Air Handling Unit
FAH Series
A hygienic, airtight and quiet suspended air handling unit — from ducted comfort cooling to long-throw jet models that condition vast open spaces such as exhibition halls and airport terminals. Built on FRIMEC's founding belief that science can make a better world.

Unique Profile & Forced-Seal Panels
High-strength ABS composite profiles eliminate thermal bridging, while a labyrinth compression seal locks every panel tight.
- Air leakage ~9% of the Chinese GB limit for purification units
- Smooth arc inner walls — no hard-to-clean corners
- Adhesive-free fillet seal with a flat, dust-free interior
- Non-toxic, antibacterial, silicone-free sealant — ideal for aseptic spaces
Low-Noise Fans & Efficient Motors
Every rotating part is balanced and selected for smooth, quiet running over a long service life.
- AMCA-certified centrifugal fans with galvanized steel volute
- G4.0 dynamically balanced impeller, high-precision bearings
- Three-phase motors at Level-3 efficiency (GB 18613-2012)
- Powder-coated fan finish for added corrosion resistance
High-Effect Hydrophilic Coil
Open corrugated hydrophilic aluminium fins deliver high heat-transfer efficiency and resist acid, alkali and corrosion.
- Dedicated coil software selects the optimal coil for low air/water resistance
- Coil selection verified against US AHRI standards
- Large-handle exhaust valve at the coil's highest point
- Mould-flanged galvanized sheet protects the copper tubes
Long-Throw Jet for Large Open Spaces
Jet models replace the duct outlet with 1–3 round jet nozzles, delivering a horizontal air stream across high, wide spaces where ductwork is impractical.
- Jet range up to ~32 m (FAH120), defined distance up to 38 m
- Coverage width ≈ 0.4 × jet range per unit
- Jet nozzle sizes 315 / 400 / 500 mm, 1–3 nozzles per unit
- Ideal for halls, terminals, atriums, factories and warehouses
EC Digital Fans — More Than 30% Energy Saving
Digital models use outer-rotor EC motors with integrated frequency conversion for whisper-quiet, efficient operation.
- Saves more than 30% energy versus traditional AC fans
- Stepless 0–100% speed regulation via 0–10 VDC signal
- Zero-current soft start, low vibration and maintenance-free
- On-site adjustable static pressure; optional Modbus remote control
Local Start-up Cabinet & Intelligent Control Box
Choose the control level your project needs — from simple local operation to full building-automation integration.
- On/off with local / remote control and run, power & fault indicators
- Dry contacts ready for remote BAS monitoring
- Factory-fitted controller modulates the coil valve to hold room temperature
- Optional RS485 link; fire-damper and air-damper interlock available
Ready for F&B Environments
Designed with commercial kitchens in mind, where heat, grease and oil are always present.
- Optional aluminium mesh filter captures oil and grease before the coil and fan
- Washable and reusable filter for easy maintenance
- Keeps internal components clean and coil performance steady
- Reliable comfort for restaurants, food courts and central kitchens
Where the FAH Performs Best
From compact ducted installations to long-throw jet units, the FAH range fits buildings of every scale — especially large, high-ceiling spaces where ductwork is costly or impractical.
Exhibition & Convention Halls
High ceilings and wide floor plates — jet models cover long distances without ductwork, keeping booths and visitors comfortable.
Airports & Terminals
Departure halls, check-in areas and concourses that need steady comfort across large, open volumes.
Malls & Atriums
Retail floors, atriums and lobbies.
Factories & Warehouses
Production areas and logistics halls.
Sports Halls & Auditoriums
Arenas, gyms, ballrooms and places of worship.
Offices & Hotels
Ducted comfort cooling and fresh-air supply.
Restaurants & Kitchens
Grease-ready with aluminium mesh filter.
Clean & Hygienic Spaces
Airtight, antibacterial interior for clinics and labs.
Additional Plus-Point Features
Dry Antibacterial Drain Pan
Patented design drains water thoroughly; its angled shape reduces resistance for lower energy use.
Motor Bolt Pressing
Patented pressing joins fan plate and motor without damaging the galvanized coating.
Galvanized Fillet Structure
Rounded, powder-coated sheet-metal corners for safer handling and a cleaner finish.
Plastic-Coated Metal Hose
Light, flexible and insulated protection for motor cables, resistant to wear and corrosion.
AHU Selection Software
Calculates every section to your conditions and auto-generates data, drawings and reports.
Optional Wet-Membrane Humidifier
Evaporative humidification section in 50–200 mm thickness to match the required capacity.
