The AirTAC GFR20006LJC1WTK AirTAC Filter Regulator NPT1/8 Low-Pressure 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 PT1/8" 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 GFR20006LJC1WTK is a GFR200-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is the 200 size with 1/8 in NPT ports, the low-pressure regulator type, a fine 5 um filter element (code W), a differential-pressure drain on the polycarbonate bowl, a round external gauge with MPa scale, and a built-in reverse/check valve that holds downstream pressure when the supply is removed. No mounting bracket is fitted. 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 filter-regulator line spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drains, 40 um standard or 5 um fine filtration, standard or low-pressure regulation, gauge and scale options, and G (BSPP), NPT or PT 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.

| (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. |

| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge scale: MPa. 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. |

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.

Feeding clean, low-pressure regulated air to instruments, transducers and small actuators on a test bench, where the 5 um element and round MPa gauge keep the supply visible and fine-filtered.
Supplying pilot and control air to small valves and logic circuits on packaging and labelling lines, with the check valve holding the control side pressurised during supply dips.
Mounted at the inlet of a compact control panel or manifold, filtering condensate and particles from the plant air and regulating it down to the low pressures the panel circuit requires.
Start with the port step: this unit is the 200 size with 1/8 in NPT ports, so match it to the line size and the air demand of the circuit it feeds. The low-pressure regulator type (code L) is intended for circuits that work below the standard regulator's range; the exact adjustment range for this low-pressure version is not published, so confirm it with us against your setpoint. The 5 um element (code W) suits air that feeds valves, cylinders or instruments directly; the 40 um standard element is the usual choice for general line protection. Drain is differential-pressure as standard, which bleeds condensate in service without manual intervention. The round gauge reads in MPa, with psi and bar scales available as options, and the check valve keeps the downstream side pressurised on air loss.
Flow for this series is published as curves, not as a single rated number, so we cannot honestly quote one here. Send us your application details and we will confirm sizing and the datasheet figures before you order. Thread is NPT here; G (BSPP) and PT are catalogue options on the same series.
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, not as a single rated figure, so there is no honest one-number rating we can quote. Tell us your line size, operating pressure and air demand, and we will confirm the flow curve and datasheet figures for this exact model on request before you order.
W is the filter grade code: this unit carries the 5 um fine element instead of the 40 um standard element, which is the right choice when the air feeds valves, cylinders or instruments directly. The drain is the differential-pressure type as standard, so condensate is discharged in service without a manual drain or an automatic float. If your application stops and starts often, ask us about the automatic-drain option in the same series.
