The AirTAC GFR200-08LF1TK 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 GFR200-08LF1TK is an AirTAC GFR-series filter regulator: in one compact body it removes water and particulate from compressed air and holds downstream pressure at a set point. This 200-size unit has a 1/4 in NPT port, the standard 40 um filter element, a differential-pressure drain on the polycarbonate bowl, a low-pressure regulator, an embedded square MPa gauge and a reverse (check) valve; a mounting bracket is included. 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 spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options include automatic or manual drains, a 5 um element (code W), an external round gauge with MPa, psi or bar scales, and G (BSPP) or NPT threads in place of the PT standard. Rated flow is published as curves rather than a single figure, so ask us to confirm sizing and datasheet details for your application.

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.

| F | Gauge shape: Square. 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. |

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 air to cylinder-driven carton closers and clamp arms on a packaging line, where the filter stage protects valves from water and grit while the regulator holds a steady set point stroke after stroke.
Supplying filtered, regulated air to clamping cylinders on machining fixtures, where a stable downstream pressure keeps holding force consistent across a production shift.
Conditioning supply air for spray guns and low-pressure coating stations, where the low-pressure regulator type, 40 um filtration and the check valve against backflow suit the set-up.
The real choices on this family are the size and port step (200/300/400/600, 1/8 to 1 in), matched to the flow your line needs; the drain type (differential-pressure as fitted here, automatic, or manual); the filter grade (40 um standard, 5 um with code W); the gauge (the embedded square MPa gauge fitted here, or an optional external round gauge in MPa, psi or bar scales); the thread (PT is the standard, with G and NPT as catalogue options); and the bracket. This unit is the low-pressure type, so confirm its set-point range against your application before ordering - the exact figure is not published. Flow is published as curves, not a single rating, so send us your flow and pressure requirements and we will confirm the right size from 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 flow for the GFR series as curves rather than a single rated figure, so no single number can be quoted honestly. Tell us your line's flow and working pressure and we will confirm the sizing from the datasheet on request before you order.
This unit's bowl uses the differential-pressure drain, the default option for the GFR family. If your application suits it better, automatic-drain (code A) and manual-drain (code M) versions of the same filter regulator are catalogue options you can order.
