X PACKS - 1" 2" 3.5"

Overview

X Packs are high-performance, spherical Tri-Pack style random packing media engineered to maximize gas-to-liquid contact in mass-transfer applications. Available in three nominal sizes — 1″, 2″, and 3.5″ — X Packs are designed for use in wet scrubbers, air strippers, absorption and stripping columns, odor control systems, and water treatment applications.

Each size is stocked in both General Purpose Polypropylene and NSF-Certified Polypropylene formulations for potable water and food-contact applications. Glass-Filled Polypropylene and PVDF materials are also available for elevated-temperature and specialized chemical service requirements.

Why X PACKS Work

Maximum gas-to-liquid contact. The open-lattice sphere exposes media surface in every direction, improving mass-transfer efficiency over conventional ring and saddle media.
High void space, low pressure drop. Up to 96% void space helps deliver stable operation with minimal fan power — even in tall, high-velocity columns.
Spherical geometry, uniform wetting. Every piece is symmetric — so it lands the same way every time, with predictable distribution and no orientation effects.
Durable injection-molded construction. Manufactured in-house with 36+ years of tooling and production experience.

Packaging & Shipping

X PACKS ship from stock in standardized packaging configurations designed to simplify handling and reduce freight costs.

Our 1″ X PACKS are palletized in 50 ft³ quantities and packaged in 5 ft³ boxes. The 2″ and 3.5″ X PACKS are palletized in 120 ft³ quantities and packaged in 10 ft³ boxes for efficient storage and transportation.

For high-volume applications, our 2″ and 3.5″ media are also available in 60 ft³ super sacks.

Independently Tested

X PACKS have been independently characterized by a third-party engineering firm — geometric surface area, void fraction, pieces per ft³, and full pressure-drop curves measured across all three sizes. That data, along with our current cut sheet and chemical compatibility information, is available to qualified buyers on request.
