The AirTAC GFR20008LJC2TK AirTAC Filter Regulator NPT1/4 Low-Pressure 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 differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR20008LJC2TK is a 200-size filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This configuration carries 1/4 in NPT ports, the standard 40 um filter element, the differential-pressure drain, the low-pressure regulator variant, a round gauge scaled in psi, and a fitted reverse (check) valve; no mounting bracket is included. The polycarbonate bowl (200 size) allows a visual check of collected condensate. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans four sizes (200, 300, 400 and 600) with ports from 1/8 to 1 in, and options that include automatic, manual or differential-pressure drains, a 5 um element (code W), gauge scales in MPa, psi or bar, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application before ordering.

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.

|---|---|
| 08 | Port size PT1/4". This body offers 06 = PT1/8", 08 = PT1/4". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 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. |
| (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.

Filtered, regulated air at reduced set-points for pilot valves and small actuators on a form-fill-seal line, with the fitted reverse valve blocking backflow toward the supply.
Clean, 40 um-filtered air regulated to a gentle setting for drying or blow-off nozzles over the line, with the round psi gauge giving a direct read of the set-point.
Stable low-pressure air for sensitive instruments and spray apparatus, protected by the 40 um element and monitored on the psi gauge.
Choose the size by the air your process needs: GFR200 is the smallest step in the range with 1/4 in NPT ports here, while 300, 400 and 600 sizes suit progressively larger ports and higher demand. Drain type is a real decision: this unit uses the differential-pressure drain, the catalogue default, with automatic and manual drains available as alternatives. The standard element is 40 um; specify code W for the 5 um grade when downstream equipment needs finer filtration. Gauge scale (MPa, psi or bar - psi here), thread family (PT is the standard; G and NPT are order options) and the bracket choice complete the decode. Because flow is published only as curves, not a single rating, send us your flow and pressure requirements 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes G-series flow as curves rather than a single rated figure, so there is no one number we can quote. Send us your required flow and working pressure and we will confirm the figures from the datasheet on request before you order.
It selects the low-pressure regulator variant, intended for applications that run below the standard regulator range. The exact adjustment range for this variant is not published in the catalogue, so confirm it with us for your set-point. The rest of the code decodes as 1/4 in NPT ports, 40 um element, differential-pressure drain, round psi gauge and a fitted reverse valve.
