$32.75
The SMC AR20-N02BG-Z-D is a body size 20 modular air regulator from SMC's AR-D series, configured with 1/4 NPT ports, a mounting bracket, and a round pressure gauge with limit indicator. It holds downstream pressure anywhere from 0.05 to 0.85 MPa (7 to 123 psi) with a relieving exhaust, and the Z option puts psi and °F on the product label with a dual-scale MPa/psi gauge, so it reads correctly on North American equipment straight out of the box.
Replacing an AR20-N02BG-Z-A? SMC has discontinued the AR-A modular regulator series and replaced it with the AR-D series. The AR20-N02BG-Z-D carries the same size, thread, port, bracket, gauge, and psi-unit options, and raises the maximum set pressure from 0.7 MPa to 0.85 MPa. Contact Automation Distribution to confirm fit before swapping on an existing panel.
Key Features
- Wide set range: 0.05 to 0.85 MPa (7 to 123 psi) covers most pneumatic machine and actuator supply pressures.
- Bracket and gauge included: ships with mounting bracket and a round type pressure gauge with limit indicator, ready for panel or wall mounting.
- psi labeling: product label in psi and °F with an MPa/psi dual-scale gauge.
- Easier adjustment: the redesigned AR-D knob is easy to grip when unlocked and locks to prevent accidental setting changes.
- Relieving type: vents excess downstream pressure when the setting is lowered.
- Mounting compatibility: SMC states that brackets and set nuts are common between existing and AR-D products, and the panel mounting pitch is interchangeable between AR(K) and AR(K)-B models.
- Modular design: connects with SMC's AC-D series air filters, lubricators, and other modular F.R.L. components.
