Heat recovery unit dummy (cover) SpiroFlex E-RVC3HEB-OB for rekuperators, model E-RVC3HEB-OB

SpiroFlex E-RVC3HEB-OB is a dummy/cover designed for heat recovery ventilation units. It serves as a non-operational placeholder or protective cap for the specified model, protecting duct openings and internal components during installation, maintenance, transport, or storage. The cover helps keep ventilation channels sealed from dust, debris and insects and is compatible with SpiroFlex heat recovery systems of corresponding dimensions.

Advantages

The dummy cover provides a durable barrier that prevents contamination of ducts and unit interiors without affecting existing ventilation connections. Constructed to fit the specified unit profile, it is lightweight, easy to mount and remove, and minimizes the risk of accidental damage to sensitive components. The cover reduces time spent on site by allowing installers to protect openings quickly during staged installation or repair work.

Suitable for

• Protecting duct ends and ventilation openings during installation or maintenance
• Temporarily sealing systems during transport and storage
• Keeping debris and insects out of inactive or unfinished ventilation branches
• Use as a non-operational placeholder in system balancing or configuration stages

Key specifications

• Purpose: non-operational cover for heat recovery ventilation units
• Compatibility: designed for SpiroFlex ventilation systems of matching dimensions
• Function: protects duct openings and internal components from dust and debris
• Material characteristics: lightweight protective construction suitable for repeated mounting
• Use conditions: intended for installation, maintenance, transport, and storage situations

How to use

Place the dummy cover over the designated duct opening or unit flange, ensuring a secure fit according to the unit’s connection profile. No electrical or airflow connections are required. Fasten or support the cover as needed to prevent displacement during handling or storage. Remove the cover before commissioning the ventilation unit or restoring normal airflow, and inspect adjacent seals and components for any debris accumulated while the cover was in place.

Usage recommendations

Use the cover during all non-operational phases of work to maintain cleanliness of ducts and to protect internal components. Store the cover in a dry environment when not in use and avoid exposing it to sharp objects or sustained mechanical stress that could deform the fitting.
