Specifically designed for applications where ultra-high waterlift is critical. The M850 has two all-metal Ametek motors in Air-series to create 224” waterlift, ideal for any hose-retraction system. With both motors located on the bottom of the tank, critical cooling air is drawn from the lowest room elevation possible. Also included is a technically engineered single-port exhaust with muffler and special connections.

ModernDay Warranty
M.D. Manufacturing, Inc. warrants its Modern Day power units against electrical component failure for a period of ten (10) years. 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 Modern Day 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.
Exterior Venting
Venting not required but optional on most Modern Day units.
* A central vacuum’s square foot coverage should be based on factors including altitude, hours of use, complexity of pipe installation, length of furthest vacuum inlet, noise level desired, type and size of filtration, installation materials, and budget. The square footage recommendation on this page can be higher or lower when taking these factors into consideration.
