Quick technical answers regarding the LWKXF series oil smoke exhausting centrifugal fan.
What is the primary application of the LWKXF centrifugal fan?
The LWKXF series is specifically engineered for commercial kitchen oil-fume exhaust and high-resistance duct systems, providing stable airflow and strong static pressure against grease and smoke buildup.
What are the advantages of the multi-vane centrifugal optimized impeller?
The multi-vane design converts motor power into stable airflow and pressure efficiently, reducing unnecessary airflow loss and preventing rapid grease accumulation on blades.
What casing options are available for the LWKXF series?
It offers A-Type Standard Casing for conventional ventilation layouts and B-Type Square Casing for project-specific equipment integration and compact installation spaces.
How does the thickened carbon steel casing protect the fan?
The heavy-gauge carbon steel housing features a robust spray-coated surface that offers excellent wear and corrosion resistance, ensuring continuous dependable operation in greasy and harsh environments.
Is the LWKXF series suitable for long or multi-section duct runs?
Yes. Optimized fan performance and high static pressure capability help maintain reliable airflow when duct resistance is high, making it ideal for long, multi-section, or high-rise ventilation systems.
What motor power ratings are offered in this series?
Motor power ranges from 0.37 kW up to 15 kW across comprehensive frame sizes from 2A to 6.3A to match diverse commercial exhaust loads.
