AirTAC GFR300-15 Filter Regulator (GFR30015AC4)
The AirTAC GFR300-15 Filter Regulator (GFR30015AC4) 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 PT1/2" ports, a automatic 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 GFR300-15 Filter Regulator (GFR30015AC4)
The GFR30015AC4 is an AirTAC G-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. The regulating range with the automatic drain fitted is 0.15-0.9 MPa (20-130 psi) and maximum inlet pressure is 1.0 MPa (145 psi). This build is size 300 with PT1/2 ports, the standard 40 um element, an automatic drain, and an external round pressure gauge; ask us to confirm the gauge scale fitted to this code on request.
It is a genuine AirTAC part from the G series, which spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in. Drain choices are differential-pressure (default), automatic and manual; element grades are 40 um standard and 5 um optional; gauge scales are published as MPa, psi and bar; and thread is PT as standard with G (BSPP) and NPT catalogue options. The size 300 bowl is polycarbonate (600 is aluminium alloy), operating temperature is -5 to 70 C non-freezing, and a bracket is included. Flow appears only as curves, 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.

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 GFR300-15 Filter Regulator (GFR30015AC4) Is Used
Automotive trim-line clamping fixtures
Placed at the drop feeding clamping and hold-down fixtures on an automotive trim line, holding fixture pressure constant through shift-long compressor cycling while the automatic drain keeps condensate out of the valves.
Palletizer cell gripper supply
Feeds the vacuum venturis and gripper cylinders of a palletizing cell, with the round gauge giving operators a visible pressure reference at the cell and the auto drain handling moisture from the header.
Maintenance-shop air drops
Installed on the drop lines of a plant maintenance shop so impact wrenches, ratchets and test rigs each draw filtered air at their own regulated pressure, independently of the shop header.
Is the AirTAC GFR300-15 Filter Regulator (GFR30015AC4) the Right Unit?
Choose this 300 size when your circuit wants a 1/2 in PT port; smaller 200 and larger 400/600 bodies step the port between 1/8 in and 1 in, and the published flow curves - not a single rating - decide which step your air demand needs, so ask us to confirm sizing on request. The 40 um element here is the standard grade for general cylinder and valve protection; the W option gives 5 um. The automatic drain suits unattended lines, gauge scales run MPa, psi or bar (confirm the exact scale on this code with us), and G or NPT thread can be ordered instead of PT.
Quick checklist
- ✓ Body size for your peak flow (PT1/2" 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 GFR300-15 Filter Regulator (GFR30015AC4) FAQ
AirTAC publishes G-series flow as curves rather than a single rated figure, so no rated number is quoted here. Send us your working pressure and air consumption and we will confirm the flow and sizing from the datasheet on request before you order.
The C is the external round pressure gauge option on this family. The catalogue scale digits are 1 for MPa, 2 for psi and 3 for bar, and the digit on this code sits outside the decoded set, so rather than guess we confirm the exact gauge and scale fitted on request before you order.
