Overview
The Balston 41-070 is a differential pressure indicator designed for monitoring filter condition in compressed air systems. This indicator is used to monitor the pressure drop across filters or other components in a compressed air system, with sensitivity in the range of 0 to 5 psi differential. The 41-070 is a proven accessory for Balston filter assemblies and other pneumatic filter housings operating up to 250 PSIG.
