What Size Air Compressor for Raptor Liner? - Detailed Guide

When it comes to applying Raptor Liner, a popular spray-on bed liner for trucks and other vehicles, choosing the right air compressor is essential to achieve a smooth as well as consistent finish.

The size of the air compressor will depend on several factors such as the recommended air pressure for this specific product you are using, the size of the nozzle you are using, and the size of the project you are undertaking.

In this article, I will discuss what size air compressor is suitable for Raptor Liner along with other important considerations you need to know. So without any further ado let's take a look at it.

Understanding Raptor Liner:

Before diving into the specifics of air compressors, it is important to understand what Raptor Liner is and how it works.

Raptor Liner is a spray-on bed liner that is applied to the surface of a truck bed or other vehicle to protect it from scratches, dents, or other forms of damage and it is made of a durable polyurethane material that is resistant to chemicals, UV rays, and corrosion.

To apply Raptor Liner, you will need a spray gun along with an air compressor. The spray gun is attached to the air compressor via a hose and the air compressor provides the air pressure needed to atomize the material and spray it onto the surface evenly.

The air pressure along with nozzle size will determine the thickness and coverage of the Raptor Liner.

Choosing the Right Air Compressor:

When choosing an air compressor for Raptor Liner there are several factors to consider including:

Air Pressure:

The air pressure required for this product can vary depending on the specific product you are using.

Most Raptor Liner products recommend an air pressure of 45-60 PSI for optimal results and it is important to check the manufacturer's recommendations before selecting an air compressor.

Nozzle Size:

The nozzle size of the spray gun you are using will also impact the air compressor you will need. A smaller nozzle size will require less air pressure and volume while a larger nozzle size will require more.

Tank Size:

The tank capacity of an air compressor is important because it determines how much air the compressor can hold and deliver to the spray gun.

A larger tank will provide more consistent air pressure and allow you to work for longer periods without having to stop and refill the tank.

CFM (Cubic Feet Per Minute):

CFM is a measure of the amount of air that an air compressor can deliver per minute. The CFM rating of an air compressor is important because it determines how quickly the tank can be refilled with compressed air.

A higher CFM rating will allow you to work for longer periods without having to stop and wait for the tank to refill.

What Size Air Compressor is Needed for Raptor Liner?

Based on the above factors, a 10-gallon air compressor with a CFM rating of at least 4-8 with a maximum PSI of between 40 to 60 is generally considered suitable for applying Raptor Liner.

This size compressor will provide enough air pressure and volume to atomize the Raptor Liner material and spray it onto the surface evenly without much difficulty.

However, it's important to note that the compressor's CFM rating should be higher than the spray gun's CFM requirement, and if the compressor can't provide enough airflow it will result in inconsistent spray patterns, clogging, and other issues.

Other Considerations:

Aside from all these things, there are a few other considerations to keep in mind when applying Raptor Liner:


The temperature of the environment in which you are applying Raptor Liner can impact the final finish so it is recommended to apply Raptor Liner in temperatures between 60°F to 70°F for the best results.


High humidity can cause this material to dry more slowly which can result in a less smooth finish so try to apply Raptor Liner in low humidity environments and the manufacturer generally recommends a humidity of less than 60%.

Surface Preparation:

Proper surface preparation is critical for achieving a good finish with raptor liner and the surface should be clean, dry, and free of any oil, grease, or other contaminants that could affect the adhesion of the Raptor Liner material.

Personal Protective Equipment:

Applying Raptor Liner can create a lot of overspray and dust so it is important to wear personal protective equipment such as a respirator, safety glasses, and gloves to protect yourself from any potential hazards.

Frequently Asked Questions (FAQ):

Can I use a smaller air compressor for Raptor liner?

While it's possible to use a smaller air compressor for Raptor liner it may result in inconsistent spray patterns and other issues.

What PSI should Raptor liner be?

The PSI (pounds per square inch) at which Raptor liner should be sprayed varies depending on the specific equipment being used but generally falls within the range of 45-60 PSI.

What is the best temperature to apply Raptor liner?

The best temperature to apply the raptor liner is between 60-70°F (15.5-21.1°C).

What type of spray gun is recommended for Raptor liner?

The raptor liner comes with a kit that includes a spray gun that can be used to spray.

Do I need to thin Raptor liner before spraying?

According to the manufacturer the raptor liner does not need to be thinned before spraying.

Can I use a compressor with a lower PSI rating for Raptor liner?

While a compressor with a lower PSI rating may be able to spray raptor liner it's not recommended so it's important to have enough pressure to atomize the material properly as well as to create an even spray pattern.

A compressor with a higher PSI rating will also be able to handle other spray applications in the future making it a worthwhile investment.

Can I use a DIY air compressor for Raptor liner?

It's possible to use a DIY air compressor for a raptor liner but it may not provide enough power and airflow for a consistent application.

It's recommended to invest in a high-quality air compressor with the minimum CFM and tank size requirements for best results.


Choosing the right air compressor is crucial for achieving a smooth as well as consistent finish when applying this product. The size of the air compressor will depend on several factors such as air pressure, nozzle size, and tank capacity, along with CFM and it is also important to consider other factors such as temperature, humidity, surface preparation, and personal protective equipment to make sure it is done properly.

By taking these factors into account and selecting the appropriate air compressor you can achieve a professional-looking finish with Raptor Liner that will protect your vehicle for years to come. If you find this guide helpful then share it and have a nice day.
