Q1: What`s CFM?

A: CFM is the acronym for Cubic Feet per Minute - the measure of air volume moved by the fan blower. Choose a fan with a CFM rating appropriate for your room size to ensure adequate ventilation.

Q2: Can supplier offer more options of the material for the outer frame or the inner blades?

A: We will show the usual quality we produce for bulk. If buyer has other requirements, we will try our best to reach. But it all depends on the real use.

Q3: Will you offer samples of your products before bulk?

A: Yes, we will send one sample to buyer based on your request for check and confirmation.

Q4: How much are all the shipping costs?

A: It depends on the weight and the volume of the bulk packages and the final destination.

Q5: Will you accept rush order?

A: We will check our schedule of the bulk production as well as the stock. If everything is ok, we will help buyer to speed up the bulk.

Q6: How do I choose a proper ventilation fan for my bathroom?

A: For bathrooms less than 100 square feet, determine the room’s CFM requirements by measuring and multiplying the length, width and ceiling height of the room, then use the multiplication factor of .13 and round up to the next “ten.” For example: 10’ long x 8’ wide x 9’ height x .13 = 93.6, select a bath fan with at least 100 CFM. If the bathroom is larger than 100 square feet, recommends that you add the CFM requirement for each fixture present - a toilet is 50 CFM, a shower is 50 CFM, a bathtub is 50 CFM and a jetted tub is 100 CFM.

Q7: Can inline centrifugal fans be used for continuous high temperature exhaust applications?

A: Inline centrifugal fans (GFC models TCB or TCF) are not recommended for use in high temperature continuous exhaust applications. The reason is based solely on inline centrifugal fan design, which has the impeller at the inlet of the housing. As seen on the following diagram, the fan housing becomes pressurized and heated to the temperature of the incoming air. Leakage of heated air and heat transfer through the bearing cover and belt tube reduce the life of the bearings and motor. Our recommendation is not to exceed 200℃ with inline centrifugal fans.

Postscript

We only have one earth and we humans all have responsibility to make contributions to protect it. As the global warming is getting worse, it`s urgent for all of us to get together to think about doing something as we can to solve or maybe slow down the speed of air pollution. Lei`s hold hand in hand and create a brighter and hopeful future.

Thank you very much!
