What is the LAS big bag connection system?

The LAS is a flexible, modular connection and emptying system for dust-free emptying of containers with an inliner under containment conditions up to OEB 4.

Which capacities are available for the LAS?

The LAS is available in modular versions for containers up to 500 litres, 1000 litres and 2000 litres.

Can the LAS system be expanded later?

Yes. Thanks to its modular design, the system can be scaled up to a larger version without a full system redesign.

Which containers is the LAS suitable for?

The LAS can be used for big bags, mini bags, drums and other containers with a suitable adapter.

Is an Ex version of the LAS available?

Yes. The LAS can optionally be supplied in an Ex version.

Can the LAS be supplied with WIP or CIP?

Yes. WIP and CIP equipment is available as an option.

Description

The big bag connection system LAS is a flexible, modular connection system from HECHT that enables dust-free high-containment emptying up to OEB 4 of all types of containers with inliner, with a capacity of 500 to 2000 litres. Thanks to the modular design, a customer can start with the Standard variant (up to 500 L) and later scale up to Large (1000 L) or Industrial (2000 L) without a system redesign — ideal for growing or multi-product operations. Special protective films maintain the high containment level even when changing containers, making the system suitable for highly hazardous substances in the food, chemical and pharmaceutical industries. The multi-point coupling interface with double valve isolation per connector provides redundancy: if one connector leaks, the others prevent spillage. Operation is via an ergonomic two-hand lever technique, with optional Ex version, WIP/CIP equipment and endless film port. The system is GMP Annex 1 (2022) compliant, GAMP 5 validatable and has built-in FDA 21 CFR Part 11 logging.

This system effectively protects operators, the environment and products from external contamination and pollution — essential in the pharmaceutical industry. The high containment level is also maintained when changing containers, as special protective films are used. The LAS containment system is particularly suitable for handling highly hazardous substances and demanding applications in the food, chemical and pharmaceutical industries, for example to prevent cross-contamination.

Frequently asked questions about the big bag connection system LAS

What is the LAS large-capacity connection system and why is modularity important?

LAS is a flexible, modular interface for large big bags (up to 2000 L). Modularity is important because: (1) scalable for future growth, (2) cost-effective staging (only buy what you need), (3) clear upgrade path, (4) flexible for multi-product operations.

What is the maximum capacity of the LAS?

Industrial variant up to 2000 L. Modular design means: start small (500 L Standard), upgrade to 1000 L (Large), expand to 2000 L (Industrial) without system redesign.

How does the modular connector system work?

Multi-point coupling interface. Operators connect multiple connectors sequentially (or in parallel for greater flow). Double valve isolation per connector. Redundancy means: if one connector leaks, others prevent spillage.

Is the LAS GMP compliant?

Yes. GMP Annex 1 (2022) compliant, GAMP 5 validation available. Modular design allows validation per module (simpler than monolithic systems). FDA 21 CFR Part 11 logging built-in.

Which big bag capacities does the LAS work with?

Standard: up to 500 L. Large: up to 1000 L. Industrial: up to 2000 L. Modular design = flexible scaling.

How much dust exposure occurs?

>99% dust capture. Double valve isolation per connector. Integrated heavy-duty vacuum recovery. Zero product loss regardless of capacity.

Can I expand the LAS later?

Yes. Clear upgrade path from Standard → Large → Industrial. Modular architecture = swap modules without complete redesign. Future-proof investment.

How much maintenance does the LAS require?

Minimal. Monthly connector inspection. Annual valve seal check per module. Stainless steel housing corrosion-resistant. Very reliable design.

Technology

Two-hand lever technology also allows the liner connection system to be used in the high containment area.
Protective film seals both the product guide tube and the side access port, even without a connected container.
Emptying
- Big Bag Inliner is connected directly to the product guide tube with a connection ring.
- A film bag is attached to the side access spout.
- Contamination-free removal of the residual film from the previous container at the opening of the product guide pipe.
- Fixing of the sealing flange and opening of the big bag outlet for emptying.
Optional WIP or CIP design enables washing and hygienic cleaning of the LAS.
Saves time when changing containers by using a continuous film on the side access port.
