The AirTAC GFR30015MLC2WK 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 GFR30015MLC2WK is an AirTAC GFR300 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This configuration is built with a 5 um filter element (the finer of the two published grades), a manual drain on the PC bowl, and a low-pressure regulator type, so it suits circuits where clean air is needed at reduced pressure rather than near full line pressure. It carries a PT1/2 (1/2 in) PT-thread port, a round pressure gauge with psi scale, a reverse/check valve, and a mounting bracket. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR300 size sits in the GFR range that spans sizes 200, 300, 400 and 600, with a choice of port sizes, PT, G or NPT threads, differential-pressure, automatic or manual drains, 40 um or 5 um elements, and gauge styles and scales. Flow figures for this series are published as curves rather than a single rated number, so ask us and we will 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

Fixture clamps and swing cylinders on a machining or assembly cell run best at a set, reduced pressure. This unit filters the shop air to 5 um, regulates it down with the low-pressure type regulator, and the fitted check valve helps hold the downstream setting if upstream supply dips.
Carton formers, case sealers and labeler cylinders on packaging lines need clean, regulated air at a moderate pressure. A PT1/2 filter regulator at the machine inlet conditions the supply in one body, with the round psi gauge letting operators read and verify the set point at a glance.
Test rigs and lab benches that feed pneumatic instruments or sample-handling actuators need particulate-free air at a controlled low pressure. The 5 um element, manual drain bowl and low-pressure regulation make this unit a tidy single-connection conditioning point, with the included bracket for panel or frame mounting.
Start with the port step: this unit is the 300 size with a PT1/2 (1/2 in) PT-thread connection, so match it to your line size and the flow your circuit needs - and because flow for this series is published as curves, not a single rating, ask us to confirm sizing against your application before ordering. This unit is the low-pressure regulator type; its exact regulation range is not published in the standard tables, so confirm the set pressure you need with us first. It uses a manual drain, which means an operator opens the bowl drain periodically; if you would rather not rely on manual attention, the same family is available with automatic or differential-pressure drains. The 5 um element (code W) is the finer option versus the 40 um standard - choose it when downstream equipment needs cleaner air. Gauge scale here is psi on a round external gauge; square embedded gauges and MPa or bar scales are alternatives in the family. PT is the standard thread; G (BSPP) and NPT are order options. A mounting bracket is included.
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 number, so we do not quote a figure here. Send us your application details - line pressure, downstream demand and acceptable pressure drop - and we will confirm the datasheet flow curves and check the sizing for you before you order.
M in the code is the manual drain: an operator periodically opens the bowl drain to release collected water, which suits attended installations. W is the 5 um filter element - the finer grade compared with the 40 um standard element. If you prefer unattended water removal, the same GFR300 family is available with automatic or differential-pressure drains.
