Longgu explosion-proof Roots blower is a type of Roots blower designed by our company to adapt to the transportation of flammable and explosive special gases such as hydrogen and natural gas. This series of explosion-proof Roots blowers is safe and reliable, with advanced design, strict quality assurance, and comprehensive and rich configuration. The Longgu explosion-proof Roots blower adopts a fully closed structure, optimizing all possible leakage points. It is specially designed for low molecular weight hydrogen, high moisture content biogas, highly corrosive hydrogen sulfide, and high pressure natural gas transportation. It has strong adaptability, safety and reliability, and uses explosion-proof motors to eliminate electrical hazards and avoid potential safety hazards in dangerous gas transportation.

Dragon drum explosion-proof Roots blower can be used to transport flammable and explosive special gases such as biogas, coal gas, hydrogen, natural gas, etc., with good sealing and anti-corrosion properties.


1. Special materials for production
Explosion proof Roots blowers have special requirements for materials. If there are no special requirements, they will also undergo secondary operation on ordinary materials to make them have explosion-proof and anti-corrosion properties.
2. Special treatment
In terms of explosion prevention, special selection and treatment are required for materials, and special treatment is even more necessary for corrosion prevention. When facing high temperature, high humidity, and high acidity/alkalinity environments, fans will undergo special treatment. Therefore, we have seen many explosion-proof and anti-corrosion fans undergo special treatment.
3. Good sealing performance
The Longgu explosion-proof Roots blower adopts explosion-proof and anti-corrosion function fans, which generally transport flammable and explosive gases. Whether it is Roots blower or other types of fans, there are high requirements for sealing. Poor sealing can lead to potential safety accidents. Secondly, if it is a rare gas, poor sealing can also cause waste of resources. Therefore, sealing cannot be underestimated.
4. Good sealing performance
The two ends of the rotor bearings of the Longgu explosion-proof Roots blower and the connection with the oil tank are treated with good sealing technology, which can effectively prevent the reaction between gas and oil in the oil tank, as well as prevent the leakage of special gases such as biogas, coal gas, hydrogen gas, and natural gas, thus avoiding safety accidents.
5. Good corrosion resistance
The Longgu explosion-proof Roots blower is mainly made of stainless steel material, and other anti-corrosion materials can also be used according to customer requirements. All stainless steel materials can be used, or a layer of stainless steel material can be coated on the surface to reduce procurement costs.
1. Featuring unique technology and structure: The Longgu explosion-proof Roots blower adopts a spiral structure for the inlet and outlet of the fan. The inlet and outlet gradually move with the rotation of the rotor, avoiding pulsation and noise caused by instantaneous opening and closing. The operation is smoother and more reliable, with less vibration and a longer service life of the fan;
2. Low noise: The Dragon Drum explosion-proof Roots blower is equipped with a silencer, sound-absorbing material, and special structure, resulting in low noise.
3. Smooth operation and low vibration: The explosion-proof Roots blower impeller and box are precision machined, with uniform and consistent rotor mesh clearance, good component coordination, and the rotor undergoes more precise dynamic balancing experiments, resulting in low vibration during fan operation.
4. Low energy consumption and high efficiency: The rotor of the Longgu explosion-proof Roots blower adopts a special design, and the meshing curve is an advanced composite line, which further improves the volumetric efficiency, seals well, and has less leakage.
When customers purchase Roots blowers, in addition to focusing on the performance and quality of the equipment itself, the price is undoubtedly a concern for them. Especially for equipment with many manufacturers in the market, it is even more important to be cautious when purchasing, as the price of a Roots blower is not cheap.
In general, the price of Roots blowers is influenced by various factors, such as equipment manufacturer, specifications, quality, region, market demand, etc. Different Roots blower manufacturers have different product performance and quality, and prices also vary. Therefore, customers must purchase equipment from legitimate manufacturers, such as Shandong Longgu Heavy Industry. Industry focus, guaranteed technology, and more cost-effective equipment quotes provided. Specific prices can be consulted online for free.
