Intakes, exhausts, cowls - key elements of ventilation

Intakes, exhausts and cowls are essential components of every ventilation system.   They play a key role in ensuring proper air circulation. Our experience shows that the right selection of these elements has a huge impact on the efficiency of the entire installation. At Onninen, we offer a wide selection of products from renowned brands. Our range includes solutions for various applications and installation conditions.

We often come across questions about the differences between the various types of intake and exhaust vents. So let us explain that intake vents are used to draw in fresh air from outside. Exhaust vents, on the other hand, discharge stale air outside the building. Caps, on the other hand, are mounted at the ends of ventilation ducts. Their task is to protect against precipitation and wind.

Types of intakes and dischargers available in the Onninen offer

Our range includes various models of intake and discharge vents. We offer, among others:

• Metal wall intakes in sizes from fi160 to fi315
• Flat and convex intakes
• Wall air intakes with safety mesh
• Metal wall outlets in sizes from fi160 to fi315

We especially recommend Heatpex brand products, such as the AN 125 HEATPEX ARIA ADURO convex air intake.   This solution works perfectly in modern ventilation systems. Our experience shows that customers appreciate them for their high quality of workmanship and aesthetic appearance.

It is worth paying attention to the Kermi brand wall air outlets/vents. They are made of aluminum and available in elegant black. They work great in buildings with modern architecture. Their design ensures optimal air flow with minimal resistance.

How to choose the right intakes, exhausts and caps?

Choosing the right ventilation elements is a key issue. In our daily practice, we see how important it is to approach each project individually. When selecting air intakes and exhausts, several important factors should be considered:

• Ventilation system efficiency
• Location and orientation of the building
• Weather conditions in a given region
• Aesthetic and architectural requirements

The size of the air intake and exhaust vents should be adapted to the cross-section of the ventilation ducts.   Too small an element can cause increased flow resistance. Too large an element will not provide the appropriate air velocity. At Onninen we offer expert advice in this area. Our specialists will help you choose the optimal solutions for your specific needs.

Recently, we used the Awenta air intake and exhaust system in a project for a large office building. The client appreciated their high resistance to weather conditions. These elements proved to be excellent in the demanding urban environment. They ensured effective air exchange while maintaining the aesthetics of the facade.

In the case of office reorganization, we most often recommend the use of adjustable caps. They allow easy adjustment of ventilation intensity to the changing layout of the rooms. Our own brands, such as Onnline or FXA, offer a wide selection of such solutions.

Innovations in the field of intakes, dischargers and caps

The ventilation industry is constantly developing, and with it, air intakes, exhaust vents and cowls are evolving.   At Onninen, we follow the latest trends and regularly expand our offer. Elements with built-in air filters are becoming increasingly popular. They allow for preliminary air purification already at the stage of its intake.

Another interesting solution is intakes and exhausts with flow regulation. They allow for automatic adjustment of ventilation intensity to current needs. Such systems work particularly well in buildings with variable loads, such as shopping centers or sports facilities.

Our offer also includes chimney caps with built-in fans. This is an ideal solution for improving the draft in existing installations. They work great in older buildings, where traditional gravity ventilation is sometimes insufficient.

Our experience shows that more and more customers are asking about energy-saving solutions. That is why we recommend heat recovery air intakes and exhausts. They allow for a significant reduction in energy losses related to ventilation. This is particularly important in the context of rising heating costs.

It is worth paying attention to the innovative materials used in the production of intakes and discharge vents.   More and more often, you can find elements made of plastics with high corrosion resistance. They are lighter than traditional metal equivalents, which makes assembly easier. At the same time, they maintain high durability and resistance to weather conditions.

At Onninen, we focus on comprehensive solutions. That is why, in addition to the intakes, exhausts and caps themselves, we also offer the necessary assembly accessories. With us, you will find all the elements needed for proper installation, such as flanges, seals and fastening elements.

Our clients often ask about the possibility of personalizing the air intake and exhaust vents. To meet these expectations, we offer elements in various colors and finishes. This allows for a perfect match to the building's facade or individual aesthetic preferences.

At Onninen we attach great importance to the quality of the products we offer.   All of our intakes, exhausts and attachments undergo rigorous testing. This guarantees their reliable operation even in difficult weather conditions. We focus on solutions that will work well in both frosty winters and hot summers.

We invite you to familiarize yourself with the full range of intakes, discharges and caps available at Onninen. Our consultants will be happy to help you choose the optimal solutions for your project. We guarantee professional support at every stage of implementation, from planning to assembly and operation.
