This is to prevent such things as carpet fiber, cloth, etc. A buildup of dirt or other larger, clogging- type material may result in loss of vacuum. Therefore, you have constant airflow and no loss of cleaning ability. Let the buyer beware, this confusion has lead to owners of these systems being dissatisfied with their system's power and the motor's life. Vacuflo claims that their system will . The remaining 2% consist of small particles which are exhausted outside. But - consider this: $1. The cyclonic action does eliminate a high degree of the debris; however, fine dust and lint need to be kept from the motor for thorough protection. Inspect and brush off filter. When this happens, the vibration in the motor increases. The high- speed operation of the motor makes balance critical and as vibration increases, premature motor failures can result. This is one reason we are so concerned about adequate filtration. The amount and rate of dirt build- up on the fans in an inefficient design or unmaintained system can cause problems sooner than a customer expects. When this happens, we all have a problem. The main reason for this is that they expect their systems to only last five or six years. Filtered Systems.

We at MD will be the first to admit that our bag filtering system will affect performance as the paper bag fills up but we qualify that statement with the fact that properly maintained bag filtration systems are the best for the performance and life of your system. Semi- annual replacement of a paper bag makes a lot more sense than the loss of performance and motor replacement costs on cyclonic systems. A cyclonic separator is first installed to remove the large debris and then a separate paper bag filtration unit catches the fine particles. This will certainly minimize motor failure. Obviously, however, the finer the filter, the quicker the loss of performance. Central vacuum tubing from the wall inlets terminate at air and debris intake(s).

The filter bag is supported by a porous heavy- duty cloth secondary filter. Notice the taper of the bags, which allows maximum surface area for maximized airflow. The air in this open area around the bag and near the motors is tremendously cleaner than cyclonic models, thus protecting the fan blades from build up which causes early failure. The last stage of the secondary filtering is made of breathable mesh. High performance motors in the motor compartment are kept clean by the filtration system above it. While cyclonic models normally need to be vented outside, this filtration system keeps the exhaust much cleaner without any need for venting outside. And any filter you install (screen, cloth, foam, paper, etc.) will impede airflow in some manner. What makes one system better than another is its ability to minimize debris around the motor while maximizing airflow for vacuum power.
