The AirTAC GFR30015ALC2W AirTAC Filter Regulator PT1/2 5 um Auto Drain 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 automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR30015ALC2W is a 300-size filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built with a 1/2 in PT port, a fine 5 um filter element (code W), an automatic drain that expels collected condensate without manual attention, and a low-pressure regulator type for applications whose setpoints sit below the standard band. It carries a round pressure gauge reading in psi, and the reverse/check valve position is not fitted.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and can be ordered with manual, automatic or differential-pressure drains, 40 um or 5 um elements, embedded square or external round gauges in MPa, psi or bar scales, and G or NPT threads in place of the PT standard. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application.

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.

Feeding the actuator and gripper circuits of a carton-forming and sealing line, where the 5 um element protects directional valves from fine contamination and the low-pressure regulator holds a gentle setpoint for delicate clamping.
Conditioning shop air down to a stable low pressure for bench-top test rigs and sample-handling cylinders, with the psi gauge giving a direct readout and the automatic drain keeping the bowl clear between runs.
Supplying the air cylinders that divert trays on a packaging conveyor, where the low-pressure type regulator prevents over-pressurising lightweight actuators and the 5 um grade keeps moisture and grit out of the valve bank.
Start with the port step: this unit is 300 size with a 1/2 in PT port, one step up from 3/8 in and one below 3/4 in, so match it to the line size your flow actually demands rather than oversizing by habit. The 5 um element (W code) suits downstream equipment sensitive to finer particles; the 40 um standard element is the choice where only bulk water and coarse dirt matter. The automatic drain on this unit suits unattended or hard-to-reach installations; manual and differential-pressure drains are the alternatives on other codes. The round gauge here reads in psi; square embedded gauges and MPa or bar scales are order options. PT is the standard thread, with G (BSPP) and NPT available to order, and a mounting bracket is included.
Because AirTAC publishes flow as curves rather than a single rated figure, we do not quote a flow number here. Send us your application details and we will confirm sizing against the datasheet before you order.
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 the GFR300 series as curves, not as a single rated number, so we do not quote a figure here. Tell us your line pressure and the flow your equipment needs, and we will confirm the sizing against the datasheet on request.
The W code in the model sets the 5 um filter grade instead of the 40 um standard, for finer particulate protection, and the A code sets an automatic drain that discharges condensate on its own. If your installation is visited daily, a manual-drain code is the lower-maintenance-cost alternative; ask us to quote it.
