The Krupp Fluid KRN series spiral blower is a new generation product innovatively developed on the basis of the traditional KRP three bladed straight blade Roots blower.
Featuring optimized design lines, reduced exhaust pulses, smoother output, and significantly reduced noise (4-7 dBa lower than traditional ones);
The host adopts a front and rear dual oil tank lubrication design, which provides better lubrication effect and protects the bearings, thereby extending the service life of the fan;
The unique belt automatic tensioning system eliminates the need for frequent adjustment of belt tension, making the use process more convenient;
Specially designed soundproof chassis, integrated with the machine, easy to install, and better sound insulation effect;
The host, intake/exhaust system, motor, check valve, and safety valve are all concentrated in the soundproof chassis, with a reasonable structure and beautiful appearance;
The external oil level gauge and top mounted design of the intake filter element on the chassis are convenient for observation and maintenance.
Customized fan service, energy-saving and cost-effective, can be designed with explosion-proof, corrosion-resistant, high-precision filtration and other characteristics according to requirements to meet the needs of different customers;

　　Technical Specifications:

Airflow range: 1.5-602m3/min
Wind pressure range: 0.1-1.2Kgf/cm2
Media: Air and neutral gas

　　 Application scope:

Krupp fluid products are widely used in industrial fields such as municipal wastewater and textile printing and dyeing, leather and papermaking, pharmaceutical electronics, food and beverage, brewing and fermentation, chemical electroplating, steel metallurgy, cement and building materials, and thermal power generation.

1. Water treatment: aeration and oxygenation in sewage treatment plants, backwashing of water treatment plant filters.
2. Power plant: flue gas desulfurization, boiler gas desulfurization, fly ash transportation and ventilation
3. Dehumidification and drying, air assisted combustion, vacuum suction, gas transportation.

At the same time, Krupp Fluid also produces negative pressure vacuum pumps and a special Roots blower for transporting high-temperature and medium high pressure gases.
Its working principle is to use the low-temperature medium high pressure gas that flows back into the blower after passing through the cooling device to cool the temperature inside the blower.

　　 Technical Specifications:

Airflow range: 5-450m3/min
Wind pressure range: 1.0-1.5kgf/cm2
Vacuum degree range: -5000-7000mmAq
It can transport high-temperature gases at around 120 ℃.

　　 Application fields:

Krupp fluid products are suitable for continuous long-term operation in workplaces that transport high-temperature gases. Chemical factory, biological fermentation, high-pressure powder material transportation.
