What Allegro Industries does

Allegro Industries, founded in 1987 by Tom Johnston and headquartered at 1360 Shiloh Church Rd in Piedmont, South Carolina, is a U.S. manufacturer of industrial safety equipment organized into four core product franchises: ventilation blowers (axial, centrifugal, venturi, air-driven, and jet fans in sizes from 8" to 26"), respiratory protection (NIOSH-approved supplied-air respirators, breathing air blowers, cold air sources, hoods, masks, and fit-testing kits), confined-space products (manhole guard rails, lid lifters, the patented Manhole Ventilation Passthru (MVP), shelters, and tents), and ducting/accessories (including standard, statically conductive EX-grade, and lay-flat options). Secondary lines span welding fume extraction and PAPR/SAR systems, high-output industrial fans, ergonomics supports, knee protection, lens care, seasonal climate control (cooling/heating vests), and air-sampling cassettes and pumps. The technical backbone is electro-mechanical — explosion-proof electric and Honda gas-powered motors, NEMA-rated plugs, UL Listed/CSA-certified housings in LLDPE and ABS, and ATEX-certified air-driven motors for hazardous locations — rather than software or AI-driven. Allegro operates exclusively through an authorized-distributor channel in the United States, Canada, and international markets, supported by a field sales rep network, an electronic literature library, a proprietary CFM Blower Selector decision tool, training videos, and mobile apps for iOS and Android.

Product overview

Allegro Industries is a safety equipment manufacturer established in 1987, acquired by Walter Surface Technologies in January 2022. The company offers a comprehensive portfolio of industrial safety equipment organized into multiple product lines: Ventilation Blowers (Axial, Centrifugal, Venturi, Air-Driven, and Jet Fans in various sizes from 8" to 26"), Respiratory Protection (masks, hoods, breathing air blowers, breathing cold air sources, fit testing kits), Confined Space Products (manhole guards, lid lifters, shelters, umbrellas, tents), Ducting and Accessories (in multiple diameters with standard and statically conductive options), Welding Equipment, Fans, Ergonomics Products, and Seasonal Climate Control items. The products work together as a safety ecosystem where blowers connect to ducting for confined space ventilation, respiratory systems provide breathing air, and confined space products ensure safe entry and work conditions. The company also provides a digital CFM Blower Selector tool for product selection.
