(CFM) of Air Flow
"Peak Horsepower" (PHP) is a term used in the wet-dry vacuum industry for consumer comparison purposes. It does not denote the operational horsepower of a wet-dry vacuum but rather the horsepower output of a motor, including the motor's inertial contribution, achieved in laboratory testing. In actual use, Shop-Vac® motors do not operate at the peak horsepower shown.
Tank capacity refers to actual tank volume, and does not reflect capacity available during operation.
SP (Sealed Pressure)
Suction pressure represents how far up a glass tube a vacuum motor will lift
a column of water. This function is measured in inches. Maximum suction pressure
or sealed water lift is obtained at zero air flow. Suction pressure decreases
as air flow increases.
CFM (Cubic Feet Per Minute)
CFM is a measure of the quantity of air moved by the vacuum motor at a particular
system load, such as 2-1/2" orifice. Your actual system load is determined
by the type, size and length of the hose used, the accessory tool used and
the filter system used. A dirty filter system can drastically affect the
suction and air flow. The filters need to be cleaned regularly and replaced
as necessary to avoid reduced suction and air flow.
Vacuum performance or air power is the rate of work performed by a vacuum cleaner.
Air power is a function of suction and air flow at an operating point. Air
power is reduced by dirty filters, leaks and attachments used.
