Bosch Rexroth 0821300920 Pneumatic Filter Assembly

The Bosch Rexroth 0821300920 is a pneumatic pressure regulator from the AS3-RGS / NL2-DIL series that precisely controls downstream air pressure in compressed air systems. It is designed for use in industrial automation equipment, pneumatic control panels, assembly machinery, and manufacturing lines where stable pressure is essential. The unit features a lockable rotary knob for pressure adjustment and an optional pressure gauge port, with a G 3/8 port size and a G 1/8 gauge port. It regulates from 0.5 to 8 bar (7.3 to 116 psi) and supports a maximum input pressure of 16 bar (232 psi), with a nominal flow of 4300 L/min at 6 bar. The regulator’s body is made of Polyamide (PA) and uses NBR seals, suitable for -10°C to +50°C ambient (some versions up to +60°C), and can be mounted in any orientation. Medium is compressed air or neutral gases, and it serves to maintain constant output pressure to protect downstream components and ensure consistent machine performance. Compatible equipment includes pneumatic systems, control panels, automation machinery, and OEM equipment.
