HD Power Systems HD6510TH3. 10 gallon contractor series air compressor powered by the Honda GX200 Series 6.5 hp engine. It has a 3 head air compressor and twin 10 gallon tank. I bought this compressor when my automotive air compressor motor went down until the replacement motor arrived. It was literally ran for 20 hours with no issues, it ran the whole shop perfectly. I paid $1700 and used for two days until my shop compressor was up and running.
