Our Mission
NVE is dedicated to the manufacture and wholesale distribution of quality
vacuum system products at a reasonable price and delivered on a timely
basis. NVE is a “one-stop shop” for manufacturers and distributors of
vacuum equipment.
Our History
National Vacuum Equipment, Inc. was founded in 1980 by Bruce Luoma.
NVE started as a retailer of vacuum pumps. Soon after it started, NVE
secured the rights to exclusive distribution of the Battioni vacuum pumps
in North America. This allowed NVE to evolve into its current status as a
wholesale supplier.
To reach the goal of becoming a full service supplier of vacuum system
components, NVE began fabrication its own line of componentry,
purchased and developed its own line of vacuum pumps, and began
purchasing for resale various valves and accessories.
Today, NVE has full service machine, fabrication and powder-coating
shops complete with CNC-controlled production equipment designed for
close tolerance work. Our staff is highly trained and are committed to
quality from start to nish.

or are impossible or impractical to test prior to the installation
of the item in a vacuum system. It is therefore the responsibil-

and components supplied to the assembler by NVE prior to the
delivery of the nal product to the end user.
Any items found to be defective after delivery to the end user
that should have been discovered prior to deliver will qualify
replacement of the defective part only with absolutely no com-
pensation for outside labor or travel expenses. Any subsequent
damage to other components caused by the defective part will
be the sole responsibility of the assembler.
