The AirTAC GFR20008LF2T 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 GFR20008LF2T is a GFR-series filter regulator: one body that removes water and particulate from compressed air and regulates the downstream pressure. This size 200 unit carries a 1/4 in NPT port, the low-pressure regulator type (code L), a 40 um standard filter element, a differential-pressure drain and a polycarbonate bowl. An embedded square gauge with a psi scale is fitted, a mounting bracket is supplied, and no reverse/check valve 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 from the GFR200 series. GFR filter regulators are available in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, a choice of differential-pressure, automatic or manual drain, an optional 5 um element (code W) in place of the standard 40 um, gauge scales in MPa, psi or bar, and PT, G or NPT threads. AirTAC publishes flow only as curves rather than a single rating, so we confirm flow and datasheet figures for your application on request.

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. |
| (blank) | Mounting bracket included. |

| F | Gauge shape: Square. 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.

Supplying filtered air at a reduced, gently held pressure to spray guns in a paint finishing booth, where the low-pressure regulator type suits setpoints at the low end of the working range and the 40 um element keeps oversize particles away from the fluid tip.
Regulating filtered air to clamp fixtures on a machining cell that handles aluminium or plastic parts, where the holding pressure must sit at a low setting and the differential-pressure drain clears collected condensate without a manual blowdown routine.
Feeding clean, regulated air to the small cylinders and grippers on a packaging conveyor, with the polycarbonate bowl and 40 um element protecting the valves from water and debris carried in the shop air line.
Within the GFR family the real choices are: size and port (200 to 600, 1/8 to 1 in), stepped against the flow your line needs; drain type (differential-pressure as fitted here, automatic, or manual); filter element, 40 um standard or 5 um (W) for finer protection; gauge scale (psi as supplied, or MPa or bar); thread (PT is the AirTAC standard, with G and NPT as order options - this unit is NPT); and bracket inclusion. Regulation range depends on the type: this is the low-pressure (L) version, whose exact adjustment range is not published, so confirm it against your set pressure before ordering. Flow is published as curves, not a single rating - ask us to confirm sizing against your application before you order.
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 GFR flow as performance curves rather than a single rated figure, so we do not quote one number. Send us your required flow and working pressure and we will confirm against the datasheet whether this size 200, 1/4 in NPT unit is correctly sized before you order.
It marks the low-pressure regulator type. The rest of the decode is unchanged: 40 um standard element, differential-pressure drain, embedded square gauge with psi scale, NPT1/4 port and included bracket. Because the exact adjustment range of the low-pressure type is not published in the material we hold, we confirm it on request against your set pressure.
