Kraemer MFG fans use either fabricated steel or 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 nonmagnetic and non-toxic, Kraemer MFGs pressure blowers are recommended for both electronic and food related applications. The non-sparking properties qualify Kraemer MFGs pressure blowers for AMCA Type B spark resistant rating. Standard steel housings are also widely acceptable in the wood and plastic industry, providing a cost effective and powerful solution to air & particle movement.
