Direct driven or belt driven
The direct-drive compressor, or "Direct Coaxial Drive" is what gjortFini known across virtually the entire world. Electric motor and compressor block parts suspension and the benefits for smaller machines are many, some nämnvärdaär better efficiency, "simpler" design - fewer errors plus atthela compressor becomes an enclosed unit with no moving parts utvändigtutöver fan.
The belt-driven compressor lacks its own drive and connected to elmotornmed belt drive. These blocks have the advantage of being able to be switched to different speeds ochsåledes different maximum pressure within certain limits. Are generally more common on the larger machines and consistently maintains a high quality with such cast iron cylinders, controlled air flow and acoustic inlet filter. BK modellernaär two-step and all have a cast aluminum heat sink between steps attytterligare raise efficiency.
