The AirTAC GFR20008MJF2WT AirTAC Filter Regulator NPT1/4, 5 um is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT1/4" 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 GFR20008MJF2WT is a GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one compact body. This size 200 unit has a 1/4 in NPT port, a 5 um filter element (the finer W grade, versus the standard 40 um), and a manual drain, so condensate is released by opening the drain when you choose. The J code means no mounting bracket is supplied, and the fitted gauge is the embedded square type reading in psi. Regulation range for this manual-drain configuration is 0.05-0.9 MPa (7-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). The polycarbonate bowl suits this size; only the 600 size uses an aluminium alloy bowl.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with matching port sizes, and options include drain type (differential-pressure, automatic or manual), filter grade (40 um standard or 5 um W), gauge scale (MPa, psi or bar), thread (PT standard, with G and NPT as orderable options), bracket and a reverse/check valve. Rated flow is published only as curves rather than a single 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.

| 08 | Port size PT1/4". This body offers 06 = PT1/8", 08 = PT1/4". |
| 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. |
| J | Supplied without bracket. |

| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 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.

Feeding clean, regulated air to tool changers, clamps and air blast nozzles on a CNC machining centre, where the 5 um element protects precision valves from particles and water carryover.
Conditioning the supply to pneumatic cylinders and grippers on a packaging or bottling line, holding a steady regulated pressure so pick-and-place motions stay repeatable through the shift.
Filtering and regulating the air feeding a directional-valve manifold on an assembly station, with the psi square gauge giving operators a local setpoint check at the panel.
Start with the port and size step: GFR200 carries a 1/4 in port, and stepping up to GFR300, GFR400 or GFR600 gives larger ports and higher flow capacity - match the step to the air demand of the circuit rather than the fitting alone. This unit is already configured with the finer 5 um element; choose 40 um where general plant air protection is enough and 5 um where downstream valves or instruments need cleaner air. Drain type matters in practice: manual drain (this unit) needs someone to open it periodically, while automatic and differential-pressure drains discharge condensate without attention - pick manual only where checks are part of the routine. The embedded square gauge here reads in psi; MPa and bar scales are available, and an external round gauge is an option. Thread is NPT on this unit; PT is the AirTAC standard and G (BSPP) is also orderable. No mounting bracket is included with the J code, so plan the mounting accordingly.
Because flow is published as curves rather than a single rating, we do not quote one number here - send us your application details and we will confirm sizing against the datasheet before you order.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as curves rather than a single rated figure, so we do not state a number here. Tell us your application and we will confirm the flow and datasheet figures for this exact model on request before you order.
This unit's M code is a manual drain: condensate collects in the polycarbonate bowl and is released when someone opens the drain, so it suits installations checked as part of a routine. If you want condensate discharged without attention, the GFR family is also available with automatic or differential-pressure drains - ask us for the equivalent model.
