(1) Features and Uses The D series multi-pole centrifugal blowers can be used to transport air, gas and chemical gases. They have low noise, small vibration, high efficiency, stable operation, convenient installation and maintenance, use in open air environments, etc. Features. Commonly used in blast furnace blasting, desulphurization blasting in power plants and refineries, coal preparation jigs, blast furnaces, coke oven gas, pressurized transportation, and blast aeration for sewage treatment, chemical gas recovery, and pressure delivery. In the same industry, our products have the unique features of wide range of user selection and complete facilities.

(2) Type D - single suction fan inlet XXX - inlet volume flow under standard conditions (m3/min)
X - Number of impeller stages X - Design number XX - Absolute outlet pressure (kg/cm2)
Example: The definition of D300-31-1.5 is: The first designed intake air is a single-suction, 3-stage centrifugal blower with a flow rate of 300m3/min at 20°C, an absolute pressure of 101.325kPa, and a relative humidity of 50%. , The absolute pressure at the outlet is 1.5kg/km2 (gauge pressure is 49kPa)
