My air compressor stopped working this week after 10 years of hard use. It was undersized (60 Gallon, 3 HP) and never kept up with an air sander. I'm looking at 80 Gallon 5 HP and 7.5 HP compressors. Will a 5 HP compressor keep up with 1, possibly 2 sanders? I'd love to get everyone's opinion. Are there any brands to stay away from?
