The AirTAC GFR20008LJC1TK 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 GFR200 series combines water and particulate filtration with pressure regulation in a single body, so one 1/4 in NPT connection both cleans the air and holds a steady downstream pressure. This unit is the low-pressure type, fitted with a round MPa gauge, a reverse (check) valve and the standard differential-pressure drain; the 40 um element is the standard filter grade. The polycarbonate bowl lets you see accumulated condensate at a glance.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with ports from 1/8 to 1 in, and options include a 5 um element (code W), automatic or manual drains, embedded square or external round gauges with MPa, psi or bar scales, G (BSPP) or NPT threads, and a mounting bracket. Max inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Rated flow for this series is published as curves rather than a single figure, so ask us to confirm sizing and 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. |
| 1 | Gauge scale: MPa. 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. |
| 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.

Filtering and regulating header air down to the reduced setpoints a spray booth or finishing gun circuit needs, with the 40 um element keeping water and particles out of the paint air.
Cleaning and regulating air for the low-pressure cylinders and blow-off nozzles on a carton-sealing or wrapping conveyor, with the check valve preventing backflow through the unit when supply is shut down.
Providing filtered, low-pressure regulated air to bench-top test rigs and pneumatic instrumentation, where the round MPa gauge gives a clear local readout of the set pressure.
Choose the size by port and air demand: size 200 with a 1/4 in NPT port suits compact branch lines, while the 300, 400 and 600 sizes step up port and flow capacity. This unit is the low-pressure type (code L); its exact adjustment range is not published in our data, so confirm the setpoint you need with us before ordering. Drain options are differential-pressure (standard on this unit), automatic (A) or manual (M). Filter grade is 40 um as fitted here, or 5 um with code W for finer filtration. Gauges come as an embedded square gauge or an external round gauge like this one, with MPa, psi or bar scales. Thread is NPT on this model; PT is the standard and G (BSPP) is also a catalogue option. A mounting bracket can be ordered - this unit is supplied without one. Flow for the series 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 series as curves rather than a single rated figure, so we do not quote a number here. Tell us your inlet pressure, set pressure and expected air demand, and we will confirm the datasheet flow curve and correct sizing for this unit on request.
This unit carries the differential-pressure drain, the standard drain option for the GFR family. If your application suits a fully automatic drain or a manual drain valve instead, both are catalogue options (codes A and M) that we can quote for the same filter regulator.
