Pleated G3 and G4 pre-air filters

Pleated G3 and G4 pre-air filters

Pleated G3 and G4 pre-air filters are commonly used in ventilation systems to filter out larger particles before the air reaches more sensitive filters, such as HEPA filters. These filters are designed to capture particles that are 5 microns or larger in size with varying efficiency levels.

Pleated G3 G4 Pre air filters are commonly used in ventilation systems to filter out larger particles and contaminants from the air before it enters the main filtration system. These filters are typically made of a pleated material that increases the surface area of the filter, allowing it to capture more particles as the air passes through.

The G3 and G4 ratings refer to the efficiency of the filter, with G4 being slightly more efficient than G3. These filters are often used in combination with higher-efficiency filters, such as HEPA filters, to ensure that the air entering the ventilation system is as clean as possible.

Temperature Resistance

Generally suitable for normal temperature ranges encountered in standard HVAC operations.

Washable: Some pleated filters can be washed and reused, depending on the manufacturer and material, but most are disposable.

End Caps

May have plastic or cardboard end caps for structural support inside the filter frame.

Airflow

Designed to minimize air resistance while trapping particles.

Certifications

May be UL classified for general use in certain environments.

When choosing between G3 and G4 filters, the decision often depends on the specific needs of the ventilation system, the environment in which it operates, and the desired level of pre-filtration before the air reaches more critical filters. Always refer to the manufacturer's specifications for detailed information about each filter's performance and compatibility with your system.
