The AirTAC GFR30010LC2T AirTAC Filter Regulator NPT3/8 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 GFR30010LC2T is a 300-size filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is the low-pressure type, fitted with an external round gauge scaled in psi, a 40 um standard filter element, and a differential-pressure drain that bleeds accumulated condensate automatically as the pressure differential across the bowl changes. The 3/8 in NPT port suits medium-flow circuits, the polycarbonate bowl gives a clear view of condensate level, and a mounting bracket is included for secure panel or frame fixing.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port options, thread choices (PT standard, G and NPT to order), drain types, 40 um or 5 um filter grades, gauge styles and scales. 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 we confirm the datasheet figures for your application 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. 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.

On an assembly fixture where clamps must close at a gentle, repeatable pressure, this filter regulator cleans the plant air supply and holds the reduced setting, with the psi gauge giving the operator a direct read of the clamp circuit.
Spray guns and atomising lines are sensitive to dirt and pressure drift. This unit filters water and particulate from the shop air and regulates it to the low setting the booth requires, with the differential-pressure drain keeping condensate out of the finish.
On a carton-sealing or wrapping line with 3/8 in air drops, this filter regulator conditions the supply to the machine's valve block, protecting cylinders and seals while the included bracket mounts the unit beside the machine's air inlet.
Start with size and port: the 300 frame with its 3/8 in NPT port is the middle step in the GFR range, so step up to 400 or 600 for larger circuits and down to 200 for compact ones, matching the size against the flow your line needs. This unit is the low-pressure type, chosen where the regulated pressure sits well below the standard range; its exact adjustment range is not published, so ask us to confirm it against your setpoint before ordering. The 40 um element is the standard grade and suits general plant air; specify the W code for the 5 um option if downstream equipment needs finer filtration. The differential-pressure drain is the default and needs no daily attention; if you prefer positive control, a manual-drain variant exists in the family. The round gauge here is scaled in psi; square embedded gauges and MPa or bar scales are alternatives. PT is the standard thread, with G and NPT as order options, and a 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 that is not in the datasheet. Send us your application details and we will confirm the flow figures from the datasheet on request, so you can size the 300 frame against your line before ordering.
This unit is the L-code low-pressure version of the GFR300, intended for circuits where the regulated pressure sits below what the standard type is set up for. Its exact adjustment range is not published in the material we hold, so we confirm it on request against your setpoint. As context for the family, standard GFR units with differential-pressure drains adjust over 0.15-0.9 MPa (20-130 psi) and manual-drain versions over 0.05-0.9 MPa (7-130 psi).
