The AirTAC GFR30015MC2W AirTAC Filter Regulator PT1/2 5 um 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 GFR30015MC2W is a 300-size filter regulator that removes water and particulate from compressed air and sets downstream pressure in a single body. This configuration is built around a 1/2 in PT port, a 5 um filter element (the finer of the two catalogue grades), and a manual drain, so condensate is released only when an operator opens the drain. Output pressure is adjusted across the 0.05-0.9 MPa (7-130 psi) range that applies to the manual-drain version, and a round gauge scaled in psi is fitted so the setpoint can be read directly. The polycarbonate bowl suits the 300 size, a mounting bracket is included, 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 family is published in 200, 300, 400 and 600 sizes with port sizes from 1/8 to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, gauge scale options, PT, G or NPT threads, and a low-pressure regulator variant. Air flow for GFR units is published as curves rather than a single rated figure, so we confirm the datasheet figures for your operating point 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 ahead of a CNC machine's pneumatic valves and clamps: the 5 um element keeps chips of scale and condensed water out of the machine's air circuit while the regulator holds a steady supply pressure for repeatable clamping.
Feeding pneumatic cylinders and diverters on a carton or case-packing conveyor, where the 1/2 in PT port matches the main drop line and the regulator lets each zone run at its own setpoint instead of full header pressure.
Installed at the wall drop of a factory work cell to knock water and pipe scale out of the compressed air supply before it reaches air tools, blow guns and small actuators, with the psi gauge giving operators a visible line pressure check.
Size up from the flow demand: the 300 size with its 1/2 in PT port sits in the middle of the GFR range, and stepping to 400 or 600 buys more flow capacity while 200 suits lighter duty. Choose the drain to match maintenance practice - manual (as here) for supervised installations, automatic or differential-pressure where the unit should clear condensate without attention. The 5 um element in this code is the finer option; the standard grade is 40 um if coarser protection is acceptable. Gauges are available embedded square or external round, scaled in MPa, psi or bar; this unit carries a round psi gauge. Thread is PT as standard, with G (BSPP) and NPT available as order options, and the included bracket simplifies panel or frame mounting. Because flow is published as curves rather than a single rating, 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 GFR performance as flow curves rather than a single rated figure, so we do not quote a l/min, m3/h or SCFM number for this unit. Tell us your inlet pressure, set pressure and expected demand and we will confirm the flow from the datasheet curve for your operating point on request.
A manual drain releases collected condensate only when opened, which suits supervised installations where someone checks the bowl routinely; automatic or differential-pressure drains suit unattended duty. The W code here selects the 5 um element, the finer of the two grades (the standard is 40 um), for better protection of downstream valves and actuators.
