The AirTAC GFR20008MLF2G AirTAC Filter Regulator G1/4 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 GFR20008MLF2G is an AirTAC GFR200 filter regulator: one compact body that removes water and particulate from compressed air and regulates downstream pressure. This configuration carries a G1/4 (BSPP) port, a manual drain bowl in polycarbonate, a 40 um standard filter element, and the low-pressure regulator type for applications that run at reduced working pressures. An embedded square gauge with a psi scale is fitted so the set pressure is visible at the unit, and the mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with matching port steps, and options include a 5 um element (code W), automatic or differential-pressure drains, alternative gauge scales (MPa, psi, bar), and G or NPT threads in place of the PT standard. 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. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |

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.

Pneumatic clamp and hold-down cylinders on carton-sealing or wrapping machines often run at reduced pressure to avoid crushing product. This filter regulator cleans the supply and lets an operator set and read the low working pressure on the psi gauge.
Bench-top test rigs and small process skids need clean, dry, gently regulated air for actuating valves and cylinders. The 40 um element handles water and particulate, the manual drain suits a supervised bench, and the square psi gauge makes setpoints repeatable.
Control panels driving positioners, pilot valves and small actuators need filtered air at a stable low pressure. This unit filters and regulates in one body at the panel inlet, with the included bracket mounting it directly to the panel frame.
Start with the port step: size 200 with a 1/4 in port suits lighter air demand, and the GFR family steps up through sizes 300, 400 and 600 as required flow grows. This unit is the low-pressure type, so confirm its regulation range against your setpoint - the exact figure is not published and we will confirm it on request. Drain choice matters: this unit has a manual drain, which suits attended installations where an operator bleeds the bowl on a routine; automatic or differential-pressure drains suit unattended lines. The 40 um element is standard; specify 5 um (code W) where finer particulate removal is needed. The fitted square gauge reads in psi; MPa and bar scales are alternatives. Thread is G (BSPP) here, with PT standard and NPT available to order, and the bracket is included. 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 curves, not as a single rated number, so we do not quote a figure. Tell us your application and we will confirm the flow and full datasheet figures for this exact model on request before you order.
The M in the code specifies a manual drain: condensate collected in the polycarbonate bowl is released by hand. It suits attended installations with routine checks; for unattended lines, the automatic (A) or differential-pressure (blank) drain options are the better choice.
