The AirTAC GFR Filter Regulator GFR400C10C1W 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 combines a water-and-particulate filter and a pressure regulator in one body. This GFR400C10C1W is a 400-size unit with a PT3/8 port, a differential-pressure drain that bleeds condensate as airflow passes through, a 5 um fine filter element (the W option, instead of the 40 um standard) and a round pressure gauge reading in MPa. It is a filter regulator only - there is no lubricator in this body. It runs on compressed air at up to 1.0 MPa (145 psi) inlet, adjusts outlet pressure from 0.15 to 0.9 MPa (20-130 psi), and works from -5 to 70 C (non-freezing). The 400 size uses a polycarbonate bowl.
This is a genuine AirTAC part. The G series is offered in 200, 300, 400 and 600 sizes with ports from 1/8 to 1 inch, and this configuration can be ordered instead with a G (BSPP) or NPT thread, an automatic or manual drain, the standard 40 um element, an embedded square gauge, or a fitted check valve. AirTAC publishes flow as characteristic curves rather than a single rating, so ask us to confirm sizing and request the datasheet for your application.

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.

Feeding the air-driven sample pumps and actuated switching valves inside an analyser shelter, where the 5 um element keeps fine particulate out of close-tolerance pneumatic components.
Conditioning the branch that feeds pneumatic agitators and air-controlled spray equipment at a paint finishing station, where the regulator sets gun-side pressure and the fine element guards the air side of the equipment.
Supplying compact pneumatic presses, markers and crimping heads on a production bench, with one regulated 3/8 inch drop serving the tool group at the pressure the tooling was set up for.
Choose the 5 um W element over the 40 um standard when the downstream equipment tolerates less particulate carryover; if only bulk dirt and water removal is needed, the non-W code with the 40 um element is the standard choice. The 400 size with its 3/8 inch port sits in the middle of the G range - step to 300 or 600 as your port and volume requirements dictate, and verify the step against the flow curves. The differential-pressure drain suits continuously flowing lines; the A-coded automatic drain covers intermittent duty and the M-coded manual drain allows hand bleeding plus a wider 0.05-0.9 MPa (7-130 psi) regulating range. PT is the standard thread with G (BSPP) and NPT as catalogue options, a bracket is included, and the MPa round gauge can be ordered as an embedded square gauge instead. AirTAC publishes flow as curves, not a single rated figure, 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 GFR series as characteristic curves, not as a single rated figure, so no single number is quoted here. Share your supply pressure, set pressure and consumption and we will confirm sizing against the curves and send the datasheet on request.
The W suffix on this model means the 5 um element is fitted, which suits circuits with close-tolerance pneumatics or sensitive downstream equipment. The 40 um element on the non-W code is the standard grade for general dirt and water removal; if in doubt, tell us what the unit feeds and we will confirm the right grade.
