Direct Driven Air Compressors have several advantages over their belt-driven counterparts. These air compressors are less expensive and require a replacement pulley only. Their no-load pressure difference is approximately two bars, so it is not possible to achieve zero pressure when running on no-load.
Direct Driven Air Compressors are generally quieter than belt-driven counterparts. They are best for use in low-noise environments. However, they are not ideal for use in industrial environments, where vibration and noise are important. Hence, it is important to consider the environment in which the air compressor will be placed before choosing one.
Direct Driven Air Compressors are also more efficient. They require less maintenance, which is critical for industrial use. These air compressors are available in different horsepower ranges. Their capacity ranges from 25 hp to 700 hp. In addition, their one-to-one drive eliminates transmission losses. They also feature synchronous reluctance motors, which are more energy efficient than their gear-driven counterparts.
Direct Driven Air Compressors have fewer moving parts and are quieter than belt-driven counterparts. Belt-driven air compressors have more power and require less maintenance, but they tend to be larger and heavier. Therefore, they are better suited for heavier duty applications.
