(1)WS9290B-24-220-X300blower is with brushless motors and NMB ball bearings inside which indicates very long life time; MTTF of this blower can reach more than 20,000hours at 20degree C environmental temperature.

(2)This blower needs no maintence;

(3)This blower drived by a brushless motor controller have many different control functions such as speed regulation,speed pulse output,fast acceleration, brake etc.it can be controlled by intelligent machine and equipment easily.

(4)Drived by brushless motor driver the blower will have over current, under/over voltage,stall protections.

This blower can be widely used onto air pollution detector,air bed,air cushion machine and ventilators.

This blower can run at CCW direction only.Reverse the impeller running direction can not change the air direction.

Filter onto the inlet to protect the blower from dust and water.

Keep the environmental temperature as low as possible to make the blower life time longer.

The flow rate (typically: liters per minute), at which a blower supplies air or another respiratory gas to the system, depends on the resistance to the flow (also referred to as "static pressure" or "system pressure") that the blower has to overcome.A specific value of the flow rate corresponds to a specific value of the resistance for a specific fan speed (revolutions per minute). A particular type of blower is characterized by a set of curves in a Cartesian space spanned by a first axis, each particular point whereof corresponds to a particular value of the flow rate, and a second axis, of which each particular point corresponds to a particular value of the resistance . Each specific one of the curves corresponds to a specific value of the fan speed. For, e.g., a radial blower, the curves are largely uniform, and offset with regard to one another in the direction of the second axis. For additional technical information see, e.g., "Fan Fundamentals: Fan Selection, Application-Based Selection, Performance Theory", Rev 2, June 2005, Greenheck Fan Corp.

The blower is not an ideal pressure source, because the flow rate decreases with increasing system pressure (or: resistance to the flow). As a result, the flow rate is sensitive to fluctuations in the system pressure. Fig.1 is a diagram 100 of a typical fan curve 102 illustrating this sensitivity. Curve 100 represents the dependence of the flow rate (horizontally, in liters per minute) on the system pressure (vertically, in mbar) at a particular fan speed. In principle, the blower can be used to control the flow rate, but the flow rate varies with varying system pressures. For example, if the system pressure varies between 55 mbar and 60 mbar, the flow rate fluctuates between 5 l/sec and 40 l/sec in the example illustrated.
