AirTAC GC400-15 FRL Unit (GC40015LNK)
The AirTAC AirTAC GC400-15 FRL Unit (GC40015LNK) is a genuine G-series three-unit F.R.L. combination: a separate filter, a separate regulator and a separate lubricator assembled as one air-preparation station. It has PT1/2" ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GC400-15 FRL Unit (GC40015LNK)
The GC40015LNK is a three-piece AirTAC G-series F.R.L. combination - separate air filter, pressure regulator and lubricator - supplied in size 400 with PT1/2 ports and a PT thread. The K in the code means a reverse (check) valve is fitted in the regulator section, so downstream pressure is held if the upstream supply dips. This version is the low-pressure type with no gauge, a standard 40 um filter element, and a differential-pressure drain on the polycarbonate (PC) filter bowl.
This is a genuine AirTAC part. The G-series spans sizes 200 to 600 with options including automatic or manual drains, a 5 um element, embedded square or external round gauges, and G (BSPP) or NPT threads as catalogue choices. Maximum working pressure is 1.0 MPa (145 psi); operating temperature is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so we confirm figures from the datasheet 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. The combination has no separate bracket code — the three units couple together with their own mounting hardware. 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, gauge, shape, scale, grade, thread, reflux — there is no bracket position on a combination. Constituent units, orderable separately as spares: GF400-15 filter, GR400-15 regulator and GL400-15 lubricator.
Size Class & How It Differs From GFC
- GC200PT1/8" - PT1/4"
- GC300PT1/4" - PT1/2"
- GC400PT3/8" - PT1/2"
- GC600PT3/4" - PT1"
A GC is three separate units, so the filter and the regulator can each be serviced or replaced on their own. A GFC is the two-unit set, where filtering and regulating share one body — shorter, but the two functions come as one part. Both filter, regulate and lubricate.

Where the AirTAC GC400-15 FRL Unit (GC40015LNK) Is Used
Pneumatic clamping fixture
Supplies filtered, low-pressure regulated air to clamping cylinders on a machining cell, where the fitted check valve helps hold the clamp circuit while the upstream supply fluctuates.
Pick-and-place module
Conditions the air feeding a pick-and-place handling module on an assembly line, keeping particles and water out of the valve island while the lubricator mists the actuators' air.
Test-rig actuation skid
Provides clean, regulated, lubricated air to the actuated cylinders on a low-pressure test rig, with the check valve holding the set circuit pressure during supply interruptions.
Is the AirTAC GC400-15 FRL Unit (GC40015LNK) the Right Station?
Pick this model over the plain GC40015LN when a supply-side pressure dip must not dump your regulated downstream pressure - the fitted check valve holds the circuit while the upstream side recovers, useful on clamping and holding circuits. Size 400 with PT1/2 ports suits a 1/2 inch main feeding multiple actuators. The L marks the low-pressure regulator type; give us your set pressure and we will confirm the adjusting range on the datasheet. Drain is the differential-pressure default (automatic A and manual M exist). Filter grade is 40 um standard, 5 um with W. Thread is PT as standard; G (BSPP) and NPT (T) are orderable options, and a square or round gauge can be added.
Flow for G-series units is published as curves, not a single rated figure, so send your flow demand and we will confirm sizing against the AirTAC datasheet before you order.
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
- ✓ Three-unit (GC) or two-unit (GFC) layout
- ✓ Oil mist acceptable downstream
Installation & Maintenance Notes
- check Install with the airflow arrow: filter first, lubricator last.
- check Mount vertically, bowls down.
- 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 the oil level.
- check Keep the station above freezing (-5 to +70 °C, unfreeze).
The PC bowls must not be cleaned with solvents — wipe them with a dry cloth. The lubricator adds an oil mist downstream of the regulator. If any branch of the line must stay oil-free, take that branch off before the lubricator, or use a GR400-15 regulator with a GF400-15 filter on that branch.
AirTAC GC400-15 FRL Unit (GC40015LNK) FAQ
We do not state a rated flow number because AirTAC publishes G-series flow as curves rather than a single rating. Share your application's flow and pressure and we will confirm the sizing from the datasheet on request before you order.
K means a reverse (check) valve is fitted in the regulator section. It blocks reverse flow, so the regulated downstream pressure is held if the upstream supply drops - the plain GC40015LN without K has no check valve. We can confirm details on the datasheet on request.
