GFR nine body/port combinations, adjustment ranges, inlet pressure, bowl capacities and weights

Helpful for Model Matching:

Full model or installed label; quantity and destination
Published body/port pair and PT/G/NPT thread
Drain type; GFR200 has no published automatic option
Standard or L low-pressure adjustment; inlet pressure separately
F square / C round gauge with scale, or N without gauge
40/5 μm filter, bracket and K reverse-flow valve
IN/OUT arrows, installation dimensions and bowl clearance

Use the exact GFR body/port installation drawing and distinguish drain outlet from main port
Compare gauge mounting, IN/OUT direction and bowl service clearance
Use GFR flow curves at their printed 0.7 MPa inlet condition; no single rated flow inferred

Matching Questions

Can GFR200-08 and GFR300-08 replace each other because both have 1/4 ports?

A shared main port does not establish fit. GFR200 has a 10 cm³ bowl and 161 mm reference height; GFR300 has 40 cm³ and 225.5 mm. GFR300 offers automatic drain, while GFR200 does not list it. Compare drain, gauge, reverse-flow option, mounting and clearance using the installed label and photo.

Is the 1.0 MPa inlet rating the adjustable outlet-pressure range?

No. Standard adjustment is 0.15–0.9 MPa for differential-pressure or automatic drain, and 0.05–0.9 MPa for manual drain. L limits maximum adjustment to 0.4 MPa. The 1.0 MPa rating is maximum inlet pressure; 1.5 MPa is proof pressure.
