DiversiTech Smokeys Smoke Emitter with 75 Second Burn Time, 600 Cubic Feet (Pack of 10)
DiversiTech Smokeys smoke emitters deliver dense, visible smoke for 75 seconds to test HVAC systems, detect leaks, and verify airflow patterns in spaces up to 600 cubic feet. These cartridges produce clean, non-toxic, oil-free smoke through a chemical reaction, making them safe for residential and light commercial diagnostic work. The 10-pack format keeps enough units on hand for multiple service calls without restocking trips. HVAC technicians, building inspectors, and facility managers use Smokeys to quickly identify leaks in heat exchangers, air ducts, tanks, and boilers, and to visually balance air distribution in ventilation systems.
Key Features & Benefits
Compatibility & Requirements
DiversiTech Smokeys work in any enclosed or semi-enclosed space where airflow or leak detection is required. The cartridges ignite with a standard lighter or match and require no power, batteries, or external smoke generator equipment. Use them in residential furnace cabinets, heat pump air handlers, commercial boiler rooms, ventilation ducts, range hoods, and fire alarm testing scenarios. Each emitter is a single-use cartridge designed for spaces up to 600 cubic feet.
What's Included
Frequently Asked Questions
Q: How do you use DiversiTech Smokeys smoke emitters?
A: Light the tip of a Smokeys cartridge with a standard lighter or match, then place it in the area you want to test. The cartridge will emit dense, visible smoke for 75 seconds. Position the emitter near duct openings, inside furnace cabinets, or at suspected leak points, and observe where the smoke travels to identify airflow patterns or breaches.
Q: Are Smokeys smoke emitters safe to use indoors?
A: Yes. Smokeys produce clean, non-toxic, oil-free smoke through a chemical reaction. The smoke is safe for indoor use in residential and commercial HVAC systems and leaves no oily residue on equipment or surfaces. Always follow basic safety practices and ensure adequate working space.
Q: What size area can one Smokeys smoke emitter cover?
A: One DiversiTech Smokeys cartridge covers up to 600 cubic feet of enclosed or semi-enclosed space. This makes a single emitter suitable for testing residential furnace cabinets, small commercial air handlers, or isolated duct sections in a single burn cycle.
Q: How long does each smoke emitter cartridge burn?
A: Each cartridge burns for 75 seconds. This duration provides enough time to trace airflow through ductwork, locate leaks in heat exchangers, or observe smoke behavior at supply registers and return grilles without needing to relight or deploy a second unit mid-test.
Q: Can you use Smokeys to test smoke detectors?
A: Yes. Smokeys are effective for testing the placement and sensitivity of smoke alarms and detectors. The controlled, repeatable smoke cloud allows you to verify detector response during code-compliance checks, fire drills, and commissioning of new fire alarm installations.
Q: What applications are Smokeys smoke emitters designed for?
A: Smokeys are designed for leak testing of heat exchangers, air ducts, tanks, and boilers, visual air balancing of HVAC systems, fire drills, and smoke alarm testing. HVAC technicians use them to detect cracks in furnace heat exchangers, confirm proper airflow distribution in ventilation systems, and identify duct leaks before they reduce system efficiency.
Q: Do Smokeys smoke emitters require any external equipment to operate?
A: No. Each cartridge is a self-contained unit that ignites with a lighter or match. Smokeys require no power supply, batteries, smoke generator machine, or additional accessories. Light the tip, place the cartridge, and the chemical reaction produces smoke for the full 75-second burn time.
Q: How many emitters come in one pack?
A: The DiversiTech Smokeys pack (SKU 14175) includes 10 individual smoke emitter cartridges. This quantity is convenient for service vans and allows multiple tests across several job sites or diagnostic scenarios without restocking.
Q: Can Smokeys detect small leaks in heat exchangers?
A: Yes. The dense smoke penetrates even small cracks and gaps in heat exchanger casings, making hidden breaches visible. Technicians use Smokeys to identify dangerous carbon monoxide leaks in furnace heat exchangers before they become safety hazards or code violations.
Q: Are there any cleanup requirements after using Smokeys?
A: No. Because Smokeys produce oil-free smoke, there is no sticky residue left on ductwork, equipment surfaces, or furnace components after use. The smoke dissipates naturally, eliminating post-test cleanup and protecting sensitive HVAC parts from contamination.
