AirTAC GFC300 · Two-Unit Set (filter regulator + lubricator)

Airtac B52-GFC Copper-Free Air Source Treatment Component B52-GFC300C10MC1W

The AirTAC B52-GFC Copper-Free Air Source Treatment Component B52-GFC300C10MC1W is a genuine G-series two-unit air-preparation set: a filter regulator that filters and regulates in one body, coupled to a lubricator. Two bodies do the work of three, with See datasheet ports, a 40 µm element, a differential-pressure drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the Airtac B52-GFC Copper-Free Air Source Treatment Component B52-GFC300C10MC1W

GFC is the AirTAC two-unit air preparation set: a filter regulator plus a separate lubricator, so one purchase covers filtration, pressure regulation and oil-mist lubrication of compressed air. This GFC300C10MC1W is a 300-size set with 3/8 in PT ports, a manual drain on the polycarbonate filter bowl, the 5 um fine filtration element in place of the standard 40 um grade, and an external round gauge reading in MPa. With manual drain, the regulator section adjusts from 0.05 to 0.9 MPa (7-130 psi); the set takes up to 1.0 MPa (145 psi) inlet between -5 and 70 C.

This is a genuine AirTAC part. The GFC two-unit range spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, PT (standard), G(BSPP) or NPT thread, 40 um standard or 5 um fine filtration, differential-pressure, automatic or manual drains, and square or round gauges in MPa, psi or bar scales. Rated flow is published as curves rather than a single figure, so we confirm the datasheet and sizing numbers 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). The set has no separate bracket code — the two 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.

Model Code: Airtac B52-GFC Copper-Free Air Source Treatment Component B52-GFC300C10MC1W

GFC300G-series two-unit set, 300 body — sets the port range.
C1Port size See datasheet. This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2".
(blank)Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)).
(blank)Standard type. Blank is standard, L is the low-pressure type.
(blank)Pressure gauge fitted (blank).
(blank)Gauge shape: Factory standard. C is round, F is square.
(blank)Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar.
(blank)Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist.
(blank)PT thread. PT is the default; G is BSPP and T is NPT.
(blank)No reverse-flow valve (the default).

Field order is size, port, drain, type, gauge, shape, scale, grade, thread, reflux — there is no bracket position on a combination set. Constituent units, orderable separately as spares: GFR300-C1 filter regulator and GL300-C1 lubricator.

Size Class & How It Differs From GC

  • GFC200PT1/8" - PT1/4"
  • GFC300PT1/4" - PT1/2"
  • GFC400PT3/8" - PT1/2"
  • GFC600PT3/4" - PT1"

A GFC is two units because filtering and regulating share one body. A GC is three separate units — filter, regulator and lubricator. Both filter, regulate and lubricate; the GFC is the shorter assembly, the GC keeps the filter and regulator serviceable as separate bodies.

Where the Airtac B52-GFC Copper-Free Air Source Treatment Component B52-GFC300C10MC1W Is Used

valve

Pneumatic clamping fixture

Feeds filtered, regulated and lubricated air to the clamp cylinders on a welding or assembly fixture, with the 5 um element protecting fine valve clearances downstream.

conveyor_belt

Packaging line diverters

Conditions the supply to the diverter cylinders and air-powered sealers along a packaging conveyor, with the manual drain bled at shift start and end.

factory

Workcell drop-leg supply

Mounted on a plant drop leg to prepare the air feeding small actuators and air tools across a production bay, with pressure set on the MPa gauge.

Is the Airtac B52-GFC Copper-Free Air Source Treatment Component B52-GFC300C10MC1W the Right Set?

Move up or down between sizes 200, 300, 400 and 600 to match the air demand of your line; this 300 set carries 3/8 in PT ports. Manual drain suits points where an operator can bleed the bowl on a schedule - choose automatic for unattended positions. The W code fits the 5 um element, worth it only where finer filtration matters, since it loads faster than the standard 40 um grade. Round gauges come in MPa (scale 1), psi (2) or bar (3); the C1 here reads MPa. PT is the standard thread; G and NPT are orderable options. Because rated flow is published as curves, not one number, ask us to confirm sizing against your application before ordering.

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
  • ✓ Two-unit (GFC) or three-unit (GC) layout
  • ✓ Oil mist acceptable downstream

Installation & Maintenance Notes

  • check Install with the airflow arrow: filter regulator 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 set 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, so if any branch must stay oil-free, take that branch off before the lubricator or use a GFR300-C1 filter regulator on its own.

Airtac B52-GFC Copper-Free Air Source Treatment Component B52-GFC300C10MC1W FAQ

AirTAC publishes G-series flow as performance curves rather than a single rated figure, so we do not quote one number here. Tell us your line conditions and we will confirm the flow and sizing figures from the datasheet on request.

The blank grade is 40 um, the standard general-purpose filtration. The W code fits a 5 um element for finer particle capture where valves or actuators need cleaner air. It filters more finely but loads faster, so it suits points where element condition is checked regularly.
