Axial Fans are one of the common types of industrial fans used at the
Fans are used for applications that demand a larger inflow rate at small pressure gain. Over
times, various types of axial fans or axial inflow fans have gained popularity.
fans are one of them. These fans are currently used in a wide range
of operations from
drying to cooling to ventilation and air force for any machine or industrial process. Owing
the distinct advantages gained from their typical construction, these fans have gained
traction. This post discusses everything you may want to know about these fans.
What's a Tube Axial Fan?
Factors of Tube Axial Fan
A tube axial fan is a type of
industrial comprising a fragment type of wheel or a propeller,
which is contained within a spherical tube-like structure. This fan is analogous to a vane
axial addict, another popular axial inflow fanvariant, with the only difference that it has
no uncurling companion vanes. The propellers are organized similarly so that there's a small
gap between the casing and blade, which helps improve the fan effectiveness.
There's a detailed explanation of a many important factors of tube axial fans
These fans are fitted with propellers made of cast aluminum or heavy- duty steel.
Occasionally propellers are also made of stainless steel. All these materials can repel high
temperatures, which makes them a suitable choice for a propeller. The propeller features a
hub to which the blades are welded. These blades are welded precisely at angles ranging from
30 ° to 50 °. Some manufacturers also give customization choices when it comes to angles.
Generally, propellers are balanced statically to insure their smooth operation.
The housing is the structure that hosts the impeller. It also serves as the welded base of
the machine, which supports the axial flow. Among colorful factors, the performance of the
tube fans depends on the design of the impeller and the shape of the casing.
These fans may be equipped with ball comportments or comber type comportments.
A variety of single to three- phase motors are used in these axial fans.
As the name suggests, this is a small door present on the case; it's useful for examinations,
and is substantially used during conservation operations.
Belt or Pulleys
They play a crucial part in the function of belt- driven fans. The belts are generally chosen
grounded on factors similar as the asked performance of the fanor number of machine
Direct or Belt Driven
Generally, the tube axial fans are belt driven or directly connected to the motor. When belt
driven, the propeller is deposited on a separate fan shaft and connected to the motor, which
runs it through sheaves and belts.However, you'll see the impeller placed on the shaft of
the motor, If motor driven. Axial inflow fans of this type are ideal for operations that
demand large air inflow at low pressures.
Numerous manufacturers offer these fans in all sword or aluminum construction.
Types of Tube Axial fans
As said ahead, there are two types of tube axial fans– direct drive tube axial fan and belt
driven tube axial addict.
Direct Drive TubeAxial fans
Direct drive tube axial fans are ideal for operations where effectiveness and quietness are
needed. These fans are equipped with perfection designed and directly balanced aluminum,
spark propellers, which can fluently move air laden with colors and condensable smothers.
Direct drive tube axial fans are used for heat control process, bank or heat junking,
general ventilation as well as process ventilation purposes. The tube axial fans of this
type bear lower conservation than belt driven bones.
Belt Driven Tube Axial fans
As the name suggests, these industrial tube axial fans feature belt drive, which ventilates
the propeller from outside the addict. These fans are regularly used for general and
industrial ventilation operations where they're used to remove polluted air aqueducts or
humidity-laden air aqueducts.
Performance Characteristics of Tube Axial fans
Tube axial fans have typical performance characteristics due to their propellers and
fandesigns. The fansparade high tailwind effectiveness up to 65.
Owing to their durable construction, these fans can repel 4"water
Generally made of durable materials, these fans can fluently repel
up to 600 degrees Fahrenheit.
Advantages of Using Tube Axial fans
Tube fans are preferred over the other axial inflow fansowing to the following advantages
that they offer
These industrial fans are frequently made of accouterments that can repel
high temperatures, erosion, explosive vapors, and so on.
Most tube axial fans have spark resistant construction.
Their strong construction allows them to process high power and pets
compared to centrifugal fans and regular panel suckers.
Tube axial fans are known for their better pressure characteristics
than regular panel fans.
They're designed for ducted operations, so are also known as duct
Belt driven tube axial fans direct drive tube axial fans offer the
inflexibility of positioning.
You can fluently alter their pressure and tailwind characteristics by
taking advantage of positioning inflexibility. Resemblant positioning enables better
tailwind and series positioning helps optimize their pressure characteristics.
Using propellers with a large hub-to-tip rate helps alter its speed
to press characteristics. For example, using the fan with a large hub-to-tip portion
can be made to work at a particular speed against a specific pressure. Also, it can
be made to work at low speed against a specific pressure.
Application Of Tube Axial fans
Tube axial fans are used across diligence and the following are a many common ones Aeration
Paint spray booth exhaust
Cooling electric outfit or sensitive factors
Machine room, process, and general ventilation
Glass drying and glass tempering
Sucking air from polluted air aqueducts
Like any other industrial cooling fans, it is important to source these tube
axial fans from
trusted manufacturers. Owing to their widespread use, these fans are sold by several brands
and Alfa Fans stands tall among them. The company is one of the leading manufacturers of a
industrial fans in India
