A Guide to Upper Manifolds for Bottle Filling Equipment

In the pharmaceutical packaging world, precision, hygiene, and efficiency are crucial. One of the most overlooked yet vital components in bottle filling manifolds is the upper manifold.

Acting as the backbone of the tablet or capsule dispensing system, the upper manifold ensures even product distribution and alignment, supporting consistent and contamination-free operations. Whether you’re retrofitting an older filling line or upgrading for improved compliance and cleanability, understanding the types and features of upper manifolds can guide you toward better productivity and equipment longevity.

What Is an Upper Manifold?

An upper manifold is a structural component used in slat-style tablet and capsule fillers. It sits above the product channel, dividing and guiding product flow into precise lanes aligned with the bottle infeed system. The manifold’s design plays a critical role in maintaining product integrity, preventing cross-contamination, and supporting cleanroom-grade sanitation standards.

Modern manifolds are engineered not only for performance but also for ease of maintenance and flexibility. As demands for GMP (Good Manufacturing Practice) compliance and equipment versatility continue to rise, the choice of manifold can significantly impact a company’s operational efficiency.

SureFill Style Upper Manifolds: A Modern Approach

The SureFill Style Upper Manifold sets a new standard in pharmaceutical filling technology. Designed with performance, sanitation, and adaptability in mind, this manifold integrates multiple features that align with both regulatory requirements and operational needs.

Quick Disassembly Design

Speed and cleanliness are essential in pharmaceutical environments. The SureFill manifold can be fully disassembled in minutes without the use of tools, making it incredibly user-friendly for routine cleaning and maintenance. Its cleanable surfaces meet GMP requirements, allowing facilities to maintain compliance without interrupting workflow for extended periods.

The inclusion of a flipper actuator further streamlines product control and precision. Additionally, the Teflon hard-coated aluminum construction ensures a long-lasting, non-stick surface, resistant to wear and chemical damage.

Retrofittable Versatility

One of the standout features of the SureFill manifold is its retrofittable design. Whether your facility uses a Merrill, Lakso, King, Speck-Tech Modular, or other filler types, this manifold can be seamlessly integrated, eliminating the need for costly equipment overhauls. This versatility makes it an ideal upgrade for facilities looking to enhance efficiency without investing in a completely new filling system.

Strong Construction

Durability is non-negotiable in high-speed production settings. The SureFill manifold is built with heavy 16-gauge 316L stainless steel dividers, a pharmaceutical-grade material known for its corrosion resistance and cleanability. A four-point positioning system ensures stable alignment, reducing the risk of accidental bending or misalignment that could affect fill accuracy.

Open View and Accessibility

Each lane of the SureFill manifold features an unobstructed open view, allowing operators to monitor tablet or capsule flow in real time. The design also avoids hidden crevices where product residue might accumulate, supporting better sanitation and faster visual inspections.

Standard Style Upper Manifolds: Reliable and Efficient

In addition to the SureFill model, Standard Style Upper Manifolds offer a more traditional solution while still meeting modern packaging needs.

Simple, Cleanable Design

These manifolds feature a minimal parts count, making them easier to clean and reassemble. Like their SureFill counterparts, they are GMP-compliant and built with clear anodized aluminum for corrosion resistance and ease of maintenance.

Compatibility and Retrofitting

The standard manifolds are also compatible with a variety of filler models, including Merrill and Lakso systems. This retrofittable design provides flexibility for manufacturers seeking to update their equipment without compromising existing line configurations.

Industrial-Grade Durability

With the same 16-gauge 316L stainless steel dividers, the Standard Style manifold employs a three-point positioning system to maintain divider alignment. This robust construction minimizes damage from handling and ensures consistent performance in demanding environments.
