11. The Ring Blow will be continuously at within the operation range shown on the wind flow rate to
static pressure curve (shown in the catalog). This operation range is so wide that the machine can
be operated at nearly closed pressure but, if you operate it at high pressure, especially take care
not to exceed the operation range. If you must operate it at closed condition, arrange a bypass
hole on the way, so that a more wind than required range flows through the blower even if the
suction port is closes (Figure 4).

12. For using air intermittently, the switching by means of a valve is recommended rather than the
switching on and off of the motor (Figure 5). The standard for start and stop frequency of Ring
Blow shall be not higher than the values in table below.
