The AirTAC AirTAC GFR30015LC2 Filter Regulator PT1/2, 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 PT1/2" 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 GFR30015LC2 is a GFR300 filter regulator: one body that removes water and particulate from compressed air and regulates the pressure delivered downstream. This configuration has 1/2 in PT ports, the standard 40 um filter element, a differential-pressure drain and the low-pressure regulator type. A round gauge scaled in psi is fitted and the mounting bracket is included. The polycarbonate bowl shows collected condensate at a glance, and the unit is rated for a maximum inlet pressure of 1.0 MPa (145 psi) at -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR series spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and offers manual, automatic or differential-pressure drains, 40 um or 5 um (W) filtration, standard or low-pressure regulation, embedded square or external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. 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. 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.

Feeding spray guns on a woodshop finishing line: the 40 um element strips water and swarf from shop air, while the low-pressure regulator holds a steady, gentle setpoint at the guns and the psi gauge keeps it visible to the operator.
Supplying the clamp and flap-fold cylinders on a packaging conveyor: filtered, regulated air at each station, with the round psi gauge giving a clear setpoint readout and the included bracket simplifying machine-frame mounting.
Regulating air to actuated valves and fittings on a laboratory or pilot-plant skid, where the low-pressure regulator and 1/2 in PT connection suit larger low-setpoint circuits and the differential-pressure drain handles collected condensate.
Choose the size step (200/300/400/600) and port (here 1/2 in PT) against the flow your line needs - larger sizes carry larger ports and more flow. On this unit the drain is differential-pressure (the default), the element is the standard 40 um grade (5 um available as code W), and regulation is the low-pressure type; its exact adjustment range is not published, so confirm your setpoint with us if it is critical. The fitted gauge reads in psi, with embedded square gauges and MPa or bar scales as alternatives. Thread is PT as standard, with G (BSPP) and NPT as order options, and the bracket is included. Because flow is published as curves rather than a single rating, send us your application and we will confirm sizing against 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 filter-regulator flow as curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the datasheet flow curve and sizing for the GFR30015LC2 before you order.
The L marks the low-pressure regulator variant. Its exact adjustment range is not published in the catalogue, so confirm your setpoint with us before ordering. Everything else decodes as standard: PT1/2 ports, 40 um filter element, differential-pressure drain, polycarbonate bowl, a fitted round gauge scaled in psi and an included mounting bracket.
