Balston 100-12-BX Filter Cartridges

Balston 100-12-BX is a replacement coalescing filter cartridge for Balston two‑stage compressed air filtration systems. In the standard Balston filtration sequence, it serves as the second stage after a Grade DX prefilter (100-12‑DX) and precedes the final membrane stage (for example GS‑100‑12‑95), forming a DX→BX→final membrane arrangement that Balston documents for optimal liquid and aerosol removal from instrument and plant air. Two‑stage filtration is recommended, with BX intended to be used in conjunction with a preceding DX cartridge rather than alone. These BX cartridges are designed for Balston‑branded filter housings and are not interchangeable with non‑Balston elements if maintaining specified performance. Maintenance guidance for this configuration commonly aligns with a roughly six‑month replacement interval for the DX and BX stages, reflecting Balston’s service schedules in documented configurations.
