The AirTAC GFR30008LC2G AirTAC Filter Regulator, Low-Pressure, G1/4 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 GFR30008LC2G is an AirTAC GFR300 filter regulator: filtration and pressure regulation combined in a single body. It removes water and particulate from compressed air with the standard 40 um element, then regulates downstream pressure, and this unit is the low-pressure type for applications supplied at reduced pressure. It is configured with a G1/4 (BSPP) port, differential-pressure drain, an external round gauge reading in psi, and a mounting bracket included. The polycarbonate bowl suits the 300 size, with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating temperature of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with matching port sizes, a choice of differential-pressure, automatic or manual drain, a 5 um (code W) filter element option, embedded square or external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow figures are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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.

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.

Supplies filtered, low-pressure air to clamp and unclamp workholding fixtures on a CNC machining cell, keeping chips and condensed water out of the clamp cylinders while holding a reduced set pressure.
Feeds clean, regulated air to the blow-off jets and diverter actuators on a packaging conveyor, where the low-pressure type matches circuits that run below full line pressure.
Conditions the compressed air feeding lab benches and pilot-scale process equipment, removing water and 40 um particulate and trimming pressure down to the reduced level the instruments require.
Start with the size and port: this unit is a 300 with a G1/4 port, one step in the 200/300/400/600 range where larger sizes carry larger ports and higher flow capacity. Because this is the low-pressure (L) type, choose it where the downstream circuit runs at reduced pressure; the exact regulation range for the low-pressure type is not published, so confirm it with us against your set pressure before ordering. Drain options are differential-pressure (this unit, default), automatic (code A) or manual (code M). Filter grade is 40 um standard here, with 5 um (code W) available where finer filtration is needed. Gauge choice is the fitted round psi gauge on this code, or an embedded square gauge in MPa, psi or bar scales. Thread is G (BSPP) on this code; PT is the standard thread and G or NPT are order options. A bracket is included.
Flow is published as curves, not a single rated figure, so send us your application details and we will confirm sizing 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, not as a single rated figure, so we do not quote a l/min, m3/h or SCFM number. Send us your application details and we will confirm the flow data from the datasheet and check the sizing against your requirement before you order.
The L in GFR30008LC2G marks the low-pressure regulator type, intended for circuits supplied at reduced pressure rather than the standard version. The exact regulation range for the low-pressure type is not published in the catalogue, so confirm your set pressure with us and we will verify suitability from the datasheet. Everything else on this code decodes normally: 300 size, G1/4 port, 40 um filter, differential-pressure drain, round psi gauge and G thread.
