Commercial Kitchen Extraction
& Fresh Air Systems

Code-compliant canopy hoods, grease ducting, makeup air supply, and positive-pressure ventilation built for Auckland kitchens, hospitality sites, and commercial buildings.

Commercial Kitchen Canopy Exhaust Hoods

Commercial Kitchen Canopy Exhaust Hoods

Heavy-duty stainless steel extraction hoods built to handle high-heat commercial cooking lines. We fit thermal fire dampers, washable baffle filters, and high-velocity fan motors engineered to satisfy Auckland Council health regulations and AS/NZS 1668.2 fire safety rules.

  • Washable Stainless Steel Baffle Grease Filters
  • Automatic Thermal Fire Damper Interlocking
  • High-Velocity Discharge Ductwork (AS/NZS 1668)
Fresh Air Makeup & Heat Recovery (HRV/ERV)

Fresh Air Makeup & Heat Recovery (HRV/ERV)

Sucking massive volumes of air out of a commercial kitchen without supplying fresh makeup air creates negative building pressure. That leads to slamming doors, drafty dining rooms, and starved exhaust fans. Our balanced makeup air systems supply clean, filtered outside air while recovering waste heat to keep running costs down.

  • Balanced Supply Fans with Variable Speed Drives (VSD)
  • Active Condensation & Mould Prevention
  • High-Efficiency MERV Air Filtration Cells
CLAUSE G4 CALCULATOR

Kitchen Canopy Airflow Rate Estimator

Estimate your required extraction volume in Litres per Second (L/s) to meet NZ Building Code Clause G4 and AS/NZS 1668.2 standards.

Estimated Extract Volume Required
L/s
(Equivalent to ~ CFM)

Note: Calculated against NZ Building Code Clause G4 capture velocity baseline. High-heat charbroilers, woks, or solid-fuel cooking plant require a custom on-site calculation.
