The AirTAC GFR20008MLF2GK 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 AirTAC GFR200 series combines filtration and pressure regulation in a single body: compressed air passes a 40 um filter element that removes water and particulate, then a low-pressure regulator sets the downstream pressure. This unit is the 200 size with a G1/4 (BSPP) port, a manual drain on the PC bowl, an embedded square gauge reading in psi, and a reverse/check valve fitted in the regulated line. A mounting bracket is included.
This is a genuine AirTAC part. The GFR family runs from size 200 to 600 with ports from 1/8 to 1 inch, and the catalogue options include manual, automatic or differential-pressure drains, a 5 um element (code W), square or external round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow for this family is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application.

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.
| GFR200 | G-series filter regulator, 200 body — sets the port range. |
|---|---|
| 08 | Port size PT1/4". This body offers 06 = PT1/8", 08 = PT1/4". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| 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. |
| K | Reverse-flow (reflux) valve fitted. |
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 clean, low-pressure pilot air to the pneumatic actuators that control fill, capping and discharge valves on a bottling line. The 40 um element keeps grit out of the valve seats while the low-pressure regulator holds a gentle set pressure and the gauge gives a local readout.
Supplying bench equipment such as agitators, clamps or test rigs that run below main header pressure. The low-pressure regulator suits reduced setpoints, the square psi gauge shows the setting directly, and the fitted check valve prevents back-feed into the regulated circuit.
A compact filter-regulator on the air drop feeding a carton sealer or labeler. The manual drain lets an operator clear accumulated water during shift checks, while the 40 um element protects downstream cylinders, tubing and fittings from moisture and debris.
Every letter in this code is a real ordering choice. Size 200 carries a 1/4 inch port; step up to 300, 400 or 600 where the line needs more flow. The M selects a manual drain, right for points someone visits during routine checks; automatic (A) or differential-pressure (blank) drains suit unattended installs. The blank filter grade is the standard 40 um element; specify W for the 5 um grade. F2 fits the embedded square gauge with a psi scale (MPa or bar scales are alternatives), and K adds the reverse/check valve. Thread is G (BSPP) here; PT is the standard and NPT is an order option. Flow for GFR units is published as curves, not a single rating, so send us your flow and pressure requirements 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes GFR flow as curves rather than a single rated figure, so we do not quote a number here. Tell us your inlet pressure, set pressure and air demand, and we will confirm the sizing from the datasheet before you order.
The M in GFR20008MLF2GK selects a manual drain: someone opens the bowl drain as part of routine checks instead of relying on an automatic mechanism. It suits attended installations with regular walk-rounds. Where the unit runs unattended, order the automatic (A) or differential-pressure (blank) drain option instead.
