The Hanningfield Uni-Vac series of vacuum conveyors are a highly effective and convenient method for the transfer of powder in process applications.
The Uni-Vac offers a dust free method of powder transfer which is vital to the process industries. This approach helps to overcome many problems related to the handling of powder, while also improving overall efficiency and output. The elimination of dust in processing is essential to improving the surrounding working environment and ensuring the integrity of the final product. This automated system negates the need for manual handling whilst offering increased throughput and safety.
Hanningfield is a world class manufacturer of powder handling systems and are proud to support customers in solving their process issues. Our Uni-Vac range of vacuum conveyors have been carefully designed and developed through our 35+ years of experience. The Uni-Vac has been specifically designed with the needs of the end-user in mind.







The Hanningfield vacuum conveyor benefits from an easy-clean design, which allows the system to be dismantled for cleaning without the need for additional tooling. Alongside this, the vacuum conveyor features a crevice-free design, which makes a thorough clean easier. This not only improves hygiene, but also decreases operational downtime by enabling faster cleaning turnarounds. Furthermore, all units are constructed from either 304 or 316 stainless steel to suit your process.
Hanningfield’s knowledge in the application and manufacture of lift systems enables us to provide tailored designs, whereby the vacuum system can be hoist-mounted for increased flexibility. We can also offer static or mobile versions dependent upon your application requirements. In addition to this, our experience with vacuum conveying and size reduction means we have expertise in directly conveying into a cone mill; often known as ‘in-line cone milling’. This can significantly improve both the productivity and hygiene of a process.

Importantly, we are able to remotely locate controls away from the vacuum conveyor itself. Not only does this comply with GMP, but it also offers a hygiene based advantage because the unit becomes easier to maintain and clean.
Our cross-discipline expertise makes us unique in our ability to understand and solve customer problems.
