"When we're working it's very intense and we're very focused on what we're doing," he said. "This is a great time in a relaxed open doors manner. We can give something back to the community.
"The public can see what they have supported over the last 22 years."
He said the rescue helicopter crew worked with all the other emergency services so it was a natural fit to ask them along.
As well as being able to meet crews people can sit in the helicopter, there will be a sausage sizzle and a raffle to win a 15 minute "non-emergency" flight in the helicopter.
The event is free but Mr Vincent said any donations would be gratefully accepted.
