Explosion-proof blowers are suitable for conveying flammable, explosive and non-corrosive gases. The ambient temperature should not exceed 60℃. Generally widely used in factories, warehouses, offices, residential ventilation or strong heat heating. Long exhaust pipes are also available. Explosion-proof blower internal interval series installation, increase the pressure in the pipeline, remove the motor can be used as a free blower.

Explosion-proof blowers are suitable for conveying flammable, explosive and non-corrosive gases. The ambient temperature should not exceed 60℃. Generally widely used in factories, warehouses, offices, residential ventilation or strong heat heating. Long exhaust pipes are also available. Explosion-proof blower internal interval series installation, increase the pressure in the pipeline, remove the motor can be used as a free blower. The distance between the shell of the exhaust blower and the wall or equipment should not be less than 60cm. If the location of the smoke exhaust blower is fire-resistant structure, and when the heat is transferred to the surrounding, no accident will occur, at this time, the outer shell can not be insulated. Explosion-proof blowers are suitable for conveying flammable, explosive and non-corrosive gases, and the ambient temperature does not exceed 60℃. Widely used in general factories, warehouses, offices, residential ventilation or strong heat heating. It can also have longer intervals in the exhaust pipe. Series installation to increase the pressure in the pipeline, motor removed motor can be used as a free blower. Explosion-proof blowers are made of anticorrosive materials and coated with epoxy paint. The motor adopts special anticorrosive motor to transport corrosive gas.


Explosion-proof blower is used to transport flammable and explosive gas, suitable for the temperature group of T1 ~ T4 environment; The impeller is made of aluminum alloy to prevent sparks when running. The motor is explosion-proof. See is smoke exhaust blower or usually ventilated! It is best to set aside space for installation and maintenance if it is a smoke exhaust blower, please note that if the blower is not placed in a special machine room to set up fire insulation treatment! It has the characteristics of high strength, light weight, good corrosion resistance, not easy aging, low noise, and is an ideal anti-corrosion and anti-explosion blower.

Here are four precautions for the installation of Explosion-proof blowers:
1. Sufficient space should be left around the cabinet machine, especially on the side of the access door, for the use of equipment inspection and maintenance. (greater than 500mm).

2. When installing the wind cabinet, there should be a vibration damping device, and when installing the power distribution, there should be a motor protection device. The motor above 7.5kW should be equipped with step-down starting

3. The suspended ceiling cabinet centrifugal blower shall be lifted horizontally and kept in a horizontal position, which is firm and reliable. Floor mounted blowers should be placed on flat bases.

4. The floor or platform directly equipped with ventilators should adopt cast-in-place reinforced concrete slabs with a thickness of no less than 80mm, and cold-rolled steel bars should not be used.

Installation instructions for explosion-proof blower:

1. Before installation, check whether the blower is damaged or deformed. If there is damage or deformation, it must be properly repaired before installation.

2, the requirements of the installation environment, first of all, we need to clean the surface of the foundation concrete, and check its levelness, and then put the explosion-proof blower base on the foundation, insert the pad iron between the foundation surface and the base surface, the gap only needs to ensure the inflow of mortar.

3, when installing the explosion-proof blower, pay attention to check whether the connecting piece is loose, the gap between the blade and the air channel should be uniform, and no collision.

4, when we install the precision requirement of higher explosion-proof blower, you should put the grout injection buried anchor bolt hole, after being its fully hardened, alignment, adjustment for level again, after installation accuracy is achieved in the grout injection base and foundation stick again the clearance between the coagulation soil, wait for mortar fully hardened, tighten the anchor bolt nut.

5. The weight of the connected tuyere pipe should not be borne by the air duct of the blower, and the support frame should be installed during installation.

6, in some cases, because it is impossible to set enough foundation, Explosion-proof blowers are often installed on the shock absorber to reduce the transmission force of vibration.


The shock absorber should be arranged with the center of gravity of the explosion-proof blower to ensure that the compression of the shock absorber is consistent. 7. The anchor bolt hole through the base should be perpendicular to the square hole of the anchor bolt, and the gap between the anchor bolt hole and the base and the foundation concrete should be filled with enough mortar to ensure the strength of the concrete structure. 8. The outlet end of the explosion-proof blower needs to install an air collector, and it is hoped to install a protective net. 9. The blower base must be naturally connected with the foundation plane. Do not forcibly connect the base to prevent deformation of the base. During installation, adjust the base, add the iron plate, keep it basically horizontal, and then tighten the anchor bolts. 10. After the installation of the explosion-proof blower, it is necessary to conduct experiments before it can be used formally until it runs normally.
