What is 475LPM Selectable Flow Fire Nozzle?
The 475LPM Selectable Flow Fire Nozzle is a high-performance, multi‑flow firefighting tool engineered for professional use. It allows the operator to manually select from multiple flow rates (e.g., 115, 230, 360, and 475 L/min) to match the exact demands of the fire scene - from low‑flow overhaul to full‑power suppression. This flexibility saves water, reduces pump strain, and improves attack efficiency.
Built from hard anodized aluminum alloy with a rubber bumper and ergonomic pistol grip, the nozzle withstands harsh environments while providing recoil‑free operation. The 120° fog pattern offers crew protection, while the straight stream reaches up to 40 meters. A built‑in flush function clears debris without shutting down the line, making it a trusted choice for municipal, industrial, and offshore firefighting.

Types of FOREDE Fire Nozzles
Different nozzle technologies serve different fire attack strategies. Below are the main categories, with the 475LPM selectable flow nozzle leading in operational flexibility.
475LPM Selectable Flow Nozzle
475LPM Selectable Flow Fire Nozzle offers four discrete flow settings (115/230/360/475 L/min) at 7 bar working pressure. The operator rotates the flow selector to instantly adapt to the fire load – low flow for cleaning or overhaul, full 475 LPM for intense structural or wildland‑urban interface fires. The pattern ring provides a smooth transition from a compact straight stream (reach >40 m) to a wide fog (120°) for thermal protection.
Its lightweight anodized aluminum body (approx. 2.3 kg) and rubber bumper reduce fatigue. The stainless steel inlet filter prevents blockage, and the 360° swivel eliminates hose kinks. Ideal for departments that demand both water conservation and knockout power.
How to Choose a 475LPM Selectable Flow Fire Nozzle
Selecting the right selectable‑flow nozzle involves matching performance data to your department's tactics and water supply.
When evaluating a 475LPM selectable flow nozzle, consider the following: Flow increments – ideal steps are 115, 230, 360, and 475 LPM. Operating pressure – most are rated at 7 bar (100 psi); verify compatibility with your pump. Pattern control – a 120° fog is standard, but some offer 150° for enhanced crew protection. Material – hard anodized aluminum provides strength without excessive weight. Inlet compatibility – ensure the swivel matches your couplings (Storz, NH, BSP, etc.). Finally, look for a flush function and a rubber bumper to protect the nozzle during training and incidents.
Flow steps: 115‑230‑360‑475 LPM (or similar progression)
Pressure rating: 7 bar nominal, max 30 bar
Pattern: straight stream + full fog + optional off‑center positions
Construction: hard anodized Al alloy, stainless steel filter
Standards compliance: EN 15182, CE
Ergonomics: pistol grip, ball shut‑off, swivel inlet
Applications of 475LPM Selectable Flow Fire Nozzle
This nozzle type is the workhorse of modern firefighting, adaptable to almost any scenario where water or foam is used.
Municipal fire departments use the 475LPM selectable nozzle for interior attack (low flow) and defensive operations (high flow).
Industrial plants (refineries, chemical storage) value the ability to switch from a straight stream for distance to a wide fog for cooling adjacent equipment.
Airport ARFF vehicles often carry these nozzles as backup handlines.
Marine firefighting benefits from the corrosion‑resistant construction and the flush feature that clears saltwater debris.
Foam operations are simplified by attaching a foam tube to the same nozzle body.
By providing precise flow selection, the 475LPM nozzle reduces water consumption by 30‑50% compared to fixed‑flow or automatic nozzles during overhaul, while still delivering full flow when the fire is large. This dual nature makes it the most cost‑effective and environmentally responsible choice for today's fire services.
Fire Nozzle FAQ – 475LPM Selectable Flow Focus
Q1: What is the advantage of selectable flow over automatic flow?
A: Selectable flow gives the nozzle operator deliberate control over water usage. For example, you can choose 115 LPM for a small trash fire, then rotate to 475 LPM for a fully involved room – all without changing nozzles. Automatic nozzles vary flow based on pressure, which often results in higher water consumption when only partial flow is needed.
Q2: What pressure is required to achieve 475 LPM?
A: Typically 7 bar (100 psi) at the nozzle inlet. Ensure your pump can deliver that pressure while compensating for hose friction loss. Some models can operate down to 3.5 bar with reduced flow, but for the rated 475 LPM, 7 bar is standard.
Q3: Can I use foam through a 475LPM selectable flow nozzle?
A: Yes. Most manufacturers offer a foam‑aspirating attachment that clamps onto the nozzle tip. The selectable flow feature remains functional, allowing you to adjust foam solution flow without changing the nozzle. For best results, use a nozzle with a dedicated foam‑setting or a separate foam tube.
Q4: How do I maintain the flush function?
A: The flush position opens the nozzle fully without changing the pattern. Regularly operate the flush ring (usually a separate slide or rotation) to clear debris. After each use, flush with clean water, then dry and lubricate the shut‑off ball and seals according to the manufacturer's instructions.
Q5: Is the 475LPM nozzle too heavy for one‑person operation?
A: Modern selectable nozzles weigh between 1.8 and 2.5 kg. Combined with a pistol grip and recoil‑reducing design, one firefighter can comfortably handle the nozzle at full flow. However, always use proper hose management and backup personnel for large line operations.
Q6: Which standards should I look for?
A> Look for compliance with NFPA 1964 (US) or EN 15182 (Europe). These ensure the nozzle has been tested for flow accuracy, pattern symmetry, and durability. FOREDE nozzles are certified to both standards, guaranteeing reliable performance in emergency situations.
