Airtac GFR Filter Regulator GFR400C15AJF1W
The AirTAC GFR Filter Regulator GFR400C15AJF1W 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 GFR400C15AJF1W
The AirTAC GFR series filters and regulates compressed air in one body: a drain bowl with a replaceable element removes water and particulate, then an integrated regulator sets the downstream working pressure. The GFR400C15AJF1W is the size 400 frame with a 1/2 in PT (standard) port, automatic drain, the optional 5 um element for finer filtration than the standard 40 um grade, and an embedded square pressure gauge reading in MPa. Maximum inlet pressure is 1.0 MPa (145 psi); with the automatic drain the regulation range is 0.15-0.9 MPa (20-130 psi), and the PC (polycarbonate) bowl works from -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The G series covers sizes 200, 300, 400 and 600 (larger sizes give larger ports and more flow), with drain, element-grade, gauge, thread and bracket options across the range; G (BSPP) and NPT threads are catalogue choices besides the standard PT. Flow performance is published as curves rather than a single rated figure, so ask us to confirm datasheet and sizing details for your application on request. Medium is compressed air only.

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)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |

| (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. |

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 GFR400C15AJF1W Is Used
Spray-paint booth supply
Point-of-use conditioning ahead of air-assisted spray guns on a finishing line, where the 5 um element catches finer particulate than the standard grade before finishing work.
Test-bench instrumentation air
Regulated, filtered air for pneumatic instrumentation and gauging on a laboratory or QC test bench, with the 5 um element helping protect sensitive devices.
Woodwork shop nailers and sanders
A point-of-use station for nail guns, orbital sanders and blow guns in a joinery shop, combining water removal, pressure setting and finer 5 um filtration.
Is the Airtac GFR Filter Regulator GFR400C15AJF1W the Right Unit?
Size 400 with a 1/2 in PT port sits at the upper-middle of the G range (200/300/400/600); move between frames or port codes if your branch line demands it. The key choice here is filtration grade: 40 um is the standard element, while the W in this code specifies the finer 5 um element - pick it where spray guns, instrumentation or other sensitive devices sit downstream. Drains are offered as differential-pressure (default), automatic (this code) and manual; the automatic drain gives the 0.15-0.9 MPa (20-130 psi) regulation span. Gauge scale, G or NPT thread and a mounting bracket are orderable options; this code omits the bracket. Flow is published as curves, not a single rating, 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 GFR400C15AJF1W FAQ
There is no single rated flow figure to quote: AirTAC publishes G-series performance as curves. Send us your working pressure and air consumption and we will confirm the correct sizing from the datasheet on request.
40 um is the standard grade and suits general plant-air duty. The W suffix (this model) specifies the optional 5 um element for finer protection of spray guns, instrumentation and other sensitive devices, chosen per point of use.
