The AirTAC GFR200-08L AirTAC Filter Regulator, NPT1/4, 5 um 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 differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR200-08L is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single 200-size body with 1/4 in NPT ports. This configuration is the low-pressure type, so it is intended for circuits where the working pressure sits below what a standard regulator is set up for; the exact regulation range for the low-pressure type is not published, and we confirm it on request. It carries a 5 um filter element (code W), a differential-pressure drain that bleeds accumulated condensate automatically whenever the pressure differential across the element is high enough, a round external gauge scaled in psi, and a built-in reverse/check valve that holds the downstream setting if upstream pressure is lost. No mounting bracket is included with this code.
This is a genuine AirTAC part. The GFR family spans 200, 300, 400 and 600 sizes with port options from 1/8 in to 1 in, PT as the standard thread and G or NPT as order options, plus choices of drain type, filter grade, gauge style and scale. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |

| C | Gauge shape: Round. 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. |
| T | NPT 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.

On a machining-cell fixture that clamps workpieces at reduced air pressure, this unit filters the shop air to 5 um and holds a low regulated setting, with the check valve keeping the clamp from releasing if supply pressure drops.
A lab test rig running instruments and small actuators on clean, low-pressure air gets particulate and water removal plus fine regulation from one body, with the psi gauge giving a direct local reading at the bench.
On a packaging conveyor where low-pressure air drives diverters and hold-down cylinders, this filter regulator protects the actuators from water and 5 um-level particles while the differential-pressure drain keeps condensate moving out.
Start with size and port: the 200 size with 1/4 in NPT ports suits compact circuits, and stepping up to 300/400/600 increases both port size and flow capacity - match the step to the flow your line needs. Then choose the drain: differential-pressure (this unit) drains on pressure differential, automatic drains on a timed/floating principle, and manual requires someone to open the drain; on a low-pressure circuit, confirm with us which behaviour fits. Filter grade is 40 um standard or 5 um (code W, fitted here) where finer particulate removal matters. Gauge choices are the embedded square type or an external round gauge, scaled in MPa, psi or bar - this unit has a round psi gauge. Threads are PT as standard with G (BSPP) and NPT as order options; brackets are optional (this code has none).
One honest note on sizing: AirTAC publishes flow as curves, not a single rated number, so we cannot quote a rated flow here. Send us your application details and we will confirm the datasheet figures and correct size 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 this family as curves, not as a single rated figure, so we do not quote a rated flow number. Send us your application details - required flow, working pressure and port size - and we will confirm the datasheet curves and check the sizing with you before you order.
The L in this code marks the low-pressure regulator type, intended for circuits where the regulated working pressure is lower than the standard type is set up for. The exact regulation range for the low-pressure type is not published, so we confirm it on request; the standard type is the choice where normal-range regulation is needed. Everything else in this unit - 1/4 in NPT ports, 5 um element, differential-pressure drain, round psi gauge and check valve - is unchanged.
