The AirTAC GFR20008MLJC2WG AirTAC Filter Regulator G1/4, 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 GFR20008MLJC2WG is an AirTAC GFR200 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This configuration is built with a G1/4 (BSPP) port, a 5 um filter element for finer air cleaning than the standard 40 um grade, a manual drain for the polycarbonate bowl, and a low-pressure regulator type. A round pressure gauge reading in psi is fitted, and no mounting bracket is included with this version.
This is a genuine AirTAC part from the G-series range, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, drain choices, filter grades, gauge styles and thread options (PT standard, G and NPT to order). Published flow data appears as curves rather than a single rating, so we confirm the datasheet and sizing 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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)). |
| L | Low-pressure 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. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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.

A workholding fixture that needs its clamps held at a deliberately reduced supply pressure gets both clean air and gentle regulation from one G1/4 body, with the fitted psi gauge letting an operator verify setpoint at a glance.
Upstream of a directional-valve manifold on a cartoning or wrapping line, the 5 um element strips fine particulate and water that would score spool surfaces, while the regulator section sets a stable supply pressure for consistent valve actuation.
A test bench or lab rig running instruments and small air cylinders at reduced pressure uses the low-pressure regulator type to dial supply down carefully, with manual drain suiting intermittent, supervised operation.
Choosing within the GFR line comes down to real, decodable options: step up through sizes 200, 300, 400 and 600 as your port size and air demand grow - this unit is the 200 size with a 1/4 inch G-thread port. Drain type matters: manual drain means someone vents the bowl, while automatic and differential-pressure drains handle condensate without attention. Filter grade is 40 um standard or 5 um (code W) for finer filtration - this unit carries the 5 um element. Gauge style and scale (square embedded, or round external in MPa, psi or bar) and the presence of a bracket are also order choices.
One honest note before you order: AirTAC publishes flow for this family as curves, not as a single rated figure, and the exact regulation range of the low-pressure type is not stated in the material we hold. Ask us to confirm sizing and the low-pressure range against your application before ordering.
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 family as curves rather than a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow curve and sizing from the datasheet on request before you order.
The M in the code specifies a manual drain: condensate collected in the polycarbonate bowl is released by hand, which suits supervised or intermittent-duty installations. The same GFR200 body can be ordered with an automatic drain (code A) or the default differential-pressure drain if you prefer Hands-off condensate handling.
