Two-piece, portable, self-contained delivery system suitable for use in-office, nursing homes, hospitals, or wherever on-site dentistry is required, the ProCart I combines a powerful air compressor and separate vacuum pump for actual “four-handed” capability. The ProCart I is a truly lightweight portable system easy to transport. It offers exceptional performance and can easily disassemble into small carrying cases. The air, water, and waste management are all contained inside the unit. Compatible with most common brands of handpieces, the ProCart I will also accommodate fiber optics.
