FILTR TECHNOLOGIES LTD

What FILTR TECHNOLOGIES LTD does

Filter Technology Ltd. is a privately held, founder-owned industrial air filtration and pollution control systems manufacturer founded in 1991 by Bob Hood and headquartered in Lake Crystal, Minnesota, with a West Coast office in Milwaukie, Oregon. The company designs and builds custom air pollution control systems — including baghouse dust collectors, cyclones, multiclone collectors, air-to-air heat exchangers, carbon absorption beds, fiber bed filters, bin vents, and ducting — for industrial manufacturers and processors across industries such as mining, agriculture, chemical, pharmaceutical, cement, and wood products, with documented installed equipment on six continents. Its specialty is high-temperature filtration, with more than 25 heat exchangers in service and 15 units operating at 1,600°F furnace exit temperatures on silica dust applications, supported by a proprietary expansion joint design at the cell plate of heat exchangers.

The business operates as a turn-key direct-sales operation using a consultative engineering model. Customers initiate contact via website quote requests, the company's engineers scope and design custom systems, fabrication is handled through a network of trusted U.S. fabricators, and Filter Technology manages installation and ongoing service. Revenue is generated from one-time equipment sales, recurring parts and maintenance (including for builds by other manufacturers), and engineering/consulting services such as system evaluation, EPA compliance, and permit acquisition; pricing is quote-based and not publicly disclosed. The headcount of 1-10 employees reflects a lean operation centered on engineering expertise and an outsourced fabrication model rather than internal manufacturing scale.
