2.5 Inch Fire Jet and Spray Nozzle

The 2.5-inch DC spray nozzle is the "functional heart" of fire water guns/water cannons. Through optimized internal flow channels and an intelligent switching mechanism, it enables dual-mode output of "DC jet for targeted attack" and "spray for protective shielding".
Specifically designed to meet the dual needs of long-range precise strike on fire sources and close-quarters safe operation in fire suppression, its core value lies in three key characteristics: precise flow control, efficient atomization, and durability/reliability. It significantly improves on-site disposal efficiency and safeguards firefighter safety—serving as a critical component in the upgrade of modern fire-fighting equipment toward "specialization and refinement".
It is not merely a functional extension of fire water guns; through modular design and low-maintenance features, it also drives the development of fire-fighting equipment toward "specialization and intelligence"—an indispensable "small but critical" component in modern fire rescue.

Product Formation

The 2.5-inch DC spray nozzle is a core functional component of fire water guns/water cannons. Through its internal flow channel design and switching mechanism, it enables dual-mode output of "DC jet for targeted attack" and "spray for protective shielding," specifically developed to meet the dual needs of "long-range precise strike" and "close-quarters safety protection" in fire suppression. Its development revolves around three core objectives: precise flow control, efficient atomization, and durability/reliability. By optimizing material selection, structural design, and manufacturing processes, it has become a critical component in fire equipment that enhances firefighting efficiency.

It is not merely the "functional heart" of fire water guns—upgrading it elevates on-site disposal efficiency and safeguards firefighter safety. This nozzle represents the technical trend of fire nozzles evolving toward "precision, specialization, and durability".

Product Features

Dual-Mode Jet Output for Versatile Firefighting: Equipped with an internal flow channel design and switching mechanism, it delivers two distinct spray patterns: a high-kinetic DC jet for long-range precise attack (20–35m at 1.0MPa) and a composite spray for close-quarters protection (15–25m coverage), balancing firepower and safety.
Precise Flow Control & Efficient Atomization: The optimized internal flow channels and polished copper nozzle core (Ra≤0.6μm roughness) ensure stable flow output (error ≤5%) in DC mode, while the zirconia ceramic atomizing disc (0.15–0.25mm pores) generates uniform 50–150μm droplets (≥90% ≤100μm), enhancing cooling and gas dilution efficiency.
Durable Material & Corrosion Resistance: Crafted from 99.9% yellow brass (H62) with a chrome-nickel plating (≥8μm thickness), it resists salt spray corrosion (1000-hour salt spray test per GB/T 10125-2021) and high temperatures (surface ≤120℃ under 800℃ flame), extending service life to 8–10 years.
Quick-Switch & Low-Error Operation: A built-in rotating switch ring enables mode changes in ≤0.5 seconds, with anti-misoperation locking (error rate <1%) for reliable performance in high-stress fire scenes.
Adaptable to Harsh Environments: Compatible with 2.5-inch fire hoses/guns, it performs reliably in chemical plants (acid/alkali resistance), marine settings (salt spray), and high-temperature industrial zones (steel mills/refineries).
Low Maintenance & Modular Design: Key components (nozzle core, atomizing disc, filter screen) are replaceable individually. Maintenance cost is lower compared to non-modular nozzles.
