| Title | Purchase of Inline (Duct) Exhaust fan With Installation |
| Description | TECHNICAL SPECIFICATION: INLINE (DUCT) EXHAUST FAN 1. General Description The inline exhaust fan shall be suitable for continuous ventilation of air through ducting systems in laboratories. The fan must be designed for low noise operation, high efficiency, and reliable continuous duty. For laboratory applications involving corrosive fumes, units constructed from high-grade polypropylene (PP) or PVC are highly recommended for chemical resistance. 2. Type Type: Inline/Duct-mounted, mixed-flow, or centrifugal exhaust fan Installation: Mounted inside ventilation duct (can be installed in any position/angle) Airflow direction: Single direction Application: Exhaust ventilation (e.g., fume hoods, general lab exhaust) 3. Air Performance Airflow capacity: ≥ 300 m³/h (cubic meters per hour) Static pressure: ≥ 100 Pa (Pascals) - Centrifugal or mixed-flow designs work best against the high static pressure of long or complex duct runs. Fan speed: Single speed/Multi-speed (speed adjustable via optional controllers) Airflow efficiency: High-efficiency design, often achieved with external rotor motors and backward-curved impellers. 4. Electrical Characteristics Power supply: 220-240 V AC, 50 Hz (or as per local standard) Power consumption: ≤ 100 W (typical of high-efficiency models for this airflow range) Motor type: Single-phase, maintenance-free motor, external rotor motor with sealed-for-life ball bearings for long operational life (e.g., 30,000 to 50,000 hours). Insulation class: Class B or higher (Class F is also available on some models). Protection class: IP44 or higher (IP55 engine is available for enhanced protection against water and dust ingress). 5. Construction & Materials Casing material: High-grade corrosion-resistant pressed galvanized steel or industrial-grade, self-extinguishing ABS/PP plastic, depending on the chemical resistance requirements of the laboratory environment Impeller: Backward-curved centrifugal or mixed-flow design Shaft & bearings: Sealed ball bearings for continuous operation Corrosion resistance: Suitable for humid environments 6. Noise Level Sound level: ≤ 45 dB(A) measured at 1 meter Design must ensure low vibration and quiet operation 7. Duct Connection Duct diameter: 150 mm or 200 mm Connection type: Circular duct connection Must be compatible with standard HVAC ducting 8. Operating Conditions Operating temperature: -10°C to +60°C Continuous operation: Suitable for 24/7 use 9. Safety & Standards Compliance with relevant IEC/ISO/CE standards Overheating protection included Electrical safety certified 10. Accessories (if applicable) Mounting brackets Flexible connectors Back draft damper (optional) Speed controller (optional) 11. Warranty & Support Minimum warranty: 12 months Availability of spare parts: Minimum 5 years Local service support preferred 12.
