The RB0021 is an air-cooled, direct-drive, oil-sealed, rotary-vane vacuum pump that pulls sample air through the TGA100A. It is supplied with oil, a suction hose (user-specified length), and all of the fittings needed to connect to the TGA100A. The RB0021's capacity is adequate for most TGA100A applications; for applications requiring a larger capacity refer to the RA0040-L.
