The AirTAC GFR30008LF2 AirTAC Filter Regulator 1/4 in PT 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 PT1/4" 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 AirTAC GFR30008LF2 is a GFR-series filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This configuration is sized GFR300 with a 1/4 in PT port, carries the 40 um standard filter element and uses the differential-pressure drain. The L in the code marks the low-pressure regulator type, and F2 specifies the embedded square gauge with a psi scale. A mounting bracket is included, and the 300 size uses a polycarbonate bowl.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options for thread (PT standard; G and NPT to order), drain type, 5 um filtration (code W), gauge scale (MPa, psi or bar) and a reverse/check valve. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Because AirTAC publishes flow as curves rather than a single rating, we confirm flow and datasheet figures 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.

Filtered, low-pressure regulated air feeds swing clamps and work supports on a CNC fixture, keeping condensate and particles out of the clamp cylinders.
The 40 um element strips water and particulate ahead of the regulator, so paint guns and atomising air on a coating line receive clean, low-pressure regulated supply.
Clean, regulated air drives grippers and pushers on a packaging conveyor, with the psi square gauge letting operators set and check line pressure at a glance.
Choose the size by the port and flow step: this GFR300 carries a 1/4 in PT port, while sizes 400 and 600 step up to larger ports for higher demand. Drain is the differential-pressure type as coded, with automatic (A) and manual (M) drains orderable alternatives. Filtration is the 40 um standard element, with a 5 um element (W) when finer cleaning is needed. The square gauge here reads in psi; MPa and bar scales are 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, not a single rating, ask us to confirm sizing against your application before ordering.
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 GFR flow as curves rather than a single rated figure, so we do not quote one number. Tell us your application and we will confirm sizing and the datasheet figures on request.
With no drain letter in the code, this unit carries the differential-pressure drain, the standard choice for the GFR family. Automatic (A) and manual (M) drains are available as coded options if your application needs them.
