Features and Benefits
Easy installation
The wall mounting brackets are part of the fan housing, and the unit is equipped with a simplified, pre-wired electrical system.
Space-saving
A compact design that fits in tight spaces, such as crawl spaces, attics, or closets.
Easy maintenance
The top cover can be easily removed for inspection and maintenance.
Low noise
Acoustic self-extinguishing foam lining for sound absorption.
Tested in accordance with the latest standards
Tested in accordance with the latest standards: the devices are tested at Aerauliq, a laboratory accredited by TÜV Rheinland, which ensures accurate and up-to-date information on electrical safety, performance, and noise levels that you can trust. SFP (Specific Fan Power) measured at an independent BRE laboratory (United Kingdom). Designed and manufactured in accordance with the EN 60335-2-80 standard (Low Voltage Directive) and the EMC Directive (Electromagnetic Compatibility).
Specifications
Construction
The housing of the outdoor fan is made of powder-coated galvanized sheet steel, which ensures a durable and sturdy construction.
Finishing
The unit is finished in white (RAL 9010). The outer casing must be made of strong, durable ABS plastic.
Engine
To ensure energy savings, EC external rotor motors are included as standard equipment. They are equipped with integrated thermal protection, mounted on sealed, long-life ball bearings and vibration-damping mounts.
Work wheel
An exemplary centrifugal fan is dynamically balanced and driven directly by a motor to ensure a smooth airflow through the unit.
Configurability
Multiple exhaust points to simultaneously remove condensate from wet areas and stale air from the kitchen and utility rooms.
Application
A mechanical exhaust system for the entire building, suitable for installation on walls, ceilings, and floors, in either a horizontal or vertical orientation. Designed for connection to self-regulating exhaust fans.
Operation
Humidity Control Version
QCMEV125 HY/HYP
The unit is equipped with a built-in humidity sensor. Regardless of the selected operating mode and speed setting, the fan speed is increased by 15% when the humidity threshold is reached. If the humidity level drops below the threshold, the fan continues to operate at the increased speed for a preset period of time.
Optional equipment for the QCMEV125 and QMEV125HY models
Humidity Control Version with Control Panel QCMEV125HYP
The device is equipped with an integrated humidity sensor and a multifunctional control panel (CTRL-V) to ensure ease of use and convenience.
