Fans

Fan Selection: From Domestic to Industrial Solutions

Fans are the heart of any mechanical ventilation system, from a small bathroom to a large industrial facility. They are responsible for supplying fresh air, exhausting stale air, and creating the necessary pressure to transport it through ductwork. Today, the key criterion for selecting a professional fan is not only its performance but also its compliance with strict European energy efficiency standards.

As an engineering company with over 30 years of experience, SIA "Akvilon" provides professional selection, supply, and installation of domestic and industrial fans. We offer solutions from trusted European manufacturers that not only provide the required air exchange but also ensure legal compliance with the EU's Ecodesign Directive (ErP) and deliver significant energy savings.

Fan Types and Technical Features

Choosing the right fan depends on the specific task: performance, system resistance, and operating conditions. Our 30 years of experience allow us to select the optimal solution for any project, guaranteeing its efficiency and legal compliance.

Duct Fans

Installed directly into ductwork, these are among the most common fan types. We offer several models:

• Round Duct Fans: Universal models in a galvanized steel housing. Models up to 160 mm in diameter (with power below 125 W) are exempt from strict ErP regulations, making them a simple choice for smaller systems. For more powerful models (200 mm and up), we offer versions with modern EC motors for ErP compliance and maximum savings.
• Rectangular Duct Fans: Robust industrial fans from S&P with a high protection class (IP55) and a wide operating temperature range (-40/+70°C). All models are over 125 W and require speed controllers or frequency converters for ErP compliance. Ideal for restaurants, car parks, and manufacturing facilities.
• Low-Noise Duct Fans (SILENT): Premium fans from S&P with a sound-absorbent casing. Their noise level (from 23 dB) is comparable to a whisper, making them the perfect choice for noise-sensitive applications like offices, medical facilities, and homes.

Centrifugal Fans

These fans generate high pressure, which is necessary for long duct runs with filters and other equipment.

• Standard Centrifugal Fans (CMT): Industrial workhorses from S&P. Their performance data is verified by ISO 5801 tests. Except for the smallest model (90 W), all fall under the ErP directive and require a frequency converter for efficient operation, providing flexible control and energy savings.
• High-Temperature & Smoke Extraction Fans (CRMT): Fire safety equipment. These S&P fans are F400-120 certified, guaranteeing operation at 400°C for 2 hours to extract smoke and ensure safe evacuation. This is a mandatory component for many commercial and public buildings.

Axial Fans

Designed to move very large volumes of air against low resistance.

• Industrial Axial Fans (HCFT): Powerful units in a robust steel casing (IP55) for ventilating factories, warehouses, and workshops. Models up to 315 mm (with power up to 125 W) are exempt from ErP. More powerful versions use frequency converters to comply with regulations.
• Compact Axial Fans (TCBB/TCBT): Solutions for installations with limited space, thanks to a motor integrated into the impeller hub. Ideal for in-duct mounting.

Roof Fans

Provide centralized exhaust from a building. We offer two main types from S&P:

• Universal Roof Fans (MIXVENT-TH): Low-profile and versatile models for all types of buildings, from private homes to shopping centers. The smallest model (63 W) is exempt from ErP.
• Smoke Extraction Fans (CTHT): Certified F400-120 safety equipment for smoke extraction systems. Also suitable for continuous exhaust of hot air (up to 120°C) from industrial kitchens.

Domestic Fans

All models have a power rating well below 125 W and are exempt from ErP requirements, which simplifies selection. Their main purpose is to combat humidity and odors in restrooms.

• Standard Fans (DECOR): A reliable and affordable solution. Equipped with a backdraft shutter as standard. Options with a timer and humidity sensor are available.
• Designer Silent Fans (SILENT-DESIGN): Premium models for those who value comfort. They operate almost silently (from 26.5 dB) and are available in various colors to match any interior design.

Fireplace Fans

Turn a fireplace into an efficient heating system. All models are heat-resistant (up to +150°C) and are exempt from ErP. We offer duct models (VOK) for smaller systems and more powerful centrifugal models (KAM) for larger homes with extensive ductwork.

Automation: The Brain of Your Ventilation System

Properly selected automation is the key to efficiency, safety, and regulatory compliance. We offer a full range of components:

• Speed Controllers and Frequency Converters (VSDs): Allow precise control over fan performance. For powerful 3-phase motors, a VSD is a mandatory component for ErP compliance.
• Sensors (CO₂, Humidity, Pressure): Enable "Demand Controlled Ventilation" — the system runs only when needed, saving up to 80% on electricity.
• Damper Actuators: We offer reliable actuators from the world leader, Belimo, to create controllable and zoned ventilation systems.
• Duct Heaters: Provide comfortable heating of supply air and protect equipment from freezing.

Compliance with the ErP Directive

Since 2015, the Ecodesign Directive (ErP 2009/125/EC) has been in force throughout the European Union. It sets strict energy efficiency requirements for fans with a power input between 125 W and 500 kW. The purchase and installation of non-compliant equipment is a violation of legislation.

By choosing equipment supplied by Akvilon, you can be sure you are receiving a solution that is not only high-performing but also fully legal, energy-efficient, and modern, helping you avoid issues with regulatory authorities and reduce operating costs.

Regulatory Requirements in the EU

In addition to pan-European directives, ventilation systems in commercial and industrial facilities must comply with national regulations, which are enforced by local authorities. Our engineers select solutions with these requirements in mind.
