Central Vacuum Power Units

The power unit of a central vacuum is the main vacuum that powers the suction throughout the house. Usually, you would place them in the garage or basement, though a large closet or attic would work but only as a last resort. We have many different units to choose from depending on the size of your house. The most important factor to measure the efficiency of a central vacuum power unit is CFM (Cubic Feet per Minute), which is essentially the speed the air will be moving through the pipes. This measurement is actually quite different then suction power, and will be what keeps your system from clogging in the years to come.

Modern Day Silent Master S2
Price:$Call For Quote - 1 800 479 VACS (8227)
A twin motor central vacuum system with excellent CFM. Designed for homes up to 6000 square feet. Will deliver premium performance for many years. It uses a 12 gallon capacity paper bag which is inserted into a cloth bag along with three additional filters, all to protect the motors and the exhaust. The average person will use 1 to 2 bags per year. We prefer paper bags over bagless because you don't have to empty as often, and it's generally an easier and cleaner emptying system.

Modern Day Silent Master S4
Price:$Call For Quote - 1 800 479 VACS (8227)
The Silent Master S4 is a single motor central vacuum unit designed for homes up to 6000 square feet. This model is used and recommended primarily for people who have decided not to use super valves, and want to use a lighter weight air driven nozzle. You will find that air driven nozzles are easy and effective, but not as effective as the electric power nozzles powernozzles. Okay for those consumers with a smaller amount of rugs and no pet problems.

Modern Day Silent Master S5
Price:$Call For Quote - 1 800 479 VACS (8227)
is the grand daddy of them all. It houses 2 large motors. Designed for homes up to 25,000 square feet. We have installed S5 units in homes with 20 or more inlets and have never experienced poor performance anywhere. This central vacuum system is overkill in the average size home. But the cost differential from an S2 to an S5 is not that large compared to the difference in performance. The one drawback to the S5 is that it will consume 28 amps of power, and would need heavy duty wiring in a 30 amp line. So in a smaller house it might be a bit costly to operate.
