Design 38 Cast Aluminum Pressure Blower

Chicago castings blend aluminum with high-strength alloys to create strong, corrosion-free housings and wheels ideal for adverse industrial environments. Aluminum also stands up to sub-zero ambients without material deterioration. Since aluminum is non-magnetic and non-toxic, Chicago's pressure blowers are recommended for both electronic and food related applications. The non-sparking properties qualify Chicago's pressure blowers for AMCA Type B spark resistant rating.
