LANPAC-XL® High Efficiency Tower Packing

Four-Layer Construction

LANPAC-XL and Q-PAC share the same fundamental architecture: stacked rod-grid layers that create drip points for breaking liquid streams into fine droplets. The difference is depth. Q-PAC uses three layers; LANPAC-XL uses four. Each additional layer contributes its rod population to the total, compounding the drip point density that drives mass transfer performance.

This construction principle — impossible in single-piece injection molding — is what separates the LANPAC-XL/Q-PAC family from conventional random packings. The drip points fill three-dimensional space with droplets, presenting their entire surface area to the gas phase rather than spreading liquid across two-dimensional plastic surfaces.

The Right Tradeoff

Higher drip point density means more gas-liquid contact per cubic foot, but also somewhat higher resistance to gas flow. LANPAC-XL operates at the high-efficiency end of the pressure drop/mass transfer curve — shorter beds, more work per unit depth, higher total pressure drop than Q-PAC at equivalent bed volume.

This makes LANPAC-XL the natural choice for:

• Air strippers where tower height drives project cost
• Degasifiers targeting aggressive dissolved gas specifications
• Biological treatment systems requiring maximum surface area for biofilm development
• Any application where the blower can handle additional head and bed depth is the constraint
