    Frequently Asked Questions
    What makes the DBF fan "low noise"?
    The fan uses a forward-tilted multi-blade centrifugal design and is housed in a sound-absorbing cabinet. For stricter requirements, muffler-type cabinets can be thickened or additional mufflers can be installed.
    Can this fan be used in explosive environments?
    Yes, we offer an explosion-proof version with a grade of EXdⅡBT4, specifically designed for locations with flammable and explosive gases.
    How many installation angles are available?
    The DBF fan is highly versatile, offering 12 different inlet air positions to accommodate various site-specific installation requirements.
    Does the fan support air purification?
    Yes, the fan can be configured with primary, secondary, or high-efficiency filters. When filters are added, the cabinet length is increased to account for the actual pressure loss.
    Where is the motor located in the DBF fan?
    The motor is installed inside the cabinet, which helps in compacting the design and further reducing noise during ventilation and air exchange operations.
    What are the primary applications for this fan?
    It is ideal for places needing quiet, high-volume airflows, such as hotels, cinemas, office buildings, basements, and mining enterprises.
