The AirTAC GFR30010LF2 AirTAC Filter Regulator PT3/8 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 PT3/8" 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 GFR30010LF2 is a size-300 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is the low-pressure type, fitted with a 40 um standard filter element, a differential-pressure drain that bleeds condensate automatically as flow passes through, an embedded square gauge scaled in psi, and a mounting bracket. The 3/8 in PT port suits medium-flow branch lines, and the polycarbonate bowl lets you see accumulated condensate at a glance.
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, thread options PT (standard), G and NPT, manual or automatic drain choices, a 5 um filter element option, and gauge scale options. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application before ordering.

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 air to clamp cylinders on a CNC fixture line where the clamping circuit runs at a deliberately low set pressure, with the gauge giving the operator a local psi reading.
Feeds pusher and divert cylinders on a packaging conveyor, combining water and particle removal with a gentle regulated supply so lightweight product handling stays consistent.
Conditions and regulates shop air feeding bench-top test rigs and pneumatic lab apparatus that operate at reduced pressures, with the 40 um element protecting sensitive downstream devices.
Size and port step up together: 200, 300, 400 and 600 cover 1/8 in through 1 in, so pick the size whose flow curve covers your demand at acceptable pressure drop - we can check the curve against your consumption on request. This unit is the low-pressure type, intended for lower set-pressure duties; the exact adjustment range for this variant is not published in the standard table, so confirm it with us for your set point. The 40 um element is the standard grade; specify the W option if you need 5 um filtration. Drain here is differential-pressure (the default); manual (M) and automatic (A) drains are orderable. The square gauge is fitted and scaled in psi (code 2); MPa or bar scales and an external round gauge are options. Thread is PT as standard - order G (BSPP) or T (NPT) if your piping needs them - and the bracket is included.
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 operating pressure and air consumption and we will confirm the datasheet curve and check the sizing against your application before you order.
The L in GFR30010LF2 marks the low-pressure regulator variant, intended for lower set-pressure duties than the standard type. The exact adjustment range for this variant is not published in the standard table, so confirm your target set pressure with us and we will verify it from the datasheet on request.
