Flat oval and spiral duct fittings are fast gaining popularity in the HVAC industry due to various reasons related to their structural and aesthetic value. HVAC is an essential feature inside any building, which is why it’s important to have correct fabrication and design, subsequently contributing to the building’s aesthetic and energy efficiency.
Spiral ducts can give areas a chic look, and be placed in everything from restaurants to residential properties. However, many people still wonder whether these contemporary spiral ducts are just for visual boosts or if they have some functional advantages.
Flat Oval Duct Fabrication
When a designer is designing ductwork, some factors like fabrication, performance, acoustics, and economics should be put into consideration.
One of the main benefits of a flat oval duct system is that it allows for longer lengths than the average rectangular ducts. Some oval ducts can even be 12 feet long, unlike rectangular ducts which can only go up to 5 feet long. This factor leads to lesser number of joints, which in turn means less air loss and maximum efficiency. The oval ducts also do not bulge due to air pressure like in other duct shapes.
The extra length of flat oval ducts also makes installation easier. With its pros and cons, the benefits of oval duct immensely outweigh its disadvantages.
Let’s take a look at some of the main benefits of oval duct systems:
Protects against air leakage
Air leakage is a common and significant problem that occurs at ducts joints. It often leads system inefficiency and excessive energy loss in your HVAC system. Oval ducts are well sealed to keep air intact and avoid leakage, unlike rectangular ducts which need reinforcement for efficient airflow.
Lowers the pressure of air leaving the duct
Oval ductwork usually has a consistent internal pressure which enables air to flow smoothly. This, in turn, allows maximum ventilation inside the duct.
Minimizes additional maintenance costs
Air leakage is one catastrophe that increases the maintenance cost of ducts when it comes to heating, cooling, and filtering. Since oval ducts have a tight air system which has zero air leakage, maintenance costs are minimized.
Clean air quality
Air leakage can seriously compromise the quality of indoor air. Poor air quality can affect users of the building by making them sick. With spiral ducts, you will experience much cleaner air since the airtight ducts don’t allow any air inside or outside them. This means you don’t have to freshen your indoor air frequently.
Equal pressure
Rectangular ducts often have a difference in pressure inside the ducts, which means some noise. Spiral ducting has constant and equal air pressure due to its design. Additionally, there are no airflow interruptions, making it much quieter.
Easy cleaning
Having your building’s ductwork inspection and frequent cleaning is always a brilliant idea to keep the HVAC system energy-efficient as well as providing fresh air throughout the area. As much as cleaning may be a choice, it is also a requirement for your overall wellbeing.
There are various cost-efficient and effective cleaning methods for these spiral ducts. Furthermore, these services are widely available and approved by the authorities in charge.
Minimal space
As a building owner, you probably understand the frustration that comes with incorrect measurements and the need for additional space. Rectangular ducts often need lots of space for connectors and sometimes reinforcements at the joints.
Spiral ducts, on the other hand, are seamless and take up very little space. This is ideal even for small buildings with minimal space. Research shows that when installing spiral ductwork, you can save space of up to 3 inches compared to rectangular ductwork system.
From the above benefits of flat oval duct over the rectangular duct system, we can see why oval and spiral ducts are ranking among the top products in the HVAC market. They are not only stylish but have numerous industrial benefits that can save you quite a lot – contact DC Duct and Sheet Metal right away.
