The Shilla Fire SL-69 Series is an elite lineup of specialized multi-purpose water mist and protective water curtain fire nozzles engineered and manufactured by Shilla Fire Co., Ltd. (Korea). The series features two key tactical models: SL-69D (Mist Water Nozzle) and SL-69F (Mist Water Curtain / High Fog Nozzle). Protected under international Design Registration No. 0369001, these specialized firefighting nozzles provide tactical solutions for challenging fire scenarios including wildland forest fires, sub-surface smoldering fires (peat/root layers), deep basements, and high-radiant-heat industrial environments.

The SL-69 Series delivers two specialized tactical operations:
1. Model SL-69D (Mist Water Nozzle for Forest & Sub-Surface Fires): Engineered for rapid initial fire attack in wildland terrain and subterranean smoldering conditions. The nozzle discharges a combined high-pressure water stream with embedded mist particles that penetrate deep into porous vegetative root layers to suppress concealed hot spots. An ergonomic ball valve control lever allows smooth single-handed transition between Shut-Off, Straight Stream, Mid Fog, and Mist patterns to conserve water while maximizing knockdown efficiency. It comes standard with interchangeable tips (High Fog Tip, High Flow Tip, and Low Flow Tip) for varied operational needs.
2. Model SL-69F (Mist Water Curtain / High Fog Nozzle): Engineered with precision micro-atomizing orifices that fracture the pressurized water stream into ultra-fine water mist droplets, creating a dense conical Water Curtain surrounding the firefighter. This microscopic mist barrier absorbs massive radiant heat energy, isolates ambient oxygen supply from the combustion zone, and mitigates toxic fumes. A 3-position ball valve (Straight - Shut-Off - Fog) allows firefighters to instantly alternate between attacking flames and maintaining protective thermal shields.

Both the SL-69D and SL-69F are machined from heavy-duty aerospace-grade aluminium alloy with a hard-anodized protective finish, delivering outstanding resistance against mechanical impact, abrasive grit, and chemical corrosion. Standard full-time swivel inlets (FE40 / NH 1-1/2" or 2-1/2") prevent hose twisting during intense maneuvering.
