Mining Ventilation Positive Pressure Blower / Clean High Pressure Roots Blower



Description of Performance parameters


The performance parameters table shows the model, outlet diameter, rotate speed, discharge pressure, air capacity and power of motor.

1. The air capacity and pressure in the tables is in standard suction state. The standard suction state is 20ºC temperature, 1.033 kgf/cm2(101.3Kpa) Standard atmospheric pressure and 65% relative humidity.

2. The air capacity and pressure range of some blower models is repeated, to ensure the service life and low noise, should use the larger model.

Roots Rotary Blower Application

Water Treatment Aquaculture Powder and granules
transportation
Be used in water treatment plant for water purification and sediment mixing Be used in a variety of fish pond for oxygen supply and mixing, and also for aquariums and live fish tank Powder or granules
(such as plastic materials, etc.) can be transported by pressure or vacuum
Incinerator Ballast pump Sandblast
Air combustion and exhaust emissions Used for chemical liquid unloading and other ballast pumps Used as air source for blast jet
Booster Compost fermentation Cereals Transportation
Used for high-pressure exhaust to make the gas into tiny molecules High-pressure air take into the livestock manure tank to increase contact area of livestock manure and air , also apply to sewage treatment Cereals such as wheat are transported from the rotary pilot valve with air
Pipe clearing Sauna Plating Bath
Used to remove dirt and iron dust during pipeline replacement or overhaul Used for the sauna to provide air bubbles, mainly used for hospitals, hotels and etc. Use air to stir the electrolyte to keep the electrolyte circulation, and disperse the attached blister to make plating quickly, spread evenly
Produce line drying Car wash dry Smoke exhaust
Quickly remove the water or oil on the cleaned items Dry the car after washing Exhaust smoke quickly to reduce pollution
Feed paper/cloth Washing machine
blow dry
Gas /heavy fuel injection
Collect plastic, cloth, paper and other scrap generated after trimming Dried bottles after washing, suitable for food industry Provide high pressure (2000 mmAq) and sufficient air volume
