G3

Compared to lower-grade filters, G3 filters offer more consistent dust retention, helping ventilation systems operate more cleanly and predictably. They are commonly selected as a baseline filtration level where system stability and downstream protection are required.

G3 filters play an important role in maintaining cleaner internal airflow paths and reducing the load on higher-efficiency filters.

Typical Applications

G3 air filters are widely used in applications where ventilation systems require reliable pre-filtration without introducing excessive airflow resistance.

Common applications include:

• Commercial HVAC systems

• Industrial air handling units

• Make-up air units and supply air systems

• Pre-filtration before F-class filters

• Manufacturing and warehouse ventilation

In these environments, G3 filters help control general dust levels and support consistent system performance over time.

Performance Highlights

G3 filters are engineered to support stable airflow while providing dependable dust control under continuous operating conditions.

Key performance characteristics include:

• Reliable dust arrestance for general ventilation

• Balanced pressure drop suitable for HVAC systems

• Consistent airflow throughout service life

• Reduced contamination of ducts and equipment

• Improved protection for downstream filters

These characteristics make G3 filters a common choice for systems that require dependable pre-filtration as part of a multi-stage filtration strategy.

FAQ

What is the role of a G3 air filter in a ventilation system?

A G3 air filter is typically used as a general pre-filter. Its role is to capture coarse dust and airborne debris before air reaches more sensitive system components or higher-efficiency filters.

How does G3 differ from G2 filtration?

G3 filters provide more consistent dust capture than G2 filters and are better suited for long-term operation in commercial HVAC systems where overall system cleanliness is important.

Can G3 filters be used together with F-class filters?

Yes. G3 filters are commonly installed upstream of F-class filters to reduce dust loading and extend the service life of finer filtration stages.

Are G3 filters suitable for continuous operation?

Yes. G3 filters are designed for continuous ventilation operation and are widely used in systems that run for extended periods without frequent shutdowns.
