Blue and white primary filter cotton is a high-efficiency pre-filter material designed for industrial ventilation systems. It is mainly used in the following three scenarios:
1.Pre-filtration of air supply system
As the first line of defense for air treatment, it can effectively intercept coarse particles, dust and flocs above 5μm, protect the rear-end precision filter, and extend the service life of the equipment. Typical applications:
• Primary filter section of clean workshop
• Fresh air system of commercial central air conditioner
• Ventilation system of industrial workshop
2. Air conditioning unit matching
Especially suitable for primary filtration of combined air conditioning units, fan coils and other equipment:
✓ Effectively filter atmospheric dust and pollen
✓ Protect core components such as surface coolers and heat exchangers
✓ Washable and reusable to reduce operating costs
3. Painting and baking equipment
Play a key role in spraying workshops and baking production lines:
• Intercept paint mist particles
• Filter organic volatiles
• Protect the combustion system
• Ensure the cleanliness of air supply
