N&h series exhaust fan is an advantage product of our company, which has the characteristics of large air volume, long life and low price.
N&h series exhaust fan is a high quality exhaust fan.
275g galvanized coated galvanized sheet is selected as raw material, which has stronger corrosion resistance.
The fan blade has a large angle, which resulting in a particularly large air volume. The fan blades adopt single punch forming from imported stainless steel plates to ensure strength and durability.Because of the larger air volume, we recommend to use of Chinese high-end motor or Siemens motor , which is the basis for ensuring normal operation.
We must use high quality motors to ensure its normal operation.
Every fan has been tested by dynamic balance, which ensures its best effect and maintains balance.
The triangle belt adopts Japanese Mitsubishi brand to ensure the effect and life.
The column adopts international standard hot-dip galvanized square pipe.
The protective net is hot-dip galvanized steel wire, which has a long life and is strong.
Bearings we use single-disk double-row bearings, which are durable and run smoothly.
As the best-selling product, exhaust fan is widely used in ventilation and cooling. It is very popular everywhere, including outdoor, indoor, breeding grounds, parks, factories, agriculture, environmental protection and other industries.
