The AirTAC AirTAC GFR300C08F1TK Filter Regulator, NPT1/4 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.
The GFR300C08F1TK is an AirTAC GFR300 filter regulator: one body that removes water and particulate from compressed air and holds the downstream pressure at your setpoint. This configuration has a 1/4 in NPT port, the standard 40 um filter element, a differential-pressure drain, an embedded square pressure gauge scaled in MPa, a fitted reverse (check) valve, and a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the regulation range is 0.15-0.9 MPa (20-130 psi), and the operating temperature is -5 to 70 C (non-freezing). The bowl on this 300 size is polycarbonate.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, PT as the standard thread and G or NPT available to order, plus drain, filter-grade, gauge-scale and check-valve options. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet and sizing figures for your application 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.

Feed a pick-and-place robot's gripper cylinders from one filtered, regulated drop: water and swarf are stripped out before they reach the valve stack, and the setpoint holds actuation consistent cycle after cycle, with the fitted check valve blocking reverse flow at the unit.
Supply the pneumatic gates, pushers and stoppers along a packaging or distribution conveyor from a single GFR300 drop, so the cylinders see clean air at one steady pressure regardless of swings in the shop supply.
Point-of-use preparation for a packaging machine's cylinder and jet-air circuits: the 40 um element protects the machine's valves from particulate and condensed water while the regulator holds the pressure the machine was set up for.
Every choice in this code is decodable: size (200/300/400/600) sets the port and where your demand sits on the flow curve, so step up a size if your consumption is near the top of a smaller unit; drain type (differential-pressure standard, automatic with A, manual with M); filter grade (40 um standard, 5 um with W); gauge scale (MPa, psi or bar) and square vs optional external round gauge; thread (PT standard, G or NPT to order); and the K check-valve option. This unit is the 300 size with a 1/4 in NPT port, differential-pressure drain, 40 um element, MPa square gauge and check valve fitted. Because AirTAC publishes flow as curves rather than a single rated figure, send us your flow and pressure requirements and we will confirm sizing against the datasheet before you order.
Quick checklist
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 publishes flow for the GFR300 series as curves, not as a single rated number, so we do not quote a figure here. Send us your required flow and working pressure and we will confirm the sizing from the datasheet on request.
This unit carries the standard differential-pressure drain, which passes collected condensate when the pressure differential across the filter element rises. If you prefer, order the A code for an automatic drain or M for manual draining; note that the manual-drain version also widens the regulation range down to 0.05 MPa (7 psi).
