The AirTAC GFR30015MC2WT AirTAC Filter Regulator NPT1/2, 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR30015MC2WT is a 300-size filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has 1/2 in NPT ports, a 5 um filter element for finer filtration than the standard 40 um grade, a manual drain bowl, and a round pressure gauge reading in psi. The polycarbonate bowl is rated to a maximum inlet pressure of 1.0 MPa (145 psi), the standard regulator covers an adjustment range of 0.05-0.9 MPa (7-130 psi), and the unit operates in temperatures from -5 to 70 C (non-freezing). A mounting bracket is included.
This is a genuine AirTAC part from the GFR300 series. The GFR family is available in sizes 200, 300, 400 and 600 with a choice of drain type, filter grade, gauge style and scale, thread option and bracket arrangement, so a matching unit can be specified for most line sizes. Because flow is published as curves rather than a single rated figure, we confirm the datasheet and sizing figures for your application 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. Standard type, regulating 0.05 - 0.9 MPa (7 - 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.

|---|---|
| 15 | Port size PT1/2". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 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 clamping and tool-change circuits of a CNC machining centre, with the 5 um element guarding precision valves from fine particulate.
Supplies regulated air to the cylinders and vacuum generators on a carton-sealing conveyor, keeping actuator speed stable as upstream pressure fluctuates.
Prepares air at the drop for impact wrenches and sanders in a body shop, with the manual drain letting the operator bleed accumulated water at shift start.
Start with the port size: this unit steps up to 1/2 in NPT within the 300 series, and larger sizes (400, 600) carry more flow if your line demands it. Choose the drain to suit access: manual drain (as here) needs an operator to bleed the bowl, automatic drain handles condensate unattended, and the differential-pressure default suits standard duty. Pick the filter grade for the job: 40 um is the standard element, while the 5 um grade (code W, fitted here) protects finer downstream components. Gauge style and scale are selectable - embedded square or external round, in MPa, psi or bar (this unit: round, psi). Thread is PT as standard with G and NPT as order options, and a bracket is included unless the J code omits it.
Flow for this family is published as curves, not a single rated number, so please 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 flow for this family as curves rather than a single rated figure, so we do not quote a number. Tell us your line size and demand and we will confirm the flow and sizing from the datasheet on request before you order.
The M code in the model specifies a manual drain bowl: an operator opens the drain to release collected condensate. It suits installations that are checked regularly. If the unit will sit unattended, specify the automatic drain (code A) or the differential-pressure default instead.
