We will appreciate it a lot if you can offer us your product performance requirement and operation environment for the Centrifugal Fan of you need, so that we can customize optimal product to meet your every requirement.
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.
1. What is airflow?
Airflow 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).
2. What is static pressure ?
Static 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
3. What are air performance curves?
Air 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).
4. What is The resistance of Pipeline Systems ?
The 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.
5. What is motor insulation?
Motor 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.
6.What is the minimum recommended starting voltage for AC blower motors?
In 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
7. Can a pneumatic actuator be used to centrifugal blowers?
Yes, 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.
