Mining & Industrial Fan Questions & Answers

Q&A on mining and industrial fans – types and application scenarios.

Q

What does a booster fan do?

A booster fan is a fan that helps the main ventilation fan by increasing airflow in difficult sections of the system. Instead of replacing the main fan, it works in series with it, adding extra pressu
Q

What is the working principle of a fan?

The working principle of a fan is to convert mechanical energy from a rotating shaft into increased air pressure and velocity, creating a continuous flow of air. Whether the fan is a small desk unit o
Q

How does axial flow work?

To understand how axial flow works, imagine air moving in a straight line through a pipe or tunnel, parallel to the shaft of a rotating fan. In an axial flow fan, the blades are shaped like small wing
Q

How long do fan bearings last?

There is no single fixed number for how long fan bearings last. Bearing life in an industrial or mining fan depends on the mechanical load, speed, alignment, lubrication, vibration and the environment
Q

Which is better centrifugal fan or axial fan?

When people ask which is better, a centrifugal fan or an axial fan, the honest answer is: it depends entirely on the job. Both fan types are essential in mining and industrial ventilation, but each ha
Q

What is an upblast fan?

An upblast fan is a type of exhaust fan that discharges air vertically upward above the roof line. It is usually mounted on a roof curb and designed so that contaminated air, heat, fumes or grease are
Q

What is the difference between radial flow and axial flow fans?

The key difference between radial flow and axial flow fans is the direction in which air moves relative to the fan shaft. This difference in flow direction leads to different pressure capabilities, ef
Q

How to decide on fan size?

Deciding on fan size always begins with the ventilation duty, not the catalogue. To select the right size fan for an industrial plant, tunnel or mine, you must know how much air you need to move and w
Q

What is the difference between cross flow fan and axial fan?

The main difference between a cross flow fan and an axial fan lies in how air moves through the fan and the shape of the impeller. These differences affect the pressure range, noise characteristics an
Q

How to draw a fan curve?

Drawing a fan curve means turning fan performance data into a graph that shows how airflow and pressure are related at a given speed. Fan curves are a basic tool in industrial and mining ventilation d
Q

What is the maximum pressure of axial fan?

There is no single fixed value for the maximum pressure of an axial fan, because pressure capability depends on blade design, diameter, speed and the presence of inlet cones, diffusers and guide vanes
Q

Is 1500 RPM good for a fan?

1500 RPM can be a perfectly good speed for a fan, but the number alone does not tell you if the fan is correctly selected. The suitability of 1500 RPM depends on the fan diameter, type, duty point and
Q

What is the purpose of the axial flow fan?

The main purpose of an axial flow fan is to move large volumes of air efficiently in a straight line, parallel to the fan shaft. Instead of throwing air radially outward like a centrifugal fan, an axi
Q

Is 1000 RPM good?

Whether 1000 RPM is “good” for a fan depends entirely on the fan’s size, design and duty point. Fan performance is a combination of diameter, speed and blade shape. A well-designed large-diameter fan

Q

What is the difference between axial and mixed flow fans?

The main difference between axial and mixed flow fans lies in the way air moves through the impeller and the resulting pressure and efficiency characteristics. An axial fan moves air predominantly par
Q

What is the fan law for RPM?

The fan law for RPM is part of a group of relationships known as the fan affinity laws. These laws describe how airflow, pressure and power change when you alter the rotational speed of a geometricall
Q

What is the difference between centrifugal flow and axial flow?

The essential difference between centrifugal flow and axial flow is the direction in which air moves through the fan and how that affects pressure, efficiency and typical applications. Axial flow mean
Q

Does more RPM mean more speed in fan?

More RPM does mean the fan’s impeller is rotating faster, but whether that is “better” depends on what you are trying to achieve. Higher RPM generally increases airflow and pressure for a given fan, b
Q

Which is better EC fan or axial fan?

Asking which is better, an EC fan or an axial fan can be confusing, because the two terms describe different aspects of a fan. An EC fan is defined by its electronically commutated motor and built in

Q

What is an explosion-proof exhaust fan?

An explosion-proof exhaust fan is a fan designed and certified to operate in hazardous atmospheres without igniting flammable gases, vapours or dust. It performs the same basic job as any exhaust fan—
Q

Which fan blows the most air?

When people ask which fan blows the most air, they are usually thinking about air volume rather than pressure. In terms of pure airflow, the fans that move the most air in real-world ventilation syste
Q

Do I need an explosion proof fan?

You need an explosion-proof fan if the air around the fan may contain flammable gases, vapours or dusts at concentrations where an ignition source could cause an explosion. The decision is not based o
Q

What are the four types of mechanical ventilation?

When we talk about the four types of mechanical ventilation, we are usually referring to how fans and ducts are arranged to move air into and out of a building, plant or underground facility. In most

Q

How do I know if a fan is explosion proof?

The only reliable way to know if a fan is explosion proof is to check its certifications and markings, not just its appearance. Explosion proof fans for hazardous areas are tested and approved by reco
Q

What is a ventilation fan used for?

A ventilation fan is used to move air in a controlled way so that heat, dust, fumes and gases are kept within safe limits. Instead of allowing air to stagnate, a ventilation fan creates a flow path th
Q

What is the function of a PA fan?

A PA fan, or primary air fan, is a specialised combustion air fan used mainly on coal fired boilers to supply and control primary air to the burners. In many power plants and large industrial boilers,
Q

Do air vent fans really work?

Yes, air vent fans really do work—provided they are correctly sized, installed and ducted for the space and the job they are supposed to do. An air vent fan is simply a ventilation fan used to exhaust
Q

What is an ID & FD fan?

ID and FD fans are the two main draft fans that move air and flue gas through boilers and many industrial furnaces. FD stands for forced draft fan, and ID stands for induced draft fan. Together they f
Q

What are the benefits of a ventilation fan?

Ventilation fans provide many important benefits in buildings, factories, tunnels and underground mines. By actively moving air, they help control contaminants, temperature, humidity and pressure, all
Q

What is the function of the fan in the air?

The basic function of a fan in the air is to create controlled airflow and pressure so that air can be moved, distributed and exchanged where it is needed. Whether the fan is a small unit in a room or
