The AirTAC GFR30015MF2WG AirTAC Filter Regulator G1/2 5 um Manual Drain 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 GFR30015MF2WG is a 300-size filter regulator that removes water and particulate from compressed air and sets downstream pressure in a single body. This configuration carries a G1/2 (BSPP) port, a 5 um filter element for finer filtration than the 40 um standard, a manual drain for the PC bowl, and an embedded square gauge scaled in psi. The standard regulator covers a 0.05-0.9 MPa (7-130 psi) setting range with a maximum inlet pressure of 1.0 MPa (145 psi), and the unit operates from -5 to 70 C in non-freezing conditions.
This is a genuine AirTAC part. The GFR series is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, a choice of manual, automatic or differential-pressure drains, 40 um or 5 um filtration, MPa, psi or bar gauge scales, and G or NPT thread options. Flow is published as curves rather than a single rating, so we confirm the datasheet 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). |
| F | Gauge shape: Square. 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. |
| G | G (BSPP) 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.

Supply filtered, regulated air to a machine-tool clamping circuit, holding the fixture pressure steady at the set point while the 5 um element keeps valve spools clear of water and fine particulate.
Feed the cylinder and valve bank group on a carton or blister packaging line, where one body handles air preparation and the manual drain is bled during scheduled changeover and cleaning.
Regulate the supply to diverter gates, stoppers and pusher cylinders along a conveyor system, with the psi gauge giving operators a local read of the line pressure at the drop.
Size the GFR300 by port and expected flow: the 300 size with a 1/2 inch port sits in the middle of the range, one step above the 200 size and below the 400 and 600. Because flow is published as curves rather than a single rated figure, ask us to confirm sizing against your air demand before ordering. The 5 um element in this code suits points of use that need cleaner air than the 40 um standard; choose manual drain when an operator can bleed the bowl on a routine, or specify automatic or differential-pressure drain codes where unattended draining matters. The square gauge here reads in psi; MPa and bar scales are also available. Thread is G (BSPP) on this unit, with PT standard and NPT available as order options, and a mounting bracket is included.
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 GFR300 series as curves rather than a single rated figure, so there is no one l/min or SCFM number we can quote. Send us your line pressure, set pressure and air demand and we will confirm the sizing from the datasheet on request.
The M in the code GFR30015MF2WG specifies a manual drain, meaning the PC bowl is bled by hand at intervals. If the unit will run unattended, the same 300-size filter regulator is available with an automatic (A) or differential-pressure (blank) drain code instead, with the corresponding setting range for the regulator.
