Dear friend:
Glad to know you in our website, are you still buying from products from TRADING COMPANY? Are you still buying from small factory and the quality is not guaranteed? From now on, you do not have to do that, because you have found a reliable supplier-DONGSEN, our factory can offer you all kinds of power tools, welding machines, air compressors.
Now I would like to show you some pictures of our factory, so that you can have a better understanding about us:
1. Firstly, is an overall view about our factory, covers an area of 100,000 square meters, more than 600 workers working here.
2. Second is our workshops, all of importants parts are made by our own factory, which will control our quality very well:
a. Pictures of Injection workshop, mainly in charge of manufacturing housing, handles etc:
b. Pictures of metal workshop, for all kinds hardware parts:
c. Motor Workshop, as we all know, rotor and stator is most important parts for power tools, our facotory aware this and purchase many advanced devices, to improve the quality of motors:
d. Assemblying lines, each line only major in one item product, like A1 line only manufacture drills, which helps our staff more professional:
e.Testing lab, before we send products to customers, every product will be strictly tested, below is some of our testing instruments:
f. Warehouse:
3. About after-sale service, we can offer you 12 months guarantee, and supply you all spare parts you need in future. The purpose doing this is to establish long-term cooperation, win-win strategy is what our factory looking forward.
So dear friend, if you are interested in our factory also advice on us, pls mail us, we will do our best to help you.

i, High-pressure Roots Blower Low noise
550W Electric mini air Blower;hot air blower;small air blower with adoption of helical tri-lobe roots rotors and the discharge port of special geometry, the airflow noise is much lower compared to typical straight-lobe roots blower. The noise level can be reduced by 8db in the band of low frequency; hence the noise in the surroundings of blower can be significantly improved.

ii, High adiabatic efficiency
High-pressure Roots Blower with design of helical tri-lobe roots rotors, 550W Electric mini air Blower;hot air blower;small air blower the airflow pulsation is less and the air streamline would be more stable. Therefore the fluctuation in airflow is less and then the energy waste can be reduced. Additionally, the instantaneous backflow of discharge is lower by the design of special discharge port. Compared to straight-lobe roots blower, the adiabatic efficiency can be raised up to 20%.

iii, High-pressure Roots Blower Super Energy saving
Compared to the typical550W Electric mini air Blower;hot air blower;small air blower under the same operation conditions of discharge pressure and airflow volume, the power consumption of helical tri-lobe roots blower will be lower by 20.
