Cleckheaton-based firm Ferno has raised more than £18,000 over the past two years in support of the Yorkshire Air Ambulance.
Staff at the company, which manufactures medical equipment to the emergency services, have cycled, played football, baked cakes and cooked lunch to raise £18,619 for the charity.
Workers visited the Yorkshire Air Ambulance base at Leeds-Bradford Airport to meet paramedics and learn about their role.
The Yorkshire Air Ambulance is an independent charity which needs to raise £7,200 each day to stay in the air.
Ferno managing director Jon Ellis, said: “The team at the Yorkshire Air Ambulance does a fantastic job and everyone at Ferno is very proud to be associated with an organisation that saves so many lives in the Yorkshire region.”
