The AirTAC GFR200-08 AirTAC Filter Regulator NPT1/4, Manual Drain 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 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one compact body. This configuration is size 200 with a 1/4 in NPT port, a manual drain on the polycarbonate bowl, a 40 um filter element, a round pressure gauge reading in psi, and a built-in reverse (check) valve; it is ordered without a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and the regulated outlet is adjustable from 0.05 to 0.9 MPa (7-130 psi).
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in and PT, G or NPT threads. Drain type, filter grade (40 um standard, 5 um optional), gauge style and scale, bracket and check-valve options can be selected to suit your installation. Flow is published as curves rather than a single rating, so we confirm datasheet and sizing figures 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.
| GFR200 | G-series filter regulator, 200 body — sets the port range. |
|---|---|
| 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)). |
| (blank) | Standard 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. |
| 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. |
| K | Reverse-flow (reflux) valve fitted. |
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.

Fit the GFR200-08 ahead of the valve manifold on a small pneumatic press or clamping fixture: the 40 um element strips water and swarf from the shop air line while the regulator holds the cylinder pressure the operator has set, and the check valve keeps the set pressure downstream if supply dips.
On a packaging line driving carton cylinders, diverters and sealing jaws from a 1/4 in drop, this filter regulator cleans the air and gives each station its own stable, adjustable pressure without needing a separate filter and regulator in the panel.
Machine shops use a compact filter regulator at the CNC cabinet to condition the air feeding the tool changer and air blast: clean, regulated air at the tool changer, with the built-in check valve helping hold pressure during momentary supply fluctuations.
Step up through sizes 200, 300, 400 and 600 as port size and flow demand grow; this unit is size 200 with a 1/4 in NPT port. For drainage, choose manual (as here) where the bowl is checked routinely, or automatic or differential-pressure draining where the unit runs unattended. Filtration is 40 um standard; specify the W option for 5 um where finer protection is needed. Gauges: an embedded square gauge is standard and an external round gauge is optional, with MPa, psi or bar scales - this unit carries a round gauge reading psi. Thread: PT is the catalogue standard, with G and NPT as orderable options (this unit is NPT). A bracket is optional (not fitted here), and the reverse/check valve is fitted on this code. 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. 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, not as a single rated figure, so we do not quote a number. Tell us your application and downstream demand and we will confirm the sizing from the datasheet curves on request before you order.
The M code means the polycarbonate bowl is drained by hand: open the drain periodically to release collected water. If the unit sits where it is not checked often, the GFR series is also available with automatic or differential-pressure draining - those variants can be quoted on request.
