Roland Johnson uses his air compressor for powering many things in his shop: finish nailers, orbital and inflatable drum sanders, die grinders, blow guns, drills, and as a vacuum generator for his veneer press. Almost every electric tool has an air-driven counterpart with the advantages of lighter weight, variable speed, and longer life. He explains here how air compressors work, what tools work well with them, how to buy one, and how to assess ratings (cfm and psi). He says to look for durable materials and practical sizes and explains how to choose hoses. He details couplers and flexible hoses in various grades and sizes and explains how to maintain the compressor and its parts to extend its life.
