Airtac GFR Filter Regulator GFR400C15F1
The AirTAC GFR Filter Regulator GFR400C15F1 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 GFR400C15F1
GFR400C15F1 is an AirTAC G-series filter regulator - filtration and pressure regulation combined in a single body. It strips water and particulate from the compressed air line and holds the downstream pressure at the setting you dial in. This configuration is the 400 frame with a PT1/2 port, the standard 40 um filter element, the differential-pressure drain (the default drain, which passes condensate as the pressure differential across it rises) and an embedded square pressure gauge scaled in MPa.
This is a genuine AirTAC part. Maximum working pressure is 1.0 MPa (145 psi), the standard regulating range with the differential-pressure drain is 0.15-0.9 MPa (20-130 psi), and the working temperature range is -5 to 70 C (non-freezing). The 400-size bowl is polycarbonate; the same GFR family spans 200, 300, 400 and 600 frames with automatic or manual drains, a 5 um (W) element, G (BSPP) or NPT threads, psi or bar gauge scales and a reverse-valve (K) option. G-series flow is published as curves rather than one rated number, so we confirm datasheet and sizing 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.

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 GFR400C15F1 Is Used
Pneumatic press feed
Point-of-use supply for a 1/2 inch pneumatic press or riveting station: water and pipe scale are stripped from the plant air line and the press cylinder works at a fixed, repeatable setting.
Packaging machine air
Conditioning the main air drop on a cartoning or wrapping line, where the embedded MPa gauge lets operators check the machine supply pressure at a glance.
Conveyor gate actuators
Regulated air for diverter gates and stop cylinders along a conveyor system, with the differential-pressure drain passing collected condensate while the line keeps running.
Is the Airtac GFR Filter Regulator GFR400C15F1 the Right Unit?
The 400 frame with its 1/2 inch port is the natural step for 1/2 inch machine drops; step down to GFR300 for 1/4-3/8 inch circuits or up to GFR600 where 3/4-1 inch lines demand more flow. The remaining choices on this family are all decodable from the code: drain type (differential-pressure standard, A automatic, M manual), element grade (40 um standard, W for 5 um), gauge scale (1 MPa, 2 psi, 3 bar), reverse valve (K), thread (PT standard, G or NPT to order) and the J no-bracket version. Because AirTAC publishes flow as pressure-drop curves, not a single rating, send us your line pressure and air demand and we will confirm sizing against the datasheet 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 GFR400C15F1 FAQ
AirTAC publishes G-series capacity as pressure-drop curves rather than a single rated flow figure, so quoting one number would be guesswork. Send us your working pressure and air demand and we will confirm the flow figures from the datasheet on request.
GFR identifies the filter-regulator family, 400 is the frame size, 15 is the 1/2 inch port code, and F1 is the embedded square gauge with an MPa scale. The absence of a drain letter gives the differential-pressure drain, and the absence of W gives the standard 40 um element. PT is the standard thread; G (BSPP) and NPT are catalogue options to order.
