Yes, it's not how to reduce roots blower noise level, it's how to reduce turbo blower noise level.
Normally turbo blower noise level is less than 80 dba when roots blower noise level is more than 90 dba, some user are still not satisfied, they want the noise level below 60 dba or even 50 dba.
Turbo blower ZCJSD has it's own suggestion to reduct turbo blower noise level: Wrap the outlet pipe with sound-absorbent material， please see below photo:
What else can I help you with?
The AC works only on the highest settin and when it blows its making a noise what could be the problem?
As for why it blows only on the high speed you most likely will have a bad blower resister and for the noise, it could be a bad blower motor, bad blower wheel or trash that is stuck in the blower wheel or housing.......
What does the blower motor resistor do?
It controls the amount of current the blower receives so that is operates at the speed level you select ie: Low, Med, High.
How do you increase speed on a Lennox blower motor The tech put it on lower speed last summer until we replaced the squirrel cage We did and how do we increase the speed now?
Reduce the size of the pulley on the motor
What functionality is lost if the power connector from the CPU fan has only three pins?
PWM (pulse width modulation, which controls fan speed in order to reduce the overall noise in a system.
On the 2002 Nissan Maxima when the blower resistor is bad does it make a vibrating noise?
A bad blower resistor will not make a vibrating noise by itself. Carefully remove the blower resistor (under the dash at the passenger side right foot area.) check to see that it is not hitting the fan. PS a bad blower resistor usually means that the blower will only operate at high speed. Usually a small fusible link on the resistor ceramic opens. Can be replaced with a small link of unmelted solder.
What is the purpose for the relay fuse for the blower in the 1993 Cadillac deville?
The blower motor fuse protects the blower motor electrical circuit. The blower motor relay operates only the high speed function of the blower motor. The blower motor speed resistor operates the lower speed functions of the blower motor.
Your heater blower will just work on high speed?
The blower motor speed resistor is burned out. The high speed function bypasses the resistor. The speed resistor is generally located near to the blower motor.
El Camino blower high speed fuse location?
if your blower is working on low and medium speed then it's not a fuse it is the blower switch
How can I change the blower speed on my furnace?
To change the blower speed on your furnace, locate the blower motor and adjust the speed settings on the control panel. This can usually be done by turning a dial or pressing buttons to increase or decrease the speed. Refer to the furnace manual for specific instructions on how to adjust the blower speed safely.
How can you get power to the blower motor in a 1995 Mazda b4000?
Check the fuse. Check the blower speed resistor. Check the blower speed control switch.
Blower on 2001 Buick wont recirculate and increase speed only makes noise?
2001 buick lesabr // when recirculate speed doesnt change only make humming sound rest of heater works fine
Why is your car making a grinding noise when you have the AC or heat on and you brake to slow the car and or give it gas?
It is probably a worn blower motor, because it happens with AC, and/or HEAT. When you brake or speed up, you are changing the speed of the motor (adding and taking away resistance to it's spinning). This will cause more of a noise until you reach your cruising speed again.
