The AirTAC GFR30015MJC2W AirTAC Filter Regulator PT1/2, 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 GFR30015MJC2W is a size 300 filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a PT1/2 port, a 5 um filter element (finer than the 40 um standard), a manual drain on the PC bowl, a round external gauge scaled in psi, and no mounting bracket. The standard regulator covers an adjustment range of 0.05-0.9 MPa (7-130 psi) with manual drain, and the unit handles a maximum inlet pressure of 1.0 MPa (145 psi) at -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, a choice of 40 um or 5 um filtration, differential-pressure, automatic or manual drains, embedded square or external round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm the 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. 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. |
| J | Supplied without bracket. |
| (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. |
| (blank) | PT 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.

Point-of-use conditioning on a CNC machining centre: the 5 um element protects solenoid valves and air bearings from water and fine particulate, while the regulator holds a steady setting for clamping and tool-change circuits.
Clean, stable air for lab automation and sample-handling actuators, where the finer 5 um grade and a local psi gauge let technicians verify and adjust supply pressure at the bench without walking back to the plant room.
Conditioning and regulation for pneumatic diverters and pushers on a packaging conveyor line, with the manual drain bled during shift checks and the regulator set to the pressure the diverter cylinders were designed for.
Start with the port step: size 300 with a PT1/2 port suits lines plumbed at 1/2 inch; step up to size 400 or 600 if the circuit grows, or down to size 200 for smaller drops. Choose the drain to match maintenance access: this unit has a manual drain, which suits attended installations where an operator can bleed the bowl; pick automatic or differential-pressure drain where the unit is hard to reach. The 5 um element on this model is the finer option for sensitive downstream equipment; the 40 um standard grade suits general protection. The round gauge here reads in psi; square embedded gauges and MPa or bar scales are also available. PT is the standard thread, with G and NPT as order options, and brackets are optional (this model ships without one). Flow is published as curves, not a single rating, so 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 the GFR series as curves, not as a single rated figure, so we do not quote a l/min, m3/h or SCFM number. Tell us your application and we will confirm the relevant flow and datasheet figures on request before you order.
The M in the code means the PC bowl is drained by hand: an operator opens the drain during routine checks, which suits attended installations. If the unit will sit in an inaccessible position, order the automatic (A) or differential-pressure (blank) drain variant instead - the filtration and regulation performance are the same.
