The AirTAC GFR Filter Regulator GFR400C15MJF1 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.
GFR400C15MJF1 is an AirTAC GFR400 filter regulator: filtration and pressure regulation combined in one body, with a drain bowl but no lubricator. This configuration comes with a manual drain, the standard 40 um filter element, an embedded square pressure gauge with MPa scale, and no mounting bracket. The port is PT1/2 (1/2 in PT thread, the standard for this code) and the bowl is polycarbonate (PC) at size 400. Regulator setting range with the manual drain is 0.05-0.9 MPa (7-130 psi); maximum working pressure is 1.0 MPa (145 psi) and operating temperature is -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 in to 1 in, G (BSPP) and NPT thread options, a choice of differential-pressure, automatic or manual drains, and 40 um or 5 um elements. Flow is published as curves rather than a single rating, so we confirm the datasheet and sizing 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.

Sits at the drop from a rotary-screw compressor ring main, knocking out bulk water and pipe scale and setting a stable working pressure for the downstream workshop.
Conditions the air feeding end-of-arm grippers and clamp cylinders in a weld cell, keeping actuator pressure repeatable from cycle to cycle.
Regulates the supply to rinsing nozzles and fill-valve actuators on a bottling line, where a steady setpoint keeps valve timing consistent.
Size 400 with a 1/2 in PT port serves medium-to-high plant air demand; step to the neighbouring size or port only after checking the published flow curve against your consumption. The manual drain (M) gives the wider 0.05-0.9 MPa (7-130 psi) setting range, while automatic or differential-drain versions set 0.15-0.9 MPa (20-130 psi). The standard 40 um element covers general plant air; order the W suffix for the 5 um grade where finer filtration is needed. Gauges are available as the embedded square type (as here) or an external round type, in MPa, psi or bar scales; G (BSPP) and NPT threads are catalogue options and a bracket can be ordered. Flow is published as curves, not a single rating, so ask us to confirm sizing 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.
There is no single rated figure to quote: AirTAC publishes G-series flow as curves only. Tell us your required flow and upstream pressure and we will confirm the sizing from the datasheet on request.
This code carries the embedded square gauge with an MPa scale (F1). If your team works in psi or bar, the gauge scale can be specified as 2 or 3 respectively at ordering, and an external round gauge is also available as an alternative to the square type.
