Ascension Industries
About
Founded in 1956 in North Tonawanda, New York, Ascension Industries is a custom fabrication manufacturer and steward of the Durco Filters brand, which carries over 130 years of liquid-solid separation heritage. Operating from a 100,000-square-foot facility with overhead cranes rated to 50 tons, Ascension produces a comprehensive filtration equipment portfolio. The EP and QP (Quadra Press) filter presses handle batch dewatering of slurries at 3-30% solids with pneumatic or hydraulic closure and optional automatic plate shifting. The TE, PTE, and PVC series tubular backwashing filters provide continuous operation down to 1 micron without interrupting forward flow. Pressure leaf filters are available in horizontal and vertical configurations with wet or dry cake discharge, including the DuraSluice wash system that delivers up to 69% water savings over conventional sluicing. Pressure nutsche filters serve pharmaceutical and specialty chemical batch processing. The Enviro-Dri sludge dryer reduces filter cake weight and volume for inorganic metal hydroxide and hazardous waste applications. Beyond filtration, Ascension manufactures ASME-code pressure vessels up to 13 feet in diameter, skid-mounted process systems with integrated PLC controls, and St. Mary Spin Rolls precision cylindrical grinding fixtures. The company holds ASME U, NB, and R stamps, China Code, European PED, CSA, and ISO certifications, and provides laboratory testing, pilot studies, field service, and 24-hour emergency parts delivery.
