Ayater’s 303/383 Series Filter Assemblies deliver exceptional corrosion resistance and precise separation for petrochemical and chemical processing. These ASME Sec VIII Div 1 filter vessels handle hazardous fluids safely, ensuring maximum purity, zero leakage, and compliance with the strictest safety protocols in refinery environments.
Ayater Filtration stands at the forefront of chemical and petrochemical contamination control. Driven by a mission to protect both process integrity and the environment, Ayater invests heavily in R&D to develop corrosion-resistant multi-cartridge housings and advanced filtration media. Our globally recognized footprint ensures that no matter where your refinery or processing plant is located, Ayater provides tailored, fast-tracked delivery of critical filtration assets. Integrity, safety, and innovation define the Ayater promise.
In the volatile environment of chemical processing, standard housings fail. The 303/383 Series ASME Filter Assemblies are engineered by Ayater to thrive where others cannot. Acting as a premium flanged high-flow fluid conditioning unit, this system safely contains and purifies aggressive solvents, petrochemicals, and aqueous chemicals. The interior surfacing and weld integrity are ultrasonically tested to prevent micro-fissures, ensuring that hazardous media never escapes, and output fluid meets the highest purity standards.
Housing Pressure drop is directly proportional to specific gravity.
