Decentralized ventilation units and accessories

This category provides components and accessories for decentralized ventilation units in the IVAR HRC series. These include replacement filter cartridges, recuperation inserts, external grilles, and mounting templates. They are suitable for use in residential and commercial buildings where controlled mechanical ventilation with heat recovery is required.

The products support both analog (HRC S) and electronic (HRC E) versions of the system. The Master unit in the analog system can control up to three Slave units, while the electronic version allows control of up to eleven Slave units. Accessories are designed for easy installation and maintenance, with features such as quick-release mounting and UV-resistant materials.

How to choose

• Match the accessory to the unit model (e.g., IVAR.HRC SM, IVAR.HRC EM) and airflow capacity.
• Ensure compatibility with the connection size and thread type of the ventilation ductwork.
• Choose materials suited to the installation environment, such as antistatic and UV-resistant grilles for external use.
• Verify the power supply requirements, such as 230 V for the Master unit and 12 V transformer for control components.
• Consider the number of Slave units the Master unit can control based on the system version (analog up to 3, electronic up to 11).
