What is the difference between manual and automatic non pressure dampers?

  What is the difference between manual and automatic non pressure dampers? We all know that quality can overcome everything, but nowadays people don't care much about it
It seems that they pay more attention to price
In this era, a hundred yuan can be spent casually, so most people's concept of money is that the less money they spend, the better things they can buy
However, the fact is not necessarily the case
If you think less and spend more, it is impossible
Research and development needs money, The same steel plate also needs money
The cost is there, so there will be no low price and high-quality products at the basic price
No one does business without making money
Therefore, as long as the quality is good, everything can be negotiated,
The manual non pressure damper is named as manual, and the door must be closed manually
The full-automatic non pressure damper is full-automatic, which can be equipped with full-automatic pneumatic, full-automatic hydraulic and pure electric
When a miner or mine car passes by, the damper will automatically open after induction, and the damper alarm will be realized
This is the main difference between the two dampers

No matter what kind of non pressure damper our customers buy, we can produce it and guide the installation
