PSL produces customised sanitary sifters for hazardous materials

Sieve combined with a high containment isolator allows screening of potent compounds to cGMP standards

The Sanitary Sifter by Russell Finex


Customised process equipment manufacturer Powder Systems Limited (PSL) has combined expertise with Russell Finex, separation technology specialists, to create a sieving solution for processing pharmaceutical APIs.

PSL combined its own high containment isolator with the Russell Compact Sieve so users can seive hazardous material and process compounds with an occupational exposure limit of less than 1.0μg/m3.

PSL’s isolator has a half-body suit which allows unrestricted access to the interior of the chamber, whilst ensuring the operator remains safely clear of direct contact with the product.

The Russell Compact Sieves compact design is to allow it to fit comfortably inside an isolator. It is less than half the size of traditional industrial screeners.

This sanitary sifter provides high capacity screening and processing of pharmaceutical powders.

A customised version was manufactured with the sieve motor outside of the isolator, to reduce explosion risk. This was placed in a control cabinet with a plate separating the motor from the sieve.
