Installation and Operating:
Preparation
The assembly of all calibration shall meet the maximum flow requirement.
Please clean the port and fitting before installation, it will effectively avoid bring dust to the air path.
Pay attention to direction of air flow and arrow pointing on product body if correct, minding port and thread size if match.
Pressure Adjustment
Pull up the knob of pressure gauge, rotate:
If you do clockwise rotation, pressure will rise steadily.Pressure will down when you rotate counterclockwise.
Stop turning after reaching the required index and lock down the knob,forget this step you may face leakage problem.
Dial Reading
Make sure that the pressure gauge is tightly installed on the main body, and pay attention to whether the reading rises and falls smoothly while adjusting pressure.
Drainage
Drainage column will automatic excrete if there is no pressure,and it will close during the air flow passing. When the water level is beyond upper limit, drainage is necessary, otherwise that will cause poor dehumidification.

I use this for an added level of protection and control of air delivery for my laser cleaner.

Gauge is small; I prefer one larger for a quick, more accurate reading of pressure. Housing appears to be made of some metal alloy; could be aluminum; but the size and wall thicknesses do not lead me to think it can withstand a significant amount of torque, in other words it appears to be fragile. It should be mounted in a protected place to prevent being fractured. I suppose I like brass or steel housings for these to be mounted on portable equipment.

Just got my airbrush going today, put this on for a multitude of reasons. Seems to be working as planned. No water making it out the end. Like the snap-lock on the pressure regulator, feels kinda cheap, but it's not really a wear part. Happy so far.

I purchased two NANPU ARF4000 for my new air system. One had a leak and I returned for an exact replacement. The purchase and return/exchange process went very smooth, with no problems. I'm very happy with the regulator/filter. It's made well and appears to be accurate. I would purchase this item again and recommend the seller.

We received the filter regulator combo and the port on the bottom was broken when we opened it. No box damage. I contacted the company with pictures. They responded that day and had a new one shipped out ASAP. Great experience with customer service. We already have a 1/4" version from this company and like it, so when we needed a larger size for a shop compressor, we looked at their offerings first. Everything works as expected on both versions and they have given us no trouble.

Ordered two units thinking the first one was a one off issue. Second one has same exact issue. The pressure gauge does not have a long enough nipple to allow the gauge to thread in and seal before the gauge body bottoms out on the regulator body. This allows for a leak.

Will not let more than 120 psi through despite adjustment. Tried to take a Honda crank bolt out with my impact couldn't do it at first had to bypass this unit then 150 psi straight from compressor allowed my impact to remove bolt no issues. It's rather restrictive. I'd only use it with a very light duty set up. ended up putting a ball valve on it to have a bypass when I need more juice.
