All MD Manufacturing units are sold through local dealers eliminating all middle men, such as distribution companies. This supplies you with a great product at a tremendous value. MD Power units are not authorized to be sold or priced on any websites or under different product names or private labels.

* Factors other than air watts should be taken into consideration including: altitude, amount of hours of daily usage, complexity of pipe installation, length of furthest vacuum inlet, noise level desired, type and size of filtration, country of origin, construction materials, and budget. The square footage recommendations on this page are solely based upon the suction capabilities of the unit.

** SilentMaster Warranty
M.D. Manufacturing, Inc. warrants its SilentMaster power units against electrical component failure for a period of ten (10) years (for units produced after January 1, 2014). This warranty is transferable with the unit and is not solely limited to the original owner. Any parts (excluding filters) required within the first ten years will be furnished free of charge by the Authorized Dealer from whom the power unit was originally purchased. In addition, all SilentMaster units are guaranteed for life against defects in materials and workmanship. If an Authorized Dealer is not nearby, M.D. Manufacturing, Inc. will honor and perform required warranty services. The end user must return the unit to the factory freight pre-paid. This warranty does not apply to applications outside of North America, commercial applications, misuse, abuse, acts of God, operating without the filters, or units tampered with by unauthorized personnel.
