90% products of SIMO BLOWER are designed according to customers' performance requirements, each customer of SIMO BLOWER will use the most suitable product .But before purchasing, you should be attention to the following items that you must be aware.
 
XINXIANG SIMO BlOWER LIMITED COMPANY | SIMO BlOWER CMS1. What is airflow? 
XINXIANG SIMO BlOWER LIMITED COMPANY | SIMO BlOWER CMSAirflow is the volume of air moving through the blower fan or  pipeline. Calculation of measure are cubic feet per minute (CFM) or cubic meters per hour (M3/H).
 
XINXIANG SIMO BlOWER LIMITED COMPANY | SIMO BlOWER CMS2. What is static pressure ?
XINXIANG SIMO BlOWER LIMITED COMPANY | SIMO BlOWER CMSStatic pressure (Ps)is the gas's force that acting on the objects' surface that paralleling to the air flow, it can be measuredthrough the holes that Perpendicular to the surface. Kinetic pressure(Pd) is the pressure that create, when the gas is flowing.   Total pressure (Pt)is thealgebraic sumof kinetic pressure and static           pressure            Pt= Ps+Pd

XINXIANG SIMO BlOWER LIMITED COMPANY | SIMO BlOWER CMS3. What are air performance curves?
XINXIANG SIMO BlOWER LIMITED COMPANY | SIMO BlOWER CMSAir performance curves are graphs, which indicate the characteristics of air flow: airflow (cfm) versus static pressure (in. wc) and airflow (cfm) versus blower speed (rpm).
 
XINXIANG SIMO BlOWER LIMITED COMPANY | SIMO BlOWER CMS4. What is The resistance of  Pipeline Systems ?
XINXIANG SIMO BlOWER LIMITED COMPANY | SIMO BlOWER CMSThe resistance of  Pipeline Systems is the resistance to air flow when moving air through an airflow system. Examples: air filters, air grilles and abrupt changes in flow direction.
 
XINXIANG SIMO BlOWER LIMITED COMPANY | SIMO BlOWER CMS5. What is motor insulation?
XINXIANG SIMO BlOWER LIMITED COMPANY | SIMO BlOWER CMSMotor insulation systems are the materials used for wire and coil insulation and are classified according to the highest temperature at which normal service life can be expected. There are five motor temperature classifications: A (1050 C), E (1200 C), B (1300 C), F (1550 C) and H (1800 C). The maximum temperature rating is based on the temperature rise of the coil winding plus the ambient air temperature at the motor.
 
XINXIANG SIMO BlOWER LIMITED COMPANY | SIMO BlOWER CMS6.What is the minimum recommended starting voltage for AC blower motors?
XINXIANG SIMO BlOWER LIMITED COMPANY | SIMO BlOWER CMSIn general, seventy-five (75%) percent of the rated voltage of the blower motor is required to reliably start the motor. Example: Minimum starting voltage: 111 x .75 = 86V
 
XINXIANG SIMO BlOWER LIMITED COMPANY | SIMO BlOWER CMS7. Can a pneumatic actuator  be used to centrifugal blowers?
XINXIANG SIMO BlOWER LIMITED COMPANY | SIMO BlOWER CMSYes, the pneumatic actuator can be used to centrifugal blowers, actuator are designed the same, so check with our application engineers to insure trouble-free operation.
