## Description

THIS IS A LOW COST SIMPLE OPTION TO REMOVE MOISTURE FROM YOUR AIR LINES ON SINGLE STAGE AIR COMPRESSORS. THIS UNIT HAS A SEMI AUTOMATIC DRAIN THAT ACTS LIKE AN OVERNIGHT DRAIN. WHEN PRESSURE IS APPLIED TO THE BOWL, THE DRAIN WILL HOLD THE MOISTURE CONTENTS UNLESS YOU MANUALLY DISCHARGE IT. WHEN NO PRESSURE IS APPLIED TO THE BOWL, THE DRAIN AUTOMATICALLY OPENS TO RELEASE THE MOISTURE. IF YOU REMOVE THE BOWL FROM THE UNIT AND DO A WATER TEST TO SEE IF HOLDS MOISTURE, THE BOWL WILL LEAK. THAT IS WHAT ITS DESIGNED TO DO. WHEN PRESSURE IS APPLIED, THE BOWL WILL HOLD MOISTURE CONTENTS AND PRESSURE. THE BEST WAY TO SEPARATE AIR AND MOISTURE FROM YOUR COMPRESSED AIR LINES, STARTS WITH YOUR COMPRESSED AIR LINES THEMSELVES. ALWAYS FORCE AIR TO CLIMB VERTICALLY WHILE POOLING LIQUID MOISTURE IS FORCED DOWNWARDS BY GRAVITY. THIS ALLOWS ONLY MOISTURE VAPOR TO REACH YOUR FILTERS AND WILL PROLONG THE LIFE OF YOUR FILTERS AND AIR TOOLS. YOU CAN ALWAYS SEARCH ONLINE " PROPER COMPRESSED AIR LINE INSTALLATIONS" TO GET SOME IDEAS.

## Questions & Answers

**Q: I can blow through my drain too in all positions (order just got here)! Will the drain act differently under air pressure?**
A: Air Flow goes in to filter and goes out. The drain is for water trap. You can manually turn on/off.  Try to turn off and see if that stop the air blow through drain.

**Q: How often does the filter need to be replaced, and does this come with any air hose connectors (male/female quick connects)?**
A: It truly depends on how much you use the item, as far as filter replacement. And no this does not come with quick connects. Usually this filter is put in line with tubing or some other sort of air piping.

**Q: Could i place this on the line coming from the pump,before it goes into the tank,to help reduce water from entering the tank?**
A: I don’t know why that wouldn’t work. I have a sailor Belle air compressor and it has 1” x 3’ copper line between the pump and the tank thus cooling the air. When you cool the air the moisture condensates out of the air and then you could use this to catch it before it goes into the tank. Make sure this trap is installed level like it is pictured.

**Q: How do i install on pex lines w/o a mounting bracket??? no way to mount to wall/ceiling (and i can't attach to tank)**
A: They make fittings that convert pex to 1/2" or 3/8" pipe thread. I don't know how your running pex without supporting it and not having the tube sag or dip down and collect water.

### ⭐⭐⭐⭐ Worth the price if is holds up.
*by B***. on October 9, 2019*

Filter was sturdy enough to handle daily use in place. Purge valve at bottom of filter was adequate but flimsy. Be careful not to strike it with other objects or it may break. Still testing since it is new. Time and use will tell if it can stand up to workload,
