Box Type Ventilation Unit
OBAIR BF series ventilators are high-quality products developed by our company, incorporating advanced technologies from Europe, America, and Japan. These ventilators come in 12 specifications, 9 structural forms, and various motor configurations, including direct drive and belt drive, with options for built-in or externally mounted motors. The direct drive type offers three adjustable airflow levels (high, medium, and low). The BF series provides an airflow range of 900m³/h to 25,600m³/h and a static pressure range of 100Pa to 800Pa. They can also be customized to meet specific customer requirements.
Model: BF
Air volume: 900m:/h~25600m'/h
Static pressure: 100Pa~800Pa

Technical Parameter
Reinforced Enclosure
The box structure has high strength. It can be made with double-sided spray-coated steel plate panels for both the inner and outer surfaces, or with double-layer metal panels with internal polyurethane foam panels, which is aesthetically pleasing.
High Airflow Impeller
Galvanized material impeller, delicate airflow, and high air volume for longer distance transmission.
Copper Core Motor
Copper wire motor, with copper core windings, offers good heat dissipation, abundant power, stable operation, and enhances motor efficiency.
Volute Casing
Streamlined design ensures stable airflow. The double-inlet structure with a streamlined shape is characterized by uniform and stable wind speeds.
Noise Reduction Measures
The fan outlet is connected to the casing with a highly elastic canvas soft connection, which reduces the noise generated during the operation of the unit.
High-Strength Steel Casing Base
The high-strength steel casing base comes standard with a lifting eye assembly suitable for both floor and ceiling mounting. If necessary, the lifting eyes can be removed for floor mounting.
Product Features
The "Haojin Oubo" brand BF series ventilators feature a front - bent multi - blade double - inlet centrifugal impeller, which has been dynamically balanced for high efficiency. They are equipped with spherical bearings to ensure smooth mechanical operation and low noise levels. The housing structure is robust, with both interior and exterior surfaces coated with plastic spray, resulting in an aesthetically pleasing appearance, as well as corrosion resistance and excellent rust prevention.
Product Features
The "Haojin Oubo" brand BF series ventilators are characterized by their high airflow, high static pressure, low noise, stable mechanical operation, high fan efficiency, attractive design, solid structure, and easy installation. They are widely used in air purification and HVAC ventilation systems for commercial buildings, hotels, basements, workshops, and factory buildings.
