Active pharmaceutical ingredients industrial processing

Cipla Ltd in India relies on the revolutionary Russell Compact Airlock Sieve® to ensure its new plant meets the highest OEL standards ensuring a safe screening operation

Minimizing operator risk is essential when processing active pharmaceutical ingredients (API’s). The occupational exposure limit (OEL) must be met to prevent inhalation of harmful vapors or dusts. When Cipla Ltd built its OEL-compliant plant at its Goa factory in 2005, a screener to safeguard product quality and prioritize operatory safety was needed. The process involved the removal of oversize from incoming raw materials, and undersized particulates after granulation. Cipla attended an exhibition where it discovered the OEL level 5 compliant Russell Compact Airlock Sieve™.


Using a pneumatic clamping system, combined with patented Twist Lock Inflate (TLI) technology, the vibro sifter provides a dust-tight seal, minimizing chemical exposure. This system also allows easy assembly and disassembly of the product contact parts without any tools. Components are simply placed into the base and secured by twisting and locking the lid. The machine is then sealed by inflating the airclamp. In addition, different products can be screened on the same unit due to its simple design which lends itself to quick cleaning and disassembly.

What our clients say

“During initial product trials, we recognized how the new Airlock screener utilizes the Russell Compact technology to increase screening efficiency allowing even sticky products to be sieved without blinding. Also, due to its new clamping system, it is extremely easy to dismantle when compared to conventional clamping methods. It is clear that this particular unit has been designed specifically for this type of application.”
