Air sander or electric sander? Which is best?

Air sander or electric sander? Many of us will have a preference for the type of sander we like to use, but which is really best for you? 

In this post we share the pros and cons of both air sanders and electric sanders to help you decide which is the most suitable option. 

Cost

Fewer moving parts means that air sanders are generally cheaper than their electric counterparts. This means less maintenance and downtime so you get the job done fast, increasing your productivity and ultimately lowering costs. 

However, while electric sanders tend to be more expensive than air sanders initially, they have lower overall lifetime running costs. This is because running an air compressor is more expensive than running an electric sander.

Safety

Air sanders are safer than electric sanders as you can use them safely in difficult or challenging environments. These are situations that would be hazardous to use electrical tools in.

Air sanders can also be more resistant to elements such as dust, heat and water. These elements can cause electrical tools to deteriorate causing premature tool failure.

Speed

You do get slightly more speed with an air sander than with an electric sander. For example, the Mirka PROS (Air Sander) runs up to 12000rpm compared to 10000rpm on the DEROS (Electric Sander). Having said that, fluctuations in airflow will affect the speed of the machine during use. With electric, the power is consistent so you get an even speed throughout.

Weight

With fewer working components, air sanders are slightly lighter – although remember you need the compressor for them to work. A PROS (Air sander) weighs 0.93kg compared to 1kg for a DEROS (electric).

Sound

The air supply running through the machine makes air sanders a little louder at around 75 decibels compared to 71 decibels for an electric sander.

Lifespan

Air sanders have fewer components to go wrong although both types of sander are extremely durable. However, maintaining the backing pad and keeping them well serviced will always extend the life.  Air and electric last about the same time and remember they will need servicing.

Dust collection

You can connect both air and electric sanders to a dust extractor to give you dust free sanding.

Versatility

Electric sanders can be used anywhere there is a power source. Air sanders are most commonly found in large workshops that already have an air line installed, so it’s a matter of plug in and go. For example, a painter who works in different locations everyday will probably use an electric sander, whereas a cabinet or furniture maker based in a workshop would have the option of both.

You can also adjust the pressure of your air tools from high-pressure blasts to low-powered speed making air sanders suitable for a wide range of applications and uses. 

So, to summarise:

Air sanders

Pros: 

• Versatile as you can take them anywhere even where there is no power
• Safe – use in a range of hazardous conditions
• Cost effective
• Light weight
• Fewer components give them a long lifespan
• Powerful

Cons:

• Can be loud
• Air fluctuations affect the speed of the machine during use
• Need a compressor to work

Electric sanders

Pros:

• Low overall running costs
• Consistent power output throughout use
• Quieter than air sanders

Cons:

• Susceptible to dust, heat and water
• More expensive initial outlay
• Not suitable for areas with moisture, conductive or flammable materials
