Indeed, rather than to use all the pressure, even if not needed, through a strangulation device, it will be more profitable to regulate the speed to reach the operational flow-pressure point in order to save an important energy.<\/p>\n<p>A calculation can be made in order to evaluate the depreciation period time for the cost of a variable speed drive.<\/p>\n<p><a href=\"https:\/\/www.airvision.be\/\/wp-content\/uploads\/AIR-VISION-Regulation-of-the-fan-working-point-with-a-variable-speed-drive.pdf\">Regulation of the fan working with a variable speed drive<\/a><\/p>\n","protected":false},"template":"","class_list":["post-486","faq","type-faq","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/www.airvision.be\/en\/wp-json\/wp\/v2\/faq\/486","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.airvision.be\/en\/wp-json\/wp\/v2\/faq"}],"about":[{"href":"https:\/\/www.airvision.be\/en\/wp-json\/wp\/v2\/types\/faq"}],"wp:attachment":[{"href":"https:\/\/www.airvision.be\/en\/wp-json\/wp\/v2\/media?parent=486"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
