The "YingTeng" explosion-proof air curtain series has been processed with special explosion-proof technology, making it suitable for 1 and 2 explosive and flammable areas. It is widely used in scientific research, oil, chemical, pharmaceutical, and power plant environments where there may be or could be II A, II B, T1-T4 group combustible gases, vapors mixed with air, posing explosion hazards. Explosion-proof air curtains are ideal for areas with temperature requirements. They have passed inspections by the National Quality Supervision and Inspection Center for Explosion-Proof Electrical Products and received explosion-proof certification and CCC certification. The air curtains are aesthetically pleasing, well-designed, and easy to install and maintain. They feature microcomputer intelligent control, digital display, low noise, stable performance, simple operation, and reliability, earning them popularity in the market. (Customizable options include electrically heated explosion-proof air curtains, vertical explosion-proof air curtains, axial flow explosion-proof air curtains, centrifugal explosion-proof air curtains, etc.)

The Yinteng explosion-proof air curtain operates normally under the following environmental conditions:
a) Altitude not exceeding 2,000m.
b) Suitable for environments with temperatures ranging from -7℃ to 43℃, free from corrosive gases.
c) There are explosive hazardous areas formed by mixtures of flammable gases, vapors, and air in Class II A, II B, and T1 to T4 groups.
Explosion-proof air curtain machines are specially designed for environments where flammable gases, vapors, and air mixtures (IIA, IIB class, T1~T4 groups) are present, which are highly prone to explosion. These are commonly used in research, oil, chemical, pharmaceutical, manufacturing, and biological industries. They are engineered for areas requiring temperature control and are processed with special explosion-proof technology.
Industrial-grade explosion-proof air curtains are suitable for installation in high places such as factories and warehouses. They effectively block out temperature differences, dust, bodies, insects, and other harmful substances from the outside, maintaining indoor environmental temperature and cleanliness.
This industrial explosion-proof air curtain unit features a centrifugal forward-bent blade impeller structure, paired with an efficient spiral casing design, resulting in excellent fan performance. This type of impeller is highly efficient, low-noise, with low airflow and high pressure, surpassing any other air curtain unit. It can form an ideal air curtain.
The industrial centrifugal fan is made of all-metal construction, featuring high fire resistance, a compact overall structure, easy installation, simple cleaning, and maintenance.
Lightweight and ultra-thin body design, all-metal shell, direct honeycomb-style air intake, and integrated one-piece air outlet panel for easy assembly and disassembly.
