1. Different application conditions, smoke boxes can be used in fire -fighting systems of various types of buildings, and the exhaust box can only be used for construction machinery ventilation.2. The product selection of the product is different. Because the smoke exhaust box needs to be applied to the fire fire exhaust system, it needs to have high temperature resistance. Therefore, the cigarette box box generally uses a good hot -dip galvanized steel plate.The noise has very strict requirements. Therefore, the exhaust shell is generally used in good aluminum profiles. The panel materials are generally Δ30mm thick color steel plates (produced by Baosteel).The heating material of polystyeyrene has greatly improved the insulation performance of the unit shell, which can ensure that the unit has no cold bridge as a whole. The inside of the sound -absorbing cotton can play a role in sound and noise and noise.3. Different structures. Due to the conditions of the use of the use of the working conditions, the box is resistant to high temperature. Therefore, the motor of the box is external. It is transmitted with a belt to facilitate heat dissipation and protect the motor to delay the service life of the motor.The exhaust box structure is generally built -in motor. On the one hand, the exhaust system does not require high temperature resistance. Secondly, the motor can reduce the area of ??the box, flexible installation, and can also be used for the small installation environment.4. Different prices. For the requirements of motor, plates, etc. are different from the exhaust box, the overall cost smoke exhaust boxes are higher, but the two play a different role in their respective systems. Therefore, even if the price is lower, smoke discharge smoke, and smoke discharge.The system cannot use the exhaust at will
