The Concept Drain Master is a variant of the best selling Colt 4, it has a reinforced adapter capable of supporting heavy duty ducting.

The Drain Master makes identifying leaks in drain work dramatically easier & cleaner.  Potentially identifying leaks in minutes, that without the aid of high quality artificial smoke would take hours. Producing a persistent water-based non-toxic smoke.  The smoke can travel through hundreds of metres of drains. 

The unit runs off of the standard Colt 4 water based Aerosols which re-seal after use, so they can be used time and time again until exhausted. 

Concept can also provide accessories such as drain bags, drain bags with 1" bore through tube, drain stoppers, pressure testing kits & smoke aerosol packs. 

The Drain Master allows you to operate off power (once pre-heated).  Like the Colt 4, you can produce a large volume of smoke using the retained energy within the precision engineered heat exchanger.  This allows the user to carry the smoke generator around, making smoke as required, without a trailing electrical lead.  Once the unit has been pre-heated the Drain Master will generate high quality smoke for around 2 minutes (continuous max output).  When connected to the mains, the Drain Master will operate continuously at maximum output.
