In brief

What is the TAT LDSF steel square exhaust fan?

The TAT LDSF series is a Korean-engineered steel square wall exhaust fan designed to develop high static pressure (8 to 25 mmAq / 78.5 to 245.2 Pa) and deliver 600 to 4,770 CFM at 60Hz. It features an aerodynamic bellmouth inlet and continuous-duty motor (-10°C to +55°C) to maintain stable airflow through gravity shutters, rain louvers, and short ductwork.

Application Check

Is the TAT LDSF series suitable for your facility?

Evaluate required static pressure, wall opening cutout, ambient operating conditions, and airstream type before finalizing your selection.

Good fit
  • Commercial workshops, fabrication bays, and industrial maintenance areas
  • Warehouse storage bays requiring wall exhaust through external gravity shutters
  • Wet markets, produce/fish distribution halls, and high-humidity utility rooms
  • Restaurant dining rooms, dishwashing areas, and general food prep rooms (ambient)
Confirm first
  • Operating static pressure against exterior louvers or short ductwork (< 80–245 Pa)
  • Wall opening rough-in cutout dimensions (260×260 mm up to 575×575 mm)
  • Continuous ambient temperature within manufacturer bounds (-10°C to +55°C)
  • Adequate fresh make-up air intake path (door louvers or transfer grilles)
  • 220–240V 60Hz 1-phase electrical power connection
Use another documented fan
  • Commercial kitchen grease exhaust hoods (select Upblast Roof Fan or Centrifugal Box Fan)
  • High-CFM agricultural poultry sheds and open barns (select DEMO HAM Series)
  • Long high-resistance ducted ventilation networks (select Inline Duct Fan or Centrifugal Blower)
  • Explosion-proof or ATEX-classified flammable solvent or spray painting booths
Important application note: TAT LDSF series steel square wall fans are high-pressure wall exhaust units engineered to overcome system resistance from gravity shutters, exterior louvers, and short ductwork (8 to 25 mmAq). They are suitable for ambient restaurant dining and prep ventilation, but are NOT certified for commercial kitchen grease exhaust hoods.

Catalog & Saudi 60Hz Note: Performance values are based on authentic TAT / Alhakbani LDSF Korean manufacturer catalog ratings. For Saudi Arabia projects, 220–240V 60Hz 1-phase ratings apply (highlighted in red above). Operating at 60Hz increases nominal motor RPM and provides higher airflow against rated static pressure (8 to 25 mmAq / 78.5 to 245.2 Pa). Continuous operating temperature: -10°C to +55°C.
Aerodynamics & Pressure Head

Bellmouth Aerodynamics & High Static Pressure Head (8 to 25 mmAq)

Deep-drawn inlet curvature and high-pressure impeller engineering ensure stable airflow under resistance.

Bellmouth Aerodynamic Inlet
Deep-drawn bellmouth frame eliminates sharp inlet edges, reducing entry vortex separation and generating higher pressure recovery with lower operating turbulence.
High Static Pressure (8 to 25 mmAq)
Rigid formed steel impeller blades develop high pressure heads (78.5 to 245.2 Pa), preventing airflow collapse when discharging through gravity shutters or insect screens.
LDSF Shutter Integration
Automatic gravity-drop shutter louvers open smoothly under fan velocity pressure and drop closed when turned off to prevent outdoor backdraft, dust, and rain entry.
Saudi 60 Hz Motor Optimization
Heavy-duty 4-pole motor operates at 1360 to 1650 RPM on Saudi 60Hz power, delivering 600 to 4,767 CFM across 7 distinct sizes from 8-inch to 20-inch.

Applications

TAT LDSF Wall Exhaust Fan Applications

High-pressure air extraction across commercial workshops, industrial warehouses, wet markets, and restaurant dining/prep rooms.

Commercial workshops

Removes: Heat buildup, light fabrication fumes, and dust-laden air from maintenance bays

Industrial warehouses

Removes: Stagnant heat and stale air across storage aisles through exterior wall openings

Wet markets & produce halls

Removes: Moisture, humidity, and food odors in demanding commercial retail environments

Restaurant dining & prep areas

Removes: Dining room heat, prep area moisture, and general ambient odors (NOT grease hoods)

Commercial laundry rooms

Removes: Equipment heat dissipation, steam, and high humidity from washing and drying areas

Electrical & plant rooms

Removes: Heat generated by transformers, switchgear, and elevator equipment

Agricultural ventilation

Removes: Humidity and stagnant air in farm utility sheds and livestock service areas

MEP project procurement

Removes: Sized by required CFM at static pressure, wall opening cutout, and 60Hz power supply

Application boundary: TAT LDSF fans are high-pressure wall exhaust units. For commercial kitchen grease hoods, select a certified metal Centrifugal Box Inline Fan or Upblast Roof Fan. For high-CFM agricultural poultry sheds or greenhouses, select the DEMO HAM Shutter Exhaust Fan.
