swapping in this replacement blower motor restores factory-spec CFM and keeps the system running within its designed temperature rise

Precision Fit: Designed specifically for 1-inch screw-in elements to ensure a compression seal that prevents water-side bypass and external leakage

reducing the need for universal stock that requires modification

though high-wattage kits like this 25kW model require specific blower speed tap adjustments to maintain proper temperature rise
