Rectangular ducting. Rectangular air ducts are a fundamental component of ventilation systems in residential, commercial, and industrial buildings. Their flat design makes them ideal for installations in tight spaces like ceilings and walls.
We offer galvanized steel ducts that are corrosion-resistant and comply with EU standards. Available in various sizes with matching fittings such as elbows, transitions, and flanges. Suitable for all types of HVAC projects. Fast delivery in Estonia and Europe.
It supplies fresh air and removes stale air while a heat exchanger transfers warmth from extract to supply. You get lower heating bills, stable indoor climate, lower CO₂ and humidity, and less risk of mould.
We size by floor area/volume and target air changes, check routing for ducts and your budget. Apartments often suit compact or decentralised units; houses and commercial spaces usually use central HRV/MVHR. We match airflow, controls and accessories.
As a rule of thumb, ~0.5 air changes per hour in living areas plus peak extraction in wet rooms. Undersizing raises noise and worsens air quality; oversizing wastes money. We provide a load calculation and balancing.
Common pairs: G4 pre-filter + F7/ePM2.5 fine filter. Replace every 3–6 months depending on dust and season. Fine filtration protects the heat exchanger and helps allergy sufferers (pollen/PM2.5).
Typical locations: utility room, attic or service cupboard. You need condensate drain, power supply, safe access for service, sized ducts, distribution boxes and diffusers. We plan routing and mounting.
Yes. If running main ductwork is difficult, decentralised room units work well. In retrofits we consider thermal bridges, condensate management and acoustic treatment.
They keep ventilation demand-driven, improving air quality while saving energy. Smartphone control is available; bypass and pre-heaters protect efficiency in cold weather.
It depends on airflow class, heat-exchanger type and efficiency, controls, required noise levels and accessories (ducting, silencers, filters), plus installation and final balancing. We prepare a clear, project-specific quote.
In our online store, stock items are available immediately, while special models are made to order. We deliver across the Baltics (Estonia, Latvia, Lithuania). If desired, we provide a turnkey solution: design, supply, installation, commissioning, and balancing—for any type of property (residential, commercial, industrial). Explore our projects.
