Our Top Air Compressor Filter Dryer Recommendations
An air compressor filter dryer is used to clean your compressor. Having a dryer also means a lesser chance of forming rust. This helps keep your compressor operating in good condition for a long time. Below is a list of some of the best air compressor filter dryers you can get.






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.
A double filter generally cleans better compared to a single filter. This NANPU filter dryer also has a self-relieving pressure regulator for adjusting outlet pressure, so you won’t have to worry about maintaining the right pressure. This makes this air-drying filter system one of the most popular ones on this list.
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.
It has a port size of ⅜ inch, so it will only fit with compressors with the same port size. 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 easy pressure adjustment is mostly present in most of the dryer filters in this list, so you will easily operate them. This feature is common for highly popular filters, and not having it is usually a dealbreaker for some people.
When it comes to drainage, the drainage column automatically excretes when there is no pressure. It also closes when air is flowing. However, you still have to drain it from time to time for proper dehumidification.
Overall, we put the NANPU DFR Air Drying System as the best overall with all the features and downsides in mind. It gives you everything you need for a dryer filter and some extra. Some of the downsides we can find for it is that its size is limited, so you might have trouble fitting it in some compressors.
Pros
