The Code 7 Advantage: Preventing Product Bypass

Standard double-open-end filter cartridges work fine for general utility lines, but they carry a major risk in sanitary applications: bypass. If an operator improperly seats an element or a gasket shifts during a temperature spike, unfiltered liquid can slip past the seal.

Hy-SanX™ Code 7 Filter Cartridges utilizes the secure Code 7 design to completely eliminate this vulnerability.

• Dual O-Ring Base: Two dynamic locking rings create a tight, leak-proof compression seal inside the housing sleeve.
• Locking Bayonet Tabs: A simple twist locks the element firmly into place, preventing it from lifting or shifting under pressure surges.
• Pointed Spear Tip: The top fin aligns perfectly with the housing guide plate to ensure uniform flow distribution across the entire filter matrix.

Precision Micron Options for Sterilization and Clarity

Different stages of beverage production demand different levels of filtration. To cover your process loop from pre-filtration through final packaging, the Hy-SanX™ Code 7 Filter Cartridges series is manufactured in specific micro-ratings:

• 0.2 Micron (Absolute Membrane): These options function as an absolute microbiological wall. They are commonly used for the cold sterilization of bottled water, beer, and wine, successfully trapping stubborn spoilage organisms like Brevundimonas diminuta, wild yeasts, and lactic acid bacteria without stripping essential color or flavor profiles.
• 0.5 and 1.0 Micron (High-Capacity Pleated Depth): Ideal for final clarification and polishing. These elements catch fine hazes, residual yeast cells, and unstable proteins, giving spirits, juices, and syrups a crystal-clear, shelf-stable appearance.

Material Formulations for Food Safety Compliance

Every component of the Hy-SanX™ Code 7 Filter Cartridges element is selected with strict consumer safety in mind. The media matrices, support layers, and structural cages are constructed from 100% polypropylene or polyethersulfone (PES) polymers that meet FDA requirements for food contact.

The entire element assembly is thermally bonded without the use of glues, resins, or chemical binders. This specialized manufacturing technique guarantees that the Hy-SanX™ Code 7 Filter Cartridges will not introduce trace extractables or alter the natural taste, aroma, or mouthfeel of your beverage.

Built for Aggressive Sanitation Cycles

Sanitary filters must be able to withstand the repeated thermal stress of Clean-In-Place (CIP) regimes. A delicate filter element will warp or tear after just a few hot water flushes. The structural outer cage and inner core of the Hy-SanX™ Code 7 Filter Cartridges are heavily reinforced. This allows the element to maintain its physical integrity during repeated hot water sanitation cycles and in-line steam sterilization up to 135°C (275°F). This structural durability ensures you get maximum processing life out of each element before needing a replacement.

Frequently Asked Question

Here are the most common questions quality control managers, brewmasters, and plant engineers ask when implementing the Hy-SanX™ Code 7 Filter Cartridges in their production lines.

Q: What makes a Code 7 connection better than standard flat-gasket filters for beverage processing?

Standard flat-gasket filters rely entirely on downward spring pressure to seal. If the filter housing suffers a pressure spike or a thermal shock during cleaning, the cartridge can shift, allowing bypass. The Code 7 design features an locking bayonet base with two 226 O-rings. It twists and locks securely into the housing grid. This mechanical lock cannot back out or lift, guaranteeing a perfect, bypass-free seal even during aggressive process pressure upsets.

Q: Can the Hy-SanX™ Code 7 Filter Cartridges 0.2-micron filter be trusted for true cold sterilization?

Yes. Our 0.2-micron absolute-rated polyethersulfone (PES) membrane is specifically engineered and validated to serve as a sterile biological barrier. It reliably traps common beverage spoilage organisms, wild yeasts, and harmful bacteria (such as Brevundimonas diminuta) without stripping away the natural color, aroma, or flavor compounds of your product.

Q: Are these filters safe for direct food and beverage contact?

Absolutely. Every single component used to build the Hy-SanX™ Code 7 Filter Cartridges including the filtration media, support layers, structural cage, and end caps—is manufactured from 100% FDA-listed polymers. Furthermore, we construct these elements using thermal bonding techniques without any adhesives, glues, or chemical binders, ensuring zero flavor crossover or extractables in your product stream.

Q: Can I run these cartridges through hot water CIP or steam cycles?

Yes, the Hy-SanX™ Code 7 Filter Cartridges series is engineered specifically to handle repeated sanitation cycles. The reinforced internal core and outer protective cage prevent the pleated media from warping under thermal stress. The elements can safely withstand in-line steam sterilization or hot water sanitization routines up to 135°C (275°F).

Q: How do I choose between the Polypropylene (PP) and Polyethersulfone (PES) media options?

• Choose PP Pleated Depth (0.5 and 1.0 micron): For pre-filtration, bulk yeast removal, and final polishing. These have high dirt-holding capacity and are perfect for giving beer, wine, or spirits a brilliant visual clarity
• Choose PES Membrane (0.1 and 0.2 micron): For your final, critical terminal filter step directly before the bottling or kegging line where absolute microbial security is required.

Q: What is the recommended change-out differential pressure (ΔP)?

For normal operation, we recommend changing out the elements when your differential pressure reaches 2.4 bard (35 psid). However, in many sanitary facilities, elements are swapped on a strict time-based schedule or after a set number of CIP cycles to maintain total biological security and prevent particulate unloading.
