Product behaviour
Vacuum level filling should be assessed against bottle rigidity, liquid viscosity, foaming, neck size and required appearance. It is especially useful where exact internal bottle volume varies.
Vacuum level fillers
Vacuum level filling machines fill to a visual level rather than a set volume. This can be useful for glass bottles and premium packaging where presentation on the shelf is important.

Specification guide
Use these notes to narrow the specification before requesting a quotation.
Vacuum level filling should be assessed against bottle rigidity, liquid viscosity, foaming, neck size and required appearance. It is especially useful where exact internal bottle volume varies.
Confirm bottle, jar, vial, bucket or jerrycan dimensions, neck opening, fill volume range and whether the same machine must cover multiple formats.
Daily volume and containers per minute decide whether a compact, semi-automatic or fully automatic configuration is the sensible starting point.
Product-contact parts, hose sets, hopper design and tool-free changeover can make a major difference when products or container sizes change regularly.
Applications
Lancing can review the product, container and target output to recommend a practical machine configuration rather than a generic one-size-fits-all filler.

FAQ
The main details are product name, viscosity, fill volume, container dimensions, closure type, required output, cleaning requirements and whether the liquid is foamy, corrosive, flammable, hot-filled or hygienic.
Yes. Lancing can discuss semi-automatic, compact and fully automatic configurations depending on output target, operator involvement and future production plans.
The best method depends on product behaviour. Thin liquids, viscous products, foamy liquids, corrosive chemicals and high-value small fills may each need a different filling principle.
