DAISEN 'DS series',as an earlier generation of HVLS fans,have been selling well in the market for more than ten years. They are equipped with German brand gearbox brushless motors,with big torque and big air volume,and complete machine safety protection. All accessories meet industrail standards and are suitable for various harsh and industrial occasions.

* Standard universal mount compatible with most common industrial building structures
* Up to 240Nm of torque for easier and more stable high air volume output
* The fan blade handle is flexibly connected to release high-frequency vibration, and there is no metal fatigue for long-term operation
* Comply with CCC, CE, UL and other international standards, and key components have passed safety testing
* Industrial-grade safety product requirements, long-term stable operation in harsh and harsh environments
 

Features of Traditional HVLS Fans
 

Universal joint:
The galvanized structure steel universal joint,can adjusts the horizontal and vertical direction to ensure the fan in vertical status. So that ensuring the balance of the fan in the process of rotation, and reducing the torsion transmission from the fan to the building.

coupling:
40Cr alloy coupling, CNC machining to ensure transmission stability
Other product accessories:
Select high strength screws greater than 8.8 grade according to different connecting parts of the fan,anti-loosing self-locking screws and and anti-slip nuts,together with anti-loosing thread glue,anti-falling connection rings,anti-falling connection parts of the blade.

PMSM(EC) Motor:
Permanent magnet synchronous motor (PMSM) ,brushless and direct drive, no gearbox, no transmission lubricating oil, permanent maintenance free,220V / 0.7KW high efficiency, energy saving, quiet and efficient

Installation kits:
Our company's unique design of row holes on the installation plate, can prevent the sliding of the installation plate, we also have installation kits for concrete and and circular tube structure as well as any other kinds of structure.

Steel rope:
8mm diameter steel rope wrapped with anti-rust plastic,reinforced rope clip,with anti-skip turnbuckle screw tension and adjust the horizon of the fan, prevents shaking of the fan, absorb the vibration energy.

blade:
The blade is made of aeronautic Al-mg alloy material that passed T6 heat treatment process,it has high strength,highdurability,the cross section of the blade is propeller streamlined to ensure the best energy efficiency ratio. It is easy to clean after surface grinding and extremely oxidation treatment. It has low wind resistance and high efficiency,There are two reinforced tendons and over-reinforcing structure.the thinnest part is 2mm,and the thickest part is 5mm,so as to avoid fatigue loss of the blade.

Installation Diagram
 

* The height of the pharmaceutical workshop is more than 4 meters. It can be installed regardless of the structural steel structure, concrete structure, spherical grid structure or complex structure of the workshop; there are no special requirements for the installation site; it can be installed with or without traffic inside the workshop
