An air blower is a device which uses a rotating impeller in a housing to draw in air, pressurise it then expel it in a defined direction to achieve a desired effect. The relationship between impeller type, blade size\/design, housing size\/design and supply power is crucial to ensure that the right air volume is being discharged at the correct pressure for a given application \u2013 and without wasting energy.<\/p>\n

There are various types of air blowers \u2013 find out more here<\/a><\/span><\/strong> \u2013 but essentially, they fall into two main types, depending on the design of their impeller and housing and how they move the air:<\/p>\n Some 99% of the air blowers that we manufacture and\/or supply feature centrifugal impellers. This is because the combination of volume\/pressure output from centrifugal fans is much more useful in a wider range of applications than axial types.<\/p>\n

Some impellers \u2013 and therefore their housings \u2013 can be very large indeed; so big that you can climb inside one. Our largest air blower<\/a><\/strong><\/span> is around 7ft x 7ft x 5ft (2.1m x 2.1m x 1.5m) in the EV-BPR range, though we also manufacture air blowers as small as a human fist (the VBM3<\/a><\/strong><\/span>).<\/p>\n [\/et_pb_text][et_pb_image src=”https:\/\/www.aircontrolindustries.com\/wp-content\/uploads\/2023\/01\/Large-and-Small-Fans-1.jpg” alt=”Two images showing how industrial can be very large or small” title_text=”Large Industrial Fan vs Small cabinet size fan” url=”https:\/\/www.aircontrolindustries.com\/us\/industrial-fans\/” _builder_version=”4.21.2″ _module_preset=”default” width=”70%” module_alignment=”center” custom_margin=”41px||35px|||” box_shadow_style=”preset2″ global_colors_info=”{}”][\/et_pb_image][et_pb_text _builder_version=”4.23.1″ _module_preset=”default” custom_margin=”|0px|||false|false” custom_padding=”|30px|||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 But the biggest mistake that some users make is something else entirely.

different ways:<\/p>\n <\/p>\n [\/et_pb_text][et_pb_button button_url=”https:\/\/www.aircontrolindustries.com\/contact\/” button_text=”Talk to us for more information” _builder_version=”4.19.4″
