The NEST TITANIUM Antibacterial Ventilation Duct (DN90/75) represents the pinnacle of air distribution technology for modern heat recovery systems. This 50m coil is engineered to provide a hygienic, quiet, and energy-efficient conduit for fresh air in residential, commercial, and high-demand environments. Featuring a unique double-wall construction and patented antimicrobial protection, it ensures that the air you breathe remains as pure as when it left the filtration unit.
Advanced Antimicrobial & Structural Technology
Active Microbial Shield
The internal layer is infused with silver and copper ions, providing lifetime protection against 100% of bacterial and fungal colonies (ISO 22196:2011). Unlike coatings, this protection is integrated into the polymer matrix and will not migrate or wash away.
Anti-Static Performance
Proprietary antistatic additives prevent the buildup of static electricity on the internal surfaces. This drastically reduces dust accumulation over years of operation, maintaining system hygiene and reducing the need for professional duct cleaning.
Certified Food-Safe
Constructed entirely from modified high-density polyethylene (HDPE), the duct is fully approved for contact with food. This guarantees that no volatile organic compounds (VOCs) or harmful odors are released into your home's air supply.
Acoustic Comfort
The double-wall design features a corrugated outer layer for strength and an ultra-smooth internal layer for low air resistance. The internal air pockets between layers act as a natural sound dampener, suppressing airflow noise even at higher velocities.

Profi vs. Premium Titanium Variants
NEST TITANIUM ducts are available in two levels of antimicrobial protection to suit different building requirements:
Our antibacterial ducts are part of the complete VENTIT ecosystem. They are designed for a 'perfect fit' with our distribution boxes, manifolds, and valves, ensuring airtight connections without the need for additional gaskets or tapes in most standard installations.
