Primary Efficiency Panel Air Filter

• G4 Filtration Class: Listed as G4 according to EN779 for primary air filtration.
• High Dust-Holding Capacity: Fluffy filter media captures coarse dust while supporting extended service intervals.
• Rigid V-Shaped Structure: Reinforced construction helps maintain filter shape during ventilation operation.
• Low-Stage Pre-Filtration: Designed to protect downstream higher-efficiency filters from premature dust loading.
• Large Filter Surface: Pleated media increases the effective filtration area within a compact panel format.
• Modular Installation: Suitable for multi-panel filter walls and centralized fresh-air filtration cabinets.
• Livestock Biosecurity Application: Supports reduction of coarse airborne particles entering high-biosecurity pig facilities.
• Easy Replacement: Panel configuration simplifies routine inspection and filter replacement.

• Pig-house positive-pressure air filtration systems
• Breeding pig and nucleus farm ventilation
• Boar station air filtration
• Sow and farrowing-house fresh-air systems
• Poultry-house air filtration
• Livestock centralized fresh-air systems
• Pre-filtration before F9 or other higher-efficiency filters
• New farm construction and ventilation retrofit projects

• Install the G4 filter upstream of the main high-efficiency filter.
• Ensure the filter panel fits tightly in the frame to prevent unfiltered air bypass.
• Install according to the specified airflow direction when directional markings are provided.
• Inspect filter surfaces regularly for dust accumulation, moisture and physical damage.
• Monitor filter resistance or differential pressure where the ventilation system includes pressure monitoring.
• Replace heavily loaded or damaged filters before airflow becomes excessively restricted.
• Keep the filter cabinet, intake screen and surrounding area clean.
• Do not operate the ventilation system with missing or improperly sealed filter panels.
• Filter replacement frequency should be determined by dust loading, operating hours and farm environmental conditions.

Q: What is the filtration class of this panel filter?
A: The listed filtration class is G4 according to EN779.

Q: What is the main purpose of a G4 pre-filter?
A: It captures coarse airborne dust and larger particles before the air reaches the higher-efficiency main filter.

Q: Why is a pre-filter important in pig-house air filtration?
A: It reduces dust loading on the main filter, helps maintain airflow and can extend the main filter service interval.

Q: Can it be used with an F9 filter?
A: Yes. G4 pre-filters are commonly installed upstream of F9 or other higher-efficiency filters in multi-stage livestock air filtration systems.

Q: Can the filter dimensions be customized?
A: Yes. Panel dimensions and frame configurations can be selected according to the filter cabinet and project requirements.

Q: When should the filter be replaced?
A: Replacement should be based on visible dust loading, pressure drop, operating time and the maintenance requirements of the filtration system.

Q: Is this the final filter in a high-biosecurity pig farm?
A: Normally no. It is primarily a pre-filter and is usually combined with a higher-efficiency main filtration stage.

Q: Can it be used for new and existing pig houses?
A: Yes. It can be incorporated into new-build filtration systems or compatible livestock-house ventilation retrofit projects.
