A £10,000 donation by kind-hearted Flintshire trailer makers can help the Wales Air Ambulance save five lives, according to the charity.
Long-term supporters Ifor Williams Trailers, who have several factories in Deeside, raised around £4,000 at the Urdd National Eisteddfod in Denbigh.
They then matched pound for pound and then rounded up the total to £10,000.
The money was presented to Debra Sima, the Wales Air Ambulance's community fundraiser in North Wales, by Dafydd Jones and Lois Wynne, from Ifor Williams Trailers.

Debra said: "We are extremely grateful to Ifor Williams Trailers for this generous donation. It’s just an incredible amount of money.
“We’re looking at missions costing between £2,000 and £3,000 so that can potentially save about five people’s lives. It’s just mind-blowing.”
The charity has carried out more than 44,000 missions since it was launched on St David's Day in 2001.
From its airbases in Llanelli, Caernarfon and Welshpool and Cardiff, an air ambulance can be anywhere in Wales within 20 minutes of an emergency call.
Debra added: “We’re looking all the time to increasing how many missions we can do so that we can have that bigger impact because we all know the amount of demand on the emergency services is just going up and up and up.
“We now have RRVs, rapid response road vehicles – two at each airbase – and that means we can still be very proactive when the aircraft can’t be out because of the great British weather.

Dafydd Jones, the Show Manager at Ifor Williams Trailers, said: “The charity provides a fantastic, life-saving service to the people of Wales – the crew are real heroes.
“We felt therefore it was wholly appropriate for the Wales Air Ambulance to be our chosen charity this time.
"Without them, there are a lot of people who wouldn't be here now so they really deserve our support.
“It makes us immensely proud to think that the money we have presented to the charity can potentially save the lives of five people.”
