Q:What kind of duct valves are required in the exhaust duct and near the fan?

Through the test, the air volume regulator valve air tightness is good, the relative leakage of about 5%, good regulation

Q:What is the principle of explosion-proof fan?

FT35-11 and BT35-11 fan performance parameters and dimensions are the same as the T35-11 fan. The fan requires a foot and motor voltage. Please specify when ordering.

Q:What is the reason for the vibration of the fan?

Impeller itself irrational structure, such as the number of even into the number of leaves,

Q:What is the difference between an axial fan and a centrifugal fan?

The former often installed in the air conditioning unit into, exit, boiler drum, induced draft fan, and so on. The latter is often installed in the duct, or the duct outlet front.

Q:Is the centrifugal fan plugging the air inlet motor?

However, the motor is still running at high speed, the corresponding mechanical loss and other losses, but still continue to consume, and block the air intake of this way to save the electricity is much greater.

Q:How to see the axial fan is good or bad?

1, to determine whether the normal axial fan, just test the motor's three-phase DC resistance, insulation resistance, check the impeller rotation is flexible, whether there is too large radial string and axial string,

Q:How to install the axial fan?

1, to see where you want to install, the ground is still underground, the room whether there are windows, etc., because of its consideration to the number of ventilation (in addition to the kitchen, bathroom and other places, the general number of ventilation to take 10 times per hour;

Q:What is the difference between centrifugal fans and centrifugal fans?

AC ion fan is mainly by a group of discharge electrode positive and negative ions, the first emission of positive ions to re-launch negative ions or the first emission of negative ions and then re-emission of positive ions, are completed by a group of discharge electrodes, there is a time difference.

Q:What is the operation of centrifugal fans and axial fans?

In a single stage centrifugal fan, the gas enters the impeller from the axial direction, and the gas flows into the radial direction through the impeller and then enters the diffuser. In the diffuser, the gas changes the flow direction to cause deceleration, which slows the kinetic energy into pressure energy

Q:380V axial fan has five lines how to take?

At the same time, the best way to measure the wiring before the axial flow of three lead-out line between the two DC resistance to see if the same. If the same, that is really three-phase 380V power supply,
