Custom-Made Ventilation Fittings
Our company manufactures custom fittings for general ventilation, extraction, and smoke removal systems. Production is based on the customer's technical specifications (drawings, sketches) to solve complex installation challenges encountered during ductwork routing.
We offer the fabrication of parts in any configuration to bypass structural elements, connect ducts of different cross-sections, or link equipment with non-standard connection sizes.
Range of Manufactured Products
- Transitions/Reducers: Connecting elements for transitioning between ducts of different cross-sections (e.g., round to rectangular) and sizes. Available with central or offset axes.
- Elbows: Components for changing the direction of the ductwork at any non-standard angle.
- Tees and Crosses: Custom-sized fittings for creating branches from the main duct line.
- Offsets: Elements for parallel displacement of the duct axis to bypass obstacles (columns, beams, other utilities).
- Dampers: Devices with a sliding plate for manual regulation or complete shut-off of airflow in the duct.
- Tap-in Connections/Saddles: Fittings for neatly and securely connecting a branch to an existing duct.
- Ventilation Boxes: Custom-sized rectangular ductwork components.
- Equipment Adapters: Fittings for connecting ductwork to fans, heaters, filters, and other inline equipment.
- Deflectors and External Grilles: Custom-sized and designed components (RAL painting available).
Technical Specifications
Materials Used
- Galvanized steel: 0.5 to 1.2 mm thickness
- Stainless steel (AISI 304, AISI 430): 0.5 to 1.0 mm thickness
- Cold-rolled (black) steel: 0.8 to 1.5 mm thickness
Connection Type
- Seamed / Lock-formed
- Welded (for stainless and black steel products)
Coating and Painting
- Upon request, powder coating is available for products made from galvanized and black steel. The coating provides additional corrosion resistance and an aesthetic appearance.
- You can choose any color from the standard RAL palette. View the RAL color chart.
Manufacturing Technology & Quality Assurance
Every custom part is manufactured at our modern facility in Riga, Latvia. Our commitment to quality is backed by advanced technology and strict material control, ensuring each component meets precise technical requirements.
Precision Fabrication Technology
- Laser and Plasma Cutting: We use high-precision cutting technologies to achieve perfect geometry and clean edges for every component.
- CNC Bending: Our press brakes allow for accurate bending to any specified angle, crucial for complex fittings like offsets and elbows.
- Professional Welding: We employ TIG welding for stainless and black steel parts, creating strong, hermetic, and clean seams suitable for demanding applications.
Materials and Quality Control
- Certified European Steel: We work exclusively with certified steel from trusted European suppliers, including high-grade stainless steel (e.g., AISI 304) for corrosion resistance.
- Strict Standards: Our production process adheres to European manufacturing standards, guaranteeing the reliability and durability of our products.
How to Order
- Technical Specification: To calculate the cost and start production, we need a drawing or sketch of the part with all overall and connection dimensions, as well as the material type and thickness. You can send the specification via email.
- Quotation and Approval: Based on the information provided, we will calculate the cost and determine the manufacturing lead time.
- Production: After confirmation, the order is sent to the production workshop.
Ventilation System Installation
In addition to manufacturing individual components, SIA "Akvilon" offers professional installation services for ventilation systems. Our specialists ensure proper installation, integration, and commissioning of equipment to guarantee its design efficiency.
