G2

These filters are commonly selected where system cleanliness and component protection are important, but fine particle control is not yet required.

G2 filters help reduce the accumulation of dust on fans, coils, and ductwork, supporting more stable system operation and longer maintenance intervals.

Typical Applications

G2 air filters are used in ventilation systems where protecting equipment and maintaining operational reliability are key considerations.

Common applications include:

• Air handling units (AHU)

• Mechanical rooms and plant areas

• Industrial ventilation systems

• Equipment intake air filtration

• Pre-filtration for higher-efficiency filters

In these environments, G2 filters help limit internal contamination and reduce wear on system components.

Performance Highlights

G2 filters balance basic filtration efficiency with low pressure drop, making them suitable for continuous HVAC operation.

Key performance characteristics include:

• Improved dust capture compared to G1

• Low initial pressure drop

• Stable airflow under continuous use

• Reduced dust buildup on HVAC components

• Cost-effective protection for ventilation systems

By limiting coarse dust entry, G2 filters contribute to more consistent system performance and reduced maintenance effort.

FAQ

What is the main difference between G2 and G1 air filters?

G2 filters provide better dust retention than G1 filters, offering improved protection for HVAC equipment while still maintaining low airflow resistance.

Are G2 filters suitable for use in air handling units?

Yes. G2 filters are commonly used in air handling units to protect internal components such as fans and coils from dust accumulation.

Can G2 filters be combined with higher-efficiency filters?

Yes. G2 filters are often used as pre-filters to protect downstream filters and extend their service life.

Are G2 filters intended for indoor air quality improvement?

G2 filters are primarily designed for equipment protection rather than fine particle removal. For improved indoor air quality, higher-efficiency filters are typically required.
