Motorized shutter MVK65 (for 650 mm nominal size)

Motorized Shutter for Large Nominal Sizes

The motorized shutter MVK65 (for 650 mm nominal size) is a high-quality solution for wall fans in ventilation systems, suitable for both exhaust air and supply air. This specific variant is ideal for preventing cold air ingress when the fan is off and keeping out dirt, birds, and insects. The motorized shutter only opens when needed and offers a suitable solution for your ventilation needs.

The Motorized Shutter MVK65 is made from robust, UV-resistant plastic and features a powerful motor that operates at a voltage of 230 volts ~50 Hz. It is suitable for temperatures ranging from -20 to +60 °C and opens automatically when voltage is applied, closing when voltage drops due to an integrated spring support. This shutter is stable up to a maximum airflow velocity of 10 m/s and has an IP 51 rating against dripping water.

In addition to the MVK65 variant, there are several other models that differ in nominal size, including:

• MVK15 (for 150 mm nominal size): Ideal for smaller applications, easy to install.
• MVK20 (for 200 mm nominal size): Provides a larger airflow area for medium applications.
• MVK80 (for 800 mm nominal size): For larger ventilation systems requiring a high volume of air.

The decision on the right variant depends on various factors, including the size of the ventilation system and the required airflow rate. To facilitate selection, we have summarized the key similarities and differences of the various variants in the following list:

• Material: All variants are made from UV-resistant plastic.
• Operating Temperature: All models are suitable for temperatures from -20 to +60 °C.
• Protection Class: All models feature IP 51 protection against dripping water.
• Motor: All variants use a 230V ~50 Hz motor.
• Application Area: The choice of nominal size (NW) determines the application possibilities in various ventilation systems.
