What is Aluminum Flexible Duct?
It refers to a type of passage or conduit designed from aluminum material used in heating, ventilation and air conditioning (HVAC) system to deliver and remove air.
In some instances, it is referred to as aluminum flex duct and comes in varying lengths and diameters.
This unit is an integral element in HVAC system since it offers a convenient method to attach supply air outlets to reasonably rigid ductwork.
Aluminum flexible duct
Which Types of Aluminum Flexible Duct are available?
Aluminum flex duct is available in two major types; which include the following;
Insulated– It refers to a type of aluminum flex duct with covered with a specific material as a way of preventing heat loss from the duct system.
It is an essential component since it helps in reducing space heating as well as costs related to cooling energy.
Overall, it plays a vital role in improving indoor comfort, reducing moisture condensation on surfaces.
Non-insulated – It is the design of this component, which does not necessarily require any form of material to cover its surface.
It works effectively when installed in specific areas within a particular building.
It is designed to ensure it offers optimum performance in surfaces installed.
What are the Properties of Aluminum Flexible Duct?
This component is relatively popular in various applications as a result of its wide-ranging inherent features.
It is such properties, which make it highly effective since it enhances the overall quality of the unit.
Some of these intrinsic features include the following;
Lightweight – It is relatively lightweight compared to other units made of different materials, which offer the same solutions.
Definitely, this is advantageous because it enhances convenience, especially when it comes to handling and installation.
Versatile – You can always use aluminum flex duct in various forms of surfaces within a building.
In essence, it is not necessarily designed to be fitted in a specific place.
Instead, you can install it in areas such as ceiling, within walls, and chases, among others.
Durable – The type of material used for manufacturing this component is resilient and can withstand a wide range of punishment.
It thus indicates it can last for as many years as possible as long as there is proper maintenance.

What is the Use of Aluminum Flexible Duct?
Aluminum flexible duct system
Aluminum flexible duct is used in different designs of HVAC systems.
The main purpose of this equipment is to link the heating and cooling system ductwork to the air distribution.
It is then installed in various types of buildings including commercial, residential, and industrial.
Primarily, this equipment is used for conveying air in cooling and heating systems throughout the building.
Secondly, flexible aluminum duct is also used in electric dryers in several households.
In this instance, it helps in and expelling moist air from the clothes.
And since aluminum does not rust, it makes it a perfect choice for dryer system when it comes to enhancing its efficiency.
How much does Aluminum Flexible Duct Cost?
Generally, the price for aluminum flexible duct cost is relatively dependent on quite a number of factors.
First, the specific aluminum alloy used on the equipment determines the amount you pay to acquire this component.
High-grade aluminum alloy is costlier compared to a somewhat inferior alloy.
The other elements, which defines the cost of this component, is whether you are purchasing locally or importing.
Besides, the latter will be a bit expensive since you’ll have to incur cost related to shipping and other duty charges.
Also, the specific design of aluminum flex duct is another determinant of its cost.
If you go for customized design, which is quite apparent, you’ll spend much more compared to purchasing standard designs.
Moreover, the particular supplier you are purchasing this component from also determines its cost.
Some manufacturers often offer better deals depending on the MOQ and other related terms.
Therefore, you need to ensure you compare prices from different suppliers as a way of getting better rates.
So, in other words, there is absolutely no fixed cost for aluminum flexible duct.
What is the Ideal Diameter for Aluminum Flexible Duct?
Varying diameters of aluminum flexible duct
The suitable diameter for aluminum flexible duct is dependent on the size of the equipment.
And this is directly determined by the application of this equipment.
In most instances, you’ll notice some aluminum flexible ducts are designed to regulate air in somewhat large buildings.
Such units will require bigger diameters compared to others, which are engineered for small-scale applications.
The other determining factor for this component is the amount of air it is projected to regulate.
Some are designed to regulate high-pressure air, whereas others are meant for moderate air pressure.
In general, therefore, the actual diameter for this component is determined by its specific size as well as the amount of air pressure.
How Long does Aluminum Flexible Duct Last?
Ideally, aluminum is one of the strongest materials you can ever find around.
It has superior resistance to various environmental, mechanical as well as chemical elements.
In other words, it can withstand a wide range of elements without necessarily degrading nor distorting.
Even so, the general durability of this component is dependent on the specific conditions it is subjected to.
Additionally, it is also based on the maintenance routine undertaken on it on a regular basis.
But in general, if all factors remain constant, aluminum flexible duct can last for as many years of up to about 25 years.
The most important aspect in determining the overall longevity of this component is ensuring you prevent different elements such as leakage among others.
What is the Difference between Aluminum Flexible Duct and Aluminum Metal Duct?
There is a thin line between these two types of units, which you need to understand perfectly since they have great variance.
And knowing the difference is also fundamental because it puts you in position of determining the most suitable one for your specific needs.
In regards to flexibility, aluminum flex duct seems to be better, especially for the prevailing trunk and branch heating and cooling systems.
Of course, it is relatively more flexible and highly versatile.
Aluminum metal duct, on the other hand, is somewhat rigid as a result of the nature of this particular aluminum material.
Even so, it offers high efficiency when it comes to entire air distribution systems.
Aluminum metal duct
When it comes to durability, aluminum metal duct ranks higher than aluminum flex duct.
Of course, the metal duct is sturdier and has more resistance to environmental and mechanical elements compared to flexi duct.
So metal duct is often used to offer more or less permanent solutions to particularly for commercial HVAC system.
Therefore, the former tends to last relatively more than the latter, given it can withstand different harsh and extreme conditions.
In terms of price, metal duct is seemingly more expensive than flexi duct for obvious reasons.
For one, the manufacturing, transportation, and installation cost for aluminum metal duct are quite higher compared to aluminum flex duct.
Hence making it somewhat expensive in general.
Regarding installation and maintenance, the metal duct is seemingly quite complicated and requires high expertise to effectively fix on the surface.
Aluminum flex duct, on the other hand, is somehow simple to install as well as maintaining.
Can you Clean Aluminum Flexible Duct?
Cleaning aluminum flexible duct is one of the best and highly recommended maintenance routines.
It enhances the efficiency, functionality as well as the overall longevity of this equipment.
Some of the fundamental aspects of cleaning this component include the following;
