The AirTAC GFR30015MLC2W 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 GFR30015MLC2W 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 PT1/2 (1/2 in) port, a fine 5 um filter element (the W grade, tighter than the standard 40 um), and a manual drain you operate by hand to clear collected condensate from the PC bowl. It is the low-pressure regulator type, and a round external gauge reading in psi is fitted so the setpoint is visible at a glance. A mounting bracket is included.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, thread options PT (standard), G and NPT, drain and filter-grade choices, and gauge variants. Flow is published as curves rather than a single rating, so ask us to confirm sizing or any datasheet figure against your application before ordering.

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.

On a CNC fixture line using low-pressure clamping cylinders, this unit filters the shop air to 5 um and holds a gentle, visible setpoint so workpieces are secured without crushing, with the psi gauge letting the setter verify the clamp circuit at a glance.
Feeding spray guns in an automotive refinish booth, the 5 um element strips water and particulate that would otherwise blemish the finish, while the low-pressure regulator sets the gentle gun supply pressure indicated on the round psi gauge.
On a carton-forming packaging machine running low-pressure air actuators, this filter regulator cleans the supply and keeps the actuation pressure steady, with the manual drain cleared during shift checks and the included bracket fixing the unit to the machine frame.
Choose the size and port step against the air demand of the circuit: this unit is size 300 with a PT1/2 port, one step up from 1/4 in and 3/8 in sizes in the same series. The 5 um element (code W) suits downstream equipment that needs cleaner air than the 40 um standard grade delivers. The manual drain suits installations where an operator can bleed the bowl periodically; if the unit will run unattended, ask about automatic or differential-pressure drain variants. The round psi gauge is fitted here; embedded square gauges and MPa or bar scales are alternatives. Thread is PT as standard, with G (BSPP) and NPT available to order, and the bracket is included.
Because flow is published as curves rather than one rated figure, and this is the low-pressure regulator type whose exact adjustment range is not published in the standard table, ask us to confirm sizing and the operating range 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 flow for this series as curves, not as a single rated number, so we do not quote a figure here. Tell us your application and we will confirm the flow and sizing from the datasheet on request before you order.
The M in the code selects the manual drain: you open it by hand to discharge condensate from the PC bowl, which suits attended installations; automatic and differential-pressure drain variants exist for unattended duty. The W selects the 5 um filter element, one grade finer than the 40 um standard, for downstream equipment that needs cleaner air.
