Mining & Industrial Fan Questions & Answers

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

Q

What are the three types of ventilation systems?

In industrial plants and mines, the three main types of ventilation systems are natural ventilation, mechanical ventilation and mixed-mode (hybrid) ventilation. Each system moves air in a different wa
Q

What is the Atkinson resistance?

Atkinson resistance is a practical resistance coefficient used in mine ventilation to describe how much pressure is lost when air flows through an airway. Instead of working directly with friction fac
Q

What is an ATEX fan?

An ATEX fan is an explosion-proof industrial fan that has been designed and certified for use in hazardous areas where explosive gases or dusts may be present. The term “ATEX” comes from European dire
Q

What are the two types of fans?

From an engineering point of view, the two basic types of fans are axial fans and centrifugal fans. Almost every industrial, HVAC and mining ventilation fan belongs to one of these two families or is

Q

What are the three types of mechanical ventilation?

In industrial and mining environments, the three main types of mechanical ventilation are local exhaust ventilation, general (dilution) ventilation and mechanical supply or pressurization systems. All
Q

What are the three purposes of ventilation?

The three main purposes of ventilation are to provide fresh air, remove harmful contaminants and control temperature and humidity. These goals apply to offices, factories and, most critically, tunnels
Q

What is a rotating fan called?

When people ask what a rotating fan is called, they may mean two different things. First, almost every fan used in homes, industry and mining is a rotating fan in the sense that it has a rotating impe
Q

What is the rule of thumb for natural ventilation?

There is no single magic formula for natural ventilation, but in practice engineers use several rules of thumb for natural ventilation when designing industrial buildings, workshops and some shallow u
Q

What is a booster fan used for?

A booster fan is used whenever the main ventilation fan alone cannot deliver enough airflow or pressure to a particular part of a system. In industrial plants, tunnels and especially underground mines
Q

How to improve fan speed?

When people ask how to improve fan speed, they usually want more airflow from existing equipment. In industrial and mining ventilation, simply forcing a fan to run faster without engineering review ca
