Custom Work in the Field
Three examples of custom filtration problems Airsan has solved — each one documented in a full case study.
Desert Power Generation
A blower and fan systems manufacturer needed 6,000 CFM of filtration for a Middle East power-generation installation — arid climate, high dust, abrasive particulate. Airsan engineered its largest cylindrical filter, over 30" in diameter and 30" tall, with reinforced media to prevent collapse while maintaining efficiency.
Read the case study →Aircraft Carrier Launch System
A US military supplier replacing steam catapults with the electromagnetic EMALS launch system needed filtration for its electronics and power storage systems. Airsan’s Type KK filter — military-grade, permanent dry-type construction — was chosen to protect the ventilated equipment.
Read the case study →Rail Industry Valve Manufacturer
A valve body manufacturer faced clogging in vacuum relief valves for locomotive tank cars. Airsan worked through design, test, and implementation of a custom solution — zero failures since, and streamlined production cut the customer’s unit cost by more than 15%.
