BullEx Smoke Generators create the most realistic fire training scenarios by generating the thickest, densest smoke to recreate 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.



Consistent and continuous smoke generation
Produces constant flow of high quality training smoke with no recharging or reheating necessary

Durable and rugged
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

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 any 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
Create a 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.




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 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.

Apollo Career Center Doug Corwin, Public Safety Fire/EMS Coordinator

In January of 2014, Apollo Career Center took delivery of a BullEx SG4000. Before that, we had used 3 other smoke machines, but had issues with frequent clogging and diminishing smoke production. When the SG4000 arrived, we immediately took it to our training tower and set it up. After it had warmed up, we turned it on and within 5 minutes we had almost zero visibility. This was on a sunny day with the lights on. Within 20 minutes, we had most of our three story training tower filled with smoke.

We have used it consistently for the last year and a half and it has far exceeded our expectations. It has worked flawlessly without clogging or a decrease in performance.

I have highly recommended the SG4000 to other program directors and will continue to do so. Thanks for making such a great product.



Oakland Fire Department Gerald “Sarge” Stein, ARFF Training Instructor

I want to take this opportunity to express my gratitude to BullEx for producing such an excellent product!

This January, I was in the process of planning a 40 Hour Cal State Fire Control 5 ARFF Basics class. The class requires students to perform a live rescue drill inside our donated Federal Express Boeing 727 Training Aircraft. In the past we have borrowed a smoke generator from another agency because we did not have one of our own.

Last year, The Alameda Fire Department let us borrow their BullEx Smoke Generator for our drill. I was so impressed with the product that I decided to order one for our department.

After researching various other smoke generators, I found that BullEx’s had the best features, options and price available. I like the SG6000 Smoke Generator because of the simple control features and because it features wheels. This makes it easier for one person to move it around the training site.

When we conducted the drill this past week the SG6000 produced great volumes of non-toxic, cloudy smoke and blinding conditions. The fuselage filled with smoke so fast that we were able to perform back to back drills.

This June we are going to have our FAA mandated FAR Part 139 Tri-Annual Disaster Drill. There will be observers from various Fire Department organizations on hand while we perform a large scale Aircraft disaster drill with a hundred or so volunteer victims. Our new BullEx SG6000 will add to the realism of the drill and demonstrate the product’s capability to quickly create smoky conditions.

I want to thank BullEx for their professionalism and competency in meeting our needs. I look forward to working with BullEx for my Department’s training equipment in the future.
