The Air Purifier: Your Breath of Fresh Air
An air purifier is a smart device that continuously cleans the air in your room. It works by pulling in airborne pollutants—like dust, pollen, pet dander, smoke, and odors—and trapping them in advanced filters. The result is freshly purified air that's healthier to breathe, creating a cleaner, more comfortable living environment for you and your family.
What Is a Catalytic Oxidizer?
A Catalytic Oxidizer which also known as a Catalytic Incinerator or VOC Oxidizer there is an advanced air pollution control system designed to destroy volatile organic compounds (VOCs), hazardous air pollutants (HAPs), and industrial odors. Unlike thermal oxidizers that rely solely on high temperatures, a catalytic oxidizer uses a catalyst to promote oxidation at much lower temperatures (250–400°C). This significantly reduces fuel consumption and lowers operational costs.
As a trusted catalytic oxidizer manufacturer and leading Air Pollution Control System supplier in China, Senotay provides energy-efficient VOC abatement solutions for medium to high VOC concentration industries.

How Does a Catalytic Oxidizer Work? (Working Mechanism)
VOC-laden air enters the preheat chamber, where it is heated using a burner.
The preheated air passes through the catalyst bed, where oxidation occurs at lower temperatures.
Catalysts accelerate chemical reactions, converting VOCs into CO₂, H₂O, and harmless gases.
Heat from treated air is recovered through a heat exchanger, reducing the fuel demand.
Clean, treated air is discharged safely to the atmosphere.
This catalytic reaction achieves highly efficient oxidation without excessive energy consumption.
