Frequently Asked Questions

What is a Silent Mix Flow Inline Duct Fan and how is it different from a regular exhaust fan?

A mixed-flow inline duct fan installs inside the ductwork (between walls, in ceiling cavities, or along chimney pipes) rather than on a wall or ceiling surface. It combines axial and centrifugal fan technology to deliver high airflow at high static pressure — ideal for longer duct runs where regular wall-mounted exhaust fans lose efficiency.

Where can this fan be used?

It can be used for kitchen chimney booster ventilation, bathroom exhaust, server room cooling, hydroponic grow rooms, air circulation in long duct runs, fresh air intake systems, and general ventilation for homes, offices, and commercial spaces.

Can it be used as both exhaust and fresh air intake?

Yes. The fan supports bidirectional installation — it can be mounted for air exhaust (pushing stale air out) or fresh air supply (pulling fresh air in), simply by reversing the installation direction.

What is the mixed-flow impeller design?

The mixed-flow impeller combines the benefits of axial flow (high volume) and centrifugal (high pressure) designs. This results in significantly higher airflow and static pressure than a standard axial fan while maintaining ultra-low noise levels.

How noisy is this fan during operation?

The fan operates in a silent range of approximately 25 to 35 dB(A) depending on the size variant, making it suitable for installation in bedrooms, offices, living rooms, and other noise-sensitive areas.

Can it be installed at any angle?

Yes. It supports flexible mounting — horizontal, vertical, or at any angle along the ductwork — making it easy to install in tight ceiling cavities, wall chases, and rooftop duct runs.

Is it energy efficient?

Yes. The mixed-flow motor design delivers maximum airflow at minimum power consumption, making it significantly more energy-efficient than traditional centrifugal or axial duct fans of comparable airflow capacity.

What duct size is compatible with this fan?

Each variant is size-specific — the 4 inch (100mm) variant requires 100mm ductwork, the 6 inch (150mm) requires 150mm ductwork, the 8 inch (200mm) requires 200mm ductwork, and so on. Always match the fan size to your existing duct diameter.

Does it come with a speed controller?

Some variants come with a 2-speed option. A compatible external speed controller can also be used for variable speed control. Check the specific variant listing for included accessories.

What is the warranty on this product?

It comes with a 1-year manufacturer warranty from Ardnib (Bindra Industries India Pvt. Ltd.).
