JS-GF01 | Gravity Flow Filling System | 304 Stainless Steel | CE Certified
Water, juice, alcohol, and other thin, free-flowing liquids don't need — and shouldn't be run through — a piston or pump-driven filler. Gravity filling uses the liquid's own flow under a consistent head pressure to fill each container, which is simpler mechanically, easier to clean, and better suited to high-speed lines for liquids that already flow well on their own. The JS-GF01 is built specifically for that category of product.
Purpose-built for free-flowing liquids — gravity filling lets thin liquids (water, juice, spirits, vinegar-based liquids) fill naturally through consistent liquid-level control, without the mechanical complexity or clog risk that piston/pump systems can introduce with thin products
Adjustable filling capacity — the filling volume is configurable to your container size and product, rather than fixed to a single range, so the same base machine can flex across your product lineup
±1% filling accuracy — despite the simpler mechanical principle, servo-assisted level control keeps fill consistency tight across a full run
304 stainless steel construction — corrosion-resistant and cleanable to the standard food and beverage lines require for products with direct human consumption contact
Expandable to multi-nozzle configuration — 2-6 nozzle configurations available for higher throughput on high-volume beverage or water lines
CE certified, OEM/ODM customization available — configurable nozzle count, conveyor integration, and motor brand to match your line layout

Gravity filling relies on the product's own flow characteristics, so it's the right principle when your liquid moves freely and consistently without external displacement force:
Liquid Type | Typical Products | Why Gravity Filling Fits |
Water-based liquids | Purified water, mineral water | Flows freely and consistently — no need for mechanical displacement |
Beverages | Juice, tea, soft drinks | High-speed compatible; simpler mechanism means easier CIP/cleaning between product changeovers |
Alcohol & spirits | Alcohol, liquor, vinegar-based liquids | Low viscosity flows evenly through gravity head; 304 stainless steel resists most alcohol-based corrosion |
Other free-flowing liquids | Thin oils, diluted liquid products | Suitable as long as viscosity stays low and consistent |
If your product is thick, pasty, or doesn't flow easily on its own — cream, honey, thick sauces, shampoo — gravity filling will underperform or fill inconsistently. In that case, our piston filling machine is the better-suited option. We'll tell you directly which principle fits your product rather than fit your product to whichever machine we're trying to sell.
Beverage & Water — purified/mineral water, juice, tea, soft drinks
Alcohol & Spirits — liquor, alcohol-based liquids, vinegar products
Food — thin liquid condiments and free-flowing food liquids
Daily Chemical — thin liquid cleaners and low-viscosity chemical liquids (consult us for chemical compatibility)
The JS-GF01 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. High-volume water and beverage lines in particular benefit from pairing this machine with a capping and labeling module for a continuous run. If you're planning a full line rather than a single machine, tell us your target throughput and we'll map out the line configuration.
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
Configurable, not one-size-fits-all — nozzle count, conveyor integration, and motor brand are configured around your actual line, not sold as a fixed catalog spec
After-sales support that doesn't route you through a queue — online technical support, remote troubleshooting, installation guidance, and overseas engineer service upon request
1. What types of liquids can the JS-GF01 handle?
It's built for thin, free-flowing liquids — water, juice, alcohol, spirits, and similar low-viscosity products. If your product is thick or paste-like (cream, honey, thick sauces, shampoo), a piston filling machine is the better-suited option — we can point you to that instead.
2. What is the filling accuracy?
Servo-assisted level control keeps filling accuracy within ±1%, consistent across a full production run.
3. What fill volume range does it support?
Filling capacity is adjustable and configured to your specific container and product — there's no fixed range built into the base machine. Tell us your target volume and we'll confirm the configuration.
4. What bottle or container types are compatible?
The JS-GF01 works with round, square, oval, and flat containers in PET, HDPE, glass, or other rigid packaging, and can be adjusted for different container sizes. Send us your container photo and dimensions for a fit confirmation.
5. Can I get a higher-speed, multi-nozzle version?
Yes. The gravity filling platform is expandable to 2-6 nozzle configurations for higher throughput on high-volume beverage or water lines. Let us know your target speed and we'll recommend the right nozzle count.
6. Can this be integrated into a full production line?
Yes. The JS-GF01 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 container photo and dimensions, the product you're filling, target fill volume, required production speed, and container material. Sample containers are helpful if available.
8. What after-sales service is included?
A 1-year warranty, online technical support, installation guidance, operation manuals, spare parts supply, remote troubleshooting, and overseas engineer service upon request.
Tell us your product, container, and target output speed, and our engineering team will confirm whether gravity filling is the right principle for your line — and configure the JS-GF01 to match.
