The AirTAC GFR30015JF1WT AirTAC Filter Regulator 1/2 in NPT, 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 AirTAC GFR300 series combines water and particulate filtration with pressure regulation in a single body, so one 1/2 in NPT connection both cleans the compressed air and holds a steady downstream setting. This configuration carries the 5 um element (code W) for finer particle removal than the standard 40 um grade, a differential-pressure drain that bleeds condensate automatically as flow passes through, an embedded square pressure gauge scaled in MPa, and no mounting bracket. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and the polycarbonate bowl suits the 300 frame.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and each size can be ordered with 40 um or 5 um filtration, differential-pressure, automatic or manual drain, PT (standard), G or NPT thread, and a square or round gauge in MPa, psi or bar scales. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). 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. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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 clean, regulated air to the tool-change clamping and pneumatic actuation circuits of a CNC mill, with the 5 um element guarding fine-tolerance valves on a 1/2 in main drop.
Conditions the air feeding conveyor diverters, bag sealers and case-erector cylinders on a packaging line, holding a stable regulator setting so cylinder strokes stay repeatable through the shift.
Placed ahead of spray-booth atomising and air-bearing equipment where the 5 um grade removes finer particles than the standard element, protecting finish quality on a production coating line.
Start with the port step: this unit is the 300 size with a 1/2 in NPT thread, one step up from 3/8 in and one below 3/4 in, so match it to the line size your air consumption actually needs rather than defaulting to the largest port. Choose the drain to suit access: differential-pressure (as fitted here) drains with flow, automatic drains regardless of flow, and manual suits supervised installations. Pick the element grade: 40 um for general protection, 5 um (this unit) where finer particles matter downstream. Select the gauge scale (MPa, psi or bar) and thread family (PT standard, G or NPT to order); brackets are optional on GFR.
One honest note on sizing: AirTAC publishes flow for this series as curves, not a single rated number, so we cannot quote a rated flow figure. Send us your application details and we will confirm the correct size and datasheet figures 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 GFR300 series as performance curves, not as a single rated figure, so we do not quote a rated flow, Cv or SCFM number for this unit. Tell us your application and line conditions and we will confirm the datasheet and check the sizing for you before you order.
The W in the code GFR30015JF1WT selects the optional 5 um filtration grade; the blank default is 40 um. Choose 5 um when downstream equipment such as precision valves, atomising nozzles or instruments needs finer particle removal. The drain on this unit is differential-pressure, and the regulator adjusts from 0.15-0.9 MPa (20-130 psi).
