Refurbished Covidien Puritan Bennett 840 Ventilator

Soma Tech Intl offers the Covidien Puritan Bennett 840 Ventilators up to 50% below OEM prices with the same service and warranty as new. The Puritan Bennett is technically refurbished and cosmetically refurbished to make it work and look new. When the refurbishing process starts on the PB 840, it is carefully inspected and tested by our in-house biomedical engineers, who are highly skilled and certified to work on Ventilators. If necessary, parts are replaced to ensure all aspects of the ventilator are to the original engineering manufacturer’s specifications. This ensures that the unit is working the same way that it originally left the manufacturer. After the Covidien PB is working like new, it undergoes a special cosmetic restoration process.
