What flow rates and spray patterns does this nozzle support?
Our standard model offers adjustable flow rates from 200 L/min to 600 L/min, with three core spray modes: solid jet for long-range knockdown, wide fog for heat/smoke control, and fine mist for sensitive areas. Custom flow variants (150–800 L/min) are available for specialized industrial or marine applications.
Is the nozzle compatible with both freshwater and foam solutions?
Yes, it is fully compatible with freshwater and low-expansion foam concentrates (AFFF, AR-AFFF) at 3% or 6% dilution ratios. The internal flow path is designed to resist clogging from foam residues, ensuring consistent performance even after repeated foam use.
How do I maintain the nozzle to ensure long-term reliability?
After each use, flush the nozzle with clean water to remove debris or foam residue, then dry thoroughly. Inspect O-rings and seals monthly for wear or cracking, replacing them as needed. Annually, disassemble the flow selector mechanism and lubricate moving parts with food-grade silicone grease to preserve smooth operation.
Can this nozzle be used in cold climates without freezing?
The nozzle's smooth internal bore minimizes trapped water, reducing freeze risk. For sub-zero environments, we recommend draining the nozzle completely after use and storing it in a heated enclosure. An optional drain valve kit is available to further prevent ice formation.
What certifications does this nozzle hold?
All units comply with EN 1568 (Europe), and CCCF (China) standards, with full test reports and certification documentation available for regulatory review and project approval.
How does this nozzle differ from basic fixed-flow models?
Unlike fixed-flow nozzles, this selectable-flow variant allows on-the-fly adjustment of output and spray pattern, eliminating the need to carry multiple nozzles for different scenarios. This reduces equipment load for firefighters and enables faster adaptation to evolving fire conditions.
