Overview
The Arrow SQF-2 is an economy-class Super Quiet Flow muffler for 1/4″ NPT pneumatic exhaust applications. Built with a self-cleaning, stainless steel screen element housed in ultrasonically welded glass-filled nylon, the SQF-2 delivers effective noise reduction while preserving airflow efficiency. This package includes five individual mufflers, ideal for multi-cylinder, multi-valve, or distributed exhaust-point installations in pneumatic machinery.
