The AirTAC GFR30015MF2 AirTAC Filter Regulator PT1/2, 40 um 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 GFR30015MF2 is a size-300 filter regulator: it removes water and particulate from compressed air and sets downstream pressure in a single body. This configuration carries a PT1/2 port, a 40 um standard filtration element, a manual drain on the PC (polycarbonate) bowl, an embedded square gauge reading in psi, and a mounting bracket. The standard-type regulator covers an adjustment range of 0.05-0.9 MPa (7-130 psi), and the unit handles a maximum inlet pressure of 1.0 MPa (145 psi) at temperatures from -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR filter-regulator line is available in sizes 200, 300, 400 and 600 with port options from 1/8 to 1 inch, a choice of manual, automatic or differential-pressure drains, a 5 um element option, gauge scales in MPa, psi or bar, and G or NPT thread variants to order. Because flow is published as curves rather than a single rating, we confirm flow and datasheet figures on request before you order.

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.

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.

Feeding filtered, regulated air to a bench or pneumatic press on a 1/2 in main, with the manual drain cleared as part of the shift-start routine.
Conditioning the air supply to carton-sealing and case-erector cylinders, where clean, dry air at a stable setpoint keeps stroke timing consistent.
Serving as the point-of-use filter regulator at an assembly-cell air drop, protecting downstream valves and cylinders from water and pipe scale.
Size and port are the first choice: the 300 size with its PT1/2 port suits lines where a 1/2 in air main feeds the unit, and larger sizes carry larger ports and higher flow capacity. For this model the drain is manual, so plan a routine blow-down; if the installation is hard to reach, an automatic or differential-pressure drain variant may suit better. The 40 um element is the standard grade for general plant air, while the 5 um (W) option is there when finer particulate removal is needed. The embedded square gauge here reads psi; MPa and bar scales and an external round gauge are alternatives. Thread is PT as standard, with G (BSPP) and NPT available as order options, and the bracket is included.
Flow for this family is published as curves, not as a single rated figure, so ask us to confirm sizing against your application and the datasheet 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 performance curves rather than a single rated figure, so we do not quote a rated flow number. Send us your application details and we will confirm the sizing and the relevant datasheet figures on request before you order.
The M in GFR30015MF2 specifies a manual drain, which means condensate is released by operating the drain by hand on a planned schedule. The GFR family also offers automatic (code A) and differential-pressure (blank) drains for installations where manual blow-down is impractical; the drain choice also affects the regulator adjustment range, with manual-drain units covering 0.05-0.9 MPa (7-130 psi).
