QDJ TheONE AF-5 AND ONLY SMOKE GENERATOR YOU'LL EVER NEED
Oil Based - CO₂ High Performance - Versatile Smoke Generator Machine
Features:
DUAL MODE: HAZE AND FOG: Seamless switching between haze and fog modes. 100% duty cycle.
APS™ (AUTOMATIC PURGING SYSTEM): This system purges the heating module after the first heating cycle and after every emission of haze/fog preventing residual build up and clogging.
TOTAL RUNNING TIME: QDJ theONE™, running at full intensity, will generate 308 hours of haze and 20 hours of fog from its 20 L (5.3 US gallons) fluid container. Gas bottle will need to be changed at 50 hours for haze and 15 hours for fog. This can be done during operation without interruption of fog or haze emission
INTEGRAL TOURING FAN: External dual-position, adjustable fan with dedicated control channel which travels in its own compartment within the touring cradle. Can be mounted above or below haze/fog output to adjust directional flow.
ARS™ (AUTOMATIC REFILL SYSTEM): Specially designed to give maximum, consecutive, non-stop hours of haze/fog without interruption, QDJ theONE automatically refills its internal fluid reservoir from our external 10 L (2.15 US gallons) container of Premium Oil Based Fluid. 
SELF CLEAN: Automatic self-clean operation, maintenance free
 
Additional Features:
Leak Tests / Air Flow Visualisation
Ideally suited to large building envelope tests - the smoke hangs for around 4 hours without evaporating or layering (unlike water based smoke) which enables you to fill huge areas effectively and efficiently for air tightness testing work. 
 
Ventilation / Air Handling System Tests
For impulse / PPV (positive pressure ventilation) / road tunnel / car park ventilation tests for ventilation systems, the only smoke that gives you the most superior results is from the Phantom. It remains dense and highly visible over long distances and test durations and does not evaporate due to high speed air movement. Smoke from the units can also be given thermal buoyancy - the only machine capable of this. The smoke is heated and rises, staying visible where water based smokes simply evaporate.
 
Wind Tunnels Visualisation / Air Flow Analysis
In LVA / PIV laser doppler anemometry the fog particles faithfully follow flow dynamics. The fog does not evaporate in fast moving air streams, ideal for open ended wind tunnels, large or small. For visual perspective in closed (recirculating) small wind tunnels (not PIV LVA) you can reprogram the machine to use type B water based fluid which disperses quickly. As the units do not utilise a fluid pump, an ultra-smooth smoke output at any output level is ensured e.g. for laminar flow.
 
Smoke Detector and Smoke Extrat FAN Tests
Unlike water-based smoke, oil-based smoke can be given thermal buoyancy to closely replicate hot rising smoke from a real fire. Ideal if your smoke detectors are very high up in the ceiling. The smoke from the Thermo-Resist models is persistent to 200C (392F).
 
Fire Training
Not only does the smoke from the Thermo-Resist versions resist temperatures up to 200C (making them ideal for hot fire training), but its fluid use is unparalelled by any other machine producing such a thick, dense, persistent smoke. It is also the safest smoke available due to the huge reduction in smoke fluid chemical required to achieve complete white-out. The smoke has a very dull smell and is much less irritating compared to high concentrations of water based fog.
