- Impellers with 20~64 blades, forward curved with narrow width used for air- conditioning purpose
- Fan drive system divided into motor direct drive and V-belt drive
- Both single/ double inlet possible
- From the inlet viewpoint, rotation decided upon direction of clockwise or counter-clockwise
Technical Data
| Conventional Type - High air volume, High static pressure - High speed R.P.M - The material of impeller is aluminum(AL), Steel(GI) | Molding Type - Low air volume Low static pressure - Low speed R.P.M Low noise sound - The wheel width is various and the material of impeller is aluminum(AL),Steel(GI) | Rolling Type - High air volume Low static pressure - The wheel width can be adjustable and efficiency is high - The material of impeller is aluminum(AL),Steel(GI) |
- Suitable for intake and exhaust for high-static pressure with low air flow
