  1. Air Flow Direction

    Is this marked as having left to right air flow direction when looking at the guage side? If so, can the guage and bracket be moved to the other side to reverse the direction?

    1. The flow can be switch by simply switching the gauge and the backing plate to opposite sides. I followed the directions in the box the first time and works like a charm

      Helpful?

    2. Yes it can, the gauge is easy to swap from side to side, just don't lose the O-rings, and the bracket is under a large nut, so you can loosen it and move the bracket. Had to do that for our installation.

      Helpful?

    3. It has left to right. And yes it can be changed. Great instructions. Easy to switch.

      Helpful?

    4. This Rapid/Air Filter Regulator does come with it's air flow from left to right. The instructions are included to reverse this direction if needed.

      Helpful?

    5. Yes it is marked for air flow from left to right. The instructions are included to reverse this direction if needed. Our layout required it to be reversed. It was easy and it took less than 2 minutes to reverse the air flow direction.

  2. Is the outlet port also 3/4 inch?

    1. 3/4" inlet and 3/4" outlet. use pipe thread sealant and not pipe thread tape.

      Helpful?

    2. Outlet port is also 3/4 inch.

      Helpful?

    3. Yes 3/4 in and 3/4 out!

      Helpful?

    4. Hi Jeff, Yes, the input and output of this regulator are the same size. I used reducer couplings to bring mine down to the 1/4" hose fittings on both sides.

      Helpful?

    5. Yes, the outlet port is also 3/4" NPT.

      Helpful?

  3. Thread size for inlet/outlet ports

    I purchased your average 3/4 inch copper pipe fitting to install in this regulator. Unfortunately, after about 4 full turns it started to get very snug. It was a bear to remove from unit. Anybody have the exact thread size for this filter/regulator?
    Thanks

    1. Npt.

      Helpful?

    2. The inlet and outlet ports are 3/4 National Pipe Thread and screw in differently from either side.

      Helpful?

  4. Is this a self relieving regulator?

    1. No, it is manual.

      Helpful?

    2. This regulator features a manual drain.

  5. What is the CFM spec when wide open?

    1. 300 CFM.

      Helpful?

    2. The max CFM this filter regulator will handle when wide open is 300.

      Helpful?

  6. Is this a Full flow regulator

    Hi, is this unit a full flow regulator or does it reduce the flow of air to regulate?

    1. you can regulate the flow

      Helpful?

    2. This RapiAir filter regulator with gauge is a full flow regulator.

      Helpful?

  7. How many feet from the compressor should these be installed?

    1 answer

    1. Pressure regulators should be placed as close to the tool as possible to avoid any fluctuation in air pressure.

      Helpful?

  8. it appears to have a glass enclosure...can you see the water level?

    1 answer

    1. The water level is visible through clear sections on this gauge.

      Helpful?

  9. can this unit be used with synthetic comp. oil?, also do you have a 1/2 in inlet filter that comes with a metal bowl instead?

    many brands of filters with poly bowls state to not use it with synthetic comp. oil.

    1 answer

    1. This item is capable of operating with synthetic oil. We also carry a filter regulator that is fitted with a metal bowl. Please see my recommendation below for item 159673.

      Helpful?

  10. Can I replace the "embedded pressure gauge" with a larger more accurate gauge? What size and thread is the port?

    1 answer

    1. It is not recommended to remove the pressure gauge that comes with the RapidAir Filter Regulator and by doing so it would void the manufacturers warranty. The RapidAir Filter Regulator features 3/4" NPT ports.
