Direct Drive Air Compressors

Description

Direct drive compressors are more efficient because less power is lost in transmission from the motor to the crankshaft. While direct-drive models generally cost more to buy outright, the initial investment pays off over time as they require less fuel over the life of the unit.
Compared with belt-driven compressors, direct-drive air compressors have fewer moving parts, so they do not require parts to be replaced due to wear and tear. Therefore, they can withstand continuous use in industrial environments.
If you work in harsh conditions or extreme temperatures, the direct drive model is your choice. This type of compressor is designed to withstand temperatures below freezing and up to 40°C. Synthetic oil is recommended for use in summer and winter as it does not change properties in extreme temperatures.
