Technical Specification |
Description / Typical Range |
Material of Construction |
Standard: SS 304 / SS 316 (Stainless Steel) for high corrosion resistance. Alternate: Galvanized Steel, Polypropylene (PP), or PVC for specific chemical environments. |
Air Volume / Flow Rate (CFM) |
Light-Duty: 150-250 CFM/ft of hood length. Medium-Duty: 250-400 CFM/ft. Heavy-Duty: 400-600+ CFM/ft. |
Capture Velocity |
Minimum: 100 FPM (0.5 m/s) at the hood face for effective containment. Typical: 150-200 FPM (0.75-1.0 m/s) for processes with moderate turbulence. |
Duct Velocity |
Recommended: 1,500 - 2,500 FPM to ensure proper conveyance of contaminants and minimize static pressure loss. |
Static Pressure |
Varies based on system design, typically ranging from 1 to 4 inches of water gauge (w.g.) depending on the length of ducting and number of elbows. |
Fan / Motor Type |
Fan: Heavy-duty centrifugal fan for high static pressure systems. Motor: TEFC (Totally Enclosed Fan Cooled) motor, 3-Phase, with IP55 protection. |
Motor Power (HP/kW) |
Custom calculated based on the required CFM and static pressure of the entire ventilation system. |
Filtration System |
Type: Baffle filters for grease and oil vapor, mesh filters for coarse particles. Optional: HEPA filters, activated carbon filters for specific fumes and odors. |
Sound Level (Noise) |
Operational Noise: < 80 dB at 1 meter. Noise Reduction: Provided by acoustic insulation on the fan and ducting. |
Power Supply |
240/415V AC, 50 Hz, Single or Three-Phase, as per the motor requirement. |
Hood Dimensions |
Standard: Custom-sized as per application, with a minimum 6-inch overhang on all sides of the heat or contaminant source. |
Integrated Features |
Lighting: IP65 rated, vapor-proof LED lights for illumination. Controls: ON/OFF switch with optional VFD (Variable Frequency Drive) for fan speed control. |
Safety & Compliance |
Certification: UL Listed (UL 710) for commercial applications. Compatibility: Pre-piped for compatibility with a fire suppression system. |
