The materials used in the construction of your specified centrifugal fan are of major importance. They will often be determined by the working environment \u2013 or the quality of the air passing through the fan.<\/p>\n
Centrifugal fan materials and construction methods can differ, depending on which type of unit <\/span>is specified: forward curved, backward curved or radial. It is important to consider the fan\u2019s casing, motor and impeller \u2013 especially the latter because it plays such a crucial role in moving the air.<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_2,1_2″ _builder_version=”4.19.4″ _module_preset=”default” width_tablet=”90%” width_phone=”90%” width_last_edited=”on|tablet” custom_margin=”|auto|40px|auto||” locked=”off” global_colors_info=”{}”][et_pb_column type=”1_2″ _builder_version=”4.19.4″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.19.4″ _module_preset=”default” text_font_size=”20px” link_option_url=”https:\/\/fans-uk.aircontrolindustries.com\/” locked=”off” global_colors_info=”{}”]<\/p>\n FIND YOUR CENTRIFUGAL FAN<\/strong><\/p>\n [\/et_pb_text][et_pb_image src=”https:\/\/www.aircontrolindustries.com\/wp-content\/uploads\/2023\/02\/Fan-Selector-1.jpg” alt=”Screenshot of the ACI fan selector tool” title_text=”Fan Selector” url=”https:\/\/fans-uk.aircontrolindustries.com\/” align=”center” _builder_version=”4.19.4″ _module_preset=”default” width=”50%” module_alignment=”center” custom_margin=”||40px|||” locked=”off” global_colors_info=”{}”][\/et_pb_image][et_pb_button button_url=”https:\/\/fans-uk.aircontrolindustries.com\/” button_text=”Fan Selector Tool” button_alignment=”center” _builder_version=”4.19.4″ _module_preset=”default” locked=”off” global_colors_info=”{}”][\/et_pb_button][\/et_pb_column][et_pb_column type=”1_2″ _builder_version=”4.19.4″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.19.4″ _module_preset=”default” text_font_size=”20px” link_option_url=”https:\/\/www.youtube.com\/watch?v=bioXbuzq-VA” global_colors_info=”{}”]<\/p>\n USING THE FAN SELECTOR TOOL<\/strong><\/p>\n [\/et_pb_text][et_pb_image src=”https:\/\/www.aircontrolindustries.com\/wp-content\/uploads\/2023\/02\/Fan-Selector-Video-4.jpg” title_text=”Fan Selector Video” url=”https:\/\/www.youtube.com\/watch?v=bioXbuzq-VA” align=”center” _builder_version=”4.21.0″ _module_preset=”default” width=”40%” custom_margin=”||82px||false|false” box_shadow_style=”preset2″ global_colors_info=”{}”][\/et_pb_image][et_pb_button button_url=”https:\/\/www.youtube.com\/watch?v=bioXbuzq-VA” button_text=”Watch The Video” button_alignment=”center” _builder_version=”4.19.4″ _module_preset=”default” global_colors_info=”{}”][\/et_pb_button][\/et_pb_column][\/et_pb_row][et_pb_row custom_padding_last_edited=”on|tablet” _builder_version=”4.21.0″ _module_preset=”default” width=”100%” width_tablet=”90%” width_phone=”90%” width_last_edited=”on|tablet” module_alignment=”center” custom_margin=”25px|19px|25px|20px|false|false” custom_margin_tablet=”15px|40px||60px|false|false” custom_margin_phone=”15px|40px||60px|false|false” custom_margin_last_edited=”on|desktop” custom_padding=”0px|0px|0px|32px|false|false” custom_padding_tablet=”|||0px|false|false” custom_padding_phone=”|||0px|false|false” locked=”off” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.18.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.21.2″ _module_preset=”default” text_font_size=”30px” text_line_height=”1.1em” header_text_color=”#003366″ header_font_size=”25px” header_2_font_size=”25px” custom_margin=”0px||0px||false|false” custom_margin_tablet=”0px||30px||false|false” custom_margin_phone=”0px||0px||false|false” custom_margin_last_edited=”on|desktop” custom_padding=”20px||0px||false|false” custom_padding_tablet=”20px||||false|false” custom_padding_phone=”20px||||false|false” custom_padding_last_edited=”on|desktop” locked=”off” global_colors_info=”{}”]<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”3_5,2_5″ custom_padding_last_edited=”on|tablet” _builder_version=”4.19.4″ _module_preset=”default” width=”100%” width_tablet=”90%” width_phone=”90%” width_last_edited=”on|tablet” module_alignment=”center” custom_margin=”10px|19px|8px|20px|false|false” custom_margin_tablet=”15px|40px||60px|false|false” custom_margin_phone=”15px|40px||60px|false|false” custom_margin_last_edited=”on|desktop” custom_padding=”9px|0px|3px|32px|false|false” custom_padding_tablet=”|||0px|false|false” custom_padding_phone=”|||0px|false|false” global_colors_info=”{}”][et_pb_column type=”3_5″ _builder_version=”4.18.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.21.0″ _module_preset=”default” width=”90.1%” custom_padding=”|34px|||false|false” custom_padding_tablet=”|30px|||false|false” custom_padding_phone=”|0px|||false|false” custom_padding_last_edited=”on|phone” locked=”off” global_colors_info=”{}”]<\/p>\n Most fan casings tend to be cast from aluminium \u2013 regardless of which type the fan may be.

This compact but powerful fan is produced in large volumes for applications including fume cupboards and clean rooms. The VBL6\u2019s LM6 casing is finished in black powder coating for added protection.<\/span><\/p>\n However, aluminium has a low melting point, so stainless steel is recommended for more challenging industrial environments. In this instance, the casing must be fabricated (welded) rather than cast.<\/p>\n This is a more labour-intensive process than sand casting or gravity casting an aluminium casing. But opting for fabrication rather than casting makes it quicker and easier to add in custom features.<\/p>\n Grade 304 stainless steel is recommended for general applications where diecast aluminium is not suitable. (Grade 304 is the world\u2019s most popular type of stainless steel, not least because it\u2019s the one used for cutlery.) However, grade 316 would be needed for food processing<\/strong><\/span><\/a>, pharmaceutical<\/a> <\/strong><\/span>or petrochemical<\/strong><\/span><\/a> applications. And grade 316L offers superior corrosion resistance because it has a lower carbon content.<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_3,1_3,1_3″

constructed from diecast aluminium. Most housings are of the \u2018squirrel cage\u2019 type with fins to aid cooling.<\/p>\n Aluminium is usually the material of choice for motor housings for all the reasons outlined above. But cast iron is recommended for applications where robustness is key \u2013 especially in environments where there is a risk of explosions.<\/p>\n Cast iron is strong and durable. It has good mechanical strength and is resistant to wear and tear. However, it is much heavier than aluminium \u2013 and it is also vulnerable to corrosion. Applying a protective coating, such as paint or enamel, can prevent exposure of the cast iron to moisture and oxygen.<\/p>\n [\/et_pb_text][\/et_pb_column][et_pb_column type=”2_5″ _builder_version=”4.18.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_image src=”https:\/\/www.aircontrolindustries.com\/wp-content\/uploads\/2023\/05\/Fan-Motor-2.jpg” alt=”Fan with Cast Iron Motor” title_text=”Fan Motor” align=”center” _builder_version=”4.21.0″ _module_preset=”default” width=”85%” module_alignment=”center” custom_margin=”-7px||||false|false” custom_padding=”3px|||||” box_shadow_style=”preset1″ global_colors_info=”{}”][\/et_pb_image][\/et_pb_column][\/et_pb_row][et_pb_row custom_padding_last_edited=”on|tablet” _builder_version=”4.21.0″ _module_preset=”default” width=”100%” width_tablet=”90%” width_phone=”90%” width_last_edited=”on|tablet” module_alignment=”center” custom_margin=”25px|19px|25px|20px|false|false” custom_margin_tablet=”15px|40px||60px|false|false” custom_margin_phone=”15px|40px||60px|false|false” custom_margin_last_edited=”on|desktop” custom_padding=”0px|0px|0px|32px|false|false” custom_padding_tablet=”|||0px|false|false” custom_padding_phone=”|||0px|false|false” locked=”off” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.18.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.21.0″ _module_preset=”default” text_font_size=”30px” text_line_height=”1.1em” header_text_color=”#003366″ header_font_size=”25px” header_2_font_size=”25px” custom_margin=”0px||0px||false|false” custom_margin_tablet=”0px||30px||false|false” custom_margin_phone=”0px||0px||false|false” custom_margin_last_edited=”on|desktop” custom_padding=”20px||0px||false|false” custom_padding_tablet=”20px||||false|false” custom_padding_phone=”20px||||false|false” custom_padding_last_edited=”on|desktop” locked=”off” global_colors_info=”{}”]<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”3_5,2_5″ custom_padding_last_edited=”on|tablet” _builder_version=”4.19.4″ _module_preset=”default” width=”100%” width_tablet=”90%” width_phone=”90%” width_last_edited=”on|tablet” module_alignment=”center” custom_margin=”5px|19px|40px|20px|false|false” custom_margin_tablet=”15px|40px||60px|false|false” custom_margin_phone=”15px|40px||60px|false|false” custom_margin_last_edited=”on|desktop” custom_padding=”0px|0px|3px|32px|false|false” custom_padding_tablet=”|||0px|false|false” custom_padding_phone=”|||0px|false|false” global_colors_info=”{}”][et_pb_column type=”3_5″ _builder_version=”4.18.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.21.0″ _module_preset=”default” width=”90.1%” custom_margin=”||15px||false|false” custom_padding=”13px|35px|||false|false” custom_padding_tablet=”|0px|||false|false” custom_padding_phone=”|0px|||false|false” custom_padding_last_edited=”on|phone” locked=”off” global_colors_info=”{}”]<\/p>\n Impellers comprise a back plate, shroud (front) plate and blades.<\/p>\n Forward-curved centrifugal fan impellers<\/strong> are manufactured from mild steel that is protected with a layer of zinc to help prevent corrosion. That zinc layer can be applied by galvanisation (dipping in molten zinc) or by plating (using electrolysis).<\/p>\n \u00a0Backward-curved and radial centrifugal fans<\/strong> have larger, weightier impellers than their forward-curved counterparts. The impeller blades of backward-curved and radial fans are bigger (and spaced further apart) than those in the \u2018hamster wheel\u2019 impellers of forward-curved fans.<\/p>\n This means that backward-curved and radial impellers are usually manufactured from thicker, heavier steel that can be wet painted if required. (Blade size and spacing is not the issue it can be with forward-curved impellers).<\/p>\n These heavier impellers are almost always handmade, whereas the forward-curved variety are usually machine manufactured because the steel is thinner and more workable. However, forward-curved impellers can be custom-made by hand if required.<\/p>\n [\/et_pb_text][\/et_pb_column][et_pb_column type=”2_5″ _builder_version=”4.18.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_image src=”https:\/\/www.aircontrolindustries.com\/wp-content\/uploads\/2023\/05\/Impellers-4.jpg” alt=”Forward and Backward curved impellers” title_text=”Impellers” align=”center” _builder_version=”4.21.0″ _module_preset=”default” width=”85%” module_alignment=”center” custom_margin=”44px||||false|false” custom_margin_tablet=”44px||||false|false” custom_margin_phone=”0px||||false|false” custom_margin_last_edited=”on|phone” box_shadow_style=”preset1″ locked=”off” global_colors_info=”{}”][\/et_pb_image][\/et_pb_column][\/et_pb_row][et_pb_row custom_padding_last_edited=”on|tablet” _builder_version=”4.19.4″ _module_preset=”default” width=”100%” width_tablet=”90%” width_phone=”90%” width_last_edited=”on|tablet” module_alignment=”center” custom_margin=”25px|19px|41px|20px|false|false” custom_margin_tablet=”15px|40px||60px|false|false” custom_margin_phone=”15px|40px||60px|false|false” custom_margin_last_edited=”on|desktop” custom_padding=”0px|0px|0px|32px|false|false” custom_padding_tablet=”|||0px|false|false” custom_padding_phone=”|||0px|false|false” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.18.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.21.2″ _module_preset=”default” text_font_size=”30px” text_line_height=”1.1em” header_text_color=”#003366″ header_font_size=”25px” header_2_font_size=”25px” custom_margin=”0px||45px||false|false” custom_margin_tablet=”0px||30px||false|false” custom_margin_phone=”0px||30px||false|false” custom_margin_last_edited=”on|desktop” custom_padding=”20px||||false|false” custom_padding_tablet=”20px||||false|false” custom_padding_phone=”20px||||false|false” custom_padding_last_edited=”on|desktop” locked=”off” global_colors_info=”{}”]<\/p>\n [\/et_pb_text][et_pb_text _builder_version=”4.21.0″ _module_preset=”default” custom_margin=”-15px||||false|false” custom_padding=”0px|71px|0px||false|false” custom_padding_tablet=”|0px|||false|false” custom_padding_phone=”|0px|||false|false” custom_padding_last_edited=”on|tablet” locked=”off” global_colors_info=”{}”]<\/p>\n Contact ACI\u2019s fan engineers for expert guidance on the best type of fan for your application.
