Compact airlock sieve

The new Compact Airlock Sieve, from separation and filtration specialist Russell Finex, is said to be the first real advance in pharmaceutical sieving technology for ten years.

Designed in consultation with leading pharmaceutical companies, the Airlock Sieve features a validatable pneumatic clamping system that gives significant improvements in powder containment and operator health and safety.

The operation of the Compact Airlock Sieve is simple. Oversize contamination is removed by a mesh screen fitted to the unit, while the good product passes through the mesh and on to the next stage of production.

The design of the screener is based on clean lines making sanitation easier and performance greater. Clean down times are reduced, as the sieve can be disassembled in seconds without the need for tools. Crevice free and smooth surfaces make the product contact parts easy to clean.

The unit is clamped together with its airlock system. This pneumatic lock gives an even and high clamping force across all sealing faces and therefore guards against powder leakage more effectively than traditional band clamps or over-centre toggle clamps.

Assembly of the screener is achieved by placing the component parts into the base and locating them by twisting and locking the lid – there is no need for tools. The airclamp is then inflated to secure and seal the unit during operation.

The pneumatic clamping system can itself be FDA validated to provide a measurable seal. ATEX-compliant, the Compact Airlock Sieve is available with a range of options.
