Essential Quiet Air Compressor Considerations Before Investing in One of Them

Air compressors are equipment that performs various functions when attached to pneumatic machines. They generate more power and torque and tend to last longer because, compared to electric tools, they have fewer moving parts. They vary in terms of applications, capacity, size, and noise production. A quiet air compressor is particularly handy in certain industries, e.g., healthcare, where noise is avoided.

The loudness of sound is measured in decibels, and most industrial air compressors generate between 40 to 90 dB. Generally, they are somewhere around 60 dB. These high decibels may not just cause discomfort to people on the premises but can result in hearing damage and possibly loss. This makes picking a less destructive air compressor important.

The Benefits of a Quiet Air Compressor

There are different categories of people that may find a quiet air compressor handy. Regardless of if you are a heavy-duty mechanic, contractor, or have a serious hobby in technical areas, an air compressor that can satisfy your needs is a great investment. Opting for an ultra-quiet air compressor offers you the following benefits:

  • Clean Air

Clean air is a vital constituent of a healthy life. Unfortunately, most of the air we believe to be clean is, in reality, contaminated by all sorts of impurities. With a silent air compressor, you and the people around you enjoy pure air, minimizing the risk of respiratory issues.

  • No Hearing Difficulties

Exposure to loud noise for extended periods increases your risk of suffering from hearing impairments. Quiet air compressors permit you to work in a conducive environment, free from disturbance. It also means that you and others around you do not need to strain their ears or voices when communicating.

  • Improved Productivity

With a more serene environment, workers can better concentrate on their tasks, leading to improved efficiency. Communication difficulties are minimized, and the workflow is more fluid. The low noise also makes the workplace safer as the risk of self or machine harm reduces in calm surroundings.

What You Need to Know Before Buying a Silent Air Compressor

Picking the best silent air compressor for your business means you have to consider several factors. These include the size of the tank, the decibel level, and the PSI count. You must also note your business capacity and its estimated weekly output. We get into detail about these and more below:

Horsepower

The horsepower rating is a great way to assist you in determining your preferred air compressor size. Unfortunately, many marketing teams from manufacturers exaggerate these ratings to sell more machines. Industrial compressors are usually more accurately rated than the silent variant.

An excellent way to uncover the true horsepower is by checking how much electrical power is needed to run it. An actual 5HP motor will require 24 amps on a 220-volt circuit, while the shams can make do with a regular 15 amp 110-volt circuit that is suited for a 2 HP motor.

Worthy of note is that electric motors and gas engine HPs are rated differently. A 10 HP gas compressor is likely to produce air equivalent to its 5 HP electric counterpart.

Air Pressure (PSI)

Air pressure is typically measured in pounds per square inch (PSI). The majority of air tools need 90 PSI to function properly, but a compressor like this will need a high shut-off pressure. This is why many powerful compressors get to their shut-off pressure in two stages. They first build to 90 PSI and the 175 PSI.

However, since silent air compressors are usually of lower power, they use the single-stage method and shut off between 125 – 135 PSI. Though you may think this is plenty of air pressure, some may kick in at 100 PSI, which may translate to insufficient pressure at the tool.

Air Compressor Size

Air compressor tanks’ size does not matter that much as they do not produce but instead store air. When it comes to air production, the pump and motor size are important because they are directly involved in air supply. However, size usually signifies loudness, smaller ones being quieter.

This is because they are made of energy-efficient components. However, it is far from impossible to get an air compressor that is quiet yet produces enough power as industrial air compressors. You also get to save money when you opt for smaller tank sizes, which makes sense for those who only need it intermittently.

Cubic Feet Per Minute (CFM)

Pneumatic tools need a specific volume of air to run. A compressor produces air volume that is measured in cubic feet per minute (CFM). A compressor could have varying CFM ratings at different pressures. You could find a high rating for displacement CFM derived from the speed and size of a compressor’s pump. This particular figure is not that important since the rating at zero pressure does not account for pump inefficiencies.

The rating you should consider for low noise air compressors is the one at 90 PSI since that is the standard required by most tools. Look for a compressor with 3 – 4 CFM per HP at 90 PSI.
