Air Compressor Choice

Mine is a Sanborn 7.5 hp with an 80 gallon tank,it's all Cast Iron,motor too.15yrs old now,and I'm running all 3/4" hard line.It'll air file,DA,paint,sandblast all day no problem,all I do is change oil and filters and drain the tank.On a side note,make sure your compressor has plenty of fresh air.
