G4 Primary Filter
G4 primary filter for higher-demand pre-filtration in cleanroom HVAC and industrial air systems.
PRODUCT DETAILS
Product Overview
BAIHANGDA G4 Primary Filter is a higher primary-stage filtration option for ventilation and cleanroom air systems that need stronger pre-filtration before F-series, HEPA or other downstream filters. It is frequently used to reduce the dust load entering later filtration stages and to support more stable system operation.
Typical Applications
- Cleanroom HVAC pre-filtration
- AHU and fresh-air units
- Pharmaceutical and electronics ventilation
- Pre-filter protection for medium and HEPA stages
Product Features
- Higher primary-stage dust capture within the G-series family
- Helps reduce loading on downstream filters
- Panel, pleated and project-specific constructions available
- Designed for routine replacement and maintenance
- OEM dimensions and frame options
Selection & Customization
Choose the G4 filter based on the existing AHU slot size, airflow, allowable depth, frame construction and maintenance frequency. Project drawings can be used for exact matching.
OEM / ODM: Dimensions, frame construction, installation form and project configuration can be customized according to confirmed requirements.
