The AirTAC GFR Filter Regulator GFR400C15MJC1 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 GFR series filters water and particulate from compressed air and regulates pressure in a single body. The GFR400C15MJC1 is the 400 size with a PT1/2 port, a manual drain bowl, the standard 40 um element, an external round pressure gauge on an MPa scale, and no mounting bracket (the J code), suiting installations where the body is fixed by its own port connections or a customer plate. Maximum inlet pressure is 1.0 MPa (145 psi), the manual-drain regulation range is 0.05-0.9 MPa (7-130 psi), and the polycarbonate bowl is rated for -5 to 70 C, non-freezing.
This is a genuine AirTAC part. Across the G series you can move between sizes 200 to 600, ports from 1/8 to 1 inch, automatic or differential-pressure drains, a 5 um element, embedded square or external round gauges in MPa, psi or bar scales, G (BSPP) or NPT threads, and bracket options. Flow appears in the catalogue as curves, not a single rating, so we confirm the figures you need from the datasheet 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.

Regulate atomizing air to spray guns at a paint booth wall, where the 40 um element catches pipe scale and water carryover and the external round gauge gives the painter a clear set-point reading.
Drop into the prep panel ahead of a machine's directional-valve manifold, regulating one stable supply pressure for the whole station while the manual drain is bled during scheduled maintenance.
Set and hold the working pressure for a light pneumatic bench press, with the round MPa gauge letting operators re-verify the setting at every product changeover.
Take the 400 size for 1/2 inch porting or when the smaller 300 body would sit at the top of its flow curve - ask us to check the curve against your duty before ordering. The manual drain keeps the lowest regulation floor (0.05-0.9 MPa / 7-130 psi) and suits units an operator can reach; automatic or differential drains suit enclosed or unattended panels. The standard 40 um element is right for general machine air prep; step to the W-coded 5 um element for fine pilot valves. The C code here orders an external round gauge on an MPa scale instead of the embedded square default, with psi and bar scales also available. Thread is PT as standard; G (BSPP) and NPT are catalogue options, and the J code deletes the bracket.
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.
Flow for this series is published as curves rather than a single rated number, so there is no one figure to quote. Share your operating pressure and demand and we will confirm the sizing from the datasheet on request.
It orders an external round pressure gauge on an MPa scale instead of the default embedded square gauge. Both indicate the regulated downstream pressure; the round gauge is often chosen for panel doors and enclosures where it is read at a glance. Psi and bar scales are also available to order.
