The AirTAC GFR300C15C2 AirTAC Filter Regulator PT1/2, 40 um 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 See datasheet ports, a differential-pressure 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 GFR300C15C2 is an AirTAC GFR300 filter regulator that combines two jobs in one body: it removes water and particulate from compressed air through a 40 um element, then regulates downstream pressure across a 0.15-0.9 MPa (20-130 psi) setting range. This configuration is sized with a PT1/2 port, uses the differential-pressure drain (default) to bleed condensate automatically as flow passes through, carries a fitted round gauge scaled in psi, and includes a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the GFR300 series, one of four sizes (200/300/400/600) in the GFR filter-regulator family. Related configurations offer a 5 um element (code W), automatic or manual drain, G (BSPP) or NPT threads, and alternate gauge scales in MPa or bar. Flow figures for this series are published as curves rather than a single rating, so contact 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. 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.

Conditioning and regulating the supply to the air cylinder that drives a stamping or forming head, keeping water and swarf out of the valve stack while holding a steady set pressure stroke to stroke.
Supplying clean, regulated air to the sealing and clamping cylinders on a carton or bag packaging conveyor, where fluctuating line pressure would cause inconsistent seals.
Filtering and regulating shop air at the bench drop feeding lab apparatus and pneumatic test fixtures, with the 40 um element catching pipe scale and the drain removing accumulated condensate.
Choose the size and port step against the air demand of the circuit: the GFR300 with its PT1/2 port sits in the middle of the GFR range (200/300/400/600), where larger sizes carry larger ports and more flow. Pick the drain to match maintenance access: differential-pressure (this unit, default), automatic (code A) for unattended drains, or manual (code M) where you want operator-controlled bleeding. The 40 um element is standard; specify the 5 um W grade where finer particulate protection is needed. Gauge scale is selectable (MPa, psi or bar) and this unit ships with a round psi gauge fitted; PT thread is standard with G (BSPP) and NPT available to order, and a bracket is included. Flow for this series is published as curves, not a single rating, so 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. 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 rather than a single rated figure, so no single number can be quoted honestly. Send us your application details and we will confirm the datasheet flow figures against your required PT1/2 port size on request.
The differential-pressure drain is the default: it bleeds condensate from the bowl automatically as air flows through, with no operator action. If your duty cycle leaves long idle periods, the automatic drain (code A) or manual drain (code M) versions of the same GFR300 filter regulator can be specified instead.
