Tafonius

TAFONIUS IS a new, state-of-the-art large animal ventilator that has arisen from a joint co-operation between Hallowell EMC and Vetronic Services LTD.


Designed for the demanding veterinary environment, 
Tafonius has no need for a driving gas supply and has an un-interrruptable power supply that means it can continue running for up to 6 hours in the event of a power failure - that’s all your monitoring and ventilation with no interruption. 
Controlled via a large 15“ touch-screen computer the ventilator is easy to set up and control. There is feedback on ventilation parameters as well as full patient monitoring giving you more control than you have ever had before. Patient data is recorded for later retrieval and the advanced Windows(TM) software allows you to create profiles for different people or patients that allow you to set the machine up just the way you like it.
Large animal ventilation has never been so versatile.

Tafonius has been in development for many years, and has been shown at previous events such as the British Equine Veterinary Association (BEVA).
