Introduction BMAX is the new serie of motorized radial wheels of S&PTM This new range is coming from the long experience and high tech knowhow of S&P in fan technology. Using the most advanced tools available for aerodynamic investigation and the high its own knowhow in electric/electronic motors, S&P got the highest efficient and lowest noise fan range of the category. BMAX range had also a version with aTM revolutionary aerodynamic devide “LABI-SEAL” that used coupled with S&P inlet cone, designed specifically for these wheels, gives performances E208518 never seen before, increasing sensitively the efficiency and decreasing the noise at levels that others cannot achieve. BMAX range has wheels, one piece moulded, inTM high strength reinforced polyamide plastic material coupled with different external rotor motor arrangements to meet the largest requirements. BMAX wheel is lighter than the other solution,TM with large benefit in vibration reduction. 4
