Not well made, leaks.

I really wanted to like this filter setup, it seemed very well built. It worked for about 2 days, then it started leaking. Turned out the diaphragm popped out of the housing. I was able to fix it, but less than a day later it happened again. I think the machining job was poor and there just wasn't enough clamping pressure to sufficiently hold the diaphragm.When I reached out to support to ask for a replacement part, all they offered was for me to return it and buy another. So don't expect any…

Pros
  • Bought this product to help winterize R.V. and trailer. Works really well!
Cons
  • Limited Compatibility: The NANPU 1/2" NPT Air Dryer System may not fit all air compressor models, thus limiting its usability

Thread of Coupling is BSP, NOT NPT

Mine arrived with the black, Japanese type, quick connect plug missing.The thread of the black, Japanese type, quick connect coupler is BSP, NOT NPT as described (see photo taken with blue BSP Fitting Identification Tool). Note that it practically doesn’t have any gaps along the 19TPI thread gauge. Compare this with the Metalwork 1/4” male BSP to 1/4” male NPT converter (silver nipple). One of the photos doesn’t have a gap (BSP end) while the other photo has an increasing gap (NPT end).The 2…

Pros
  • Max Supply Pressure:145 psi; Operating Pressure: 0-125 psi
Cons
  • Any issues with the pressure regulator or semi-auto drain can cause the system to malfunction, leading to air pressure drops and other undesirable consequences

Ultra Compact and Seems Well Built

Just unpacked this and fitted the pressure gauge to the pressure regulator/primary ( 5 micron ) filtration unit. That is the only assembly required other than attaching it to the compressor. There are no nuts and bolts that come with this unit so you will need to figure out what bolts are required for your particular situation.It is ultra compact and the body seems to be made of die cast metal. The bowls are poly carbonate so you need only clean these with soap and water when necessary. No…

Pros
  • Filter & Regulator Combos
Cons
  • Limited Protection: While the system's 5 & 0.5-micron filtration and water trap separator offer some protection against contaminants, they may not be sufficient for heavy-duty applications

well built: my feedback

well build and works well. the dry sealant they put on the threads needs extra tape to be useful, but the tape is provided so it works! using this on my laser cutter

Pros
  • Compressed Air Treatment
Cons
  • Users may experience a lower flow rate when using this air dryer system, which can lead to reduced productivity

Works well, but pressure gauge was not tightened and caused air leakage

After tightening the pressure gauge, the air leak stopped. Also note that the drain was leaking air, but simply tapping it upwards caused the leak to stop.

Pros
  • Excellent quality, should serve me well.
Cons
  • The unit looks solid but it is crap. I couldn't use it it leaks really bad

Very Happy with this!

I bought this because of the good reviews. This NANPU is working great for me with absolutely no leaks. It was a nice upgrade for my old compressor.

Pros
  • Removes 95% of water.
Cons
  • Started leaking out the diaphragm
