The AirTAC GFR300C08MLF2WG AirTAC Filter Regulator G1/4, 5 um 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 GFR300C08MLF2WG is an AirTAC GFR300 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has G1/4 (BSPP) ports, a 5 um filter element (code W), a manual drain on the metal bowl, a low-pressure type regulator, an embedded square gauge with psi scale, and a mounting bracket included. The reverse/check valve is not fitted. Rated for a maximum inlet pressure of 1.0 MPa (145 psi) and -5 to 70 C (non-freezing).
This is a genuine AirTAC part in the GFR300 size family, which spans sizes 200 to 600 with ports from 1/8 in to 1 in and PT, G or NPT thread options. Flow for this series is published as curves rather than a single rating, so ask us to confirm sizing - and the exact low-pressure adjustment range - from the datasheet 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 for the pneumatic cylinders and grippers on a carton-forming packaging line: the 5 um element protects downstream valves, and the low-pressure regulator suits circuits that run below standard shop pressure.
Conditioning the pilot-air feed to pneumatically actuated process valves on a water-treatment skid: filtration plus regulation in one body keeps the pilot circuit clean and at a set pressure, with the manual drain emptied during routine rounds.
Supplying filtered, regulated air to clamping fixtures and air-powered tooling at a CNC machining cell: the square psi gauge gives a local pressure readout at the fixture, and the included bracket mounts the unit to the machine frame.
Decodable choices on this series: step up or down in size (200/300/400/600) to match the port and flow path you need; choose the drain - differential-pressure (default), automatic (A) or manual (M, as fitted here); pick the filter grade - 40 um standard or 5 um (W, as fitted here); select the gauge scale (MPa, psi or bar) with the embedded square gauge or an optional external round gauge; order PT, G or NPT thread; and add or omit the bracket. A low-pressure type (L) regulator is fitted on this unit.
Flow for this series is published as curves, not a single rated figure, so we cannot honestly quote one number. Send us your application details and we will confirm sizing - and the exact low-pressure adjustment range - from the datasheet before you order.
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 GFR300 series as curves rather than a single rated figure, so we do not quote one number. Tell us your application and we will confirm the flow data - and the low-pressure adjustment range - from the datasheet on request.
Code M on this model means a manual drain on the metal bowl, so condensate is emptied by hand during maintenance rounds. Automatic (A) and differential-pressure (blank) drains are decodable options on the GFR series - ask us to quote the variant you need.
