The AirTAC AirTAC GFR600C25MLC2WG Filter Regulator G1 Low-Pressure 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 See datasheet 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 GFR600C25MLC2WG is an AirTAC GFR-series filter regulator: a single body that removes water and particulate from compressed air and regulates the downstream pressure. This unit is built on the size-600 frame with a G1 (1 in) port in G (BSPP) thread, the low-pressure regulator type, a 5 um filter element (code W), a manual drain on the bowl, a round gauge reading in psi, and a mounting bracket included. At size 600 the bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, drain choices (differential-pressure, automatic or manual), 40 um standard or 5 um filtration, gauge and scale options, and PT, G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi) and the working 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. 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.

Filtered, regulated air to fixture and clamp cylinders that must close at reduced pressure so delicate workpieces are held without crushing. The 5 um element protects the clamp valves from water and swarf carryover.
Conditioned air for spray guns and low-pressure atomizing lines in a coating booth, where the regulator is set below standard plant pressure and the filter keeps oil-free, dry air reaching the gun.
Regulated low-pressure air driving adhesive applicator valves and coating heads, with the 5 um grade guarding the small metering components and the manual drain fitted to a maintenance-accessible spot.
Size up by the port and flow step: size 600 with its 1 in port is the largest GFR frame, so step down to 400, 300 or 200 if your line draws less air. If your process needs lower regulated pressures than a standard regulator delivers, the L (low-pressure) type in this code is the relevant choice - confirm the exact range with us before ordering. The manual drain here means someone drains the bowl on a schedule; automatic or differential-pressure drains are available on other codes if that does not suit your maintenance routine. The 5 um element (W) gives finer protection than the 40 um standard. The round gauge on this unit reads psi; the embedded square gauge and MPa or bar scales are the other options. G (BSPP) thread is an order option against the PT standard, and NPT is also available. A mounting bracket is included. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before you order.
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 flow for the GFR series as curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure, downstream demand and allowable pressure drop and we will confirm the sizing from the datasheet on request.
The L code marks the low-pressure regulator variant, intended for applications regulated below what the standard type targets; the exact range is not published in the material we hold, so confirm it with us. The M code is the manual drain: the bowl is emptied by hand on a schedule, whereas automatic and differential-pressure drains are available on other codes in the same series.
