Coarse

ISO Coarse filters are typically used as the first filtration stage in HVAC and industrial ventilation systems to protect downstream fine filters and reduce overall system contamination.

Typical Particle Size

• ≥10 µm

Key Features

• Efficient removal of coarse dust and fibers

• Low initial pressure drop

• High dust holding capacity

• Cost-effective pre-filtration solution

• Extends service life of downstream filters

Typical Applications

• Commercial HVAC air intake

• Industrial ventilation systems

• Manufacturing facilities

• First-stage filtration in multi-stage systems

Why Choose ISO Coarse Filters

ISO Coarse filters provide reliable protection against large airborne particles while minimizing energy consumption and maintenance frequency.

FAQ

What does ISO Coarse mean under ISO 16890?

It means the filter removes at least 50% of particles larger than 10 micrometers based on standardized testing.

Are ISO Coarse filters suitable as final filters?

No. They are designed for pre-filtration and should be combined with finer filters when higher air quality is required.

Do ISO Coarse filters replace G4 filters?

ISO Coarse broadly corresponds to former G-class filters, but the classification and test methods are different.
