The AirTAC GFR600-20MF1T AirTAC Filter Regulator NPT3/4 3/4 in is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT3/4" ports, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR600-20MF1T is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration carries a 3/4 in NPT port, a 40 um standard filter element, a manual drain on the bowl, and a fitted embedded square gauge scaled in MPa. The maximum inlet pressure is 1.0 MPa (145 psi), the set pressure range is 0.05-0.9 MPa (7-130 psi), and the operating temperature is -5 to 70 C (non-freezing). At size 600 the bowl is aluminium alloy, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with a choice of ports, PT/G/NPT threads, manual, automatic or differential-pressure drains, a 5 um element option (code W), gauge scale options, and a reverse/check valve option. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures for your application on request.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.05 - 0.9 MPa (7 - 130 psi). Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

|---|---|
| 20 | Port size PT3/4". This body offers 20 = PT3/4", 25 = PT1". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |

Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Filtering and regulating the air feeding paint spray guns, so water and particles are stripped out and gun pressure is held steady at the booth.
Conditioning the 3/4 in main feeding cylinders and grippers on a cartoning or case-packing conveyor, with the square MPa gauge giving operators a visible set pressure.
Supplying clean, regulated air to test rigs and pneumatic fixtures in an R&D lab, where the manual drain suits intermittent, supervised use.
Start with the port and size: the 3/4 in NPT connection on this size-600 unit suits lines with higher air demand, and the next step up or down in size changes the available flow. Choose the drain to match maintenance habits: manual drain (as here) needs someone to open it, automatic drain empties itself, and differential-pressure drain is the catalogue default. Filter grade is 40 um standard; specify code W for 5 um where finer particle capture matters. Gauge scale can be MPa, psi or bar, and the thread can be ordered as PT (standard), G (BSPP) or NPT. A bracket is included; J codes omit it.
Because flow is published as curves rather than a single rating, we cannot quote one number here. Send us your application details and we will confirm sizing against the datasheet before you order.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for this family as curves, not as a single rated figure, so we do not state a number. Tell us your application and we will confirm the flow from the datasheet on request before you order.
The M in the code means the bowl has a manual drain: someone opens it to release collected water. If you prefer the bowl to empty itself, the automatic-drain version (code A) or the differential-pressure default is available in the same GFR600 size - just order the corresponding code.
