The AirTAC GFR200-08 NPT1/4 AirTAC Low-Pressure Filter Regulator 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 PT1/4" ports, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The GFR200-08MLJC1WT is an AirTAC GFR-series filter regulator: a 5 um filter element and a pressure regulator built into one body, so a single 1/4 in unit both removes water and particulate and holds your downstream pressure. This configuration is the low-pressure type with a manual drain, a round pressure gauge reading in MPa, NPT1/4 ports, no mounting bracket and no reverse/check valve. The polycarbonate bowl shows accumulated condensate at a glance, maximum inlet pressure is 1.0 MPa (145 psi), and the operating 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 in to 1 in, a choice of manual, automatic or differential-pressure drains, 40 um standard or 5 um (W) filtration, and square or round gauges on MPa, psi or bar scales. 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.

|---|---|
| 08 | Port size PT1/4". This body offers 06 = PT1/8", 08 = PT1/4". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 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. |
| 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.

Feeds a spray booth's gun circuit with air that has passed a 5 um element and is held at the reduced setting the low-pressure regulator type is intended for; the manual drain is emptied at shift end so condensate never reaches the finish.
Sits at the drop of a packaging line's main air header and supplies clean, regulated 1/4 in air to the case-taping and pick-and-place cylinders, with the round MPa gauge giving the operator a visible setpoint.
On a lab or QC bench, the 5 um element keeps moisture and particles out of sensitive test fixtures while the regulator drops header pressure to the level the rig needs; the manual drain suits intermittent, supervised use.
Size the unit by port and expected demand: this 200-size body carries 1/4 in NPT threads, while larger sizes step up to 3/4 in and 1 in ports for heavier circuits. Drain choice matters: manual (this unit) is emptied by hand, automatic drains continuously, and the differential-pressure default drains on a pressure drop. Filtration here is the finer 5 um element; 40 um is the standard grade if that is sufficient. The round gauge reads in MPa, with psi and bar scales as alternatives. PT is the standard thread, with G (BSPP) and NPT as orderable options, and a bracket can be added if this no-bracket version does not suit your mounting. 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 GFR flow as curves, not as a single rated figure, so we do not quote a number. Send us your inlet pressure, required downstream pressure and expected air consumption, and we will confirm the datasheet curve and correct sizing on request.
M means the bowl drains manually: you open the drain by hand to empty collected condensate, which suits supervised or intermittent duty. If the unit will be mounted where access is awkward, the automatic (A) or differential-pressure (default) drain versions empty themselves - ask us to quote that variant.
