BSTQ Type Pneumatic Explosion-Proof Fan
Product Description
BSTQ Type Pneumatic Explosion-Proof Fan
Product Introduction:
The BSTQ Series Pneumatic Explosion-Proof Fan is specially designed for ventilation applications in potentially explosive atmospheres, such as chemical plants, oil refineries, paint workshops, offshore platforms, and confined spaces where flammable gases, vapors, or dust may be present.
Powered entirely by compressed air, this fan requires no electrical connection, eliminating the risk of electrical sparks that could ignite explosive media. Its air‑motor drive system ensures safe, maintenance‑free operation even in the most demanding conditions, making it an ideal choice for Zone 1, Zone 2, and other hazardous area classifications.
Key Features:
1.Explosion‑Proof by Design – No electrical components; zero spark risk for maximum safety in volatile environments.
2.High Airflow Performance – Delivers airflow ranging from 2,100 to 17,700 m³/h, with air pressures up to 300 Pa, meeting diverse ventilation requirements.
3.Low Air Consumption – Operates on just 1.0 to 2.2 m³/h of compressed air, offering excellent energy efficiency.
4.Robust Construction – Built with durable materials and available in multiple sizes (8" to 28") to suit different installation spaces.
5.Adjustable Speed – Rotation speeds from 1,200 to 3,000 r/min provide flexible control over ventilation intensity.
6.Easy Installation – Lightweight and compact design with standardized dimensions (L = 360 mm across all models) simplifies integration into existing systems.
7.Low Maintenance – Pneumatic drive reduces wear parts and eliminates the need for complex electrical upkeep.
