What Size Air Compressor For Sander?
Sander needs high capacity and heavy-working compressors for which compressor should at least have these features:
- The compressor at least needs 8-9 CFM at a maximum of 90 PSI for sanders and at least 15-18 CFM for the heavy working sander.
- At least having 150-170 PSI with working of 90 PSI max is an ideal compressor for sanders.

How to Select The Best Air Compressor For Sanding?
Portable or Stationary
The portable compressor is best because you can take it with you anywhere; they are transferable because they have handles and wheels. However, if you are professional and do not need to transport a compressor, then a stationary one will be an ideal choice.
CFM of the compressor is a deciding factor, and it tells how much air the compressor is capable of producing. Sanding the car requires a compressor with at least 15-20 CFM, and then it can do sanding efficiently.
The tank size of the compressor tells how much air is available to you while you do the sanding of a car. Sanding of a vehicle required an 8-10 Gallon air tank. If you need a compressor continuously, you need at least a 20-30 Gallon air tank.
Durable air compressors are steel and cast iron-made compressors. Always look for piston pumps, cast iron, and steel-made body compressors. They provide protection and safety.
The PSI of the compressor allows you to use the compressor at maximum pressure. Most of the sanders need a max of 90 PSI. Choose your compressor with at least 120-150 PSI. Never choose a compressor and sander with the same PSI rate.
The lower the RPM, the less noise it will make. Most compressors run on 1680 RPM, which causes less noise and minor wear.
Oil or Oil-Free
Sanding is heavy-duty work, and most heavy-duty compressors are oil-lubricated. However, most of the new compressors are designed oil-free, and they are heavy-duty at the same time. But the oil-lubricated compressor mostly lasts longer. Decide according to your need, and the oil-free compressor needs less maintenance.
Nowadays, most oil-free compressors are designed to be quiet, and they work on less RPM, making them less noisy compressors. The noise of the compressor matters the most when you are going to use it indoors or in a quiet place. Furthermore, while choosing compressors for sandblasting, consider heavy-duty compressors with a maximum noise level of 60-80 dBA.
The duty cycle of the compressor decides how long your compressor will work. It is represented in percentage and mostly has 50%, which means if your compressor has a 1-hour working life, then it will work for 30 minutes and will need to rest for 30 minutes,
Extension Cord And Hose Length
A portable air compressor may not require extension cords since it can be transported anywhere. While for stationary compressors, use extension cords or a long hose. Extension cords usually reduce the efficiency of the compressor.
Always choose a compressor with an affordable price and features. Never opt for the compressor, which has fewer features and has a high price. Always do research and buy for the place where it is available at great prices.
Amazon User Reviews
When you decide to buy a compressor, always do some research for reviews on the compressor. It does not matter where you are purchasing the compressor. You check the reviews and comments of different users and even communicate with them and get the honest and most unfiltered reviews, which are helpful.
What Is Sanding?
Sanding is the process of smoothing and cleaning with sandpaper. It is used on surfaces like metal and wood. In this process, you rub your sandpaper on your wood gently. The raw woods have rough edges, and they have particles that cause hindrance while getting fine wood.
What is sanding done? Sanding is done to remove impurities from the object. Wooden surfaces become dry while coating, and dust and soil particles settle on them. These irregularities cause defective finish and adhesion issues.
What is Pneumatic Sander?
A pneumatic sander is a device that uses compressed air to power drums, belts, and orbital discs. It works by pressing or triggering a button on sanders. It is excellent for removing old paint and rust and smoothing welded joints.
What is Orbital Sander?
It is a tool used for sanding that can smooth rough surfaces of metal, wood, or plastic. The orbital sander can also help remove paint and rust from the surface. Hold the sander by pressing it across the surface.
Why are orbital sanders better? It has flexibility and works great for corners, and it can work on corners efficiently, so it is better for heavy work.
What is a Disc Sander?
A disc sander is a device that has one or more than one circular disks to smooth wood surfaces. It is placed on a circular plate made with abrasive paper, and it is ideal for grain work, shaping, trimming, and rounding corners.
It is the best sander because one can use it for edge working, fitting joints, and truing curves. While sanding holds your object firmly, sand it downward of the disc. Upward sanding can get you in accidents.
What is an Air Belt Sander?
An air belt sander is a device used to give smoothness and contour to the corners of wood, metal, and other materials. It can have interior or exterior corners. Sander is also used for trimming, sanding hard surfaces, rounding, and giving shape.
When looking for a belt sander, measure the width and length of the belt. Its speed of removing materials and dust collection. While using it, avoid using it without an exhaust system or dust collector. Do not put pressure on the moving sander, using only heavy enough stock which stays in its place. Air sander compressor requirements are high CFM and PSI.
Sanding is a great way to clean the surface from any particles, either dust or oil. For sanding, you need a sander with the best capacity compressor. For the best air compressor for sanding, you need to consider the CFM, PSI, HP, and tank size of the compressor.
We’ve reviewed some of the best air compressors for sanding jobs so that you may choose the one according to your requirements.
Sanders for sanding cars are pneumatic, orbital, disc, and air belt. Although all are good, the orbital is ideal for heavy sanding work. Choose according to your requirements and needs.
How much air does a DA sander need?
The minimum air pressure to run a sander you require is 90 PSI. If you use only one machine with a compressor, 90-100 PSI is ideal. The sanders are great for woodwork and metalworking. Dual sanders require 11-13 CFM at 90 PSI.
What size air compressor do I need for sandblasting?
Sandblasters make large and tough jobs of sandblasting easy. They are used for cleaning rust and paint from metals. You’ll need a good compressor with it to get good results. The compressor should be at least 10-20 CFM with 100 PSI for that purpose.
Does tank size matter to air compressors?
Tanks are used to store air 4-6 Gallon air tanks are great if you do not need continuous air for a long time, such as sandblasting and nailing. An oversized pump and a good motor are more important as they produce air.
