Ventilation pipe construction Detailed specifications for equipment installation
Today, it is completed in architecture Ventilation engineering All facilities for construction work, collectively referred to as Ventilation duct Equipment. The ventilation duct equipment is divided into exhaust fan, ventilator, fan, etc., and also divided into industrial and household. The fan is divided into high, medium, low and negative pressure.
Detailed specification for installation of ventilation duct equipment
Ventilation engineering construction
