The AirTAC GFR30015MC2WK 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 GFR30015MC2WK is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This 300-size unit is configured with a PT1/2 port, a 5 um filter element for finer filtration than the standard 40 um grade, a manual drain for the PC bowl, and a reverse/check valve fitted. The standard regulator covers 0.05-0.9 MPa (7-130 psi), and the psi round gauge is fitted for direct setting and monitoring.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port options from 1/8 to 1 inch, a choice of manual, automatic or differential-pressure drains, 40 um or 5 um filtration, gauge scale options and G/NPT thread variants. 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.

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 for a workshop press circuit: the 5 um element protects directional valves from fine particulate and condensate, while the regulator holds a stable set pressure stroke to stroke and the check valve holds the setting if upstream supply dips.
Feeding cylinders and grippers on a packaging or cartoning line, where consistent regulated pressure keeps cycle repeatability and the manual drain suits a machine tended at every shift.
Supplying pneumatic quarter-turn valve actuators on a process skid: the 5 um grade guards positioner and solenoid internals, the psi gauge gives operators a local pressure reading, and the check valve prevents backflow through the unit.
Size and port set the air capacity: 300 size with a PT1/2 port suits lines running heavier actuator and tool loads than 200/1/4-inch units, but sizing should be checked against required flow. This unit pairs a 5 um element (choose it over the 40 um standard where finer protection matters) with a manual drain - simple and reliable where an operator can bleed the bowl routinely; choose automatic or differential-pressure drain where the unit is hard to reach. The round psi gauge is fitted; MPa and bar scales are alternatives, and an embedded square gauge is the standard option. Thread is PT as standard, with G (BSPP) and NPT available to order; the mounting 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. 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 l/min, m3/h or SCFM number. Send us your application details and we will confirm the flow and datasheet figures for the GFR300-15 against your requirement before you order.
This unit's bowl has a manual drain: an operator opens it to bleed accumulated condensate. It is a simple, dependable choice when the unit is accessible and checked routinely. If the unit will be mounted where regular attention is impractical, ask about the automatic or differential-pressure drain variants of the same series.
