The AirTAC GFR30010LF2TK AirTAC Filter Regulator 3/8 in NPT 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 GFR30010LF2TK is an AirTAC GFR300 filter regulator: one body that removes water and particulate from compressed air and regulates the downstream pressure. This configuration is the size 300 unit with a 3/8 in NPT port, the standard 40 um filter element, and a differential-pressure drain that discharges collected condensate automatically. The regulator is the low-pressure type, an embedded square gauge reading in psi is fitted, a reverse/check valve holds the downstream setting if the upstream supply dips, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options include a 5 um filter element (code W), automatic or manual drains, gauge scales in MPa, psi or bar, and G (BSPP) or NPT threads in place of the PT standard. 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 ask us to confirm sizing and 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 clamp cylinders on a machining fixture where full line pressure would deform or mark the workpiece. The low-pressure regulator type, the psi-reading square gauge and the 40 um element protecting the clamping valve make this a single-unit supply point.
A bench setup that needs clean, gently regulated air to instruments or small actuators. The reverse/check valve holds the set pressure if the shop supply dips, and the differential-pressure drain keeps condensate out of sensitive equipment without daily attention.
A filter regulator ahead of the small cylinders and actuators on a packaging line: water and particulate are stripped out before they reach the valves, pressure is set low for delicate product handling, and the psi gauge lets the line technician verify the setting at a glance.
Size 300 with a 3/8 in port is the mid step in the GFR range; step up to size 400 or 600, or down to 200, as your air demand requires - we will confirm the flow curve against your consumption before you order. The drain here is differential-pressure (the default); automatic (code A) and manual (code M) versions exist if you prefer a set-and-forget or a hands-on drain. The 40 um element is standard; specify the W suffix for the 5 um grade where finer protection is needed. The fitted square gauge reads in psi; an external round gauge is optional, with MPa, psi or bar scales. This unit is ordered with an NPT thread (PT is the AirTAC standard, G/BSPP is also available as an order option), the low-pressure regulator type is selected by the L code, and the mounting bracket is included.
One honest note: AirTAC publishes flow 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR300 as curves, not as a single rated figure, so we do not quote a number on the page. Tell us your working pressure and air consumption and we will confirm the sizing from the datasheet on request before you order.
It selects the low-pressure regulator type instead of the standard one. The exact regulation range for the low-pressure type is not published in the catalogue, so ask us to confirm it from the datasheet for your setpoint. Maximum inlet pressure is still 1.0 MPa (145 psi).
