The AirTAC GFR200-08 AirTAC Filter Regulator G1/4, 40 um, psi gauge 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 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 GFR200-08 is a size-200 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one compact body. This configuration has a G1/4 (BSPP) port, standard 40 um filtration, a differential-pressure drain that bleeds condensate automatically whenever the pressure drop across the element is high enough, and an embedded square gauge reading in psi. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating temperature of -5 to 70 C (non-freezing). The polycarbonate bowl keeps the bowl contents visible for inspection.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port options from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um (W) filtration, square or round gauges with MPa, psi or bar scales, and G or NPT thread alternatives to the PT standard. Flow is published in the catalogue as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures 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. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). 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.

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.

Point-of-use conditioning at an assembly-cell air drop: the 40 um element strips water and pipe scale from the header supply while the regulator holds a steady, lower pressure to the cell's tools and cylinders.
Feeding air to packaging-line conveyors, clampers and sealers, where the square psi gauge lets operators verify set pressure at a glance and the differential-pressure drain keeps condensate out of the valves below.
Conditioning bench air on laboratory or test rigs, where clean, particulate-free air and a stable, adjustable regulated pressure are needed for instruments and pneumatic fixtures.
Size 200 with a G1/4 port is the entry step of the GFR range; if your line needs more air, step up to size 300, 400 or 600, which carry larger ports and higher flow. This unit's differential-pressure drain suits installations where a regular manual blow-down is impractical; choose automatic (A) or manual (M) drain codes if your duty differs. The 40 um standard element is right for general plant air; specify the W code for 5 um when downstream equipment needs finer filtration. The square gauge here reads psi; MPa and bar scales are also available. Thread is G (BSPP) on this model - PT is the standard thread, with G and NPT as order options - and the J code means no mounting bracket is fitted (brackets are optional). Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application 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 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 relevant datasheet flow figures for size 200 at G1/4 on request before you order.
This GFR200-08 has no drain code letter, which means the differential-pressure drain: condensate collected in the polycarbonate bowl is discharged automatically whenever the pressure drop across the filter element rises high enough. If you prefer timed automatic draining or a simple manual drain, those are available as the A and M drain codes in the same series.
