The AirTAC GFR20008MLF2 AirTAC Filter Regulator PT1/4 Low-Pressure 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 GFR20008MLF2 is a 200-size filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has a PT1/4 (1/4 in) port, a manual drain bowl in polycarbonate, a 40 um standard filter element, and a low-pressure type regulator, so it suits circuits that must run below standard regulator settings. The embedded square gauge fitted here reads in psi, and a mounting bracket is included for panel or wall fixing.
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 G or NPT threads, automatic or differential-pressure drains, a 5 um element (code W), and MPa or bar gauge scales. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application before ordering.

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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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. |

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.

On a machining cell where pneumatic clamps must hold at gentle, carefully limited pressure, this low-pressure type filter regulator cleans the supply and holds the setpoint from one compact 1/4 in unit.
Feeding carton-sealing and case-erector cylinders on a packaging conveyor, the 40 um element keeps scale and pipe debris out of valves while the regulator sets the working pressure for consistent sealing strokes.
At an assembly plant bench drop, the bracket-mounted unit conditions the air for hand tools and small actuators, with the square psi gauge giving the operator a clear local pressure readout and the manual drain emptied at shift checks.
Start with the port step: this unit is 1/4 in PT, and the GFR series steps up through 3/8, 1/2, 3/4 and 1 in as flow demand grows, so match the size to the line rather than oversizing on guesswork. The manual drain here must be emptied by hand, which suits dry, attended installations; choose the automatic or differential-pressure drain versions for unattended duty. The 40 um element is the standard grade; specify the W variant for 5 um where downstream equipment needs finer filtration. This low-pressure type regulator is intended for circuits set below standard regulator ranges - confirm the exact adjustment range with us. Gauge scale is psi on this unit, with MPa and bar available, and PT is the standard thread with G (BSPP) and NPT as order options.
Flow for the GFR series is published as curves, not a single rated figure, so send us your application details and we will confirm sizing against the datasheet before you order.
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 rather than a single rated figure, so we do not quote a l/min or SCFM number. Send us your application details and we will confirm the datasheet flow figures and check the sizing for you before you order.
The M in the code GFR20008MLF2 specifies a manual drain: collected condensate is released by hand rather than automatically. It suits attended installations where someone can open the drain during routine checks; if the unit will run unattended, ask us about the automatic or differential-pressure drain versions of the same filter regulator.
