Fan Management

We provide fan movement and management services starting with the
underground fans. This will allow us to position the fans and make sure that they comply to the stipulated standards as well as to ensure there is adequate ventilation in the working areas underground.

Our teams work with a delegated member from the mine who is usually a Ventilation Office/Engineer to schedule relocation of fans. If required, we can also provide a Ventilation Technician to assist the team to enable us to provide a more meaningful service.

Real Time Monitoring/Condition monitoring

Telemetric systems assist to constantly monitor the state and conditions of the fan
and allow the relevant personnel to take action in time. We offer the following:
• Real time monitoring of Temperature, Vibration levels, Static pressure, Power
Quality, Power Failure.
• Monitor main surface fans for Air Quality & Air Pressure; Monitor flammable
gases; Monitor vibration & bearing temperature; Monitor AC Power; AC Power
Failure amongst other aspects.
• Control fans (Switch on and off remotely)

Fan management is important to ensure the smooth functionality of the fan thereby maintaining good and adequate ventilation conditions on both underground and surface. With this we offer the following services:

• Relocation of main fans and provide civil engineering, logistics teams and experts
to perform the tasks.

• With the assistance of our partner network, we also assist with maintenance and repairs of fans to ensure faster turnover and make sure all the fans are functional and in working order on time. This will help smoothen the repair process as well.


Fan Selection

Volumetric Flow Rate

The most basic and obvious piece of information for fan selection is the rate of air flow through the fan. The volumetric flow rate measures the volume of air at the fan inlet over a period of time. We typically calculate and specify the air flow in units of Cubic Meter per Second (m3/s).

Fan Static Pressure

Fan Static Pressure is calculated as the difference between the pressure required at the fan outlet and the pressure at the fan inlet plus velocity pressure. It is measured with a water gauge and commonly reported in inches of water column (wc) or water gauge (wg).

Inlet Air Density

The third piece of information we need for fan selection is inlet air density. We calculate inlet air density using three key factors (the 4th factor has minimal impact on most applications):

  1. Temperature
  2. Elevation of the installation
  3. Fan inlet pressure
  4. Moisture content

Intended Fan Duty

The last piece of information we need to properly advise you on fan selection is what duty you expect your fan to handle. It’s often more than just air that moves through a fan. We need to know what your fan will be dealing with, for example:

  • Clean air
  • Saturated gas
  • Material particles
  • Dirty air

Fan Maintenance & Repair

When you do not take care of your assets, machines, and equipment efficiently. Then your company might end up in a loss, but it can be avoided if equipment maintenance activity is done. The activity can extend equipment life one should definitely do equipment maintenance at a regular interval. If you need assistance in equipment maintenance, we can help you all the way, enquire for a quote.

  1. Preventive maintenance – where “a routine for periodically inspecting” with the goal of “noticing small problems and fixing them before major ones develop”. The main aim of preventive maintenance is to make to next maintenance activity without any breakdown and failures of machines and equipment. It includes activities such as partial or complete servicing at specified periods, oil changes, lubrication, etc.
  2. Predictive maintenance – where maintenance is done in advance which means to solve issues in advance. This activity is more like a precaution to escape.
  3. The main objective of predictive maintenance is to determine the condition of equipment & machines to know when maintenance activity can be done.
  1. Corrective maintenance – executed when any defect or fault occurs in an asset, machine, or equipment. Corrective maintenance restores the equipment depending on the fault. It includes various steps after failed equipment such as diagnosis, cause of failure then ordering replacement part & installing new part then testing functionality and continuation of the process. The corrective maintenance can be divided into two parts:
    1. immediate corrective maintenance – one has to take quick action right after the failure.
    2. deferred corrective maintenance – activity is scheduled for later, there can be many reasons behind it. Such as, replacement parts might not be available, it may take a long time or technicians are required on some other high priority cases.
  2. Routine maintenance – is cleaning, oiling, lubricating, replacing batteries & changing the oil. Routine maintenance activity can take place on a weekly or half month basis. It depends on the equipment work.
  3. Emergency maintenance – to prevent a threat to lives, the property of a company. Emergency maintenance can be applied to keep the facility operational and safe. Emergency maintenance is mostly used in chemical plants, tenant buildings, etc.
