The Fuji Electric VFC300A-5W is a regenerative ring compressor rated at 0.5 hp on a three-phase 575V AC supply at 60 Hz. It pulls a maximum vacuum of 45 in wc and delivers up to 56 cfm at a maximum operating pressure of 49.8 in wc — numbers that tell you it's sized for moderate-duty air movement, not high-pressure blow-off.
Enclosure is Totally Enclosed Fan-Cooled (TEFC) with an aluminum housing, so it sheds heat in a dusty or humid environment without letting particulates into the windings. Inlet and outlet are both 1-1/4 in NPT female, which means you can plumb it with standard pipe fittings — no adapters to hunt down on site. Class B NEMA insulation and pilot-duty thermal protection built in. The 0.75 A full-load current on 575V AC keeps the branch circuit small.
