The AirTAC GFR30015AC2 AirTAC Filter Regulator PT1/2 Auto Drain is a genuine G-series filter regulator: water separation, 40 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 GFR30015AC2 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 a PT1/2 (1/2 in) PT-threaded unit with an automatic drain that ejects collected condensate without manual attention, a 40 um standard filter element, and a round pressure gauge reading in psi. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), and the operating temperature range is -5 to 70 C (non-freezing). The polycarbonate bowl is fitted for visual condensate checks, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR range spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options include a 5 um filter element (code W), manual or differential-pressure drain, G (BSPP) or NPT threads, different gauge scales, and a reverse/check valve. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for 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. Standard type, regulating 0.15 - 0.9 MPa (20 - 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 feeding tool-change cylinders and clamping fixtures on a machining cell, where the automatic drain keeps condensate out of valves without operator attention.
Pressure-regulated, filtered air for carton-forming and case-sealing cylinders on a packaging conveyor, with the psi gauge giving operators a local setpoint check.
Water and particulate removal ahead of spray guns in a finishing booth, where the 40 um element and automatic drain protect finish quality between scheduled maintenance.
Start with size and port: the 300 size with a 1/2 in PT port suits lines running larger pneumatic loads, while smaller 200/300 or larger 400/600 sizes step port and flow capacity up or down. Because flow is published as curves rather than a single rating, send us your air demand and we will confirm the right size against the datasheet before you order. On this unit the drain is automatic, which suits unattended or hard-to-reach installations; manual and differential-pressure drain versions are available if you prefer scheduled or load-linked draining. The 40 um element is the standard grade for general plant air, and the 5 um (W) element is the choice where finer particulate removal matters. The fitted round gauge reads in psi; square embedded gauges and MPa or bar scales are alternatives. PT thread is standard on this model, with G (BSPP) and NPT offered as order options, and the included bracket simplifies panel or frame mounting.
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. Send us your air demand and line conditions and we will confirm the sizing against the datasheet before you order.
The automatic drain discharges collected condensate on its own, which suits units mounted high, inside enclosures, or on lines that are not visited daily. Manual-drain and differential-pressure-drain versions of the same 300-size unit are available if you would rather drain on a schedule.
