Johnstown's global CBD oil extraction manufacturer nearly doubled the size of its facility as states have lined up to legalize marijuana for medical and recreational use.

Apeks Supercritical, the Johnstown-based manufacturer of botanical extraction equipment for the marijuana and CBD industries, has moved into its new 30,000-square-foot home. Inside the facility, 44 employees manufacture, configure, crate, sell and ship the machine founder and CEO Andy Joseph began making 18 years ago in a pole barn in his backyard.

In the attached slideshow, check out the facility where Apeks employees make cannabis oil extractors by hand.

Over the past seven years, Apeks Supercritical has increased its revenue by 3,000 percent as states have legalized medical and recreational use of marijuana. The company recently celebrated delivery of its 600th machine, as CBD and other hemp- and cannabis-infused products continue to rise in demand nationally. Its former 17,000-square-foot space, which is adjacent to the new one, soon will house a cultivation facility. Joseph also is in the process of opening a cannabis dispensary in Newark.

Apeks says it was the first to design carbon dioxide extraction systems specifically for cannabis oil extraction. The company is owned and operated by U.S. Navy veteran Andy Joseph and his wife Kristen, who are certified welders and engineers.
