FT Curtis Air compressors are energy efficient and yer reliable compressors. The FS Curtis brand may represent the new normal in the industrial equipment manufacturing field. 

They offer a large range of air compressors from medium-duty to large scale industrial air compressors. In this buyer’s guide, we will review where are those compressors made, the product line, pros and cons, parts, service, and much more.




Where Are FS Curtis Compressors Made

One of the significant issues in today’s market is the question of the origin of the equipment sold by any manufacturer or distributor. 

“Made in the USA” labels are often a considerable part of the decision on which piece of equipment to purchase. This is a reasonable question considering the sometimes questionable manufacturing and quality control coming out of some offshore facilities.

In 2005 Curtis -Toledo, as it was then known, was purchased by the Fusheng Industrial company from Taiwan. The company name was changed to FS Curtis to reflect this ownership.

Almost immediately, some of the manufacturing in the US was moved offshore to Taiwan. We should note that most of the larger parts of the FS Curtis line of compressors are still manufactured in the US and then assembled with some imported parts.

The question remains whether this constitutes “Made in the USA” or should these products be advertised as “Assembled in the USA?

Parts & Quality Control 

In the end, FS Curtis may represent the new normal in the industrial equipment manufacturing field. 

Many industries are seeing the purchase of a long time USA based companies by foreign investors and becoming a part of a multi-national conglomerate. Economics is the driving force behind these types of consolidations.

How this plays out for the consumers is questionable. Product quality control that was once easy to manage when parts were made and assembled in one plant is now much more difficult.
