Colt 4 Turbo Smoke Generator

A small, robust smoke generator whose physical size belies its power.

In its basic format, the Colt has the ability to produce a considerable amount of smoke 'off power' using the retained energy within the high mass heat exchanger, allowing an operator to carry a generator from room to room, making smoke as required, without a trailing electrical lead. After being on mains for around 15 - 20 minutes, the Colt will generate large amounts of smoke for around 2 minutes off-power.

Made in Britain

5 year parts warranty.
Lifetime guarantee on heat exchanger.

In service with numerous fire authorities world-wide, many NATO forces (including the USN for shipboard training), as well as analytical laboratories, asbestos removal specialists, and HVAC contractors, the Colt has an enviable reputation for simplicity of operation and reliability.

The Colt 4 Turbo is particularly suited to applications where extremely dense concentrations of smoke are required, or extremely large volumes need to be smoke logged. This is because of its very persistent nature. In this respect, the Colt 4 Turbo is one of the most powerful hand held smoke generators on the market today.

Available in 'basic' and 'remote' formats.

Colt 4 Turbo Smoke Fluid & Accessories
Refillable aerosol (supplied singly)
Fill with fluid (below) and pressurise to 100PSI / 7 bar with a hand pump, airline (e.g. in a garage forecourt) or inert gas supply. Can be used 25 times+ if used with care.
Overseas shipping costs are greatly reduced by ordering refillable aerosol(s) and containers of smoke fluid instead of pre-pressurised aerosols.
5 litres smoke fluid for use with refillable aerosol (above)
Will fill the refillable aerosol approx. 14 times.

Ducting adaptors attach to the front of the machine to allow secure connection of ducting hose to allow smoke to be positioned precisely, in hard to reach places or inside containers.

All our ducting hoses are now internally lined to be smooth thereby reducing frictional losses. When you duct smoke, you are restricting the smoke particles so deposition in the hose over time is inevitable. Using this machine and this type of hose, deposition is minimised.
