The AirTAC GFR30015MC2K AirTAC Filter Regulator PT1/2, 1/2 in 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 GFR30015MC2K is a GFR300-series filter regulator: filtration and pressure regulation combined in a single body, with a 1/2 in PT threaded port. This configuration carries a manual drain on the bowl, the standard 40 um filter element, a fitted round pressure gauge reading in psi, and a built-in reverse (check) valve that holds downstream pressure if the upstream supply is lost. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator setpoint range for this manual-drain version is 0.05-0.9 MPa (7-130 psi), and the operating temperature range is -5 to 70 C (non-freezing). The bowl on this 300 size is polycarbonate (PC).
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with a choice of ports, drain types (manual, automatic or differential-pressure), a 5 um element option (code W), gauge scales in MPa, psi or bar, G (BSPP) and NPT thread options, and bracket choices. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing 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.

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 conditioning for a CNC machine tool's pneumatic actuators and clamps: the 40 um element removes water and particulate before the air reaches the machine, and the regulator holds a steady setpoint for consistent clamping.
Conditioning the air feeding conveyor diverters and carton-forming cylinders on a packaging line, where the check valve keeps the downstream circuit pressurised if the main supply dips.
A regulated, filtered drop at a plant maintenance bench supplying air tools, blow guns and test rigs, with the psi gauge giving the technician a direct readout at the point of use.
Size and port are the first choice: 200, 300, 400 and 600 step up in port and capacity, and this unit sits at 300 with a 1/2 in PT port. Drain type matters in practice - manual drain means an operator drains the bowl, while automatic and differential-pressure drains discharge condensate without intervention; this code is the manual version. Filter grade is 40 um standard here, with 5 um (code W) available where finer particulate capture is needed. The fitted round gauge reads in psi; square embedded gauges and MPa or bar scales are alternatives. Thread is PT as standard, with G (BSPP) and NPT as order options, and the mounting bracket is included with this code.
Because catalogue flow is published as curves rather than one rated number, ask us to confirm the flow and sizing figures 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 figure, so we do not quote a number here. Tell us your application and we will confirm the flow and sizing figures from the datasheet on request before you order.
The M in the code GFR30015MC2K specifies a manual drain: condensate collected in the bowl is released by hand, which suits installations that are checked regularly. Automatic (code A) and differential-pressure (blank) drains are available on the same series if you want condensate discharged without operator intervention.
