This Machine UI Knob is installed on top of all PR SystemOne CPAP/BiPAP machines. The knob turns the machine on and off and can be used to update and review overall machine setttings.

The SystemOne Machine UI Knob is dark, charcoal gray in color with a silver rim on the top. The sides of the knob flare out slightly and are ridged for easy gripping.

Compatibility Information: This Machine UI Knob comes standard with all SystemOne 60 SERIES CPAP/BiPAP machines. It can also be used to replace the lighter gray Machine UI Knob found on all SystemOne 50 SERIES CPAP/BiPAP machines.

Usage Information: When an old UI Knob is removed or lost a small metal ring from inside of it can sometimes get stuck on your CPAP/BiPAP machine's knob post. If that ring is present the new UI Knob will not fit properly onto the post. To fit the new UI Knob properly remove the metal ring, either from the post or from inside the new knob, before inserting the new UI Knob onto the machine's knob post.

    Thank you, CPAP exchange for excellent instructions about removing the old metal ring first, before trying to place the new button. The button fits great.

  • Great Service

    Part arrived on time and fit perfectly. Much better price than I found from other websites. Note: Be sure to read the instructions and look closely for the metal ring that's most likely left from the old knob. If you don't remove the old ring you won't get the new knob on.

  • Quick and easy. Great customer service

    I ordered the part by Googling for it. This was the least expensive. When I received the part (not too long), it would not fit. So, I emailed customer service. They got back to me right away and instructed me on the proper installation. Works great! Thanks!!

  • Heads up

    55

    The knob works great. It’s perfect, but they should probably include some instructions. Normally you would think just slip the knob in place. BUT NO. I thought I had purchased the wrong knob, because we couldn’t get the knob on. After doing research online, we realized there is a small metal ring to be removed from the machine prior to installing the new knob. Once that was removed, the knob slid right into place. Good Luck.

    I needed a truly random item - a CPAP machine knob. They had it for a reasonable price, including shipping. Recommended.

  • Best Cost by far

    55

    I needed a replacement controls knob and saw prices in the $25 - $30, which was unbelievable. This was under 25% of that cost. Arrived quickly and was a perfect fit. Buy with confidence.

  • Perfect fit

    55

    It fits perfectly. As others mentioned, I had to remove a sleeve that was left on the stem that you fit the knob onto. It is easily pried up with something strong and thin. Price is a bit high for a knob, but it was still the best price I found. The free shipping was also a bonus.

  • Right knob!

    55

    I had dropped my CPAP packing it into a suitcase on a trip. I didn't recognize that the knob was missing until I got home. Looked online and found this company and the correct knob. Had to ask how to know which series machine I had and was able to resolve the question with the online assistant before ordering. Then when the knob came and had the clamping band in the knob, I needed assurance that I could force it out to fit on the post on the machine. Got the needed info within one day. It is all good! Thank you.

    CXC Notes: Thank you for your purchase and for leaving us your feedback. This comment on the replacement knob has been made before and we've found the following to be helpful: -When replacing your control knob there is often a small silver ring left behind on the post from the original knob fitting -This silver ring impedes the new knob from fitting securely as it directly restricts the new knob's silver fastening from attaching onto the post -Using your fingernails or a pair of tweezers to slide off and remove this metal ring will allow the new knob to fit We'd be happy to provide further troubleshooting on this matter if you still encounter difficulties. We hope this helps and that you have a wonderful day!

    Came one day early. As a previous review stated a metal ring from the old knob had to be removed first. Perfect fit for my cpap machine.

    It did not fit machine, even tho it was supposed to fit. It would have cost too much to return.

    CXC Notes: The PR SystemOne Series Knob will fit all SystemOne 50 and 60 series machines. If you're having problems using it you might review the following from our site: When an old UI Knob is removed or lost a small metal ring from inside of it can sometimes get stuck on your CPAP/BiPAP machine's knob post. If that ring is present the new UI Knob will not fit properly onto the post. To fit the new UI Knob properly remove the metal ring, either from the post or from inside the new knob, before inserting the new UI Knob onto the machine's knob post. -- Hope that helps, Sleep Well!

  • Worked perfectly

    55

    Just what I needed. Would have been helpful to know the is a metal piece inside it, as that had remained on my machine and I first thought the knob didn't fit. Easy fix once I figured that out.
