The AirTAC GFR200C08F2GK AirTAC Filter Regulator G1/4, 40 um 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 AirTAC GFR200C08F2GK is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This size 200 unit has a G1/4 (BSPP) port, the standard 40 um filter element, and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element is high enough - no daily manual draining. The fitted square gauge reads in psi, a reverse/check valve holds downstream pressure when the supply is lost, and a mounting bracket is included. The polycarbonate bowl is transparent for a quick fluid-level check, and the maximum inlet pressure is 1.0 MPa (145 psi) with an operating temperature of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR filter-regulator line spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, optional 5 um filtration (code W), automatic or manual drains, alternative gauge scales, and NPT or G thread variants. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figure for your application before ordering.

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.

Clean, regulated air feeding tool-change cylinders and clamping fixtures on a machining centre, with the check valve holding clamp pressure if the shop supply drops.
Conditioned air for sealing jaws and divertor cylinders on a carton packaging line, where the 40 um element protects directional valves from water and debris.
Filtered, pressure-set air to benchtop test rigs and pneumatic sample-handling devices, with the psi gauge giving operators a direct reading at the setpoint.
Start with the port and size: this unit is size 200 with a G1/4 port; step up to GFR300/400/600 if your line needs more flow or a larger connection. Choose the drain to match maintenance habits - differential-pressure (this unit) drains itself under load, automatic (code A) drains on a cycle, manual (code M) needs someone to open it. The standard element is 40 um; specify 5 um (W) only where downstream equipment needs finer filtration. The fitted square gauge here reads psi; MPa and bar scales and an external round gauge are alternatives. Thread is G (BSPP) on this code - PT is the standard thread and NPT is an order option, stated as specification, not delivery. A bracket is included; on GF/GR/GL/GFR units, code J omits it.
One honest note on sizing: AirTAC publishes flow for this family as curves, not a single rated number, so we do not quote a flow figure here. Send us your application details and we will confirm the 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 GFR series as performance curves rather than a single rated figure, so we do not state a flow number here. Send us your application - port size, downstream demand and line pressure - and we will confirm the relevant datasheet figure for you before you order.
The K code means a reverse/check valve is fitted: if the upstream supply fails, the valve holds the regulated downstream pressure instead of venting it - useful for clamps or cylinders that must stay put. The drain is differential-pressure type, meaning condensate collected in the polycarbonate bowl is discharged automatically when the pressure differential across the filter element rises; no manual draining is required. If you prefer a timed automatic drain or a simple manual drain, those are available as order options.
