JS-AF01 | Overflow Level-Control Filling System | For Glass & Transparent Bottles | CE Certified
Glass and other transparent bottles expose a filling problem that opaque containers hide: any variation in fill level is immediately visible to the end customer, and glass bottles themselves often have small dimensional variances batch to batch that make volume-based filling inconsistent to the eye. Overflow filling solves this by filling to a constant liquid level rather than a fixed volume — so every bottle looks identically filled on the shelf, regardless of small differences in bottle capacity.
Fills to a constant level, not a fixed volume — this is the core advantage for transparent packaging: overflow filling compensates for bottle-to-bottle dimensional variance, so fill height looks uniform even when bottle capacity varies slightly
Purpose-built for glass and transparent bottles — where visible fill-level consistency matters more to buyers than it does with opaque or labeled packaging
Well suited to water, alcohol, and spirits — the liquid categories most commonly packaged in clear glass where shelf appearance is part of the product's premium positioning
304 stainless steel construction — corrosion-resistant and cleanable for beverage and alcohol production standards
CE certified, OEM/ODM customization available — configurable nozzle count and motor brand (Delta / Panasonic / Siemens available) to match your bottle line

Note on specifications: Exact fill volume range, power rating, air pressure, and machine footprint for the JS-AF01 are configured to your specific bottle shape and target line speed — overflow filling performance is more bottle-shape-dependent than piston or gravity filling, so specs are confirmed against your actual container rather than a single fixed spec sheet. Send us your bottle dimensions and target output, and we'll confirm exact specifications.
Liquid / Container Type | Typical Products | Why Overflow Filling Fits |
Glass bottles | Spirits, liquor, premium water, glass-bottled beverages | Constant fill level hides bottle-to-bottle capacity variance that's common with glass |
Transparent plastic bottles | Clear PET water or beverage bottles | Same visible fill-level benefit as glass, for clear packaging |
Water | Purified/mineral water in glass or clear PET | Free-flowing liquid works naturally with overflow level control |
Alcohol & spirits | Liquor, spirits, wine-adjacent products | Premium packaging segment where shelf appearance is part of the product's value |
If your bottles are opaque or your priority is precise volume accuracy over visual level consistency, a gravity or piston filling machine (depending on your product's viscosity) is likely a better fit — see our gravity filling machine page for free-flowing liquids in non-transparent packaging.
Alcohol & Spirits — liquor, spirits, and other premium glass-bottled beverages
Beverage & Water — glass or clear PET-bottled water and beverages
Food — clear-bottled liquid condiments where fill-level appearance matters
The JS-AF01 integrates with upstream and downstream equipment — bottle unscramblers, capping machines, labeling machines, inkjet coders, and carton packing systems — to form a complete automatic filling line. Glass bottle lines in particular often need careful integration with capping and labeling stations tuned for glass handling — let us know your full line requirements and we'll help configure compatible equipment.
Full lifecycle service — from technical consultation through installation, long-term maintenance, and spare parts supply, not just a one-time equipment sale
CE certified, ISO-aligned manufacturing — built to meet the compliance expectations of North American, Western European, Southeast Asian, and Australian buyers
Configured around your actual bottle, not a generic spec — because overflow filling performance depends heavily on bottle shape, we confirm specs against your real container dimensions rather than offering one fixed configuration

1. What makes overflow filling different from other filling methods?
Overflow filling fills to a constant liquid level rather than a fixed volume. This means the fill height looks consistent bottle to bottle even if there's small variance in bottle capacity — which matters most with glass and transparent packaging where fill level is visible to the end customer.
2. What bottle types work best with this machine?
Glass bottles and other transparent or clear packaging are the primary use case, since that's where visible fill-level consistency provides the most value. It also works with opaque bottles, but a gravity or piston filling machine may be more cost-effective if visual level consistency isn't a priority for you.
3. What is the filling accuracy?
Overflow filling optimizes for consistent visual fill level rather than pure volumetric precision. Accuracy is up to ±0.5% under standard conditions, but if your priority is strict volume accuracy over visual consistency, a gravity or piston system may suit you better depending on your liquid's viscosity.
4. What is the production capacity?
Standard configurations run 20-120 bottles/min depending on bottle size and nozzle count, with higher-speed custom solutions available.
5. What liquids can this handle?
Overflow filling works best with free-flowing liquids — water, alcohol, spirits, and similar low-viscosity products commonly bottled in glass.
6. Can this be integrated into a full production line?
Yes. The JS-AF01 can connect with bottle unscramblers, capping machines, labeling machines, inkjet printers, and carton packing equipment to build a complete automatic filling line.
7. What information do you need to recommend the right configuration?
Please share: your bottle photo and dimensions (bottle shape variance matters especially for overflow filling), the product you're filling, target fill level, and required production speed. Sample bottles are especially helpful for this filling type.
8. What after-sales service is included?
A 12-month warranty, online technical support, installation guidance, operation manuals, spare parts supply, remote troubleshooting, and overseas engineer service upon request.
Send us your bottle dimensions and target liquid, and our engineering team will confirm whether overflow filling is the right approach for your line — and configure the JS-AF01 to match your exact container.
