The AirTAC GFR200-08 AirTAC Filter Regulator, NPT 1/4 in, 5 um 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 AirTAC GFR200-08 is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setpoint in a single compact body. This 200-size unit is fitted with 1/4 in NPT ports, a 5 um filter element (code W) for finer filtration than the 40 um standard, a manual drain for the bowl, an embedded square gauge scaled in psi, and a built-in reverse/check valve that holds downstream pressure if the supply drops. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi), and the operating temperature range is -5 to 70 C (non-freezing). The polycarbonate bowl is protected by the metal bowl guard standard on this size, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and with choices of drain type, filter grade, gauge scale, thread (PT standard, G and NPT as options) and check valve. Flow figures for this series are published as curves rather than a single rated number, so ask us and we will confirm the 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. Standard type, regulating 0.05 - 0.9 MPa (7 - 130 psi). 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. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 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.

Point-of-use conditioning for directional valves and cylinders on a packaging or assembly machine: the 5 um element keeps grit and condensed water out of the valve seats, while the regulator holds a steady actuator pressure and the check valve holds the setpoint through brief supply dips.
A dedicated conditioned drop for bench-mounted test rigs, air bearings and instrument panels, where fine 5 um filtration and a stable, locally adjustable psi-set pressure matter more than raw flow, and the manual drain suits intermittent, attended use.
Feeding air cylinders, air-operated gates and blow-off nozzles along a conveyor line: the filter-regulator sits at the line branch, the square psi gauge lets operators verify set pressure at a glance, and the included bracket mounts the unit to the machine frame.
Start with the port and size step: this unit is 200 size with 1/4 in NPT ports, and the GFR range steps up through 300, 400 and 600 where larger flow is needed - match the step to your air demand rather than oversizing on guesswork. Because flow for this series is published as curves and not as a single rated figure, ask us to confirm sizing against your application before ordering. On this configuration you have already chosen: manual drain (simplest to service, and it widens the regulator adjustment range to 0.05-0.9 MPa / 7-130 psi), 5 um filtration instead of the 40 um standard, a square gauge scaled in psi, and a reverse/check valve. If you would prefer automatic or differential-pressure draining, a different gauge scale (MPa or bar), G (BSPP) threads instead of NPT, or no check valve, those are catalogue options on the same series - tell us and we will decode the right code with you.
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 number, so we do not quote a rated flow, Cv or SCFM figure. Tell us your inlet pressure, set pressure and air demand, and we will confirm the datasheet curve figures for this exact model on request before you order.
The M in the code selects a manual drain: someone opens the drain at the bottom of the bowl to expel collected water, rather than the bowl draining itself. For a manual-drain filter regulator the regulator adjustment range is 0.05-0.9 MPa (7-130 psi), and the drain suits attended installations where the bowl can be checked on a routine walk-round. If the unit will run unattended, ask us about the automatic or differential-pressure drain versions of the same series.
