The AirTAC Airtac GFR Filter Regulator GFR300C15AC1 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.
GFR300C15AC1 is a genuine AirTAC GFR series filter regulator, combining filtration and pressure regulation in one body with a drain bowl and no lubricator. This code is size 300 with PT1/2 in ports, the standard 40 um element, an automatic drain, and the external round pressure gauge in MPa scale. With the automatic drain, the regulated outlet is adjustable over 0.15-0.9 MPa (20-130 psi), and condensate is discharged without operator attention.
Maximum inlet pressure is 1.0 MPa (145 psi) and working temperature is -5 to 70 C, non-freezing; the size 300 bowl is polycarbonate (PC), while 600-size bowls are aluminium alloy. The GFR family also runs in 200/400 sizes with ports from 1/8 in to 1 in, G (BSPP) or NPT threads, a 5 um W element option, square embedded gauges, a reverse (check) valve option and bracket choices. Flow is published as curves rather than a single rating, so we confirm flow and 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.

Condition and regulate air to the cylinder-actuated gates and stoppers along a bottling conveyor, with the automatic drain coping with condensate through long shifts.
Filtered, regulated air to the valve islands driving taping heads and clamps on a case sealer, fed through the 1/2 in ports.
Point-of-use regulation for pick-and-place robot grippers and end-of-arm tooling, with the MPa round gauge letting technicians set and read pressure at the cell.
Choices that matter when ordering a GFR300: size and port (200 to 400 bodies, ports 06 = 1/8 in through 25 = 1 in) - this code is 300 with 1/2 in PT ports; drain type, where A (this code) drains automatically, the default is differential-pressure and M is manual (manual widens regulation to 0.05-0.9 MPa / 7-130 psi); element grade, 40 um standard or 5 um W; and gauge - this code carries the external round gauge in MPa, while embedded square gauges in MPa/psi/bar scales are other options. Thread is PT as standard, with G (BSPP) and NPT as catalogue options. Flow appears only as curves, not a single rating, so send your demand and we will confirm the right size on request.
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 G series as curves, not as a single rated figure, so we do not quote one number here. Give us your line pressure and consumption and we will confirm the correct size from the GFR300 datasheet on request.
The A in GFR300C15AC1 specifies the automatic drain, which discharges condensate without anyone opening it; the default differential-pressure drain operates on a pressure differential, and M specifies manual. Drain type also sets the regulation window: automatic and differential-pressure units adjust 0.15-0.9 MPa (20-130 psi), while manual-drain versions adjust 0.05-0.9 MPa (7-130 psi).
