The AirTAC GFR200-08 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 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 GFR200-08 is a 200-size filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is the low-pressure type with a 5 um filter element (code W), a manual drain on the PC bowl, a built-in square gauge scaled in MPa, and a 1/4 in NPT port. It is the version to pick when the line runs at low set pressures and the element must catch finer particles than the standard 40 um grade. The bowl is polycarbonate (size 200 is PC; only size 600 uses aluminium alloy), maximum inlet pressure is 1.0 MPa (145 psi), and the working temperature range is -5 to 70 C, non-freezing. No mounting bracket is included with this code; a bracket is available as an option.
This is a genuine AirTAC part. The GFR family runs from size 200 to 600 with port sizes from 1/8 in to 1 in, in PT (standard), G and NPT threads, with differential-pressure, automatic or manual drains, 40 um or 5 um elements, standard or low-pressure regulation, and square or external round gauges in MPa, psi or bar scales. 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. |
| 1 | Gauge scale: MPa. 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. |
| (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 clean, finely filtered air to pneumatic clamps and hold-downs that work at low set pressures, with the square MPa gauge giving the operator a direct read of the regulated line.
Supplies filtered, regulated air to the small cylinders that fold flaps and press cartons, where the 5 um element helps keep directional valves and cylinders free of fine debris.
Gives bench-scale rigs a single point of fine-particle filtration and low-pressure regulation for air to instruments and actuators, with manual drain suited to supervised, intermittent use.
Start with the port step: the 200 size here carries a 1/4 in port, and the family steps up through 300, 400 and 600 as flow demand grows. Because flow is published as curves and not as a single rated number, tell us your application and we will confirm sizing against the datasheet before you order. This unit is the low-pressure type, chosen where set pressures sit below the standard range; the exact regulation range for this variant is not published in the catalogue, so confirm it with us. The 5 um element (code W) suits lines that need finer filtration than the standard 40 um grade. The manual drain means someone drains the bowl periodically; the family also offers automatic and differential-pressure drains if you prefer not to. The square gauge fitted here reads in MPa; psi and bar scales and an external round gauge are options. Threads are PT as standard, with G and NPT as order options - this code is NPT. A mounting bracket is optional; this code ships without one.
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 flow for the GFR series as curves, not as a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow figures from the datasheet and check the sizing against your demand before you order.
This code carries M, the manual drain: the PC bowl is emptied by hand at intervals you set. The GFR family also offers an automatic drain (code A) and a differential-pressure drain (blank), which suit unattended installations. All three are catalogue options on the same filter regulator.
