The AirTAC GFR20008MLJC2K AirTAC Low-Pressure Filter Regulator PT1/4 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 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 GFR20008MLJC2K is a GFR200 filter regulator: one body that strips water and particulate from compressed air and regulates downstream pressure. This configuration uses the size 200 body with 1/4 in PT ports, a polycarbonate bowl with a manual drain, a 40 um standard filter element and the low-pressure regulator type. It is fitted with a round gauge scaled in psi and a reverse (check) valve, and no mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family runs from size 200 to 600 with ports from 1/8 to 1 in, and options across the family include automatic and differential-pressure drains, a 5 um element (code W), embedded square or external round gauges scaled in MPa, psi or bar, and G or NPT threads to order. Because rated flow is published as curves rather than a single figure, we confirm flow and full datasheet details 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.

| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |

| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |

| 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.

On a fixture line where workpieces are held by air clamps running at reduced pressure, this unit filters the supply to 40 um and regulates it in one body, with the manual drain cleared during scheduled maintenance stops.
Bench and pilot rigs that charge vessels or small actuators at low pressure get filtered, regulated air from this unit, and the psi-scaled round gauge lets an operator read the set point directly at the panel.
Ahead of the directional valves on a packaging machine, this filter regulator removes condensate and particulate and sets line pressure, while the fitted check valve blocks backflow in the drop leg.
The decodable choices on this family are: size and port (200 to 600, 1/8 to 1 in) stepped against the flow your line needs; drain type (differential-pressure, automatic or manual - this unit is manual); filter grade (40 um standard, 5 um with code W); gauge type and scale (embedded square as standard, external round optional, MPa/psi/bar); thread (PT standard, G and NPT to order); and bracket. This configuration decodes as PT1/4 ports, manual drain, 40 um element, low-pressure regulator type, round psi gauge, check valve fitted, no bracket. The adjustment range for the low-pressure type is confirmed on request. Flow is published as curves, not a single rating, so 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.
AirTAC publishes flow for the GFR family as curves rather than a single rated figure, so no rated flow number is quoted here. Send us your application details and we will confirm the flow curve and full datasheet figures for this exact unit on request.
This configuration is ordered with a manual drain: an operator opens the drain by hand during scheduled checks to expel collected condensate. If you would rather not rely on manual draining, the GFR family also offers automatic and differential-pressure drains.
