The AirTAC GFR20008MLJF2WK AirTAC Filter Regulator PT1/4 Low-Pressure is a genuine G-series filter regulator: water separation, 5 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 GFR20008MLJF2WK is an AirTAC GFR200 filter regulator: filtration and pressure regulation combined in one body. It removes water and particulate from compressed air through a 5 um element and holds a set downstream pressure, with a manual drain on the PC bowl for periodic water removal. This configuration is the low-pressure type, carries a reverse/check valve, and is fitted with an embedded square gauge scaled in psi. The port is PT1/4 (1/4 in PT thread), maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, in PT, G or NPT thread, with differential-pressure, automatic or manual draining, a 40 um standard or 5 um (W) element, square or round gauges in MPa, psi or bar scales, and bracket options. Flow 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.

|---|---|
| 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. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT 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.

A packaging line running vacuum and air-assisted pick-and-place heads needs clean, moisture-reduced air held at a steady low setpoint. This filter regulator conditions the drop feeding those heads, with the psi gauge letting operators read the setting directly.
Actuated butterfly and ball valves on a treatment skid run on instrument air that must be free of water and grit and held at a controlled low pressure. This unit filters and regulates that supply in one body, with the check valve holding the downstream side if supply dips.
Bench-top analytical and test instruments fed from a shop-air header need fine filtration and a stable, low regulated pressure. The 5 um element and low-pressure regulation suit this duty, and the manual drain suits a supervised lab environment where someone drains the bowl on a schedule.
Size and port step up together: 200 through 600, with ports from 1/8 to 1 in, so pick the size whose flow curve covers your demand at working pressure. Drain choice matters: manual (this model) needs periodic draining by hand, automatic drains itself, and differential-pressure drains on a pressure drop. Filter grade is 40 um standard or 5 um with the W code (this model is 5 um). Gauges are embedded square as standard with an optional external round gauge, in MPa, psi or bar scale. Thread is PT as standard with G and NPT as order options, and the J code here means no mounting bracket.
Flow for this family is published as curves, not a single rated figure, so we cannot quote one number. Send us your application details and we will confirm sizing against the datasheet curves 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 flow for the GFR family as curves, not as a single rated number, so there is no one figure we can quote. Send us your line pressure, downstream demand and acceptable pressure drop, and we will confirm the sizing against the datasheet curves on request before you order.
The M code in the model means the PC bowl is drained by hand: an operator opens the drain periodically to remove collected water, which suits attended installations. The W code sets the filter element to 5 um instead of the 40 um standard, for finer particulate removal where downstream equipment needs cleaner air.
