Axial pressurisation fans are used for pressurising stairwells, lift shafts and similar areas, and are also an effective solution for high-airflow ducted projects. The special inclined housing design provides maximum airflow with minimum noise.<\/p>\n

Applications:<\/strong> Production areas, warehouses, logistics centres, public buildings, commercial buildings, residences and car parks.<\/p>\n

For transformers:<\/strong> Options specially designed for transformer cooling are available. The motors are developed specifically for axial fans and provide high energy savings.<\/p>\n","protected":false},"featured_media":9420,"template":"","meta":{"pagelayer_contact_templates":[],"_pagelayer_content":""},"product_cat":[253],"product_tag":[],"class_list":["post-9419","product","type-product","status-publish","has-post-thumbnail","product_cat-axial-fans","first","instock","shipping-taxable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/nvsair.com\/eng\/wp-json\/wp\/v2\/product\/9419","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/nvsair.com\/eng\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/nvsair.com\/eng\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/nvsair.com\/eng\/wp-json\/wp\/v2\/media\/9420"}],"wp:attachment":[{"href":"https:\/\/nvsair.com\/eng\/wp-json\/wp\/v2\/media?parent=9419"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/nvsair.com\/eng\/wp-json\/wp\/v2\/product_cat?post=9419"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/nvsair.com\/eng\/wp-json\/wp\/v2\/product_tag?post=9419"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
