Key Materials & Info

The existing domestic stainless steel ventilators have no difference between good and bad quality, since stainless steel ventilation adopts stainless steel of different material quality. Under normal circumstances, anticorrosion of higher-quality 304/ 2B stainless steel has been uncommon compared with stainless steel of other materials. However, confronted with some badly corrosive and terrible air atmosphere, such as shore workshop, acid washing workshop and so on, it far exceeds its ability. If adopting higher-quality stainless steel with nickel as raw materials of ventilator, its price is too high for most customers. But current common aluminum alloy ventilator has short service life due to the neglecting of anti-corrosion and anti- oxygen.

Metal tech has been leading in the improvement of performance and service life of ventilators. The newly researched TR fluorine carbon polyester coating aluminum alloy ventilators remedy some shortcomings of common stainless steel and aluminum alloy coating ventilators, providing the possibility of ventilator’ s being applied in special trade and circumstance.

Ventilator Exhaust Calculation and Determination

1 Determine the indoor volume of the building in cubic meters (length×width×height) = VOL
2 According to the building type, determine air changes per hour required from the table 1 =N  
3 Determine the standard wind speed according to local weather records (1.2.3.4and 5m/s), thus air exhaust capacity can be reached from table 2 = L p

The number calculation formula of ventilator:
