* Model with backward curved blades. Sound pressure level measured at 3 m. M: single-phase, T: three-phase; 2K: 2-pole, 4K: 4-pole motor.<\/p>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"

The fan housing is made of electrostatic powder-coated cold-rolled steel sheet. Single-inlet radial fan with forward-curved blades; the impeller is made of corrosion-resistant, high-quality galvanised steel with an aerodynamic design for uniform airflow. As the motor is outside the airflow, higher air transfer is achieved. Thanks to its dense blade structure and efficient asynchronous motor, it produces high airflow and pressure for its size, runs quietly and requires little maintenance. The OBR 200M-2K* model has a cast aluminium impeller with widely spaced backward-curved blades.<\/p>\n

Applications:<\/strong> Used for ventilation of greenhouses, factories, warehouses, paint shops, shopping centres and workshops; also preferred by machine manufacturers for plastics and packaging machinery. Its compact size is an advantage where space is limited.<\/p>\n

Speed control:<\/strong> Speed can be adjusted with a linear voltage regulator on single-phase models and a frequency inverter on three-phase models (optional).<\/p>\n","protected":false},"featured_media":9440,"template":"","meta":{"pagelayer_contact_templates":[],"_pagelayer_content":""},"product_cat":[15],"product_tag":[],"class_list":["post-9439","product","type-product","status-publish","has-post-thumbnail","product_cat-centrifugal-fans2","first","instock","shipping-taxable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/nvsair.com\/eng\/wp-json\/wp\/v2\/product\/9439","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\/9440"}],"wp:attachment":[{"href":"https:\/\/nvsair.com\/eng\/wp-json\/wp\/v2\/media?parent=9439"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/nvsair.com\/eng\/wp-json\/wp\/v2\/product_cat?post=9439"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/nvsair.com\/eng\/wp-json\/wp\/v2\/product_tag?post=9439"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
