is proud to be the exclusive outlet for all Breas/HDM
Factory Refurbished Travel CPAP devices.
The Z2 Auto CPAP
capitalizes on the shell of the Z1 CPAP, with a redesigned,
quieter blower motor, an added Auto Start /Stop Feature and an improved algorithm that seeks to provide greater comfort. HDM is now including a free Qtube to further help muffle the mask-level noise output. Dimensions on the Z2 Travel CPAP are the same as the Z1,
at 6.48” x 3.30” x 2.02” and weighing the same at 10.5 oz - so it
retains the title of the
lightest, compact travel CPAP machines on the market today.

rate/algorithm updates of several times per second, the Z2 Auto provides therapy at a lower overall average pressure than a traditional fixed-pressure CPAP.
Extremely light. Only 10.5 oz
The Z2 Auto is one of the lightest Auto-CPAP machine on the market. Perfect for everyday usage, but ideal for travel.
Compatible with the PowerShell, optional integrated battery
The Z2 Auto CPAP is fully compatible with the optional integrated battery system called the PowerShell®. It delivers a full night of cord-free power on a fully-charged battery. The Extended Life battery is a rechargeable lithium ion battery that you can charge during the day for a night’s worth of therapy.
This PowerShell is great for travel where power is limited or even off the grid.
Z-Breathe® Comfort Feature
One of the most frequent complaints from CPAP users is the difficulty in exhaling against the pressure exerted by the CPAP machine. Z-Breathe is a comfort feature, not unlike CFLEX or EPR, designed to minimize the typical pressure swings due to the spikes in pressure during exhalation and drops in pressure during inhalation to deliver a more comfortable therapy. Z-Breathe has 3 settings so you can set it to suit your own personal needs.
Auto Start / Stop Feature
The Z2 Auto’s firmware comes with the new Auto Start / Stop Feature. Simply place the mask on your face and the therapy will start when the device senses that you have started to breathe. The Z2 will then stop delivering therapy within seconds of the mask being removed from the face or when a large leak is detected.
As with the Z1 Travel CPAP, the Z2’s Ramp feature allows you to start your pressure at a lower setting and ramp it up over time to let you adjust more gradually to CPAP therapy.
Free iOS and Android mobile app for data
The Z2 Auto CPAP is data-capable and records all information on events and compliance. Download the free Nitelog® mobile app for iOS or Android and sync directly to your device with Bluetooth®. Review your data or share it with your doctor directly from the app.
Nitelog can be downloaded from the HDM site
International travel is not a problem with the Z2 - just like the Z1, the power supply automatically adjusts from 100 to 240 volts. All you need to add is the International plug adapter for the country you are visiting. SecondwindCPAP offers this adapter on our
The Z2 Auto also complies with RTCA/DO-160, Section 21, Category M and can be considered FAA compliant and able to be used aboard an aircraft without further testing. The Z2 Bluetooth must be in the off position similar to any other mobile device to maintain compliance.
HME – Waterless Humidification
The Z2 Auto CPAP comes with a small, portable humidification cartridge called an HME (Heat Moisture Exchanger). When inserted between the hose and the mask, it captures the moisture in the exhaled breath and releases it on the inhaled breath. It does not require any electricity or additional water. No more hunting for distilled water when you reach your destination. This filter does not impede flow of air on your device.
No Proprietary Mask Required
The Z2 CPAP and Auto CPAP doesn't require a
specific CPAP mask or tube-tube to operate. Any
mask will fit with this CPAP machine.
The Z2 CPAP and Auto CPAP can be operated with the 4’ long, Slim Style tube that it comes with. The Slim Style tube is also available in a 6’ length. Or it can be used with a standard 19 mm tube.
