The Cyclonic Filtration Technology (CFT) Difference

Central vacuum systems need the proper proportions of maximum air movement and effective filtration to guarantee high performance cleaning. Bags and filters can clog quickly and reduce airflow and vacuum power.

The filtration method of Cyclonic Separation delivers the highest sustained cleaning performance because the dirt is removed from the airflow without restriction. Cyclonic Separation, as defined by the Dictionary of Physics, requires three criteria to be met: high-speed rotating airflow, a conical container, and downward motion. Only Cyclonic Filtration Technology® (CFT) from H-P Products meets all three criteria.

CFT is an exclusive dual filtration process designed to deliver maximum cleaning power every time you vacuum. CFT begins with Cyclonic Separation to remove dirt, dust and allergens from the incoming air stream without bags or filters. Cyclonic Separation starts the moment vacuumed dirt enters the power unit from the intake. As the dirt-laden air begins a downward descent, it spirals along the inside of the unit, picking up speed and forcing 96-98% of the vacuumed dirt into the dirt canister. The remaining fine dust particles are pulled upward with the airflow and are trapped in a high-efficiency pleated filter cartridge. Less than 5% of the vacuumed dirt is exposed to the filter and only clean air is left to exit the power unit exhaust.

Versus Permanent Cloth Filter System

• Cleaning performance decreases quickly as the permanent cloth filter becomes clogged with dirt.
• Airflow forces 100% of all vacuumed dirt directly against the permanent cloth filter – no cyclonic air path or separation is achieved. The result is dirtier filters for greater clogging potential and less vacuum power.
• Debris is not released from the permanent cloth filter until the vacuum system is turned off. This helps to unclog the filter, but a dirt film remains – reducing original performance.
• Permanent cloth filter systems can not be restored to like new condition once dirt and dust are embedded in the filter. Coatings like GORE-TEX® and Teflon® help reduce embedded dirt, but do not eliminate it.

TERMS AND DEFINITIONS

There are many measurements manufacturers might use to assess their vacuum system’s performance. But, what does it really mean?

Amps represents the amount of electrical current consumed by the motor during use. The implication is that the more electricity the motor uses, the more powerful it is. This is not necessarily true. A motor that uses more electrical current does not always mean the current is being used more efficiently.

Horsepower measures the power of a motor. Horsepower can vary according to voltages, motor loads and temperature variances, and is not an accurate measure of how well a vacuum system will pick up dirt.

Sealed Suction measures the maximum suction generated by the motor without airflow. Because vacuum cleaners rely on airflow to clean effectively, high sealed suction without airflow will not clean anything.

CFM is the maximum volume of airflow measured in Cubic Feet Per Minute. Maximum CFM ratings occur when the vacuum system is operating without restrictions to airflow. In normal vacuuming conditions, hoses, cleaning attachments, bags, filters and accumulated dust create restrictions to airflow, reducing CFM. Therefore, CFM alone is not a good indicator of vacuum cleaning performance.

Maximum Air Watts represent the air power delivered by the power unit. CFM and Sealed Suction are combined to represent actual vacuum cleaning power. Maximum Air Watts is recognized by the American Society of Testing and Materials (ASTM) as the best way to measure the actual cleaning power of a vacuum system.

Sustained Cleaning Power is the ability to maintain Maximum Cleaning Power over time. Cyclonic Separation, used in all systems from H-P Products, delivers the highest sustained cleaning performance because the dirt is removed from the airflow without restriction.
