Exhaust hoods

Professional Exhaust Hoods from the Manufacturer

SIA "Akvilon" is a Latvian manufacturer with 30 years of experience, designing and producing professional stainless steel exhaust hoods. We create practical and affordable engineering solutions for facilities of any scale: from professional kitchens and food production facilities to industrial workshops, welding stations, and laboratories. A properly engineered ventilation hood is not just an element of comfort, but a key component that ensures fire safety (by removing flammable grease aerosols), sanitation (preventing bacterial growth), and the protection of your assets—equipment and finishes—from the damaging effects of steam and grease.

Our Approach and Key Advantages

• Budget-Friendly Solution: Our exhaust hoods are produced at our own factory in Riga, allowing us to offer one of the most competitive prices on the market. It's a practical choice for standard local extraction tasks.
• Custom Manufacturing. We do not offer standard solutions; instead, we manufacture each hood to the customer's individual dimensions, precisely matching the geometry of the room and the layout of the equipment.
• Custom Solutions. In addition to our standard series, we manufacture custom-designed exhaust hoods, solving the most complex technical and design challenges.
• Manufacturing Precision: Sheet metal is cut using laser cutting machines, which ensures the precise geometry of all parts and their correct fit during assembly.
• Quality Materials and Finishes. For production, we use certified stainless steel (AISI 430, AISI 304, and acid-resistant AISI 316L). For custom design solutions, we also offer galvanized steel hoods with powder coating in any RAL color.
• Welded Construction. Unlike modular counterparts, our hoods have a welded body. This design reduces the number of joints, which lowers the risk of grease and condensate leakage.
• Efficient Grease Filters. At the customer's choice, hoods are equipped with labyrinth or mesh filters. We recommend labyrinth filters as the most effective solution: as the air passes through their curved channels, its direction changes multiple times, causing heavier grease particles to inertially settle on the walls and drain into the grease collector.
• Thoughtful Details. Each hood comes standard with a welded grease collection channel and a drain cock for easy maintenance.

Types of Exhaust Hoods We Produce

We manufacture hoods in various configurations to solve specific technical tasks.

Hoods with Grease Filters (For Kitchens & Similar Applications):

• Wall-Mounted (Article: AFS): Installed against a wall over a line of heating equipment.
• Island (Article: AFC): Mounted to the ceiling above equipment located in the center of the room.
• Supply-and-Exhaust (Article: AFP): Simultaneously exhaust contaminated air and supply fresh make-up air, compensating for the vacuum and improving the microclimate.

Hoods without Filters (For Steam & Non-Greasy Fumes):

• Steam Hoods (Article: BFN): A simplified design for extracting water vapor, hot air, and non-greasy fumes. Used above dishwashing equipment, cooking kettles, in bakeries, or other industrial facilities.

Hoods for Industrial & Special Applications:

• Spark Arrestor Hoods: For equipment using open flames (barbecues, grills, wood-fired ovens) or processes that generate sparks (e.g., welding stations), we manufacture specialized exhaust hoods with mandatory installation of spark arrestor filters. This is a critical fire safety requirement that prevents hot particles from entering the ventilation duct.

Key Parameters for Selection and Installation

Correctly selecting the size and installation height of the hood is key to its effective operation. We recommend adhering to the following technical parameters, based on years of experience and aerodynamic calculations.

Optional Features and Accessories

Upon your request, we can equip the hood with additional equipment and supply related materials for a complete finish of the work area:

• Integrated Lighting: Installation of sealed LED lights with a high protection class (IP65), designed for use in high humidity and temperature conditions.
• Decorative Wall Cladding: Supply of protective stainless steel wall panels.

Comprehensive Solutions and Compliance

SIA "Akvilon" offers not just a standalone product, but a comprehensive functional solution. We are ready to perform the full cycle of work:

• Consultation and on-site measurements.
• Aerodynamic calculation and selection of the optimal hood configuration.
• Manufacturing at our facility in Riga.
• Production of all related components: ducts, fittings, and fasteners.
• Professional installation and integration of the hood into the overall ventilation system.

It is important to understand that a powerful exhaust system requires a properly organized make-up air supply. Without it, a vacuum is created in the extraction zone, which reduces ventilation efficiency and can lead to backdrafts. Our engineers design balanced systems by creating a correct pressure cascade (slight negative pressure in the extraction zone, positive pressure in adjacent clean areas like dining halls or offices), ensuring that air flows from clean zones to "dirty" zones and completely preventing contaminants and odors from spreading.

Compliance with European and Local Standards

The design and operation of professional ventilation are strictly regulated. Non-compliance with these standards entails risks of fines, business suspension, and, most importantly, a threat to safety. We guarantee that our solutions meet all key requirements for your industry.

For Professional Kitchens and Food Production:

The main focus here is on hygiene and fire safety, regulated by food safety authorities (like PVD), fire and rescue services (VUGD), and EN 16282 standards.

For Industrial Workshops and Production Facilities:

In industrial settings, occupational safety requirements, regulated by the State Labour Inspectorate (VDI), are paramount. The main goal is to ensure a safe working environment for staff.

Operation and Fire Safety

Regular cleaning of the exhaust system from grease deposits is not just a recommendation but a critical fire safety requirement. According to the Cabinet of Ministers Regulation No. 238 "Fire Safety Regulations" in Latvia, cleaning must be carried out frequently enough to ensure that the thickness of combustible deposits (grease) does not exceed 1 mm. Neglecting this rule creates a high risk of fire.

We strongly recommend entering into a contract with a specialized service organization for the periodic cleaning of the ductwork. The recommended frequency depends on the intensity of the facility's operations:
