Foggers and sprayers are often treated as interchangeable equipment, but they apply solutions in very different ways. Choosing the correct machine affects coverage, application control, productivity and safety.

What Is a ULV Cold Fogger?

ULV stands for Ultra-Low Volume. A ULV cold fogger uses high-speed airflow to break a compatible liquid into fine airborne droplets without heating the solution.

The fine mist can reach broad areas, uneven surfaces and locations that may be difficult to cover efficiently with a standard trigger or pump sprayer.

ULV cold foggers may be used to apply compatible products for:

• Disinfection and sanitation
• Odour-control treatments
• Restoration and remediation work
• Pest-management applications
• Commercial and industrial facilities

The solution must be approved for the intended application method.

ULV Fogger vs Standard Sprayer

A standard sprayer generally creates larger, wetter droplets and applies them directly to a targeted surface. It is useful when visible and concentrated surface coverage is required.

A ULV cold fogger produces a much finer mist, making it more suitable for controlled distribution across larger or more complex areas.

Cold Fogger vs Thermal Fogger

The most important difference is heat.

A cold fogger atomises a liquid without heating it. This makes it suitable for many water-based solutions that are specifically approved for ULV application.

A thermal fogger heats a compatible formulation to create a dense, highly visible fog. Thermal fogging involves additional heat, chemical-compatibility, fire and ventilation considerations and should only be performed by appropriately trained operators.

Never place a thermal-fogging solution into a ULV cold fogger unless both the chemical and equipment manufacturers specifically approve it.

A Fogger Does Not Replace Cleaning

Fogging should be part of a properly designed cleaning or treatment process. It does not remove dirt, organic matter or surface contamination.

Surfaces should normally be cleaned first. The approved treatment can then be applied according to its label, including the correct concentration, coverage, contact time and re-entry instructions.

The fogger distributes the solution—it does not make an unsuitable chemical effective or safe.

Why Choose a Cordless Fogger?

The XPOWER F16B is a rechargeable, cordless ULV cold fogger designed to give operators greater mobility without being restricted by a power lead.

A professional fogger should provide:

• Adjustable solution output
• Consistent atomisation
• Comfortable handling
• Sufficient battery operating time
• A secure chemical tank
• Replaceable batteries and service parts
• Local technical and after-sales support

Replacement batteries, chargers, motors, valves and other components are available for the XPOWER F16B through XPOWER Australia.

Safe Fogging Practices

Before fogging:

• Confirm that the solution label permits fogging or ULV application
• Follow the product label and Safety Data Sheet
• Wear the specified personal protective equipment
• Remove people, pets and uncovered food when required
• Observe the stated contact and re-entry times
• Provide ventilation as directed
• Never use flammable or incompatible liquids
• Clean the fogger after use according to its instructions

Choose the Application—not Just the Machine

A standard sprayer is better for direct surface treatment. A thermal fogger suits specialised treatments requiring heated fog. A ULV cold fogger provides controlled, fine-mist distribution without heating the solution.
