Good Health Starts with AAF OptiFlo®

The pharmaceutical industry presents a unique challenge regarding dust collection. Many of the materials involved in pharmaceutical production can be harmful to workers. Additionally, the industry is driven to guarantee the purity of their products; so any source of contamination must be contained and eliminated. Furthermore, the compounds involved are often organic in nature, making them highly combustible. In penicillin production specifically, dust is usually an issue in the post-drying part of the process. At this stage, the dried penicillin is in the form of a very fine powder, which can be dispersed easily when transferred.

The challenge for any dust collector in the pharmaceutical industry is to protect workers’ safety and to guarantee the product’s purity by capturing process-generated dust while minimising the risks of an explosion/ deflagration. A Bag-In/Bag-Out (BIBO) arrangement dust collector with explosion vents helps to meet this challenge. The BIBO arrangement allows workers to change out filters and remove collected dust without the risk of exposure to the potentially hazardous dust. By providing an OptiFlo® with the Bag-In/Bag-out feature, AAF makes sure the pharmaceutical dust is fully contained safely.

Challenge

Through the movement and transfer of materials, the plumes of hazardous particles were generated where workers were present.  In pharmaceutical processes, it is highly important to collect and contain particulates as they may be hazardous. It is crucial to provide the customer a solution that answers the primary concern without causing the pharmaceutical manufacturer additional maintenance requirements or steps in their process.

Solution

Using  a  well-designed hood  with  over  4,000  fpm carrying velocity in the inlet ductwork, AAF provided essential proper ventilation to the manufacturing process to capture any nuisance particulates. A highly efficient REDClean®  N, a nanofibre layered filter rated initially at MERV 15+, made sure that even sub-micron particles were cleaned from the airstream. AAF® supplied  these  filters in  an  OptiFlo®   cartridge collector with Bag-In/Bag-Out (BIBO) design. The BIBO arrangement made sure that workers would be kept safe from harmful contaminants that are captured by the collector as the BIBO procedure allows filters and barrel changes without exposure to dirty air.

Benefits

The full containment of the pharmaceutical particles is extremely critical in a production process. The dust collector system should have a  high-efficiency filter, but  also maintain a  complete  barrier from  workers when doing any maintenance, such as replacing filters and removing the collected dust from the unit. With the OptiFlo®’s BIBO design, AAF provided a complete solution to fulfil the pharmaceutical customer’s needs.
