Engineered for superior filtration, faster lautering, and world-class hygiene — built with Apollo’s large-format manufacturing technology up to 14,000 mm diameter.
Apollo False-Bottom Wedge Wire Screens are precision-engineered lauter tun and mash tun filtration floors made from premium stainless steel.
Compared to perforated plates, Apollo’s V-wire profile delivers:
Typical slot size: 0.5–1.0 mm, depending on grist type.
| Application Segment | Applications |
|---|---|
| Breweries & Distilleries |
• Lauter tun false bottoms • Mash tun floors • Decoction mash mixers • Extractor vessels |
| Food & Biotech |
• Steeping tanks • Leaching systems • High-purity filtration vessels |
| Process Engineering |
• False floors • Drainage decks • High-flow extraction platforms |
| Feature | Description |
|---|---|
| ✔ Superior Filtration & Clean Wort | Fast drainage with reduced solids carry-over. |
| ✔ Non-Clogging V-Wire Geometry | Self-cleaning slots prevent blinding and downtime. |
| ✔ Heavy-Duty, Compression-Resistant Build | Supports large grain loads and rake systems without deformation. |
| ✔ Higher Effective Open Area | Long continuous slots deliver higher flow than perforated plates. |
| ✔ Consistent Slot Size Over Time | CNC welding prevents slot widening and ensures stable clarity. |
| ✔ Hygienic & Maintenance-Free | Ra ≤ 0.8 µm finish, food-grade passivation, and full CIP/SIP compatibility. |

| Parameter | Apollo Wedge Wire Screen False Bottom | Slotted / Perforated Plate False Bottom |
|---|---|---|
| Filtration Quality | ✔ Very high clarity; continuous V-wire slot gives cleaner wort with minimal husk carry-over | ✖ Lower clarity; larger slot edges allow husk and fine solids to pass |
| Flow Rate / Drainage Speed | ✔ Faster lautering due to higher effective open area & uniform slots | ✖ Slower; open area is limited and non-uniform |
| Clogging / Blinding | ✔ Non-clogging V-wire geometry; self-cleaning action | ✖ Slots clog easily; blinding increases lautering time |
| Slot Accuracy & Stability | ✔ CNC-welded slots remain stable over years | ✖ Slots deform, widen with time, affecting run-off quality |
| Strength & Structural Integrity | ✔ Heavy-duty resistance-welded structure; handles large grain loads and rake pressure | ✖ Weaker; flat perforated plates bend under load, causing uneven bed support |
| Hygiene & Cleanability | ✔ Smooth wedge wire surface; easy to CIP/SIP | ✖ More crevices; difficult to clean and sanitize fully |
| Lifetime / Durability | ✔ Very long service life (5–10+ years) | ✖ Shorter life due to cracking, deformation, and corrosion |
| Open Area % | ✔ High; continuous narrow slots maximize flow | ✖ Limited by hole/slot punching process |
| Pressure Drop | ✔ Lower ΔP due to tapered slot geometry | ✖ Higher ΔP; turbulent flow through punched slots |
| Build Options | ✔ Custom diameter up to 14,000 mm; panels or one-piece discs | ✖ Limited sizes; not suitable for mega-brewhouse diameters |
| Maintenance Requirements | ✔ Minimal | ✖ Frequent cleaning and higher downtime |
| Consistency of Lautering | ✔ Uniform bed formation; smoother lautering cycles | ✖ Bed becomes uneven due to plate deformation |
| Food-Grade Surface Finish | ✔ Ra ≤ 0.8 µm, ASTM A967 passivated | ✖ Basic industrial finish; rougher surface |
| Cost-to-Performance Ratio | ✔ Higher initial cost, but much lower lifetime cost | ✖ Cheaper to buy, expensive to maintain and replace |
