Observe whether the air compressor in question has one or two cylinders. Twin-cylinder compressors are single-stage compressors with two cylinders of equal size that work in parallel with each other. On the homeowner/contractor level, most of the twin-cylinder models operate just like single-cylinder versions, except that there are two strokes per revolution instead of one. - 2). If there are two cylinders on the air compressor in question, listen to whether both cylinders compress air simultaneously, or whether they alternate compression.
- 3). Identify a twin-cylinder air compressor by determining that both cylinders compress air simultaneously. Alternating cylinders indicate a dual- stage air compressor, rather than a twin-cylinder air compressor.
