Airtac GFR Filter Regulator GFR400C10AF1K
The AirTAC GFR Filter Regulator GFR400C10AF1K 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 GFR400C10AF1K
GFR400C10AF1K is an AirTAC G-series filter regulator: filtration and pressure regulation combined in one body, with a drain bowl but no lubricator. This code decodes as the 400 size with a 3/8 in PT port, automatic drain, the standard 40 um filter element, the embedded square pressure gauge graduated in MPa and, per the K suffix, a reverse (check) valve fitted; the mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi), operating range is -5 to 70 C (non-freezing), the 400-size bowl is polycarbonate, and with automatic drain the regulator adjusts from 0.15 to 0.9 MPa (20-130 psi).
This is a genuine AirTAC part. The G-series filter regulator runs from size 200 to 600 with ports from 1/8 in to 1 in, with manual or differential-pressure drains, a 5 um element (W), G or NPT threads, psi or bar gauge scales and versions without the check valve available under their own codes. Flow is published as curves rather than a single rating, so we confirm datasheet figures 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.

| GFR400 | G-series filter regulator, 400 body — sets the port range. |
|---|---|
| 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)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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 GFR400C10AF1K Is Used
Pneumatic punching press
Filters and regulates the air to the clutch and hold-down cylinders of a pneumatic press, with the K-suffix check valve in the code blocking reverse flow from the downstream circuit.
Rotary indexing assembly table
Supplies the indexing drive and clamp circuits of a rotary indexing table with clean, regulated air, with the automatic drain clearing condensate on continuous production duty.
Bottling line conveyor gates
Feeds the gate and stopper cylinders along a bottling line conveyor, holding a steady setting on the MPa gauge as containers pass the station.
Is the Airtac GFR Filter Regulator GFR400C10AF1K the Right Unit?
This is the 400 frame with a 3/8 in PT port, automatic drain, 40 um element, MPa square gauge and the K-suffix check valve; the same unit without the check valve carries the GFR400C10AF1 code. Alternatives to decode when comparing: manual (M) or differential-pressure (blank) drains, the 5 um element (W), psi or bar gauge scales, and G or NPT threads instead of the PT standard. Adjust range is 0.15-0.9 MPa (20-130 psi) with automatic drain, and the mounting bracket is included.
AirTAC publishes flow for this family as curves, not a single rated figure, so ask us to confirm the datasheet and check the sizing against your application before you order.
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 GFR400C10AF1K FAQ
AirTAC publishes flow for this family as curves, not as a single rated figure, so no flow number is quoted here. Send us your required flow and working pressure and we will confirm the datasheet curve for this 400 size, 3/8 in port unit on request.
This code carries the embedded square pressure gauge graduated in MPa. AirTAC also lists psi and bar scale gauges and a no-gauge version under their own order codes; tell us which scale your panel reads and we will confirm the matching code.
