On a regular basis, we publish this catalog, with updated products and prices. A complete copy is available on our website for reference or download a catalog here. In 1997, we also provided a World Wide Web site to provide access to information about our products and services. We have information about products and prices, rebuilding services, special offers, news items, reports, Material Safety Data Sheets, quotation forms and product manuals. Check our home page frequently to keep up on our product offers. Our customer representatives can be reached by telephone, FAX and e-mail to answer your questions and take your orders.

Product Range

We have a large stock of new vacuum products and supplies, and in most cases, items are shipped the same day as ordered. Our wide access to used vacuum equipment and rebuilding services provides an additional excellent resource for low-cost solutions.


Our customers are worldwide. Universities, government laboratories, OEM's, Fortune 500 corporations and smaller end-users are all extensively represented in our customer base.


Duniway Stockroom Corporation also provides a selection of rebuilding services intended to extend the service life of your equipment and save you money. Unless noted otherwise, all of our rebuilding services come with our one year warranty covering defective parts and workmanship. Please check the specific product areas for services performed and the associated pricing.
