Our Story

A CONCEPT BORN FROM A WORLDWIDE NEED
ESPlastics Ltd, an ISO 9001:2015 and ISO 13485:2016 accredited manufacturing company, utilised their existing pharmaceutical platform as a gateway into mechanical ventilation development. 
The team at ESPlastics New Zealand rapidly designed an effective COVID-19 response ventilator with design specifications included catering specifically to a pandemic situation such as COVID-19. 
The Respirator NZ Pandemic Ventilator is manufactured on-site at ESPlastics Ltd, in Hamilton New Zealand. The componentry for the Pandemic Ventilator has been sourced from local suppliers within New Zealand, to ensure a high-quality end product. The Pandemic Ventilator is MedSafe approved for use in New Zealand and is currently in the process of obtaining international medical device registration.

New Zealand moves into COVID-19 lockdown, commencing a four week nationwide lockdown period. Jeff was provided with a ventilator sample, the ‘PENLON Nuffield Series 200 Ventilator’, by his neighbours. 

Using this reputable piece of historical innovation, Jeff Sharp began designing what would eventually come to be, the VC PV I, the first RespiratorNZ Pandemic Ventilator model.
