Airtac GFR Filter Regulator GFR400C10C1K
The AirTAC GFR Filter Regulator GFR400C10C1K 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.

About the Airtac GFR Filter Regulator GFR400C10C1K
The AirTAC GFR series combines a water-and-particulate filter and a pressure regulator in one body. This GFR400C10C1K is a 400-size unit with a PT3/8 port, a differential-pressure drain that bleeds condensate as airflow passes through, a 40 um standard filter element, a round pressure gauge reading in MPa and a fitted reverse (check) valve that helps hold downstream pressure if the upstream supply dips. 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, a 5 um element, an embedded square gauge, or without the 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.

|---|---|
| C1 | Port size See datasheet. This body offers 10 = PT3/8", 15 = PT1/2". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |

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.

Where the Airtac GFR Filter Regulator GFR400C10C1K Is Used
Pneumatic clamp circuit on a welding fixture
Supplying clamping cylinders on a welding or assembly fixture, where the regulator holds the clamp pressure and the fitted check valve helps keep the circuit from relaxing if the plant supply drops momentarily.
Machine-tool pneumatic workholding
Conditioning the supply to a chuck, vise or collet-actuation circuit on a CNC machine tool, keeping moisture and swarf-carrying air out of the actuator while holding a stable set pressure.
Diaphragm valve actuation on a process skid
Regulating the air that strokes pneumatically actuated process valves on a water-treatment or chemical dosing skid, with one 3/8 inch conditioned branch per valve group.
Is the Airtac GFR Filter Regulator GFR400C10C1K the Right Unit?
The 400 size with its 3/8 inch port sits in the middle of the G range; step down to 300 or up to 600 when your line volume calls for a different port, and match the step against the flow curves before ordering. 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. The K suffix here means a reverse (check) valve is already fitted; order the non-K code if you do not want it. The 40 um element is standard, with 5 um available under W. 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
- ✓ Body size for your peak flow (See datasheet here)
- ✓ Element 40 µm or 5 µm
- ✓ Drain sets the regulating band
- ✓ Gauge fitted, shape and scale
- ✓ Thread PT, G (BSPP) or NPT
- ✓ Oil needed downstream? Use GFC instead
Installation & Maintenance Notes
- check Mount vertically, bowl down, following the airflow arrow.
- check One body does the filtering and the regulating — no separate regulator needed.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Adjust only within 0.15 - 0.9 MPa (20 - 130 psi).
- check Drain condensate before the bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
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 GFR Filter Regulator GFR400C10C1K FAQ
AirTAC publishes flow for the GFR series as characteristic curves rather than a single rated number, so we do not quote one figure as a rating. Send us your supply pressure, set pressure and air consumption and we will confirm sizing against the curves and provide the datasheet on request.
K means a reverse (check) valve is fitted in this unit: air passes normally from inlet to outlet, but reverse flow from the downstream side is blocked. That helps hold pressure on the equipment side during upstream dips; if you do not want the check function, order the non-K code GFR400C10C1.
