Pass-through systems

Alflow sells single-use pass-through systems for the pharmaceutical industry. It is a practical, safe and easy way to move large quantities of liquids from one room to another without risk of breakage, contamination or spillage. This ensures that the sterile barrier is preserved so that the qualification is maintained.

With pass-through systems, you achieve flexibility in terms of design, as they can be used for both new and existing facilities. It is also possible to pass a single or several tubes of different sizes through the same portal.

What are pass-through systems?

Pass-through systems are a safe, aseptic solution for transferring liquids between two different classes of cleanrooms. The systems are specially manufactured so that they can be adapted to different wall thicknesses. They can also be adapted for floor-to-ceiling conveyance. They can also be used for new or existing facilities, which offers great flexibility in terms of the design.

As the first and only system of its kind, our pass-through systems can manage several tube openings and cleaning ports through a single wall portal. They can also save you a lot of money compared to other pass-through methods that contain numerous moving parts and require frequent and expensive maintenance.

Find the right pass-through system for your application

Our pass-through system is a patented system that provides a practical, safe and easy way to move large volumes of liquids from one room to another without risk of damage to the container or loss of product. The system’s incorporation of disposable components for single use also eliminates cleaning-validation requirements involving expense, waste of time, labour and natural resources.

The pass-through systems use 316L stainless steel components such as portals, end caps and hygienic union clamps to form a secure barrier while incorporating single-use hoses, seals and insulator assemblies for the fluid-transfer processes. The systems are offered in standard sizes up to 6” diameter, and larger dimensions are available on request.

The concept of single or multiple tubing ports, where one pass-through system can serve several different tubes, is unique to our pass-through system. You can choose from aseptic or open connector configurations that can be adapted to your process. Single or double isolation barriers maintain the proper environment, while purge ports introduce filtered air, creating a portal under pressure for complete isolation between classified areas.

The use of single-use components eliminates the need for production stoppages for the purpose of sterilisation, reduces the risk of contamination, and increases efficiency. The single-use systems simplify the cleaning validation in that they are used once and then discarded. By doing so, they reduce the end user’s labour costs and time, while saving energy and resource costs by eliminating the need for cleaning and autoclaving after each batch.

Single-use systems provide flexibility and speed in facility design, as system conversions are implemented faster than with hard stainless steel piping. They also provide less costly process development and design compared to steel systems.
