About the Airtac GTFR Filter Regulator GTFR20008LJWK
GTFR20008LJWK adds the K option to the low-pressure GTFR200 build: a check valve in the 1/4 inch (08) PT flow path that blocks reverse flow when upstream supply drops, holding the regulated pressure on the downstream side. The L setting covers 0.15 to 0.4 MPa (20 to 58 psi), and the W option fits the 5 um element in place of the standard 40 um.
The unit belongs to the GT200 series, the short-PC-bowl version of the GA200, so it fits enclosures where a full-length bowl will not go. Drain is differential plus manual, a pressure gauge is fitted, and the J option means no mounting bracket ships with the unit.

How to choose
Pick GTFR20008LJWK over GTFR20008LJW when the downstream circuit must keep its set pressure through a supply interruption, which is exactly what the K check valve does. Drop the K if backflow retention is irrelevant, or move to GTFR20008LK to regain the included bracket and accept the standard 40 um element; GTFR20006LJWK offers the same feature set on a 1/8 inch port.
Applications
Low-pressure clamping that must hold
The K check valve keeps the regulated side charged when plant supply blips, so clamps and grippers running at 0.15 to 0.4 MPa (20 to 58 psi) do not relax mid-cycle.
Forming and sealing heads
Stations needing fine 5 um air at low pressure get both in one body, with the gauge making the setpoint visible on the line.
Skid and cart-mounted equipment
With no bracket (J) the unit is fixed directly to the skid frame, and the differential plus manual drain of the short PC bowl clears condensate between moves.
FAQ
What are the key figures of the GTFR20008LJWK?
Port 1/4 inch (08), PT thread; low-pressure type regulating 0.15 to 0.4 MPa (20 to 58 psi); 5 um element (W); check valve (K); pressure gauge fitted; no mounting bracket (J); short PC bowl with differential plus manual drain.
What does the check valve change in practice?
It lets air flow from the regulator to the circuit and stops reverse flow when upstream pressure falls, so a supply interruption does not dump the regulated low-pressure side. If your process tolerates a pressure dump, the same build without K is GTFR20008LJW.
