The AirTAC GFR30015MF2G AirTAC Filter Regulator G1/2, Manual Drain is a genuine G-series filter regulator: water separation, 40 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 GFR30015MF2G is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This 300-size unit is configured with a G1/2 (BSPP) port, a manual drain for emptying the bowl, the standard 40 um filter element, and the embedded square gauge scaled in psi. The standard regulator covers an adjustment range of 0.05-0.9 MPa (7-130 psi) with this manual-drain configuration, maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). The polycarbonate bowl and mounting bracket are included; no reverse/check valve is fitted.
This is a genuine AirTAC part from the GFR filter-regulator family, available in sizes 200, 300, 400 and 600 with port sizes from 1/8" to 1", manual, automatic or differential-pressure drains, a 5 um (code W) filter option, gauge scales in MPa, psi or bar, and G, NPT or PT threads. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and flow 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) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) 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.

Clean, regulated air feeding the cylinders of a bench or floor pneumatic press, with the square psi gauge giving the operator a direct setting reference at the machine.
Point-of-use preparation for a carton-sealing or wrapping machine, where the 40 um element protects directional valves and the regulator holds a stable supply pressure.
Supplying the air cylinders that raise diverters and stoppers on a distribution conveyor, with the manual-drain bowl emptied during scheduled line checks.
Size and port set the capacity: the 300 size with its 1/2" port suits mid-range air-preparation duties, while smaller 200 or larger 400/600 units step port and flow capacity up or down. Drain type is a real choice here: manual (as configured) needs periodic draining by hand, automatic drains continuously without attention, and the differential-pressure default drains when the pressure drop calls for it. Filter grade is 40 um standard or 5 um (code W) for finer protection. Gauge scale (MPa, psi or bar) and thread (PT standard, with G and NPT as order options) are also decodable choices, and the bracket is included.
Because flow is published as curves rather than 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. 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 one number. Send us your application details and we will confirm the datasheet and flow-curve figures for this 300-size, G1/2 unit on request.
This unit is configured with a manual drain: condensate collects in the polycarbonate bowl and is released by hand. Choose manual where the unit is accessible and checked routinely; choose automatic or differential-pressure drain codes if the installation is unattended. Note that the manual-drain configuration also allows a wider regulator adjustment range of 0.05-0.9 MPa (7-130 psi).
