Parker P31 Series Filter-Regulator, G1/4, 0-16 bar, 5µm + Auto Drain
The Parker P31 series Filter-Regulator is part of a comprehensive solution for compressed air preparation. This unit combines particulate filtration and pressure regulation in a single, compact body, minimizing space without sacrificing performance. It is particularly well-suited for low-flow and space-restricted applications.
The product range includes a full complement of particulate and coalescing filters, regulators, filter/regulators, and lubricators. It's available in three body sizes with either BSPP or NPT threading to accommodate various requirements. Individual units can be easily assembled into different combinations using the patented modular system.
