Fogging devices are widely employed across various industries, including agriculture, healthcare, manufacturing and production, insect control, pollution management, and even entertainment!

It is also critical to recognise the role of fogging equipment in the COVID-19 pandemic scenario. The following page outlines the many types of fog machines and their primary applications.

How do fogging machines work?

The primary operation of a fogging machine is to turn fog juice (liquid) into vapour (or fog) by applying heat or pressure. Now, we may classify fogger devices depending on whether the conversion occurs by heat or pressure.

Types of fogging machines

Thermal and cold fogger machines are the two types of fogging machines. A Thermal fogging machine transforms fog juice into a thick fog by applying heat. Cold fogging machines, on the other hand, employ pressure to create vapour.

The heat generated by the thermal fogging devices is utilised to turn the fog juice into thick fog. Heat is produced by either the combustion of a fuel or the use of electricity.



Thermal foggers are commonly used for disinfection, insect management, and odour control. They have been critical in the eradication of Malaria, Dengue fever, and other mosquito-borne illnesses. Thermal fogging devices are still commonly utilised in mosquito control today.
