The AirTAC GFR200-08 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 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 AirTAC GFR200-08 is a size 200 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is the low-pressure type, so it suits circuits that run well below standard line pressure. It carries a 40 um standard filter element, a manual drain bowl in PC (polycarbonate), a fitted embedded square gauge scaled in psi, and 1/4 in NPT ports. Maximum working (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 is published in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and options include automatic, manual or differential-pressure drains, a 5 um (W) element, square or round gauges with MPa, psi or bar scales, a reverse/check valve, and G (BSPP) or NPT threads in place of the PT standard. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

|---|---|
| 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. |

| 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.

Point-of-use conditioning ahead of air-powered spray guns: the element strips water and pipe scale that would spoil finish quality, while the low-pressure regulator holds a steady, reduced setting at the gun manifold.
Feeding pilot valves and small actuators on a cartoner or case packer, where the 1/4 in NPT ports suit compact drop legs and the square psi gauge lets an operator verify the set point at a glance.
Conditioning and stepping pressure down for positioners, transducers and other low-pressure instrument devices on a skid, with the manual drain allowing scheduled bowl bleeding during routine rounds.
Start with the port step: size 200 with 08 ports gives 1/4 in NPT here (G and PT threads are order options), and larger sizes move up in both port and flow capacity, so match the size step to the flow your line needs. Because this is the low-pressure (L) type, confirm its regulation range against your working pressure before ordering - the exact figure is not published in the material we hold, and we will confirm it on request. The manual drain (M) means someone bleeds the bowl by hand, which suits intermittently attended points; automatic or differential-pressure drains are available in the family if the installation is unattended. The 40 um element is the standard grade; specify the W code if the application needs 5 um filtration. The fitted square gauge reads in psi (MPa and bar scales are alternatives), and this J-coded version ships without a mounting bracket - a bracket can be specified if you want panel fixing. Flow is published as curves, not a single rating, so send us your application details and we will confirm sizing against the datasheet 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 flow for the GFR series as curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Tell us your application - working pressure and the air your equipment consumes - and we will confirm the sizing against the datasheet on request before you order.
The M in the code means the polycarbonate bowl has a manual drain, so accumulated water is bled off by hand rather than automatically - choose the automatic or differential-pressure drain codes if the unit will be left unattended. The L means this is the low-pressure regulator type, intended for circuits running below standard line pressure; its exact regulation range is not published in our material, so ask us to confirm it on request. The F2 code is the fitted square gauge with a psi scale.
