The weight of phenolic composite air duct is light, about 1.4 kg/m2, while the bulk density of galvanized steel duct (0.8mm thick) and glass fiber reinforced plastic duct (3 mm thick) are 7.08 kg/m2 and 15~20 kg/m2

The Ventilation System (fresh air system) is an independent air treatment system composed of a supply air system and an exhaust air system. It is divided into two types: a ducting fresh air system and a ductless fresh air system.

The unidirectional flow system is a diversified ventilation system formed by the combination of central mechanical exhaust and natural air intake based on the three principles of mechanical ventilation system.

Summer is the peak season for air-conditioning. However, some careful users will find that there are some small water droplets on the air-conditioning outlet panel, thinking that the air conditioner indoor unit is leaking. In fact, these small water droplets are air-conditioning condensate water.

Everyone knows that air-conditioning shutters are used in fresh air systems and central air-conditioning systems. According to the material, the air outlets are divided into aluminum alloy air outlets,

From September 12 to September 15, 2021, our company participated in the Dubai BIG 5 exhibition, booth number 3F141. At the booth, we displayed our self-produced and sold machines for HVAC parts and ducts production through TV and posters.

The pre-insulated duct board（PIR, Phenolic）is produced by mechanization machine, the surface is smooth and flat, which improves the efficiency of air conveying, and the air leakage rate is only 10% of that of the iron sheet air duct.

The double louver tuyere is generally used as a tuyere, and it can also be used directly with the fan coil. It is widely used at the end of central air-conditioning system. It can also be used in conjunction with a split multi-leaf control valve to adjust the air volume.

Nowadays cutting machines are widely used in HVAC, engineering and construction industry. What do you know about them? That they cut things like paper? That you can cut everything with one machine and one knife? Let me show you some knowledge of cutting machine.
