BullEx Smoke Generators create the most realistic fire training scenarios by generating the thickest, densest smoke to recreate the actual experiences a firefighter will face.  Whether you are conducting search and rescue training, ventilation operations or initial fire attack drills, BullEx Smoke Generators don’t stop until your training is done.

BullEx Smoke Generators use smart controls to continuously produce the best smoke possible for firefighter training. Built on steel chassis with all metal structural components, these smoke generators are built to handle the toughest training demands.  No matter how long or intense your session is, BullEx Smoke Generators don’t stop until your training is done.

Smoke Generator 4000
With built-in handles, steel chassis and rubberized feet, the Smoke Generator 4000 is portable enough to be easily moved, but tough enough to handle the demands of firefighter training. Smart controls and an integrated smoke liquid tank enable the SG4000 to produce smoke continuously for hours.

Smoke Generator 6000
The BullEx Smoke Generator 6000 is a heavy-duty, high-volume Smoke Generator designed for the most demanding training scenarios. Dual heaters and a specialized heat exchanger ensure efficient smoke production on a large-scale. With integrated handles and built-in wheels the SG6000 can easily be repositioned in between evolutions.

Built on a steel chassis with all metal structural components

Easily moved to various areas of any facility where training is being conducted

Dense smoke
Our specially-formulated BullEx Smoke Liquid efficiently produces dense, thick smoke with extended hang time. Only one fluid type is necessary to produce quality smoke, so there is no need to change fluid to vary the density.

No smoke residue
Consistent temperatures keep the smoke from becoming “wet” and producing a residue

Wireless operation
Control the output and duration of smoke from a distance away from the evacuation area or for use in an HVAC system with the optional wireless control



Ventilation Training
Continuous high-density smoke, equal in quantity to smoke produced by a structure fire, allows every member of your department hands-on practice with hydraulic, PPV, horizontal and vertical ventilation

Search & Rescue Training
Createa variety of smoke settings from low to zero visibility to find victims during search and rescue or thermal imaging drills. Incorporate a BullEx SmartDummy rescue manikin into the evolution and create a realistic sense of urgency as the SmartDummy calls out for help

Large Area Search Training
Saturate a training environment with high density smoke in the time it takes your firefighters to don their gear

Mask Confidence Training
Train firefighters in zero visibility conditions to test their awareness and confidence of the PPE gear

FAST/RIT Combat Training
Train firefighters to locate and retrieve downed firefighters in a realistic scenario involving smoke


There are two major factors that affect training smoke quality: temperature and particle size. The uniform temperature inside the heating core ensures that the smoke fluid is vaporized into pure smoke. Temperatures that are too high result in burnt particles and temperatures that are too low result in a “wet” smoke that leaves a residue.

Particle size is what determines the density and “hang time” of smoke. The more uniform the particle size, the longer the training smoke will last before dissipating.



Traditional Smoke Machines
All smoke machines create smoke by pumping smoke liquid through heaters. As heat energy is transferred from the heaters to the smoke liquid, the heaters inevitably cool down. Once below a certain temperature smoke can no longer be generated, which is why smoke machines not designed for fire training need time to reheat and recharge between discharges. To extend operating time, these smoke machines often start at a higher-than optimal temperature, resulting in burnt particles. As smoke is generated, the heater temperature falls through the optimal range to below optimal resulting in “wet” smoke that leaves a residue. The smoke liquid is then cut off to give the heaters time to recover.


BullEx Smoke Generators
BullEx Smoke Generators are different. Instead of a constant flow of smoke liquid and a wide range of heater temperatures, BullEx Smoke Generators control the amount of liquid delivered to the heaters to precisely balance the heat transfer, ensuring a constant temperature and a constant supply of high quality smoke. This balance is achieved through advanced sensors and controls utilized by BullEx Smoke Generators. This technology not only provides a continuous supply of smoke, but also ensures the highest quality smoke possible with minimal burnt or un-vaporized particles.

I wanted to provide you a few comments on the BullEx SG6000 Smoke Generator that we recently purchased. We have had the opportunity to use the generator several times and it has surpassed all expectations on performance and versatility. Unlike other units we looked at, the BullEx SG6000 produces a thick dense cloud throughout our four- story drill tower. One of the best features is its ability to constantly produce smoke without shutting off. The smoke it produces is realistic and provides superb training for our firefighters.

Our firefighters have praised the performance of the BullEx SG6000 and the conditions it produces. The BullEx SG6000 was well worth our investment and we are looking forward to a continued relationship with BullEx.


West Sacramento Fire Department John Heilmann, Division Chief

The City of West Sacramento Fire Department Training Division recently purchased the BullEx Smoke Generator 4000. Our fire department was amazed at the amount of smoke produced from the machine. Our department has incorporated the use of the generator into our regularly scheduled training program.

Training that has been enhanced by the use of the generator include; simulated high-rise operations, search and rescue evolutions, firefighter survival and rescue techniques, vent enter search scenarios, and big box/warehouse fire training. One BullEx 4000 generator was powerful enough to smoke up a 60,000 square foot concrete tilt up structure in a timely manner.

The smoke generator has made it possible to provide impromptu training utilizing smoky conditions at a moment’s notice. Our Department has utilized the generator extensively for the past eight months and has experienced no operating or maintenance problems.

As the Training Chief for the West Sacramento Fire Department I would recommend the BullEx Smoke Generator 4000 to enhance any training program.

WOW! I would like to start by saying the BullEx Smoke Generator 4000 is like no other smoke generator.  I was completely sold on this product after the first five minutes of use!

The quantity and quality of the smoke produced more than justified the cost of purchasing the unit.

My Department has used the traditional style smoke generator for years.  It seemed to work most of the time but it always took a long time to smoke a house and even longer to clean the unit.  The first time we used the BullEx Smoke Generator 4000, I arrived at the training house an hour early to be sure that we would be able to smoke the entire four bedroom house before the other firefighters arrived.  After five minutes of run time the entire first floor was full of smoke with zero visibility!  I then used the BullEx Smoke Generator’s time delayed function for the rest of the three hour training.  I set the unit to run for 20 seconds every minute.  This setting maintained zero visibility in the house for the entire training.  This also helped to conserve the amount of smoke liquid we used.

The bottom line is that this is the best smoke generator money can buy!  If you are looking to recreate a real fire situation and offer the best level of training to your department, the BullEx Smoke Generator is a must.  Not to mention there is no cleaning of this unit.  Let it cool down and put it away.  Thank you, BullEx, for this product.  It has enabled our department and all of our county’s fire departments to offer a more realistic training for our firefighters.

Since our initial purchase of the BullEx Smoke Generator 4000 last year, our training evolutions have become much more realistic with the dense, clean smoke produced by the smoke generator. Our Firefighters have mentioned the realism provided by entering smoke filled structures and even by being able to read a smoke plume during aircraft crash exercises with the smoke rising in a dense cloud while still providing ground cover concealing aircraft parts and pieces.

The BullEx Smoke Generator 4000 continues to produce high quality training smoke with no interruption in output. This is a great change to our previous models which required a reheating time and produced limited “wet smoke” which took away the realism of the training evolution and resulted in large clean up areas at the end of the training sessions due to slick surfaces from contact with the wet smoke. Now we are able to fill our 3-story burn tower in under 7 minutes with no clean up required as the smoke is dense, dry and continuous.

I brag about the Smoke Generator 4000 so much our firefighters have told me I have a crush on the machine! This is actually true, after 26 years in the fire service and 10 years working in the training division; this is the best smoke machine I have ever encountered. Our department looks forward to purchasing a second Smoke Generator 4000 this year and seeing our capabilities expand, especially during outdoor training evolutions.

I would like to thank you and your BullEx team for listening to fire fighters and making a smoke machine that increases realism and is very dependable and cost efficient to operate. I look forward to working with you and BullEx in the future.
