Our Top Air Compressor Filter Dryer Recommendations
The NANPU DFR-03 NPT Air Drying System tops the list of the best filter dryers for air compressors. Its high flow rate and powerful supply pressure can keep compressors in good condition.
Many air compressor filter dryers are on the market, making choosing one compatible with your compressor easy. However, you may face a challenge getting one if you know little about them. Therefore, I have compiled a list of the best air filters in the market to help you choose the right one.
Best Air Compressor Filter Dryer Overall: Nanpu DFR-03 Npt Air Drying System
The NANPU DFR-03 NPT Air Drying System is one of the best filter dryers you can get for your air compressor. This double-air filter is made to remove water and other liquids as well as particles from your compressor.
The calibration for this dryer filter follows the maximum flow requirement, and you just need to assemble it properly for use. This air drying system can function as an air filter, lubricator, and regulator, reducing your need for spending on other accessories.
Like Campbell Hausfeld Air Cleaner/Air Dryer, this one has a port size of ⅜ inch, so it will only fit with the same port size compressors. So make sure you check your port size or get an adapter.
The pressure adjustment on this air-drying system is easy to use. Just pull up the knob of the pressure gauge and rotate it clockwise to increase pressure and counterclockwise to decrease. The device has an operating pressure range of 0 to 125 PSI, making it easy to choose the one ideal for your compressor.
The easy pressure adjustment is mostly present in most dryer filters in this list, so you will efficiently operate them. This feature is common for highly popular filters, and not having it is usually a dealbreaker for some people.
This air-drying system has a drainage column automatically excretes when there is no pressure. It also closes when air is flowing. However, you still have to drain it occasionally for proper dehumidification.
Overall, I consider the NANPU DFR Air Drying System the best overall with all the features and downsides in mind. It gives you everything you need for a dryer filter and some extra. One downside is that its size is limited, so you might have trouble fitting it in some compressors.
Pros
- Double filter and self-relieving pressure makes it effective in filtering

Each of them has its own unique features. You just have to pick which is compatible with your air compressor and what applications you plan to use. The NANPU Air Drying System, with its double air filters, ensures the air is highly filtered and contains no dirt.
Material Quality
The quality of the material used affects the product’s durability. Look for metallic materials to ensure the filter lasts longer. If you are working in extreme temperatures, use one that can withstand such temperatures.
The Campbell Hausfeld is your best choice since it’s made of metallic materials and has the best build quality on the list.
Frequently Asked Questions
Do You Need an Air Dryer for My Compressor?
Yes, you need an air dryer for your compressor because they help keep compressors free of moisture and prevent rust from forming. The air dryers do this by condensing water vapor hence compressing the air. This results in a dryer air that minimizes the compressor’s damage.
How Do You Get Moisture Out of Compressed Air?
You can get the moisture out of compressed air by draining the tank. Other methods include water traps, filter regulators, and air dryers. Removing the moisture also ensures the internal parts of your compressor are not damaged, reducing repair costs.
What Is a Non-Cycling Air Dryer?
Non-cycling air dryers have refrigeration compressors. It starts once you turn the dryer on and will continue until it is off. They are sometimes called constant-speed or fixed-speed air dryers because they maintain a continuous operation of the compressor system.
Conclusion
An air compressor filter is one of the versatile devices that helps your compressor work well and last long. Therefore, getting one that is compatible with your air compressor and functions appropriately is ideal. This list has some of the best air compressor filter dyers in the market.
