BAIHANGDA PRODUCT
G3 Primary Filter
G3 primary filter for HVAC pre-filtration and protection of medium-efficiency filter stages.
PRODUCT DETAILS
Product Overview
BAIHANGDA G3 Primary Filter is intended for routine HVAC and clean-air pre-filtration where the upstream stage must remove common dust and fibers before the air enters a finer filtration section. Compared with lower primary grades, it is selected for systems that need more stable pre-filtration performance while keeping maintenance straightforward.
Typical Applications
- Air-conditioning pre-filtration
- Cleanroom fresh-air units
- Industrial ventilation cabinets
- Pre-filter stage before F-series filters
Product Features
- Improved primary-stage dust holding
- Stable airflow for continuous ventilation
- Available in panel and media-pad constructions
- Designed to protect downstream medium filters
- Custom frame materials and dimensions
Selection & Customization
Provide the installation opening, air volume, frame requirement and replacement cycle target. BAIHANGDA can match the G3 construction to the air-handling equipment.
OEM / ODM: Dimensions, frame construction, installation form and project configuration can be customized according to confirmed requirements.
