Due to the new Duo central unit, acquiring a central vacuum cleaner no longer depends on the size, installation, or installation location of the central unit. The Duo unit is compact and can be located within the apartment freely. It is meant especially for city homes, terraced houses, and leisure residences. Because the Duo central unit can be installed either horizontally or vertically, it can easily be installed in narrow spaces. It is also suitable for apartments where the exhaust air blow-out pipe can not be installed.  The Duo is 440 mm wide, 300 mm high, and it only weighs 5.5 kg. It can be installed almost anywhere due to its light weight and the opportunity to select the installation position. The stylish black and silver or white and silver design fits into various styles of homes and enables even more installation location options. Despite its compact size, the Duo has a 10 litre dust canister with a micro fiber dust bag as standard accessory. The convenient holder enables easy and hygienic emptying of the canister. It has sufficient power to clean a home with a maximum dust pipe length of 30 m. If the exhaust air can not be blown out from the apartment, a Duo Aparto Kit installation kit is installed. The Duo Aparto Kit includes a wall inlet and a HEPA exhaust air filter, and the exhaust air is filtered into the installation location of the central unit.
