3B Filters, Inc. was established in January 2001.
Its parent is Demco Products, Inc. which was founded in 1950. Demco Products is family owned and
operated and has a combined total of over 80 years experience in production and precision machining.
With a 15,000 sq. ft. facility and more than 20 CNC machines, Demco has a history of performing
engineering, design work, and manufacturing for customers in the areas of scuba diving equipment, medical
oxygen supply, emergency breathing equipment and pneumatic cylinder equipment to name a few.
Beginning in 1978, Demco Products manufactured and sold a line of high pressure filter housings to other filter
companies. This product line consisted of mini in-lines, in-lines and large T-types made from aluminum and
stainless steel as well as a wide array of exotic metals. This product line was sold to the aerospace, petroleum
and chemical processing industries as well as many others.
In the late 1990’s, Demco made the decision to manufacture, sell & distribute its own line of high pressure
filter housings under the 3B name.
