for tight sealing, effectively preventing water leakage, pressure loss and foam leakage during high-pressure working status.
Zero-Complicated Maintenance Design, Lower Long-Term Site Management Cost
Breaking the traditional design with numerous disassembled vulnerable accessories, this foam gun adopts integrated seamless gun body structure, with no fragile sealing ring, easily damaged mixing core and wearable guide parts. After daily fire drill or emergency use, operators only need flush inner cavity with clean water and place it in ventilated environment for natural air drying, no regular oil maintenance or professional disassembly inspection required.
Standardized outer size fits universal fire cabinet embedded placement, convenient for unified site classification management and regular fire department acceptance check. Stock standard models support fast global delivery, customized logo, export neutral packing and third-party factory inspection report are available for EPC engineering, marine project and bulk industrial order demands.
