The AirTAC GFR20008MLJC2G 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 GFR20008MLJC2G is an AirTAC GFR200 filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This configuration is the 200 size with a G1/4 (BSPP) port, a 40 um standard filter element, manual bowl drain, and the low-pressure regulator type for circuits that run below standard working pressures. A round pressure gauge scaled in psi is fitted, and the polycarbonate bowl suits the 200 frame. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans the 200, 300, 400 and 600 sizes with port options from 1/8 to 1 inch, thread choices of PT (standard), G and NPT, drain types (differential-pressure, automatic or manual), a 5 um element option (code W), gauge and scale choices, and a reverse/check valve option. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing or any datasheet figure 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.
| 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. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. 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. |
| (blank) | No reverse-flow valve (the default). |
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.

Feeds filtered, regulated air to clamp cylinders on a carton sealing station that runs at reduced pressure, with the psi gauge letting operators set and verify the holding pressure at the machine.
Conditions the compressed air feeding a bench-top test rig or coating applicator, removing water and particles while holding the gentle, stable pressure that low-pressure processes need.
Supplies clean, regulated air to the dispensing valve and material pump on an assembly line dispensing head, where a manual drain suits a shift-based maintenance routine.
Start with the port step: the 200 size carries a 1/4 in port here in G (BSPP) thread, with NPT available to order and PT as the catalogue standard. Because flow is published as curves, not a single rating, match the 200 frame to your line by asking us to check the curve against your air demand. The 40 um element is the standard grade; choose the 5 um W option if downstream equipment needs finer filtration. Drain type is a real operating choice: this unit has a manual drain, so an operator drains the bowl; automatic or differential-pressure drains suit unattended installations. The fitted round gauge reads in psi; square embedded gauges and MPa or bar scales are the other catalogue options. Note this configuration is the low-pressure regulator type and is supplied without a mounting bracket (code J); brackets are a catalogue option. Confirm the exact adjustment band for the low-pressure type with us 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 GFR flow as curves rather than a single rated figure, so there is no one rated flow number we can state. Tell us your line pressure and air demand and we will confirm from the datasheet curve whether the 200 size with the G1/4 port suits your application before you order.
The manual drain means collected water is released by operating the drain by hand, so it fits installations with a regular maintenance routine; automatic or differential-pressure drains are the catalogue alternatives for unattended setups. The L code marks the low-pressure regulator type, intended for circuits running below standard working pressures - confirm the exact adjustment band with us, as it is not published in the standard range tables.
