UI Control Knob for PR System One REMstar Series CPAP & BiPAP Machines

$7.49

89 Customer Reviews

This is the small round UI Control Knob (Dial) that sits on top of all PR System One CPAP & BiPAP machines. The knob is used to control the machine's various settings and functions as well as to turn the machine on and off.

The System One UI Control Knob is dark, charcoal gray in color with a silver inlay around the rim. The sides of the knob are ridged to make them easy to grip.

COMPATIBILITY: This Control Knob comes standard with all "60 Series" System One CPAP & BiPAP machines -- REMstar Plus 260, REMstar Pro 460, REMstar Auto 560, BiPAP Pro 660, BiPAP Auto 760, etc. It can also be used to replace the lighter gray Control Knob found on all "50 Series" System One CPAP & BiPAP machines -- REMstar Plus 250, REMstar Pro 450, REMstar Auto 550, BiPAP Pro 650, BiPAP Auto 750, etc.

INSTALLATION: When an old UI Knob is removed or lost a small metal ring from inside of it can sometimes get stuck on your CPAP 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.

UI Control Knob for PR System One REMstar Series

The knob stem on my CPAP machine broke which I believe was due to the fatigue of the plastic. Located a replacement at the DirectHomeMedical.com website and ordered. Promptly received via USPS. Replacement part was accompanied with intructions on how to replace. The instructions were very helpful with replacing this particular component and were needed to simplify.
