General Aspiration (GDA): Central Engine Units

Sizing Guide: How Much Power Do I Need?

The central vacuum cleaner should be chosen based on the total square footage of the home and the number of wall outlets installed. A central vacuum cleaner that is too weak will not extract sufficiently from the most distant outlets.

Calculate the ideal coverage:

• Basic Models (Air Watt < 400): Ideal for small apartments (up to 100-150 m2) or for systems with few wall sockets.
• Medium Power Models (500-650 Air Watts): The universal choice for single-family homes and villas (up to 250 m2). Perfect for intensive domestic use.
• High Power models (Air Watt > 700): For large complexes, hotels, offices or very long houses with multiple suction points.

Bag or No Bag?

GDA core systems offer both:

• Filter Bag: Dust is collected in a disposable bag. The most hygienic solution and recommended for allergy sufferers.
• Bagless (Cyclone): Dust settles in the dust bin. This is a more environmentally friendly solution, but requires regular emptying and cleaning of the filter (which is dustier).

Frequently Asked Questions (FAQ)

1. Can I install the central vacuum cleaner myself?
Connecting the central unit to the suction point and to the electricity can be done by DIYers, provided that the wall system has already been properly installed (pipes and sockets).

2. How much noise does the central unit make?
Professional GDA central air conditioners are designed to be quiet. Most noise comes from the air entering the ducts. If installed in a garage, basement, or utility room, the noise will not be audible in the living areas.

3. What is Soft Start?
Soft Start is an electronic system that starts the engine gradually. This reduces peak current draw at start-up (protecting the 3kW meter) and increases engine life.
