Round Ducts and Fittings from a Manufacturer in Riga
SIA "Akvilon" is an experienced Latvian manufacturing company with over 30 years of expertise in sheet metal processing. We offer comprehensive solutions for round ventilation systems, combining our in-house production of custom elements with a stocked warehouse in Riga, where we maintain an inventory of the most in-demand components.
Our approach allows us to supply everything necessary to create modern, efficient, and reliable ventilation systems for both private homes and large commercial properties.
A Comprehensive Approach: From Design to Project Supply
We assemble and supply complete equipment sets for projects of any scale. Our key capabilities include:
- Engineering Design and Selection: Our specialists will perform the necessary calculations, select the appropriate equipment, and prepare a complete specification for your project and budget.
- Our Own Warehouse in Riga: We maintain a stock of standard ducts, fittings, and fans, which allows us to promptly fulfill orders.
- Custom Manufacturing: We quickly produce large-diameter ducts and any non-standard items according to your drawings, from complex transitions to Y-pieces.
- Full Project Kitting: We combine our own manufactured products with items from trusted European partners to offer a wide range of technical solutions.
- Convenient Ordering and Delivery: Purchase standard components from our online store or contact us for project kitting. We organize delivery throughout Latvia.
Why Round Ventilation is the Industry Standard
In most projects, round ducts are the preferred choice due to their fundamental technical advantages:
- High Aerodynamic Efficiency: A circular cross-section creates minimal resistance to airflow, which reduces the load on the fan and saves electricity.
- Rigidity and Airtightness: The spiral-wound manufacturing technology gives the ducts extra rigidity, and using fittings with EPDM gaskets makes it easy to achieve high airtightness classes (C and D).
- Cost-Effectiveness: Manufacturing round ducts requires less sheet metal compared to rectangular counterparts of the same cross-sectional area, which reduces their cost.
- Ease of Installation and Maintenance: The standard length of straight sections (3 meters) reduces the number of joints, speeding up installation. The smooth inner surface with no corners simplifies system cleaning.
All Components for Any System Complexity
Our assortment includes all the components necessary for the complete assembly of a ventilation system of any scale and purpose.
The core of the network consists of rigid spiral-wound ducts, for which we produce and supply a full range of fittings: elbows, reducers, T-pieces, crosses, saddle taps, and end caps. For connecting terminal equipment in hard-to-reach places, flexible corrugated ducts are used.
For airflow control and safety, our range includes dampers for balancing, backdraft dampers to prevent reverse airflow, and certified fire dampers. Air quality is ensured by cassette filters and full-fledged filter boxes.
Acoustic comfort and ease of operation are ensured by elements such as round silencers (reduce noise), flexible connectors (dampen vibration from equipment), and inspection hatches (provide access for maintenance).
Quality Materials and Compliance with Standards
All our products for round ventilation systems are manufactured in strict accordance with European standards, which guarantees their quality, durability, and the full compatibility of all elements.
- Materials: The standard material is high-quality galvanized steel (DX51D+Z275). For facilities with special requirements (food industry, corrosive environments), we manufacture elements from stainless steel (AISI 304, AISI 316). For design-focused projects, powder coating in any RAL color is available.
- Standards: Our products comply with key EU norms, including EN 1506 (guarantees dimensional accuracy and component compatibility) and EN 12237 (allows for the creation of systems with high airtightness classes C and D).
Professional Installation
In addition to project kitting, we also offer ventilation system installation services for those who require a turnkey solution. Our experienced teams carry out work in compliance with all construction regulations.
Quality Assurance and Certification
All our products are certified according to European standards. Round ventilation systems comply with EN 1506 (dimensions) and EN 12237 (strength and leakage). Load-bearing steel structures are manufactured according to EN 1090. This is your guarantee of safety and durability.
