The AirTAC GFR30015MJC2WT 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 GFR30015MJC2WT 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 a 1/2 in NPT port, a manual drain bowl in PC (polycarbonate), a fine 5 um filter element, and an external round gauge with a psi scale. The standard regulator covers 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 range is offered in sizes 200, 300, 400 and 600 with a choice of ports, PT/G/NPT threads, differential-pressure, automatic or manual drains, 40 um or 5 um elements, gauge styles and scales, and bracket options. Flow is published as curves rather than a single rating, so we confirm flow and datasheet figures 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. |
| J | Supplied without bracket. |

| 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. |

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 filtration and regulation for the pneumatic cylinders and grippers on a carton-forming and sealing line, with the 5 um element protecting valve spools from particulate and condensed water.
Regulated air for the pop-up gates and diverters on a distribution conveyor, where the manual drain bowl is bled during scheduled shift checks and the psi gauge gives operators a visible set point.
Clean, stable supply for the actuated valves and sample-handling modules of a laboratory automation bench, where the fine 5 um grade and precise low-end regulation support repeatable motion.
Size and port set the flow path: 300 size with a 1/2 in NPT port suits lines running above 3/8 in. Choose the drain to match maintenance access: this unit uses a manual drain, which needs periodic bleeding but allows regulation from 0.05-0.9 MPa (7-130 psi); automatic and differential-pressure drains raise the minimum set point to 0.15-0.9 MPa (20-130 psi). The 5 um element (code W) is the finer option versus the 40 um standard - pick it when downstream valves and cylinders need cleaner air. The round psi gauge is fitted here; embedded square gauges and MPa/bar scales are alternatives. Thread is NPT in this code; PT is the catalogue standard and G (BSPP) is also orderable. A bracket is not included in this configuration (code J) but is available. 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 number here. Tell us your line pressure, set pressure and air demand and we will confirm the flow and datasheet figures for this 300-size, 1/2 in NPT unit on request before you order.
The M in the code selects a manual drain bowl, which you bleed periodically instead of relying on an automatic mechanism. With a manual drain the standard regulator adjusts from 0.05-0.9 MPa (7-130 psi); with automatic or differential-pressure drains the minimum setting is 0.15-0.9 MPa (20-130 psi). The bowl is PC (polycarbonate) at this size, so keep the medium non-freezing within -5 to 70 C.
