Reasons Why Remote Blowers are Better Than Built-in Blowers

Posted by Everest Blowers on December 28th, 2017

In industrial settings, blowers are used to disperse air and gases within and outside the system. They generally are used as a medium of air circulation for exhaust, personnel or material handling. In some of the industrial and commercial building, they are also used as a coolant because they are not too costly when compared to air conditioning. They can solve various other problems such as ventilation, dampness, stratification etc. But mostly these are used for industrial purpose where a high static pressure is required.

The industrial blowers can broadly be categorized into following types: 

• Axial blowers: they designed in such form to circulates air flow parallel to blower blade. Example: tube axial blower.
• Positive displacement: they constitute of multiple co-rotating blades that move air or gases in a controlled manner. Example: Bi-lobe, tri-lobe blowers etc.
• Centrifugal blowers: In such types, blades of the Blower rotate in the perpendicular to air flow. Example: radial blower
• Crossflow blowers: They draw air and gases from radial inlet of the rotating vane and expel air and gases to the opposite side through an outlet. Such type of blower is generally used where space is small and desire concentrated steam of air.

These are an integral part of any high-pressure application system. Usually, people are in the perception that blowers are pre-attached to the system. A built-in blower is usually comes attached to the system itself. Whereas, remote ones are not pre-installed part of the system. They are added externally to the system to provide numerous functions in order to enhance the overall capability of the system. It is always advisable to have a remote blower installed rather than be completely reliant on the inbuilt because of the following reasons:

1. They are a lot safer when compare to inbuilt blower: A remote one is a fail-safe because in a scenario where there is a leakage in the duct during operation, at any point, the duct can be kept under lower pressure and immediate repairing can happen without disturbing the overall system performance. But, if the same scenario existed where there was an inbuilt blower, the entire system needs to be shut down before getting the fault fixed. This could be more hazardous if the system produces any harmful chemicals.

2. An inbuilt blower is not one size that fits all: Every blower can operate under fixed circumstances. The mechanical system has to fit itself for the inbuilt blower to function properly and requires a manual control damper to add resistance to the functionality. In such cases, external blowers are better as they can leverage the performance by leveraging the operating condition depending on the system.                                                                            

3. Inbuilt blowers are nosier: These inbuilt parts are louder, and the issue can arise due to various reasons during the operation of the system. Hence, it is highly recommended to use a remote blower as they don't completely rely on the system and a silencer can be added to eliminate or reduce the noise.
