Exhaust/ventilation fan MONROE 125X1 – inline pull-out ventilator Ø125 mm

MONROE 125X1 is an inline pull-out ventilation fan with a 125 mm duct connection designed for exhaust and general ventilation tasks. The unit is compact and intended for installation inside duct runs where discreet airflow extraction is required. Its construction supports residential and light commercial environments such as bathrooms, kitchens and utility rooms, providing basic ventilation performance with straightforward mounting and duct compatibility.

Advantages

The inline design allows installation away from the room, reducing noise in occupied spaces while maintaining effective airflow. A 125 mm connection ensures compatibility with common round duct systems and offers a balance between airflow capacity and space-saving dimensions. The pull-out configuration simplifies access for inspection and maintenance without removing the entire unit from the duct system.

Suitable for

• Bathroom exhaust ventilation
• Kitchen ventilation for small to medium kitchens
• Utility rooms and laundry areas
• Supplemental ventilation in small commercial premises

Key specifications

• Duct connection diameter: 125 mm
• Inline pull-out fan design for installation inside duct runs
• Intended use: exhaust and general ventilation
• Application environment: residential and light commercial
• Mounting: designed for integration into circular ductwork

How to use

Install the MONROE 125X1 inside a compatible 125 mm duct run following local electrical codes and mounting guidelines. Position the fan so the pull-out mechanism is accessible for periodic inspection. Connect the electrical supply according to the wiring instructions supplied with the unit, ensuring power is isolated during installation. Balance the duct layout to minimise bends and restrictions that reduce airflow, and secure all duct joints to prevent leakage.

Usage recommendations

For best performance, use the MONROE 125X1 in straight or gently curved duct sections and avoid long runs with multiple tight bends. Regularly check and clean the fan and ducting every 6–12 months depending on use and environmental conditions. When replacing or upgrading ventilation, verify that the 125 mm duct size and airflow capacity match the room’s ventilation requirements and local ventilation standards.
