Duct Fan No name ARIL 310 ECO (model 01-317) — inline axial ventilation fan, compact size

The inline duct fan No name ARIL 310 ECO (model 01-317) is an axial ventilation unit designed for mounting inside round air ducts to support both exhaust and supply airflow. Its compact size makes it suitable for integration into residential and light-commercial ventilation channels where space is limited. The fan is intended for continuous or intermittent duct-mounted operation and works with standard round duct systems to improve air extraction in bathrooms, kitchens and similar indoor spaces.

Advantages

The fan’s axial design provides a straightforward airflow path with low resistance, enabling effective air movement in constrained ductwork. Its compact form factor simplifies installation in tight spaces and reduces the need for additional mounting or structural modification. The unit is compatible with common round duct diameters and can be installed inline without significant changes to existing systems. Noise and energy characteristics are optimized for typical domestic and small commercial environments, offering a balance between performance and efficiency.

Suitable for

• Bathroom and toilet exhaust ventilation
• Kitchen ventilation ducts where hood or general extraction is required
• Supplementing fresh air supply in small rooms or ventilation channels
• Inline installation in residential and light-commercial duct systems

Key specifications

• Axial impeller design for direct duct airflow
• Compact cylindrical housing suitable for round ducts
• Designed for duct-mounted operation in exhaust or supply mode
• Suitable for residential and light-commercial ventilation applications
• Compatibility with standard round ductwork and inline placement

How to use

Install the inline fan inside a round duct section following local electrical and building codes. Position the unit so airflow direction matches the intended exhaust or supply function. Secure the fan within the duct using appropriate clamps or mounting brackets and ensure all duct joints are sealed to prevent leaks. Connect the electrical supply per the manufacturer’s wiring diagram and, if required, integrate with a timer, humidity sensor or external switch for automated control. Verify proper operation by checking airflow and listening for abnormal noises during initial run-in.

Usage recommendations

For reliable performance, select a duct length and diameter that minimize sharp bends and excessive friction. Periodically inspect the fan and duct for dust buildup and clean as needed. When using the unit in humid areas such as bathrooms, ensure electrical connections and mounting hardware are rated for damp environments. To maintain efficiency, avoid restricting inlet or outlet openings and follow any specific maintenance intervals advised by the fan manufacturer.
