  • Q:

    We recently got a vacuum pump from you guys. The model is MZ 2C NT. I wonder if I could use this vacuum regulator (0-30") for this pump. Thanks in advance

    • STAFF EXPERT

      A:

      If the port size of the vacuum pump is 1/4" NPT(F), then you are able to use this regulator in conjunction with the pump.

  • Q:

    I see only one exit to the image, is what this regulator can be used to suck by an input and return the vacuum pressure regulated in the other input?
    Asked on 9/21/2015 by Elodie from Sherbrooke, CA

    1 answer

    • STAFF EXPERT

      A:

      The input to the unit is in front of the gauge and the exit or piece that would hook up to the vacuum pump is in on the left side of the gauge. This would be facing behind in the picture.

      Answered on 9/22/2015 by Katie from Technical Support

    The bleed port makes a buzzing noise between 5 and 25 inches of mercury. Is this normal?
    Asked on 6/11/2015 by B

    1 answer

    • STAFF EXPERT

      A:

      The port should be pretty silent. If you are still having difficulties, please contact us directly.

  • Q:

    Can I use this regulator with any vacuum pump? i.e. does it matter how many CFM and inches of Hg my vacuum pump can pull?
    Asked on 4/24/2015 by Anonymous

    1 answer

    • STAFF EXPERT

      A:

      This regulator is designed for the 07061-21 and -22 pumps. It has a 1/4" NPT connection and can be used on other vacuum pumps. The limitations will be 2-27 "Hg and a max of 5 cfm.

  • Q:

    What is the accuracy of the gauge? And is there a vacuum pump that would be compatible with this regulator?
    Asked on 4/24/2014 by DN

    1 answer

    • STAFF EXPERT

      A:

      This gauge has a tolerance of +/- 3%. It can work with a variety of vacuum pumps, but it is advertised to work with 07061-21 and 07061-22.

      This regulator is rated for a maximum flow of 2 cfm. Please have a look at the 98250-00 as an alternative.

It works...after I fixed it. Bleed valve was backwards.

    Comments about None Vacuum Regulator, 0 to 30" Hg, 2 cfm Max Capacity:

    This device simply bleeds in air to reduce vacuum. The regulator did not work on arrival. The factory assembled the bleed valve backwards. The spring goes in first, then the ball bearing. The ball bearing seals against the end of the adjustment knob inside the regulator body.
    After fixing it, it worked fine.
    The ports are not labeled. It does not matter which one is in or out.

      Comments about None Vacuum Regulator, 0 to 30" Hg, 2 cfm Max Capacity:

      Used to control vacuum level in small vessel. Source of vacuum is a 2 cfm vacuum pump. Works perfectly. There is no flow except for the bleed. the output is dead-ended. If a larger pump is used you might have ot add a restrictor in the pump line to limit wasted vacuum capacity. In this application the regulator works perfectly.

        I'm in a new building, with an unregulated vacuum system. I needed a regulator I could trust to control the vacuum on my desicator for my processes. This valve perfectly suits my needs.

          Comments about None Vacuum Regulator, 0 to 30" Hg, 2 cfm Max Capacity:

          I use this with a Buchi V700 pump on a rotary evaporator. It works very well to maintain a given pressure for controlled evaporation, and requires minimal adjustment once evaporation begins.

          This is an inexpensive device that works well for regulating pressure on a rotavap.

            I use it with a rotary evaporator, spinning down vicous liquids which are prone to bump easily. The regulator lets me bring the vacuum right to the edge and hold it.
