The AirTAC GFR30015LF2W AirTAC Filter Regulator 1/2 in PT, 5 um is a genuine G-series filter regulator: water separation, 5 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 GFR30015LF2W is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size-300 unit has PT1/2 (1/2 in) ports with PT thread as standard, a 5 um filter element (the finer of the two published grades), and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element rises. It is the low-pressure regulator type and carries an embedded square gauge with a psi scale; a mounting bracket is included.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of drain types, 40 um or 5 um filtration, gauge scale options, and G or NPT thread variants to order. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures against 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.

| F | Gauge shape: Square. C is round, F is square. |

| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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.

Feeds filtered, regulated air to the cylinders of a bench or C-frame pneumatic press, where the 5 um element protects valve spools from particulate and the low-pressure regulator type suits circuits that run at reduced working pressure.
Supplies conditioned air to the pick-and-place cylinders and clamp actuators on a carton or blister packaging line, with the psi-scaled square gauge giving operators a direct local pressure readout at the machine.
Conditions the instrument-air supply to pneumatic ball and butterfly valve actuators on a process skid, where the differential-pressure drain keeps condensate off the positioner and the bracket allows panel mounting beside the valve manifold.
Choose the size and port step against the air demand of the circuit: this unit is size 300 with PT1/2 ports, one step up from the 1/4 in class. The 5 um element (code W) suits applications that need finer particulate capture than the 40 um standard; the differential-pressure drain suits lines with steady duty where automatic condensate bleeding is preferred over a manual drain valve. The low-pressure regulator type is selected where the working band sits below the standard regulator range - the exact adjustment range for this type is not published, so confirm it with us. The square gauge reads in psi; MPa and bar scales, an external round gauge, G (BSPP) or NPT threads, and bracket options are available across the family.
Because AirTAC publishes flow only as curves and not as a single rated number, we cannot quote a rated flow for this unit. Send us your application's flow and pressure requirements 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 flow for the GFR series as curves rather than a single rated figure, so no rated flow number can be quoted for this unit. Send us your required flow and working pressure and we will confirm sizing against the datasheet on request before you order.
The W code in GFR30015LF2W selects the 5 um filter element, the finer alternative to the 40 um standard, for better protection of downstream components. This unit is the low-pressure regulator type; the exact adjustment range for the low-pressure type is not published in the material we hold, so we will confirm it from the datasheet on request.
