Reversibility

The Maico ECA 120 is a small room ventilator in standard configuration, designed for ventilating rooms with limited space requirements. It features a nominal size of 120 mm and is particularly suitable for surface mounting on walls. The device is characterised by a high air flow rate of 170 m³/h in a compact design, enabling efficient air movement without occupying much space. The rotational speed is 2600 1/min, and the ventilator is speed-controllable, allowing the air flow to be adjusted according to specific requirements. Control is achieved via phase-cutting, whereby a physically caused humming noise may occur in the lower speed range. The ventilator is not reversible and operates on alternating current with a rated voltage of 230 V and a network frequency of 50 Hz or 60 Hz. The power consumption is 19 W, and the maximum current draw (IMax) is 0.14 A. The conveying medium temperature at IMax is 40 °C. The sound pressure level is specified as 42 dB(A) at a distance of 3 m under free-field conditions.

Applications

The ECA 120 is suitable for use in residential and commercial rooms, particularly in bathrooms, kitchens or small ancillary rooms, where efficient and discreet ventilation is required. The protection class IP 45 allows use in protection zone 1 according to DIN VDE 0100-701, making it suitable for areas with increased humidity. The installation position is arbitrary, allowing flexible use in various installation scenarios. The installation method is surface-mounted, with the electrical connection optionally available for surface or flush mounting. Mounting is achieved via two clamp springs, enabling quick fixation in the pipe. The cover can be easily and quickly removed, facilitating maintenance and cleaning.

Functions and Equipment in Detail

The ventilator features a robust motor with ball bearings, designed for maintenance-free operation and continuous use. Protection class II ensures high safety without additional earthing. The housing is made of impact-resistant plastic and is finished in traffic white, similar to RAL 9016. The mains cable has a cross-section of 1.5 mm² and consists of three conductors. Additionally, protective seals are integrated to prevent condensation water ingress during ceiling installation. The device carries the VDE GS mark, except for the 24-V version.

Technology Explained Simply

Speed control is achieved via phase-cutting, a common method for regulating the power of alternating current motors. In this method, the voltage in the AC circuit is controlled over time to reduce the rotational speed. This enables flexible adjustment of air flow, although a humming noise may occur at low speeds, due to physical processes within the motor. Protection class IP 45 means the device is protected against splashing water from any direction, making it suitable for humid environments. The thermal overload protection function protects the motor from overheating and extends the device's service life.

Compatibility and Accessories

Various accessories are available to extend functionality. These include delay time switches such as the VZ 24 C (run-on time 1.5 to 24 min), VZ 6 (6 min), and VZ 12 (12 min), enabling controlled shutdown of the ventilator. A run-on relay (NRS 10) can also be used to set the run-on time. For protection against external influences, the external grille SG 120 is available, suitable for ventilation purposes. The plastic wall sleeve WH 120 is extendable and adapts to the pipe. An automatic closure flap AP 120 ensures the air flow stops after the ventilator is switched off. For speed control within an APo.UP installation, the speed controller STX 1.5 is available, rated up to 1.5 A.

Mounting and Installation

Mounting of the ECA 120 is done using two clamp springs, enabling quick and secure fixation in the pipe. The cover can be easily removed, simplifying cleaning and maintenance. The electrical connection is optionally available for surface or flush mounting, allowing flexible integration into existing installations. The installation position is arbitrary, so the ventilator can also be installed in unusual positions. The installation location is wall, with the standard configuration designed for surface mounting.

Operational Advantages

The ECA 120 offers a combination of high air flow volume and pressure strength in a compact design. The maintenance-free motor design and integrated thermal overload protection increase operational reliability. Speed control allows application-specific adjustment of air flow, enabling energy savings. Protection class IP 45 and integrated protective seals make the ventilator suitable for humid environments. The simple mounting and removal of the cover facilitate maintenance. The traffic white colour, similar to RAL 9016, blends visually into many interior spaces.
