Parker Hannifin extends process filter range
designed for use in the pharmaceutical processing environment.
They include the ParVent series of validated sterile air filtration products, ParTemp moderate temperature sterilising filters for air and gases, ParTempMAX validated high temperature and high cycle sterilising grade filters, and Sterion PT and PP ultra-high purity polyethersulfone (PES) cartridges for the pharmaceutical, food and beverage industries.
ParVent filters are made of PTFE with polypropylene support construction and are intended for use in fermentation process, sterile tank ventilation and sterilising process exhaust in biological production, according to Parker Hannifin. ParVent construction allows continuous use with temperatures to 160 degrees Farenheit.
Meanwhile, the ParTemp filters have the same construction materials and are also intended for fermentation applications. Their rugged construction allows for up to 50 cumulative hours of steam sterilisation and handles continuous in-service use with temperatures to 176 Farenheit, according to the company.
ParTemp MAX is a high temperature variant that can handle processes up to 221 Farenheit. This temperature stability is achieved by using PTFE with Nomex support layers. ParTemp MAX is designed for high-temperature fermentation applications and can withstand large numbers of steam sterilisation cycles.
Finally, the Sterion PP and PT cartridges are designed to be the final sterilising filter for critical applications in the pharmaceutical, food and beverage industries. Sterion provides absolute micron ratings by using hydrophilic polyethersulfone membrane and polyester upstream/downstream drainage layers. Sterion offers models using dual membrane construction and polypropylene (PP) or polyester (PT) end caps. Dual membranes allow a pre-filtration layer or a secondary barrier to ensure bacterial retention.
