WE'VE MOVED!

Airflow is now open at 20 Abros Place, Burnside, Christchurch!

We're settling into our new premises, with stock orders being processed and dispatched as usual — please allow a little extra time while we unpack.

Our manufacturing equipment is gradually coming back online, with most manufacturing expected to resume over the next couple of weeks.

In the meantime, we'll do what we can!

Thanks for your patience and support as we settle into our new home!
