Airtac GFR Filter Regulator GFR400C10C1
The AirTAC GFR Filter Regulator GFR400C10C1 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 GFR400C10C1
The AirTAC GFR series combines a water-and-particulate filter and a pressure regulator in one body, so a single component conditions the air and sets the working pressure downstream. This GFR400C10C1 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 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, a 5 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.

Where the Airtac GFR Filter Regulator GFR400C10C1 Is Used
Packaging machine valve-island supply
Feeding a pneumatic valve manifold on a carton-forming packaging line: the GFR400C10C1 drops the main supply to the working pressure the manifold needs while keeping line moisture and scale out of the valves.
Conveyor blow-off nozzle bank
Supplying the air-blow-off nozzles that clear dust and residue from bottles or parts travelling along a bottling or processing conveyor, with the regulator set to the pressure the nozzle bank was designed for.
Laboratory bench air header
Conditioning the compressed-air drop that feeds bench-top instruments and pneumatic sample-handling fixtures in a lab, where one 3/8 inch regulated branch serves several small outlets.
Is the Airtac GFR Filter Regulator GFR400C10C1 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 here suits continuously flowing lines; choose the A-coded automatic drain for intermittent duty or the M-coded manual drain if operators can bleed the bowl on a schedule, which also widens the regulating range to 0.05-0.9 MPa (7-130 psi). The 40 um element is the standard grade; specify W for 5 um where finer protection is needed. PT is the standard thread with G (BSPP) and NPT available as catalogue options, a bracket is included, and the MPa round gauge fitted here can be ordered as an embedded square gauge instead. Because AirTAC publishes flow as curves, not a single rated figure, 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 GFR400C10C1 FAQ
AirTAC publishes flow for the GFR series as characteristic curves, not as a single rated figure, so quoting one number would not be honest. Tell us your supply pressure, set pressure and air consumption and we will confirm sizing against the curves and send the datasheet on request.
The differential-pressure drain on this model bleeds condensate whenever airflow passes the unit, which suits continuously running lines. Choose the A-coded automatic drain for intermittent or low-flow duty, or the M-coded manual drain when an operator can bleed the bowl on a schedule - the manual-drain version also regulates from 0.05 MPa instead of 0.15 MPa.
