Axial exhaust fan CATA E-100 GTH 00900239 — 100 mm diameter

The CATA E-100 GTH axial exhaust fan is a compact ventilation unit with a 100 mm diameter impeller designed to extract air from small rooms, bathrooms, kitchens and service spaces. It is intended for situations that require a directed, constant air extraction through a 100 mm duct connection and can be installed inline or mounted to a wall. The fan provides efficient removal of moisture, odors and stale air to help maintain acceptable indoor air quality in confined spaces.

Advantages

The axial design delivers focused airflow with a small footprint, making the unit suitable for tight installation spaces. Its 100 mm diameter impeller supports standard small-diameter ductwork and simplifies connection. Construction and mounting options allow for either inline or wall installation, offering flexibility for different ventilation layouts. The fan’s straightforward mechanical design is easy to integrate with basic ventilation circuits and is compatible with standard bathroom and kitchen extraction needs.

Suitable for

• Ventilation of bathrooms and toilets in residential or small commercial properties
• Air extraction in small kitchens, pantries and utility rooms
• Service rooms, storage spaces and cupboards requiring periodic ventilation
• Inline duct runs or wall-mounted exhaust installations with a 100 mm connection

Key specifications

• Impeller diameter: 100 mm
• Axial fan type for directed airflow
• Compact housing suitable for limited space installations
• Designed for wall or inline mounting
• Connection suited to 100 mm diameter ducting

How to use

Install the fan in-line within the duct run or mount it on a suitable wall opening where a 100 mm duct connection is available. Ensure electrical connection is performed in accordance with local regulations and by a qualified installer. Position the fan so air is expelled to the outside and not into adjacent enclosed spaces. For consistent performance, check that the duct path is as straight and short as practical and that any grills or covers are compatible with the fan’s airflow direction.

Recommendations

For reliable operation, combine the fan with a properly sized 100 mm duct, use smooth bends where necessary, and avoid long, restrictive duct runs. Regularly inspect and clean the impeller and housing to prevent dust build-up; disconnect power before maintenance. If the installation serves a bathroom or kitchen, consider a simple timer or humidity sensor switch to improve moisture control and energy use.
