The AirTAC GFR20008MLJF2GK 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 water and particulate filtration with pressure regulation in a single body, so one compact unit both cleans the compressed air and holds the downstream pressure where the circuit needs it. This configuration, GFR20008MLJF2GK, is the size-200 unit with a G1/4 (BSPP) port, a 40 um standard filter element, a manual drain bowl in polycarbonate, and the low-pressure regulator type for circuits that run below standard line pressures. It is fitted with the embedded square gauge scaled in psi and a reverse/check valve, and it is supplied without a mounting bracket.
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with a choice of ports, drain types (differential-pressure, automatic or manual), 40 um or 5 um (W) filtration, gauge scale, thread option (PT standard; G and NPT orderable) and bracket choice. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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. 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.

|---|---|
| 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. |
| J | Supplied without bracket. |
| (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 clamps and light pneumatic presses on a fabrication cell, where the low-pressure regulator type holds a reduced working pressure to the fixtures while the 40 um element keeps rust and pipe scale out of the clamp cylinders.
Supplying carton sealers, labellers and wrapper cylinders on a packaging line, with the check valve holding the set pressure against backflow and the manual drain cleared during the shift-end maintenance round.
A take-off point on a conveyor system running air jets and diverters, where the G1/4 port suits branch drops from the main line and the psi-scaled square gauge lets operators verify set pressure at a glance.
Start with the port and size step: the 200 frame in this code carries a G1/4 port, and larger frames (300/400/600) step up in port and flow capacity, so match the frame to the air demand of the circuit. Because flow is published as curves and not as a single rated number, ask us to confirm sizing against your application before ordering. This unit is the low-pressure regulator type, so confirm its adjustment range against your working pressure on request. The manual drain (code M) means someone opens the bowl drain during maintenance rounds rather than relying on an automatic or differential-pressure drain, which suits duties with regular operator attention. The 40 um element is the standard grade; the 5 um W grade is available if finer filtration is needed. The embedded square gauge here reads in psi (scales MPa, psi and bar are available, and an external round gauge is optional). Thread is G (BSPP) in this code; PT is the standard and G/NPT are orderable options. A bracket can be added if panel or wall fixing is required; this code is supplied without one.
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 flow for the GFR series as curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Tell us your application and we will confirm the flow data from the datasheet and check the sizing against your demand on request.
The M in the code selects a manual drain: the bowl is emptied by hand during maintenance instead of automatically, which suits installations with regular operator attention; automatic and differential-pressure drains are available in the family if preferred. This code is also the low-pressure regulator type; its exact adjustment range is not published in the standard tables, so ask us to confirm it from the datasheet for your working pressure.
