Is the Noise of an Air Suspension Blower Loud?

The noise of an air suspension blower is actually not loud at all. In fact low noise is one of its biggest advantages.

Compared with the sharp mechanical noise produced by traditional Roots blowers air suspension blowers operate much more quietly. After many companies upgrade their equipment they no longer need to build separate soundproof rooms. This not only lowers construction costs but also saves a large amount of money on sound insulation materials.

Below we will explain the noise level working principle and real application value of air suspension blowers so you can better understand their quiet operation advantages.

How Quiet Is an Air Suspension Blower?

Under normal conditions the noise level of an air suspension blower can usually be controlled below 80 decibels at a distance of 1 meter from the equipment. This is a major improvement compared with traditional blowers.

Traditional Roots blowers usually produce noise levels between 110 and 120 decibels. The sound is extremely harsh similar to an airplane taking off or a heavy truck running. Long term exposure not only affects communication but may also damage hearing. Because of this most factories need additional soundproof covers or dedicated soundproof rooms.

An air suspension blower sounds more like loud conversation or a vacuum cleaner. Most of the sound comes from gentle airflow. In most cases it can be installed directly inside the workshop without additional soundproof treatment.

Noise Reduction Results Are More Obvious After Equipment Upgrades

Many companies have experienced a significant drop in noise after replacing old equipment.

For example a waste incineration power plant in Zhuzhou replaced traditional Roots blowers with air suspension blowers. Indoor noise levels dropped from 114 decibels to 84 decibels while outdoor noise dropped from 95.6 decibels to 52.2 decibels effectively solving nearby noise complaints.

Another cement plant in Linyi also reduced the noise outside the blower room to below 80 decibels after the upgrade greatly reducing complaints from nearby residents.

Why Are Air Suspension Blowers So Quiet?

The low noise performance of air suspension blowers mainly comes from their special structural design.

No Mechanical Contact

This is the most important reason.

Air suspension blowers use air bearing technology. During high speed operation the rotor floats in the air with almost no physical contact with the bearing.

This greatly reduces the mechanical friction and gear meshing noise commonly found in traditional blowers.

Very Low Vibration

Traditional blowers usually generate strong vibration and many low frequency noises actually come from vibration.

Because there is no mechanical contact air suspension blowers run much more smoothly. Equipment vibration is almost negligible which naturally reduces noise levels.

Simpler Direct Drive Structure

Air suspension blowers usually use a direct connection between the motor and impeller without gearboxes or couplings.

This not only reduces transmission loss but also lowers additional noise caused by transmission components.

Built In High Efficiency Silencing System

Many modern air suspension blowers are equipped with high efficiency silencers at the air inlet and outlet.

These systems further reduce aerodynamic noise created by airflow making the operating environment even quieter.

What Practical Benefits Can Low Noise Bring to Companies?

For many companies low noise means more than just comfort. It can also directly reduce costs.

Lower Soundproofing Costs

After using air suspension blowers many projects no longer need soundproof rooms or expensive sound insulation materials.

This alone can save tens of thousands or even hundreds of thousands of dollars.

Save Installation Space

The equipment can be installed directly inside the workshop without creating separate enclosed spaces.

This is especially useful for factories with limited production areas.

Easier Environmental Compliance

Many factories face environmental noise inspections.

Because air suspension blowers produce lower noise they are more likely to meet environmental standards and reduce the risk of complaints or fines caused by excessive noise.

Better Working Environment for Employees

A quieter environment makes communication easier and helps reduce hearing damage caused by long term exposure to loud equipment.

Overall the working experience is much better than with traditional blowers.

Conclusion

If you are worried that air suspension blowers may be noisy there is really no need to worry.

Low noise is one of the biggest advantages of air suspension blowers. Compared with traditional blowers they operate more quietly produce less vibration and provide a more comfortable working environment.

Today they have become an important choice for many industrial companies carrying out energy saving and noise reduction upgrades and are considered one of the quietest industrial blower solutions available.
