Parker Balston A915A-DX Pneumatic Filter Assembly

The Parker Balston A915A-DX Pneumatic Filter Assembly is a compact, 10-inch-long filtration unit for compressed-air lines rated up to 250 psig, designed to safeguard downstream components from particulates and oil aerosols. It features 1/2-inch NPT inlet and outlet ports for straightforward integration into standard pneumatic circuitry and is delivered as a complete filter assembly ready for installation. The unit uses Balston’s Grade DX filtration media, offering 0.01 micron filtration with about 93 percent efficiency to remove fine contaminants before they reach sensitive devices. Weighing approximately 2 pounds, this lightweight assembly is appropriate for space-constrained installations in laboratories and industrial environments. Note that Parker Balston has discontinued this model, so availability may be limited through distributors or secondhand channels. Typical applications include protecting pneumatic actuators, sensors, and other precision pneumatic systems where clean air is essential to performance and longevity.
