The AirTAC GFR60025LF2WG AirTAC Filter Regulator G1 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" 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 GFR60025LF2WG is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure at a set point, in one body. This size-600 configuration carries a G1 (1 in) G-thread port, a differential-pressure drain, a 5 um filter element (code W), the low-pressure regulator type, and a factory-fitted embedded square gauge reading in psi. The bowl on this 600 frame is aluminium alloy, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in up to 1 in, differential-pressure, automatic or manual drain choices, 40 um standard or 5 um (W) filtration, and MPa, psi or bar gauge scales. Max working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing. 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.

| F | Gauge shape: Square. C is round, F is square. |

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.

Installed on the 1 in main drop leaving a plant compressor room, this filter regulator conditions the whole distribution header: water and particulate are stripped out and the header pressure is set once at a single point for the downstream network.
Large diaphragm-actuated process valves on a water or wastewater treatment skid need clean air held at a modest set point. This low-pressure filter regulator feeds the actuation manifold, with the 5 um element protecting the positioner and pilot components.
On a food-packaging conveyor line, cylinder-driven pushers and diverters draw from a filtered, regulated branch. This unit supplies that branch, with the 5 um grade helping protect cylinder seals and the square psi gauge giving operators a visible set point.
Size and port are the first decodable choices: this unit is the top of the GFR range, size 600 with a G1 (1 in) G-thread port, so match it against the air demand of your main line. Because AirTAC publishes flow as curves rather than a single rated figure, send us your flow and pressure conditions and we will confirm sizing from the datasheet before you order. The L code selects the low-pressure regulator type, intended for circuits regulated at lower pressures; the exact adjustment window for this variant is not published, so confirm it with us. Remaining choices on this family are the drain (differential-pressure here, with automatic or manual available), the filter grade (5 um here versus the 40 um standard), the gauge scale (psi here; MPa or bar also offered), and the thread (G here; PT is the standard and NPT is an order option). A mounting bracket is included.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes GFR600 flow as curves rather than a single rated figure, so we do not quote a number here. Send us your flow and upstream/downstream pressure conditions and we will confirm the datasheet curve for your application before you order.
The W code in this model fits a 5 um element instead of the standard 40 um one, giving finer particulate removal ahead of sensitive downstream devices such as pilots, positioners and precision cylinders. It is a decode choice on the same body; for general plant air where coarser protection is sufficient, the 40 um standard grade is available across the same GFR series.
