Smoke Machines for air flow testing for wind tunnels, laboratory tests, buildings:-

Oil Based Smoke Generator - oil-based smoke machines with continuous highly controllable output. The generated smoke can withstand high temperatures, has a very small particle size (no residue) and can easily be ducted. Can also be themally buoyant for smoke detector tests. Can also be re-programmed to use a faster dispersing water based smoke fluid if required. 240/110v.

Smoke Machines for general air flow visualisation / leak testing:-

	12v DC Smoke Machine - Highly portable battery powered machine for air flow tracing.
	Air Flow Checker - low output hand-portable unit. The ideal instrument for the testing and monitoring of small air currents and air movement. Even the slightest air movements become visible. Ideal for: ventilation or air conditioning systems, chimneys, smoke detectors, detecting leaks in industrial equipment, fume cupboards. Battery powered.
	Hand Portable Smoke Machine - The Rocket delivers long lasting smoke. Off-power facility on basic models. In use at pharmaceutical clean rooms around the world. The standard for spray booth clearance tests in the UK. 240/110v. Stainless steel version available.
	2.2kW High Output Smoke Generator - continuous high output 2.2kW machine for smoke logging large areas with the most persistent water-based smoke available anywhere. 240/110v.
	Oil Based Smoke Machine - oil-based smoke machines with continuous high output for large scale applications (see photo below). The generated smoke can withstand high temperatures. 240/110v.
