Bosch Rexroth”s Series AS3 FRL is an air-preparation system featuring modular construction comprised of filters, regulators, lubricators, and accessory devices, such as shutoff valves and distribution blocks. The system provides a max. flowrate of 184 SCFM and is available in 3/8” and 1/2” NPT, with G3/8 and G1/2 ports and a pressure range of 232 PSI. The regulator supports temperatures from 14 F to 122 F. It is a patented oil-filling system that permits semi-automatic filling of the lubricator unit — the oil is directly vacuumed out of a container through a hose and the level is measured and displayed with a sensor. Options include multiple filter options – 5, 0.3, or 0.01 micron filtration. Drain valves on the filters can be semiautomatic or automatic. Regulator options include standard, precision, or continuous pressure models. Shutoff (lock-out) valves can be lockable or non-lockable.
