The Maico wall sleeve WH 150 is an accessory for mounting fans or ventilators on walls or ceilings. It serves as an installation unit that securely and stably fixes the ventilator within the building component, with the sleeve being made of plastic. The construction allows for variable length, enabling adaptation to different installation conditions. The wall sleeve is specifically designed for a nominal size of 150 mm, making it suitable for ventilators with a diameter of 150 mm.

Applications
The WH 150 is used in installations where a ventilator needs to be mounted on a wall or ceiling. It is particularly useful in buildings with ventilation or air conditioning systems, where clean and secure fixation of the device is required. The sleeve is designed for indoor use, with material selection aimed at durable performance under normal environmental conditions.

Functions and Equipment in Detail
The wall sleeve features an extendable construction, allowing length adjustment between 200 mm and 500 mm. This provides flexibility during installation, depending on how deeply the ventilator needs to be inserted into the wall or ceiling. The external dimensions are 168 mm in width and 168 mm in height, with a depth of 500 mm at maximum extension. The sleeve is supplied in individual packaging with the same dimensions.

Technology Explained Simply
The sleeve is made of plastic, ensuring a lightweight yet stable construction. The weight is 1.35 kg, facilitating handling and installation. The required core hole in the building component must be at least 169 mm in diameter to allow correct installation of the sleeve. The variable length is achieved through a telescopic design, enabling adaptation to the respective wall or ceiling thickness.

Compatibility and Accessories
The WH 150 is specifically designed for ventilators with a nominal size of 150 mm. It is intended for wall and ceiling mounting and can be combined with corresponding fans designed for this mounting method.

Installation and Mounting
Installation is carried out by inserting the sleeve into a pre-drilled hole with a diameter of at least 169 mm. The length is adjusted according to the installation conditions, with a maximum depth of 500 mm. The sleeve is then connected to the ventilator, which is inserted into the sleeve. Fixation is achieved using the integrated mounting elements of the sleeve.

Operational Advantages
The variable length of the wall sleeve enables adaptable installation on different building components. The plastic construction ensures low weight and easy handling. The sleeve provides secure and stable fixation of the ventilator, minimizing vibrations and shifts during operation. The installation solution is suitable for indoor use and requires no additional mounting aids.

The wall sleeve WH 150 is a standardized accessory commonly used in ventilation technology.
