Best Air Compressor For Sanding - Our Top 3 RecommendationsSanding is a tedious process that requires a combination of factors:

a reliable air hose, a durable sander and perhaps most importantly, a high function air compressor to provide the ideal pressurized air for a high-level pneumatic performance.

We will review three of the best air compressors suitable for the sanding process to afford users the most comfort and convenience possible in their trial of patience within the workshop.

Primarily, when using a sander, it is important to pick the right air compressor based on the sanding tool needs.

A standard orbital sander is a massive air consumer, requiring an output of around 5-6 cfm at 90 PSI for an ideal pressure flow even when labels tell you otherwise, or a huge pressurized air tank capable of providing the immense quantity of air for your work needs.

With that kept in mind, let us look at the air compressors that match up with the demands of the formidable sanding tools.

Option 1: The California Air Tools 10020C air compressor

The air compressor has an output rate of 5.3 cfm at 90 PSI and 6.4 cfm at 40 PSI, which meets the requirement suitable for sanding needs.

Machine parts offer a low sound level of 70 decibels. The compressor produces the least noise among the three models.

Features

The durable metal-clad compressor provides the option of manual or auto drain systems that users may choose at their convenience and runs at 2 horsepower.

With a massive 10-gallon tank, the duty cycle of the California Air Tools 10020C has the capacity to go for 3000 hours as opposed to the usual 500 plus hours in similar air compressor models. These machines are designed to last, no more nagging repair woes!

Being oil-free in its construct means that the model may be used under any weather conditions without concern over temperature issues (cold starts).

Pros

  • Quiet motor operation, reduced noise pollution, no earplugs required.
  • Ease of movement, the tank is hooked up to a wheel base to provide portability.
  • High performance duty cycle for maximized pressuring needs.
  • Long lasting air pumping lifetime hours.
  • Oil-free, free from weather factors.
  • Easy start valve with low amp requirement.

Cons

  • The manual drain pipes are difficult to access.
  • Noise reduction is minimal, far from the quality assurance of the company.

Why we recommend the California Air Tools 10020C?

Considering that the unit includes a 10-gallon pressurized tank, the attached wheels provide portability uncommon to its size.

Lugging around a mammoth compressor is made easy. A low amp startup also wins our attention, wasting no time in starting up your pressurizing process.

Option 2:  The DeWalt D55146 Air Compressor

DeWalt has been a popular household brand for power tool equipment since 1924. Thus, it does not come as a surprise that it delivers quite a winning solution to sanding needs with its D55146 model.

Features

Air pumping is provided at 5.2cfm at 90 PSI and the machine comes equipped with wheels and handles for portability though the item itself is light. Pneumatic wheels offer quick portability around the workshop if required.

Pros

  • Light weight
  • Compact
  • Provides a good power cfm at 90 PSI for sanding needs.
  • Easy-to-use
  • Extreme portability.

Cons: 

Low capacity (4.5 gallon) tank, which stores little pressurized air at any one time.

Here is why we recommend the DeWalt D55146 Air Compressor

Go for the set if you decide on an air compressor that provides no bulk and offers the pressure required for your sanding needs.

However, pay heed to the limited capacity of the model, which does not give much concession to air storage.

Option 3: The Porter Cable PXCMLC3706056 Air Compressor

The first thing we should get out of the way is the hefty price tag hooked to the item. Bearing in mind that despite its portability, the 60-gallon tank is more suited for industrial needs than the confines of a home workshop. The PXCMLC3706056 costs more than double the price of the two other competing compressors on our list.

Hence to the casual hobbyist, this product may seem a bit of an overkill for their sanding needs.

Features

The model has a strong 3.7 horsepower, that ramps up a 13.4 cfm at 40 PSI and a staggering 11.5 cfm at 90 PSI.

An on/off pressure switch allows ease of use. Included with the superior air compressor is synthetic oil that offers extended usage and product performance.

Pros

  • Superior efficiency (way surpassing the ideal running specs of air pressure compressors that power sanding tools).
  • Large air storage capacity.
  • Excellent customer service available through a toll-free hotline.

Cons

  • Expensive
  • Very heavy, the item is best bolted to the ground to prevent slipping accidents.
  • Requires high power supply to run, estimated at 220 volts.

Why do we recommend the Porter Cable PXCMLC3706056?

The model is certainly a heavy-duty provider of pressurized air pressure for your sanding needs thanks to its massive tank capacity of 60 gallons and impressive cfm output.

You may proceed with your sanding jobs through the hours without fear of your air supply ever running out.

Our Finest Pick

And the winner is… Porter Cable PXCMLC3706056 Air Compressor.

Despite its unwieldy size and exorbitant price, we feel that sanding is serious business and for that, we need the best tools that are available.

The Porter Cable provides all the specs (high horse power, large air storage and great cfm) required to fulfill the high demands of an orbital sander, which is one of the most efficient pneumatic sanding tools for your projects.

However, for users on a lower budget, the other two products in our review are more suitable but prepare to face some trouble with the pressure supply if you opt to use a high-end sanding tool since they generally require high compressor functions.
