WEG Variable Speed Drives

The CFW-08 NEMA4x variable speed drive from WEG has many of the great features and benefits of the original CFW-08 but now has an IP66 rated enclosure. This protects against the threat of dust, high-pressure water and corrosion. Its rugged water protection design allows it to be utilized in harsh environments like wash down applications without the need for custom enclosures. In addition to the already great design, the totally painted heat sink adds an additional level of protection, which results in less maintenance and a longer lasting appearance.

All electrical boards are conformal-coated offering protection against dusty, humid environments. The WEG CFW-08 vfd’s are found in wide variety of applications including the Petrochemical, beverage, food and chemical industry.
