4 Ways To Reduce Noise From Your Compressor

A noisy air compressor can disrupt the workplace, making it harder for people to focus and do their best work. Most often it is caused by the motor, vibration, airflow- or a combination of all three. The good news is that you don’t have to live with this. There are easy and cost-effective methods to quiet your air compressor and reduce noise pollution in your plant.

Here are 4 ways to reduce noise from your compressor:

1. Install an Intake Silencer

A compressed air system’s air intake is one of the most common sources of noise. It’s an open path between the machine’s internal moving parts and the room around it. Pulsating air rushing past valves and filter elements, air turbulence, and resonance can amplify certain frequencies, creating quite a bit of noise.

The answer: install an intake silencer sized to your compressor’s flow rate. Or, consider relocating the intake to a more remote location.

2. Add Vibration Isolation Pads

Direct contact with concrete floors turns the floor into a sounding board. Vibration travels through the floor and structure, and the building amplifies it.

The answer: install vibration isolation pads or mounts under the compressor to keep that energy from turning into a low-frequency hum across your facility.

3. Build An Acoustic Enclosure

Noise from the motor, aired, cooling fan, and intake escape in every direction. Each components adds its own sound, creating a symphony of noise that reverberates throughout your facility.

The answer: build a sound-dampening enclosure or panels that contain the noise while keeping airflow and cooling intact. Use proper ventilation with ducted or baffled silencers to reduce noise
without raising operating temperature.

4. Relocate Your Compressor

Distance is one of the most effective ways to lower decimal exposure in your immediate workspace. Hard, reflective walls bounce sound around, and open floor space carries it to
workstations.

The answer: move your compressor to a dedicated compressor room, or run a dedicated air line with an extended remote intake pip to draw air from a quieter area.

A preventative maintenance plan can help reduce noise from your compressor. This will keep bolts, belt guards, brackets and panels secure to reduce rattling. Bearings and couplings create less noise because they are properly lubricated and aligned. Cooling components stay clear, relieving the fan from working overtime.

Lastly, reducing noise can enhance productivity and protect workers from hearing loss, stress, and fatigue. A quieter facility makes it easier from your team to communicate, stay focused, and
work safely.
