The AirTAC GR30010LF2T AirTAC Air Pressure Regulator, NPT3/8 is a genuine G-series air pressure regulator. It holds a stable downstream pressure over the range 0.05 - 0.4 MPa (7 - 58 psi) with PT3/8" ports, and ships with a pressure gauge. A regulator does not filter the air — put a GF filter upstream, or use a GFR filter regulator, when water and particulate must also be removed.
The GR30010LF2T is an AirTAC GR-series air pressure regulator: it does one job, holding a stable downstream pressure from a compressed-air supply. This is the low-pressure (L) type, so the setting range tops out at 0.4 MPa, and it carries a 3/8 in NPT port in the 300 size. The square gauge fitted to this unit reads in psi, so the operator can set and monitor line pressure directly without converting scales. Because it is a regulator only, there is no filter bowl and no lubricator in this unit - pair it upstream or downstream with separate filter and lubricator stages if the line needs them.
This is a genuine AirTAC part. The GR family spans the 200, 300, 400 and 600 sizes with port sizes from 1/8 to 1 inch, and options include standard or low-pressure regulation, embedded square or external round gauges in MPa, psi or bar scales, a reverse/check valve, bracket or panel mounting, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing against your application before ordering.

Specifications follow the official AirTAC G-series air-preparation data. Note the GR temperature range is -20 to +70 °C, wider than the other G-series units. A regulator has no bowl and no filter element, so there is no filtering grade. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

|---|---|
| 10 | Port size PT3/8". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| L | Low-pressure type — 0.05 - 0.4 MPa (7 - 58 psi). Blank is standard, L is the low-pressure type. |
| (blank) | Fixing bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
Field order is size, port, type, bracket, gauge, gauge shape, scale, thread, reflux — a blank position takes the default. Example: GR300-08LNK is a 300 body, PT1/4", low-pressure type, no gauge, with 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 rather than from a single rated figure.

| Line order | Filter first, then regulator, then lubricator |
Set a gentle, stable feed pressure to spray guns and low-pressure atomizing lines where a standard regulator range would run too high for the coating equipment.
Trim and hold the supply pressure to air knives and blow-off nozzles on a packaging line, keeping sheet and label clearing consistent without overdriving the jets.
Regulate the low-pressure air feeding looms and textile processing heads, where delicate pneumatic components need a limited, closely held setting below 0.4 MPa.
Start with the port step: the 300 size takes a 3/8 in port, and larger sizes carry more flow - but since GR flow is published as curves rather than a single rating, tell us your air demand and we will confirm the right size from the datasheet. This unit is the low-pressure (L) type with a setting range up to 0.4 MPa; if your process needs settings above that, the standard GR type covers up to 0.9 MPa. The fitted square gauge reads in psi; external round gauges and MPa or bar scales are available. Thread here is NPT (T code), with PT as the standard and G also orderable. A bracket is included, and GR is also panel-mountable; a reverse/check valve (K) can be specified if you need one-way protection.
Quick checklist
Without a reflux valve, air cannot flow back through the regulator — order the K option if reverse flow is required. A regulator does not remove water or particulate; that is the filter's job.
AirTAC publishes GR flow as curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure, required downstream setting and air demand, and we will confirm the flow from the datasheet and check the 300 size against your application before you order.
The L in the code marks the low-pressure type, whose setting range tops out at 0.4 MPa - chosen for processes that must not see higher line pressure. The F2 in the code fits the embedded square gauge with a psi scale; MPa or bar scales and an external round gauge are available as options.
