Manufacturing and Developing Bushfire Sprinklers since 2014
BUSHFIRE ATTACK LEVEL - LOW
BAL-LOW means ember attack risk with minimal radiant heat.
Rating Overview
- Risk level: Insignificant heat exposure.
- Heat threshold: Not considered significant.
- Primary threat: Minor potential ember attack.
Impact on Building
- Material rules: Standard building materials are acceptable.
- Construction rules: No mandated bushfire upgrades required.
BAL Low Preparation Recommendations
BAL-Low homes face minimal radiant heat but remain vulnerable to wind-borne embers.
Embers can travel kilometres ahead of a front, making basic preparation essential even with no special building regulations.
1. Defend Against Ember Attacks
- Portable Ember Protection Sprinkler: A sprinkler system actively suppresses airborne embers, wets external surfaces, and raises local humidity to prevent ignition.
- Seal entry points: Block any gaps greater than 2mm around doors, windows, and eaves.
- Install tight mesh: Fit stainless steel or aluminium mesh over vents and weep holes.
- Keep gutters clean: Remove dry leaves, twigs, and bark regularly.
- Enclose the subfloor: Prevent wind from blowing embers underneath timber decks or floors.
2. Maintain the Property Envelope
- Mow lawns regularly: Keep grass short (under 100mm) and well-watered near the house.
- Prune low branches: Trim tree limbs within 2 metres of the ground to stop ground fires climbing.
- Clear the perimeter: Remove woodpiles, mulch, and flammable chemicals away from external walls.
- Choose plants wisely: Plant low-flammability vegetation with high moisture content near structures.
3. Establish an Emergency Plan
- Write a survival plan: Discuss and practice your household bushfire survival plan annually.
- Monitor fire apps: Download local emergency apps (like Hazards Near Me NSW) for real-time alerts.
- Pack an emergency kit: Keep a go-bag ready with woollen blankets, protective gear, and documents.
- Know your triggers: Decide early when you will leave, rather than waiting for a direct threat.
Uninterrupted Water Supply
A stand-alone water supply is essential for property bushfire defence, as mains town water frequently loses pressure or fails entirely during an emergency. We have engineered the Aussie Drencher to accommodate this by operating efficiently at ultra-low water pressures (just 100 kPa).
Three Stand-Alone Integration Options
- Option 1: Fuel-powered pump + SWS: Combines a dedicated petrol or diesel firefighting pump with a Static Water Supply (SWS) like a tank, pool, or dam. This setup delivers the high pressure needed for dual-purpose hose lines.
- Option 2: Powered electric pump + SWS: Pairs a standard electric water pump with a backup generator or a dedicated solar battery bank to ensure continuous operation when the power grid goes down.
- Option 3: Gravity-fed network + SWS: Connects elevated water tanks directly to the lines, using gravity alone to feed the system without relying on an external mechanical or electrical power source.
Why the Aussie Drencher Fits Every Setup
- High water efficiency: Consumes a low flow rate of just 4 litres per minute.
- Low pressure requirement: Fully activates and spins at a minimum threshold of 100 KPa.
- Extended runtime: Maximizes the lifespan of your static water reserves during a prolonged ember attack.
