Since 2008 we've shipped over 380,000 blowers to 60+ countries. Every unit we make is built by a single accountable team — from the rotor casting to the final vibration test — and shipped from one address in Dongguan, China.
We're not a trading company. We're the people who cast the rotors, wind the motors, balance the impellers and sign the warranty — under one roof, under one name.
Each rotor is cast, annealed and dynamically balanced on our own line. No trading-house markups, no surprises when you need spare rotors in year four.
Every standard build uses an IE3 / NEMA Premium motor wound for the exact rotor characteristic curve, not a generic catalogue motor.
No blower leaves the factory without a continuous-duty test at its nameplate flow + pressure on our calibrated test bench. The printout is in the crate.
Our 38 application engineers (out of 215 staff) will size the blower, pick the accessories and draw the layout for your specific duty.
From raw castings to balanced, test-certified units — filmed in our own workshop. This is where your blower is built.
When you email sales, you reach one of these people. Not a queue.
