Piggyback Air Filter-Regulators

Ingersoll Rand manufactures a range of Standard Filter Regulators, which are "piggyback" units that efficiently combine filtration and regulation functions. These robust units are available in various pipe sizes, typically including 3/8", 1/2", and 3/4" with NPT and BSP thread options, providing versatile integration into pneumatic systems. Known for their industry-leading flow rates and low leak rates, these regulators ensure efficient and reliable air preparation for diverse pneumatic equipment. Featuring an all-modular design, often with polycarbonate locking bowls for enhanced safety and bright, flush-mount gauges, these filter regulators are built for durability, easy monitoring, and long-term performance.
