A supply and exhaust system with a recuperator is a modern solution for ensuring high-quality air exchange in a room. It simultaneously removes polluted, exhaust air and supplies fresh, clean air from outside. The key feature of such a system is the recuperator (heat exchanger), which transfers heat from the exhaust air to the cold supply air. Thanks to this process, the system significantly reduces heating costs in winter, as there is no need to additionally heat the incoming air. In summer, the recuperator works in the opposite direction, keeping the interior cool and reducing air conditioning costs. As a result, the system creates a comfortable microclimate, maintaining optimal temperature and humidity, as well as filtering the air from dust and allergens.

Duct fans are suitable for installation in rectangular ventilation ducts. They can be used in residential, commercial and industrial buildings.

Round duct fans are designed for installation in round ducts. They are ideal for use in supply, exhaust or supply-exhaust ventilation systems. These fans are compact, easy to install and suitable for creating both general and local ventilation systems in residential, commercial and industrial premises. Thanks to their design, they offer high performance with relatively low noise levels.

A radial (or centrifugal) fan is a device that is mainly used in exhaust systems. Due to its design features, this type of fan is well suited for removing heavily polluted air or air containing various particles or impurities. The fan's design allows it to create high pressure and move large volumes of air even through long air ducts. It is often used for kitchen exhaust systems with hoods.

A stainless steel exhaust hood is professional equipment for capturing and removing air with high fat, moisture and flavour content. It is exceptionally durable, hygienic and corrosion-resistant, making it ideal for use in restaurants, cafés and food processing facilities. The smooth, non-porous surface of stainless steel is easy to clean and meets strict sanitary standards.

A galvanised steel exhaust hood is a ventilation system component designed to capture and remove impure air, vapours and grease fumes. It is made of galvanised steel, which makes it resistant to corrosion and moisture, as well as relatively inexpensive. These hoods are widely used in industrial workshops and commercial kitchens.

Supply ventilation is a system that provides fresh, clean air from outside into a room. Unlike natural ventilation, it uses fans to force air into the room and may also include filters for purification and heaters for warming during the cold season. This system creates excess pressure inside the room, which prevents dirty air from entering through gaps and doors. Supply air units are equipped with a comprehensive automation system that not only controls the operation of the unit, but also monitors air quality and the technical condition of the system.

Fan speed controllers are devices that allow to change the performance of a ventilation system and save energy. The two most common types are simistor and frequency controllers. The choice of a specific type depends on the fan power, motor type and system requirements.
