Shandong Mingtian Machinery Co.,Ltd products

Adopting high-precision gears and bearings not only makes the life prolonged, but also realizes low noise. The inlet and outlet of this fan adopts a unique reflux structure, so the running sound is extremely small and there is almost no pulsation of exhaust air.

Many varieties and specifications, including positive pressure, negative pressure, dry type and wet type, featuring dense flow rate classification and convenient selection for users.

Adoption of advanced driving gears not only makes life longer, but also realizes low noise. The air inlet and outlet of this fan does not open or close instantly like the old fans, so the running sound is extremely small and there is almost no pulsation of the exhaust air. The output air is clean and does not contain any oil dust.

Adopting a number of patented technologies such as counter-flow device, with reasonable structural design. Impeller adopts specially designed three-leaf composite type line with high efficiency. High processing precision of key parts ensures the blower (vacuum pump) running smoothly. The unique cooling and sealing structure makes the blower (vacuum pump) obtain higher compression ratio.

For reasons of efficiency and temperature rise, single-stage blower pressure ratios are generally limited to under 2.2. In order to achieve higher pressure ratios, two blowers are usually connected in series to form a two-stage tandem blower. In this case, the two-stage tandem Roots blowers are equipped with an intercooler between the two stages.

For reasons of efficiency and temperature rise, the pressure ratio of single-stage vacuum pumps is generally limited to 2.2. To achieve higher pressure ratios, two vacuum pumps are usually connected in series to form a two-stage tandem vacuum pump. In this case, the two-stage tandem Roots vacuum pump requires spray water cooling.
