Inline duct fan airRoxy aRil 100 — axial ventilation for 100 mm duct

The airRoxy aRil 100 is an inline duct fan engineered for installation in 100 mm circular ventilation ducts. Designed for axial airflow, this compact unit is suitable for use as either an exhaust or supply fan in residential and small commercial applications. The fan is intended for in-duct mounting and connects directly to standard round ducts, providing ventilation for bathrooms, kitchens, utility spaces and short localized ventilation runs. It supports both intermittent and continuous operation depending on system wiring and installation choices.

Advantages

The fan delivers directed axial airflow in a compact housing that minimizes space requirements within ductwork. Its design allows simple inline installation into 100 mm ducts without the need for complex adapters. The unit operates quietly for its size and is suitable for continuous or intermittent use when wired appropriately. Built for typical domestic ventilation tasks, it provides a practical balance of airflow performance and ease of installation.

Suitable for

• Bathroom extraction in single-room or small multi-room installations
• Kitchen ventilation for localized exhaust points
• Ventilation of small utility rooms, cupboards and laundry areas
• Supplementary airflow in short duct runs or branch ducts

Key specifications

• Mounting type: inline installation for circular ducts
• Duct diameter compatibility: 100 mm
• Airflow direction: axial
• Intended use: exhaust or supply ventilation
• Operation mode: supports continuous or intermittent operation depending on wiring
• Application environment: bathrooms, kitchens, utility rooms, short localized duct runs
• Construction: compact in-duct housing suitable for concealed installation

How to use

Install the fan directly into a 100 mm circular duct section, ensuring secure mechanical fixation and correct airflow orientation toward the intended outlet or intake. Connect electrical wiring according to local regulations and the chosen operation mode: continuous run or switched/intermittent operation. Ensure accessible servicing clearance at the installation point and verify seals at duct connections to prevent air leakage. After installation, test for correct rotation and unobstructed airflow before completing duct sealing and insulation.

Usage recommendations

For reliable performance, match the fan to short or moderately resistive duct runs and avoid excessive bends or long stretches of narrow ducting. Use appropriate cable, switches and protection devices compliant with local electrical codes. Regularly inspect and clean the duct and fan housing to maintain airflow and reduce noise from debris buildup.
