Pneumatic Explosion Proof Fans, Model PTF-300, PTF-400

1. General:

Teryair Pneumatic Turbine Fans are designed for high-performance gas ventilation from large, enclosed areas or other tank openings. Works effectively, providing penetration deep into the tank for complete ventilation. These fans are made of non-spark construction using ATEX Air motors. These components are manufactured from Aluminum and bronze material. Driven directly by compressed Air, this ventilator depends on other power with sealed bearings; it largely reduces maintenance. With wide applicability, this type of ventilator can work at ambient temperatures of﹣20℃ to +40℃, ideal for ducting flammable and explosive gases or steam as well as poisonous or other harmful gases.

2. Structure:

Teryair Pneumatic Explosion Proof Fans are composed of Air Motor, frame, casting, grill etc. The casing is cast from high-strength aluminum alloy whole structure of the no-spark design. The Pneumatic fan is cast from SG Iron. The fan blades are aluminum.

The fan blades are aluminum, so there is safety from sparking even when fan blades collide with the casing.

3. Application Conditions:

For areas that are exposed to explosive gases II and IIC group Temperature ClassT6

Ambient temperatures: -20℃~40℃

4. ATEX applicable code can be:

II 2G Ex h llC T6 Gb (for gas group)

II 2D Ex h lllC T85°c Db (For dust group)
