Product Description

Lower hour (Under 2000 hours) device with a 30 day In-house warranty. As with all our reconditioned CPAP and BIPAP machines, this unit comes with our CL Refurb Certification which ensures that the device has been properly cleaned and tested by a licensed Respiratory Therapist. 


The Respironics Legacy Series BPAP ST/Harmony ST is an Advanced BIPAP which is noted for its quiet blower motor output level, and very low failure rate. Features include Spontaneous (S - standard BIPAP) and ST (Spontaneous/Time which provides a back up rate if needed) Modes. All of these features allow this device to cover a wide range of applications, including the treatment of COPD/Emphesema, degenerative neuromuscular diseases like ALS, and MS, as well as the treatment of chronic hypoventilation commonly seen in obese patients. Pressure range of 4-30cm h20.

Respironics Legacy Series devices both CPAP and BIPAP, remain very popular with CPAP users, and is the reason we still offer this older model unit to our customers. Any questions, please feel to call or email our representative. We look forward to hearing from you.
