The AirTAC GFR20008MJC2WTK AirTAC Filter Regulator 1/4 in NPT 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 GFR200 series is a filter regulator: it removes water and particulate from compressed air and sets downstream pressure in a single body, so one unit does the job of a filter and a regulator without a separate pairing. This exact configuration, GFR20008MJC2WTK, is the size 200 unit with 1/4 in NPT ports, the fine 5 um filtration element (code W), a manual drain on the bowl, a round pressure gauge reading in psi, a built-in reverse/check valve, and no mounting bracket. The manual drain means an operator opens the drain at the bottom of the bowl to discharge collected condensate, which suits stations that are checked as part of a routine walk-round.
This is a genuine AirTAC part. The GFR family runs from size 200 up to size 600, with port sizes from 1/8 in to 1 in, a choice of drain types, 40 um standard or 5 um fine filtration, gauge styles and scales, and PT, G or NPT threads. Rated flow for this series is published as curves rather than a single figure, so ask us and we will confirm the datasheet figures for your application before you order.

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.
| GFR200 | G-series filter regulator, 200 body — sets the port range. |
|---|---|
| 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. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. 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. |
| K | Reverse-flow (reflux) valve fitted. |
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.

Feeds clean, regulated air to the tool-change and clamping circuits on a machining centre, with the 5 um element and check valve protecting the valves and cylinders that index the machine's fixtures.
Sits at the drop feeding the pneumatic cylinders that erect, fill and seal cartons on a packaging line, holding a set pressure so sealing jaws and pushers repeat consistently through the shift.
Regulates the air feeding pneumatic screwdrivers, riveters and air cylinders at an assembly workstation, with the manual drain emptied during the operator's end-of-shift checks.
Start with the port step: this unit is size 200 with 1/4 in NPT ports, and the GFR range steps up through sizes 300, 400 and 600 with larger ports and higher flow capacity, so match the size to the air demand of the circuit rather than the pipe alone. Choose the drain type to suit how the unit is attended: manual drain (this configuration) is emptied by hand, automatic drain discharges condensate on its own, and the differential-pressure default drains when the pressure differential calls for it. Choose the filter grade: 40 um is the standard element and 5 um (code W, fitted here) protects finer components downstream.
Gauge options are an embedded square gauge or an external round gauge, with MPa, psi or bar scales; this unit carries a round gauge on the psi scale. Thread is PT as the catalogue standard with G and NPT as orderable options - this unit is specified in NPT. A mounting bracket is optional (not fitted here), and a reverse/check valve can be ordered in the code (fitted here). Because flow for this series is published as curves and not as a single rated number, ask us to confirm sizing against your application before ordering.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
We do not quote a single rated flow figure for this unit because AirTAC publishes flow for the GFR series as curves, not as one rated number, and quoting a single value would overstate or understate real performance. Tell us your application and required flow, and we will confirm the datasheet figures for this exact configuration before you order.
It depends on how the unit is attended. The manual drain on this GFR20008MJC2WTK discharges collected condensate when an operator opens it, which works well at stations checked on a routine schedule. If the unit will sit unattended, the automatic drain (code A) or the differential-pressure default drain discharges condensate without anyone opening the bowl, and we can quote that variant of the same size 200, 1/4 in, 5 um configuration.
