AFR and BFR filter-regulators combine particle filtration, water separation and adjustable air pressure in a compact assembly. A push-in locking knob helps retain the pressure setting. AFR2000 uses an exposed transparent bowl, while BFR models include an iron bowl guard.
| Model | Port Rc(G) | Maximum flow, L/min (ANR) | Bowl guard |
|---|---|---|---|
| AFR2000 | 1/4″ | 650 | Without |
| BFR2000 | 1/4″ | 1400 | Iron guard |
| BFR3000 | 3/8″ | ||
| BFR4000 | 1/2″ |
The ordering code combines the AFR or BFR family with the port-size suffix: 2000 for 1/4″, 3000 for 3/8″ and 4000 for 1/2″. AFR is offered as AFR2000; the larger port options belong to BFR.
