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 compact filter regulator that removes water and particulate from compressed air and sets a stable downstream pressure in a single body. This configuration is the size 200 unit with a 1/4 in NPT port, 40 um standard filtration, a manual drain bowl in polycarbonate, and an embedded square gauge scaled in MPa. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and the maximum inlet pressure is 1.0 MPa (145 psi). Operating temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options include automatic or differential-pressure drains, a 5 um filter element (code W), psi or bar gauge scales, an external round gauge, G (BSPP) or NPT threads, and a reverse/check valve. Rated flow is published as curves rather than a single figure, so we confirm flow and datasheet details on request before you order.

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.

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.

Clean, regulated air feeding a directional-valve manifold on an automated assembly station, with the square gauge giving the operator a direct pressure readout at the panel.
Point-of-use supply for pneumatic cylinders and grippers on a packaging conveyor, where the manual drain bowl is emptied during routine shift checks and the 40 um element keeps debris out of the actuators.
A filtered, regulated drop at an individual workbench or cell on a factory air ring main, letting each station set its own pressure independently of the header line.
Start with the port step: the GFR200 in 1/4 in NPT suits lighter duty lines, while GFR300/400/500-class sizes step up in port and flow capacity - match the size to the air demand of the circuit rather than oversizing by habit. This unit has a manual drain, which is the right choice where someone visits the machine regularly; choose the automatic drain variant for enclosed or infrequently attended installations, or the differential-pressure drain as the default. Filtration is 40 um as standard; specify the W code for 5 um where downstream valves or instruments need finer protection.
Gauge options are the embedded square gauge fitted here (MPa scale) or an external round gauge, with psi and bar scales available. Thread is NPT on this unit; PT is the catalogue standard and G (BSPP) is an order option. A mounting bracket is included. Because rated flow is published only as curves, not a single number, 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 performance curves rather than a single rated figure, so we do not quote a l/min or SCFM number. Tell us your application and required downstream flow and we will confirm the correct size from the datasheet on request before you order.
The M code in GFR20008MF1T specifies a manual drain bowl, which is emptied by hand during routine maintenance. If the unit will be mounted where it is not visited regularly, the automatic drain (code A) or the differential-pressure drain (the default) are available alternatives in the same series.
