The AirTAC GFR300C15MF2G AirTAC Filter Regulator G1/2 40um Manual 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 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 AirTAC GFR300C15MF2G is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your set point, all in a single body. This unit is built on the 300 size with a G1/2 port, 40 um standard filtration, a manual drain on the polycarbonate bowl, and a square pressure gauge reading in psi. The regulator is the standard type with a 0.05-0.9 MPa (7-130 psi) adjustment range, the unit accepts up to 1.0 MPa (145 psi) inlet pressure, and it operates from -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options include 5 um filtration (code W), automatic or manual draining, G or NPT threads, and gauge scales in MPa, psi or bar. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Filter and regulate the air feeding gripper and pusher cylinders on a bottling line, with the manual drain bled at shift start to clear condensate that collected overnight.
Point-of-use conditioning ahead of a CNC machine's pneumatic clamp circuit, holding a steady pressure setting while the 40 um element stops scale and pipe rust reaching the valve.
Supply the air cylinders that divert cartons on a distribution conveyor, with the psi gauge letting operators check and reset line pressure after each changeover.
Choose the size by the air demand of your line: the 200, 300, 400 and 600 frames step up in port size and capacity, and this 300 unit carries a G1/2 port. Drain type is a real decision: the manual drain fitted here needs an operator to bleed the bowl, while automatic and differential-pressure drains discharge condensate without attention - note that the manual-drain version also carries the wider 0.05-0.9 MPa (7-130 psi) regulation range. Filtration is 40 um as standard; specify the W option for 5 um where downstream equipment needs finer air. The square gauge on this unit reads psi, with MPa and bar scales available as alternatives. The thread here is G (BSPP) - PT is the standard thread and G or NPT are order options - and a mounting bracket is included. Because flow is published as curves rather than a single rating, send us your air demand 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 figure, so we do not quote a number here. Send us your air demand and operating pressure and we will confirm the flow and the full datasheet for this unit on request.
This configuration uses a manual drain: an operator opens it to bleed collected condensate from the bowl. It also carries the wider 0.05-0.9 MPa (7-130 psi) regulator adjustment range. If the unit will sit where nobody drains it regularly, ask us about the automatic-drain version of the same GFR300 filter regulator.
