Brass Water Curtain Nozzle: High-Efficiency Open-Type Fire Protection Accessory
This brass water curtain nozzle is an open-type fire protection core component, crafted from premium brass with a wide 130-170° spray angle and multiple nominal diameter & thread size options. Featuring durable construction, customizable specs and non-hazardous material, it delivers powerful water mist/curtain effects for fire separation and suppression, ideal for fire fighting and emergency rescue in commercial, industrial and public space fire protection systems.
Engineered for professional fire safety and emergency response, this brass water curtain nozzle combines rugged brass build with a wide spray design to form an effective water barrier against fire spread. Its multi-spec customization and universal compatibility make it a versatile solution for creating fire separation zones and suppressing initial fires across diverse fire protection scenarios.
1. Premium Brass Construction & Long-Lasting Durability
Full brass material build with excellent corrosion, pressure and wear resistance, adapting to dry, humid and industrial harsh environments for long-term use.
Sturdy structural design withstands high water pressure and external impact during fire emergency use, no deformation or leakage for stable performance.
Non-hazardous material formulation, complying with fire protection and environmental safety norms, no harmful substance release in high-temperature fire conditions.
Polished brass surface treatment prevents rust and oxidation, extending the nozzle’s service life and maintaining reliable performance for long-term installation.
2. 130-170° Wide Spray Angle & Effective Fire Barrier
130-170° ultra-wide spray angle creates a continuous and dense water curtain/mist, effectively separating fire zones to stop flame and heat spread between spaces.
Optimized internal spray structure ensures uniform water distribution, maximizing the fire suppression and cooling effect of the water curtain.
Open-type design enables instant full-flow water spray once connected to the fire water supply system, responding quickly to emergency fire situations.
The water mist/curtain effect can also reduce smoke concentration, improving visibility for personnel evacuation and fire rescue operations.
3. Multi-Spec Design & Universal Compatibility
Nominal diameter options: DN15/DN20/DN25, customizable according to fire protection area size and water supply flow requirements.
Thread size choices: 1/2inch, 3/4inch, 1inch, matching standard fire protection pipe interfaces for seamless integration with existing fire water supply systems.
Lightweight and compact structure, suitable for wall, ceiling and pipe side installation, adapting to different building fire protection layout designs.
Precise thread processing ensures tight and leak-proof connections with pipes, preserving water pressure to maintain the spray effect of the water curtain.
4. Open-Type Operation & Quick Emergency Response
Open-type sprinkler design without temperature-sensing components, enabling immediate water spray when the fire water system is activated for rapid fire control.
No pre-activation condition required, ideal for fire protection scenarios that need instant fire separation and suppression, such as industrial workshops and commercial passageways.
Unobstructed internal flow channel ensures large water flow output, forming a thick water curtain in a short time to isolate fire sources effectively.
Simple operation that matches the fire protection system’s automatic or manual activation, no additional professional operation required.
5. Customizable Features & Practical Design
Support for spec customization, matching personalized fire protection needs according to different regional fire codes and project design requirements.
Optional custom packaging and name plates, facilitating centralized inventory management, maintenance tracking and on-site identification in large-scale building projects.
Smooth water inlet and outlet design reduces water flow resistance, ensuring maximum water utilization efficiency and stable spray performance under standard water pressure.
The nozzle’s spray direction is adjustable during installation, adapting to different fire protection area angles and layout needs for targeted fire separation.
6. Wide Applicability for Fire Fighting & Emergency Rescue
Industrial facilities: Factories, workshops, warehouses – creating fire separation zones between production areas and storage areas to prevent large-scale fire spread.
Commercial spaces: Malls, hotels, office buildings – installing at passageways, stairwells and elevator lobbies to form fire barriers for personnel evacuation.
Public places: Stations, airports, stadiums – dense water curtain for large-space fire suppression and smoke reduction, improving rescue efficiency.
Special fire protection areas: Petrochemical auxiliary areas, power distribution rooms – effective fire separation for high-risk fire areas with flammable and explosive materials.
Building fire protection systems: Matching with fire water pumps and pipelines, serving as a key component for fire separation and initial fire suppression in integrated fire safety solutions.
