Ventilating a building refers to replacing the stale or foul air in a room with clean and fresh air. The ventilation system is a must-have for industries and essential for many different applications, which send the undesired air out, and let the fresh air in.

The key variables that you should look into when choosing the right industrial exhaust fan is the fan model, as well as, the air volume flow rate (CFM). Apart from the model and flow rate, you should also look into the resistance to airflow (such as, static pressure or SP) and sound that is produced by the fan.

There are 4 parameters that need to be determined when choosing the right exhaust fan for your industrial company in Malaysia.

1. Exhaust fans perform the basic function of moving warm air from one space to another. But these days, there is a great diversity of fan applications that has let manufacturers to develop a variety of exhaust fan models. Each fan model comes with its own set of benefits for certain applications and provides the most economical and efficient means of performing the air movement function.

2. Choose between direct drive versus belt drive. The former is comparatively more economical for low volume and low static pressure. Direct Drive fans require little maintenance and most of them can be used with speed control to adjust their CFM. Belt drive fans are more suited for air volumes that are above 2,000 CFM or have static pressures above 0.50.

3. Choose between a propeller versus centrifugal fan. The former provides an economical method to move considerably large air volumes (around 5,000+ CFM) at low static pressures (0.50” or less). Propellers are mounted in the air stream that limits applications to relatively cleaner air at maximum temperatures of 40ºc. Centrifugal fans are comparatively more efficient with higher static pressures and are also quieter than propeller fans. They are designed with motors that can be mounted out of the air stream that can ventilate contaminated and high temperature air.

4. Fan models are typically designed to be mounted at three locations: either in a wall, on a roof, or in a duct. Whatever the location, the components of the fan components do not change. Only the housing of the changes to make installation as easy as possible. Determining the best location for the exhaust fan depends on the desired pattern of the airflow, as well as, the physical characteristics of the building.

If you want an exhaust fan to perform a particular function in your industry, but it is not clear which fan model you should use or even what flow rate is needed. If that is the case, you need to choose a fan that is suitable to your needs. Industrial exhaust fan by Yarker Industries is designed using the negative pressure principle that quickly removes heat, odors and pollution and greatly improve the indoor environment of any room.
