While choosing a blower impeller, energy efficiency is one of the most important performance specifications. Today many industries are using these fans to keep the room ventilated properly. Manufacturers have continued to redesign the blowers to meet the energy consumption requirements. The introduction of new technologies has led to the more energy-efficient impeller. These have increased functional and performance.
With all these advancements and new products to choose from it has become very important to understand the application that benefits most from the blowers. This will help you to choose better products which meet the cooling solution of your application.
The blowers that you get today have space-saving designs, maintenance-free operation and simplified installation and mounting. The blowers produce a high volume of air which is directed or concentrated to deliver better industrial and commercial air movement. These blowers combined with small size and high efficiency to significantly lower the intrinsic heat inside the system. The low profile designs of the blowers provide you with excellent airflow over the motor. This also helps ensure low internal operating temperature and substantial energy savings.
The blowers are generally used for the applications with back pressure or higher impedance. This also includes freezing and refrigeration equipment, cabinets, ovens and enclosures.
Types Of Blowers
Mainly you will get three types of blowers are available in the market. These are positive displacement, centrifugal and cross-axial. The centrifugal blowers have amazing features like long life, high efficiency and deliver you with high aerodynamic efficiency.
The centrifugal blowers have compact designs because the external rotor motor enables the blowers to be mounted directly to the motor without any kind of external driveshaft. Air is drawn in parallel to the drive axis and then gets deflected at 90 degrees by the rotation. These blowers provide low airflow at the high-pressure system compared to the axial fans.
The maximum noise levels are specified in the acoustic standards of noise for electrical and electronic devices. The noise levels are understandably the most rigorous for the units used inside. However, noise or loudness is human perception. The volume of noise is generally the subjective term which tries to describe the overall strength of the perception of sound through our sense of hearing. The dB levels of blowers can be defined as:
• 3dB: Barely noticeable
• 5dB- noticeable
• 10dB- twice the volume
The noise is generally caused due to numerous factors which include the blower speed, vortex, load, turbulence, shedding and vibration. You can choose to minimise the noise by reducing the system impendence, the size of the fan and the speed of the application, reducing the airflow disturbances, optimum installation location and consistent temperature.
These were some of the basic facts about the blowers available in the market. These points will also help you to choose better blower for your use from the best blower impeller manufacturer and supplier in India. There are plenty of models available in the market which are good for your use. You can choose the type based on your application and need and can also reduce the level of noise accordingly.
