The AirTAC GFR20008LJC1T 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 GFR20008LJC1T is an AirTAC GFR200 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has 1/4 in NPT ports, the standard 40 um filter element, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, and a round pressure gauge reading in MPa. It is the low-pressure (L) type, intended where the working pressure sits below the range of a standard regulator. The polycarbonate bowl suits the 200 size, and no mounting bracket is fitted.
This is a genuine AirTAC part. The GFR line spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and options include manual or automatic drains, a 5 um element (code W), square or round gauges with MPa, psi or bar scales, a reverse/check valve, and G or NPT threads in place of the PT standard. Flow is published as curves rather than a single rating, 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.

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 bagging or tray-sealing machine, sealing bars and hold-down cylinders often run at reduced pressure to avoid crushing film or damaging product. This low-pressure filter regulator cleans the air and holds the set pressure at the station, with the MPa gauge giving the operator a clear setpoint reference.
Process skids and batching lines frequently use small pneumatic pilot actuators that must not be over-pressurised. Feeding them through this unit filters water and pipe scale out of the pilot supply and keeps the pilot pressure in the low band the actuator was specified for.
Bench-top process equipment such as small spray, coating or agitation setups needs clean, gently regulated air at low pressure. The 40 um element protects nozzles and fittings from particulate, the differential-pressure drain keeps condensate moving out during continuous use, and the 1/4 in NPT ports suit compact tubing runs.
Start with the port step: this unit is size 200 with 1/4 in NPT ports, so size up to GFR300/400/600 if your line needs larger ports and more flow. Because this is the low-pressure (L) type, confirm your working pressure falls in the low-pressure band before choosing it over a standard GFR; the exact range is not published, so we will confirm it from the datasheet on request. The differential-pressure drain is the default and suits steady-flow duty; choose automatic (A) for unattended drains or manual (M) where you want operator control. The 40 um element is standard; specify W for the 5 um grade if downstream equipment needs finer filtration. The round MPa gauge is fitted on this code; square gauges and psi/bar scales are alternatives. NPT is ordered via the T suffix, with G (BSPP) also available as an option. 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. 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 series as curves, not as a single rated figure, so there is no one rated-flow number we can honestly quote for this unit. If you tell us your line pressure, set pressure and the flow your equipment needs, we will confirm the sizing against the datasheet curves on request before you order.
L marks the low-pressure type of regulator, intended for applications where the working pressure sits below the range of a standard GFR; the exact range is not published, so we confirm it from the datasheet on request. The drain on this unit is the differential-pressure type: condensate collected in the bowl is bled off automatically whenever air flows through the unit, with no operator action needed. Manual (M) and automatic (A) drains are available on other codes in the family.
