The AirTAC GFR200-08 AirTAC Filter Regulator, G1/4, 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 holds a set downstream pressure in one compact body. This 200-size unit is threaded G1/4 (1/4 in), carries a 40 um standard filter element, and drains by hand through its manual drain, so it suits lines that are checked on a regular maintenance round rather than unattended runs. The bowl is polycarbonate (PC), the regulator is the standard type with a 0.05-0.9 MPa (7-130 psi) adjustment range, and the fitted round gauge reads in psi. A mounting bracket is included; no reverse/check valve is fitted.
This is a genuine AirTAC part. The GFR series spans 200, 300, 400 and 600 sizes with port options from 1/8 in to 1 in, thread choices of PT (standard), G and NPT, manual, automatic or differential-pressure drains, a 5 um (W) filter element option, gauge scale choices, and a low-pressure type. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and flow 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.

| 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. |

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.

Feeding carton-sealing and case-erector cylinders at an individual machine station, where a 1/4 in filtered and regulated drop keeps actuators running at a set pressure and the manual drain is emptied on the daily check.
Supplying air to pop-up diverters, stop gates and pusher cylinders on a distribution conveyor, with the 40 um element protecting valve seals from water and debris and the psi gauge giving operators a visible setpoint.
Regulating clean air to pneumatic fixtures and test cylinders on a lab or QC bench, where the 0.05-0.9 MPa adjustment range lets a technician dial in low test pressures and read them directly on the psi round gauge.
Start with the port and flow demand: the 200 size with G1/4 threads is the small end of the GFR range, so step up to 300, 400 or 600 if your line draws more air. Choose the drain to match supervision: manual (this unit) for regularly attended lines, automatic or differential-pressure for unattended duty. The 40 um element is standard; specify the W option for 5 um where finer filtration matters. Gauge scale (MPa, psi or bar - this unit ships with a psi round gauge), thread (PT standard, G or NPT to order) and bracket are all decodable choices. 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 flow for the GFR series as curves, not as a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow figures from the datasheet on request before you order.
The M in the code means the PC bowl drains by hand, which suits lines checked on a regular maintenance round. The same GFR200 size is also available with an automatic drain or a differential-pressure drain for less frequently attended installations - just choose the matching drain code.
