The Maico ECA piano Standard is a small-room fan for surface mounting, designed for use in bathrooms, kitchens and other damp rooms. It features a standard version with integrated backdraft damper and is designed for a nominal size of 100 mm. The device is operated via a light switch or a separate switch and allows for speed control, where a physically caused humming noise may occur at low speeds due to phase-cut technology. The cover can be removed without tools, simplifying cleaning. The housing is made of impact-resistant plastic and is finished in traffic white, similar to RAL 9016. The integrated backdraft damper is springless, durable and robustly constructed. The fan is equipped with a thermal overload protection and features a robust motor with ball bearings, which is maintenance-free and suitable for continuous operation.

Applications

The fan is intended for use in protection zone 2 according to DIN VDE 0100-701, making it suitable for bathrooms and other damp rooms. The protection class IP X4 ensures protection against splashing water, increasing safety in the bathroom. The installation type is surface-mounted, with both wall and ceiling mounting possible. For ceiling mounting, a hole in the cover is required. The installation orientation is arbitrary, allowing flexible installation in various rooms.

Functions and Equipment in Detail

The fan provides a flow rate of 80 m³/h at a speed of 2400 1/min. The rated power is 8 W, and the maximum current consumption (IMax) is 0.06 A. The rated voltage is 230 V at a network frequency of 50 Hz or 60 Hz. The supply cable has a cross-section of 3 / 1.5 mm². The sound pressure level is 26 dB(A) at a distance of 3 m under free-field conditions, indicating particularly quiet operation. The Piano impeller ensures low noise generation. Protection class II and the VDE mark confirm electrical safety.

Technology Explained Simply

Speed control is achieved via phase-cut, a common method for controlling the speed of AC motors. Here, the voltage to the motor is reduced by cutting off portions of the AC voltage cycle, which reduces the speed. At low speeds, this may cause a humming noise, which is physically inevitable and does not indicate a defect. The thermal overload protection protects the motor from overheating by automatically interrupting operation if the temperature becomes too high. The integrated backdraft damper prevents air from flowing back when the fan is not running, which is particularly important for kitchen and bathroom ventilation.

Compatibility and Accessories

The ECA piano Standard is compatible with ECA 100 ipro and predecessor models DN 100, with identical screw hole positions and cable entry. This allows for easy replacement. Available accessories include various delay timers (e.g. VZ 6, VZ 12, VZ 24 C), a run-on relay (NRS 10), a speed controller (STX 1,5), a mounting plate (ZM 11), a wall sleeve (WH 100), an outer grille (SG 100) and a closure flap (AP 100). These components can be used additionally depending on the application to extend the functionality of the fan.

Installation and Mounting

Installation is done via surface mounting, with the cover removable without tools, simplifying installation and maintenance. Wall and ceiling mounting are possible, with a hole in the cover required for ceiling mounting. Electrical connection is made via concealed wiring. The installation orientation is arbitrary, allowing the fan to be installed in various orientations. Dimensions are 151 mm (width), 151 mm (height) and 104 mm (depth). The device weighs 0.5 kg.

Operational Advantages

The fan is characterised by particularly quiet operation, making it suitable for living spaces. The maintenance-free design with ball bearings and the integrated thermal overload protection increase reliability. Easy installation and compatibility with predecessor models simplify replacement. Protection class IP X4 and protection class II ensure safe use in damp rooms. The integrated backdraft damper prevents air from flowing back, improving indoor air quality.
