The AirTAC GFR20008MJF2 AirTAC Filter Regulator PT1/4 Square Gauge 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 GFR20008MJF2 is a size-200 filter regulator that removes water and particulate from compressed air and reduces pressure to your set point in a single compact body. This configuration is tapped PT1/4 (1/4 in), carries a 40 um standard filter element, and uses a manual drain, so an operator opens the drain valve to expel collected condensate on a scheduled basis. The embedded square gauge reads in psi for direct set-point adjustment, the regulator is the standard type with a 0.05-0.9 MPa (7-130 psi) adjustment range, and the polycarbonate bowl is rated for the same 1.0 MPa (145 psi) maximum inlet pressure as the unit itself. Operating temperature is -5 to 70 C (non-freezing), and this version is supplied without a mounting bracket.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in and options including automatic or differential-pressure drains, a 5 um (W) filter element, alternative gauge scales, G or NPT threads, and brackets. Flow is published in the catalogue as curves rather than a single rated figure, so contact us and we will confirm the datasheet and sizing 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.

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 the air cylinder circuit of a small punch press or stamping station: the 40 um element stops pipe-scale and water reaching the valve stack, while the psi gauge lets the setter dial the clamping pressure and lock it in.
Supplying the divertor and stopper cylinders on a packaging conveyor run, where a stable regulated pressure keeps pusher stroke timing consistent shift after shift and the manual drain is bled during scheduled line cleaning.
Conditioning the air feed to a spray gun or coating head in a finishing booth: water and grit are knocked out before the atomising air, and the regulator holds the gun pressure the painter sets on the psi gauge.
Start with the port and size step: GFR200 with a PT1/4 (1/4 in) connection suits lines plumbed at 1/4 in, while sizes 300, 400 and 600 step up in port and capacity - match the step to the flow your circuit needs. Next choose the drain: this unit has a manual drain, which suits installations where an operator can bleed condensate regularly; choose automatic or differential-pressure drain where the unit is inaccessible or condensate loads are continuous. The 40 um element is the standard grade for general plant air; specify the 5 um (W) option where downstream equipment needs finer filtration. The square gauge is fitted here with a psi scale (MPa and bar scales are alternatives), and an external round gauge is optional. Thread is PT as standard with G (BSPP) and NPT available to order, and a mounting bracket can be added if the unit will not hang on the pipe itself. Because flow is published as curves rather than a single rating, 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 number here. Tell us your line pressure and the flow your circuit needs, and we will confirm the datasheet curve and check the sizing for your application on request.
The M in the code sets a manual drain: an operator opens the drain valve to expel the water and oil collected in the polycarbonate bowl. It suits accessible installations with a regular maintenance routine. If the unit is mounted out of reach or condensate accumulates continuously, ask about the automatic or differential-pressure drain versions of the same GFR200 filter regulator.
