Introduction
A kitchen ventilation fan is the exhaust airmoving device that drives the entire kitchen ventilation system — creating the negative pressure that draws cooking fumes, heat, and moisture from the kitchen through the exhaust hood and ductwork and discharges them outdoors. In commercial kitchen applications, the ventilation fan operates continuously throughout service periods in a demanding environment of elevated temperature, high humidity, and grease-laden airstream — conditions that require a fan built specifically for kitchen exhaust service rather than a general HVAC fan adapted to this use.
Yuede's kitchen ventilation fan range — part of the smoke extraction cabinet series — covers the full spectrum of commercial kitchen exhaust applications from small café kitchens (500 m³/h) to large institutional and hotel catering facilities (20,000+ m³/h per unit). Both backward-curved and forward-curved centrifugal fan designs are available, with direct-drive motors as standard and belt-drive options for larger installations. All models are available with VFD-compatible IE3 motors for integration into Yuede's demand control kitchen ventilation systems, and with 304 stainless steel impeller options for highly corrosive exhaust applications.

Application
- Restaurant Kitchen Exhaust: The universal application — driving cooking fume exhaust through hood, baffle filter, ESP purifier, and ductwork to rooftop or wall discharge. Fan selection is based on kitchen airflow calculation and system static pressure calculation — both of which Yuede can assist with.
- Integrated Kitchen Ventilation Units: Yuede's integrated range hood units include the fan as an integral component — selected and installed by Yuede to match the hood's specific airflow requirements and duct connection. Customers purchasing an integrated unit receive a pre-matched, pre-wired fan-hood assembly ready for duct connection.
- Kitchen Make-Up Air Supply Fan: Forward-curved centrifugal fans are commonly used as supply air fans providing make-up air to the kitchen — either as short-circuit supply integrated in the hood or as separate supply air units. Balanced supply and exhaust fan sizing maintains correct kitchen pressurization relative to adjacent dining areas.
- Variable Speed DCKV Applications: Yuede's kitchen ventilation fans with IE3/IE4 motors and VFD-compatible configurations serve as the variable speed exhaust and supply fans in DCKV systems, modulating airflow between 30–100% of design based on cooking load sensor signals from Yuede's intelligent controller.
- Fan Replacement in Existing Kitchen Systems: When an existing kitchen fan fails, the replacement must match the original fan's airflow, static pressure, and duct connection dimensions. Yuede's fan range covers common sizes and connection configurations encountered in the field, with custom impeller and housing options for less common specifications.
- Q: How do I select between a backward-curved and forward-curved kitchen ventilation fan?
- A: The key factors are system static pressure and priority between efficiency and compactness. If your system static pressure exceeds 300 Pa, backward-curved is the correct choice — it provides better efficiency and a non-overloading characteristic at higher pressures. If system pressure is low (below 200 Pa) and airflow volume is the primary requirement, forward-curved fans can deliver higher airflow in a more compact housing at lower cost. For variable speed DCKV applications, backward-curved is generally preferred due to its more favorable part-load efficiency characteristics.
- Q: How often should a kitchen ventilation fan impeller be cleaned?
- A: Impeller cleaning frequency depends on upstream grease removal effectiveness. With an effective ESP or other purification upstream, the impeller may only require cleaning annually. Without upstream purification, impellers in heavy-fry kitchens may require cleaning every 1–3 months. An imbalanced impeller (from uneven grease buildup) will cause increased vibration, bearing noise, and accelerated bearing wear — early indicators that cleaning is required. Yuede recommends quarterly visual inspection and cleaning as needed.
- Q: What is the expected service life of a Yuede kitchen ventilation fan?
- A: With regular maintenance (bearing re-greasing per schedule, impeller cleaning, annual belt tension check for belt-drive models), Yuede kitchen ventilation fans are designed for 15+ years of service life. The motor is the most common component requiring replacement — typically at 10–15 years depending on operating hours and ambient temperature. Replacement motors are available for all current model fans. Bearing replacement (typically at bearing L10 life of 40,000 hours, approximately 8–10 years at 14 hours/day operation) is a routine maintenance item that extends fan life indefinitely.
- Q: Can I operate two kitchen ventilation fans in parallel for higher airflow?
- A: Yes. Parallel fan operation is a standard technique for increasing system airflow beyond single-fan capacity. Two identical fans in parallel connected to a common discharge plenum deliver approximately 1.8× the airflow of a single fan (not 2× due to increased system resistance at higher total airflow). For parallel VFD-controlled fans in a DCKV system, both VFDs should receive the same speed reference signal to maintain balanced load sharing. Yuede can provide a parallel fan arrangement design with performance verification for your specific system airflow and pressure requirements.
