The AirTAC GFR30015MLJC2WTK AirTAC Filter Regulator NPT1/2 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 GFR30015MLJC2WTK is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This 300-size unit is configured with a 1/2 inch NPT port, a 5 um filter element (the finer of the two catalogue grades), a manual drain for the PC bowl, and the low-pressure regulator type. A round external gauge scaled in psi is fitted, and a reverse/check valve is built in. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part from the GFR series, which spans sizes 200 to 600 with port sizes from 1/8 to 1 inch, a choice of 40 um or 5 um filtration, manual, automatic or differential-pressure drains, and gauge options. The exact regulation range of the low-pressure type is not published in our data, and flow is published as curves rather than a single rating - we confirm both from the datasheet 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.
| GFR300 | G-series filter regulator, 300 body — sets the port range. |
|---|---|
| 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)). |
| L | Low-pressure 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. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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.

Clean, regulated air for carton-sealing and wrapping machines on a packaging line, where the 5 um element protects directional valves and cylinders from particulate carryover and the low-pressure setting matches the machine's supply requirement.
Filtered, pressure-controlled air feed for blow-off nozzles along food or product conveyors, with the manual drain emptied during scheduled line cleaning and the psi gauge giving operators a visible setpoint.
A bench-mounted supply for pneumatic test rigs and laboratory apparatus that need finer 5 um filtration and gentle low-pressure regulation, with the check valve holding the set circuit when upstream supply fluctuates.
The 300 size with a 1/2 inch port sits mid-range in the GFR series; step up to 400 or 600 for larger air demand, or down to 200 for compact lines. The 5 um element (code W) suits applications more sensitive to particulate than the 40 um standard grade. The manual drain means an operator opens the bowl drain periodically - choose automatic or differential-pressure drain codes if you prefer unattended moisture removal. The fitted round gauge reads in psi; square embedded gauges and MPa or bar scales are the other catalogue options. The T suffix gives NPT thread; G (BSPP) and the PT standard are the alternatives to order. No mounting bracket is included with this code (J). Because flow is published only as curves, not a single rated figure, 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. The reflux valve permits reverse flow 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 number, so we do not quote a figure here. Tell us your application and we will confirm the flow data from the datasheet on request before you order.
The M in the code specifies a manual drain: the PC bowl is emptied by opening the drain when moisture collects. AirTAC also offers automatic (A) and differential-pressure (blank) drain versions of the same 300-size filter regulator if you want unattended drainage.
