GGHGA
i,medium-pressure roots blower/ Three-lobe vertical roots pump parts Low noise
three lobe roots 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.
HDHSD
ii, medium-pressure roots blower/ Three-lobe vertical roots pump parts High adiabatic efficiency
three lobe roots blower with design of helical tri-lobe roots rotors, 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.
SSFFS
iii, medium-pressure roots blower/ Three-lobe vertical roots pump parts Super Energy saving
three lobe roots blower Compared to the typical roots 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.

Product Description
| Purchase notes: |
2. The offer for a single host price, excluding motor.
3. Special work requirements can be corrosion, sealing, high-pressure, intensive and other forms.For further details, please contact customer service.
| Product Application |
In terms of application, most of roots blower for the use of air blower. Their use in building materials, electric power, metallurgy, chemical and petrochemical, can be used to transport air outside of the gas, such as hydrogen, industrial oxygen, carbon monoxide, carbon dioxide, hydrogen sulphide, methane and acetylene, coal, etc.
| Blower working principle |
With the mutual engagement of the two gears, the inlet and outlet of the blower are not communicated directly. The impeller and the casing and the wall plate are enclosed into the base unit volume, so as to achieve the effect of conveying gas.
| Main Features |
2. The selected motor is generally 4 motors, voltage 380V.
3. When the boost is greater than 63.7kPa, it is a high pressure fan, marked as NSR- II -H.
4. NSR- II series Roots blower standard with double fuel tank.
5. When 73.5kPa6. Fan tank water cooling water consumption is 8-10L/min, the cooling water inlet temperature is not higher than 25 DEG C, the inlet pressure is 196kPa (tap water pressure can)
