Overload Protection & Reversible Operation Equipped with anti-spray and resistance composite muffler: The motor noise during operation is as low as 40-60dB, reducing the noise in the working environment Bearing baffle plate: Made of PP material, it prevents corrosive material liquids from splashing onto the bearing The motor output shaft adopts die forging process: 42Grmo material is used. The forged part can effectively enhance the impact resistance of the motor output shaft and undergoes modulation and surface quenching heat treatment process to strengthen the toughness and surface wear resistance of the output shaft Equipped with a full copper fine-tuning valve: When regulating the air flow, no sparks or static electricity are generated due to friction, ensuring safety and explosion-proof The motor housing is integrically die-cast: it features high strength and can withstand large pressure. The surface of the housing is nickel-plated, which ensures no corrosion or peeling when exposed to solvents and chemicals. It meets the high-demand working environments in food, cosmetics, dust-free electronic rooms, and pharmaceutical and chemical industries, Manufacturer: MERHOVO
