construction and installation of ventilation in the workshop quickly<\/span><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"vertical-align: inherit;\">Normally, it will only take 1 month to install a ventilation system for a 10,000m2 factory. Fast construction time will save you a lot of time and labor costs. Each unit of construction and installation of factory ventilation systems will have different working processes. However, there are basically the following main steps.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Step_1_Receive_information_from_customers\"><\/span><strong><span style=\"vertical-align: inherit;\">Step 1: Receive information from customers<\/span><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"vertical-align: inherit;\">Customers with installation needs request services, costs, and desired type of ventilation. After that, the receiving unit will conduct a factory survey and record the actual characteristics of the project.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Step_2_Make_a_drawing_of_factory_ventilation_give_a_quote\"><\/span><strong><span style=\"vertical-align: inherit;\">Step 2: Make a drawing of factory ventilation, give a quote<\/span><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"vertical-align: inherit;\">Based on the actual information about the surveyed works, the construction unit will sketch, build the installation design and arrange the ventilation system.

The drawing shows the most intuitive image of the factory and ventilation system after completion, helping business owners easily visualize and evaluate. After the customer agrees with the design, the two parties will sign a service contract.<\/span><\/p>\n<p><span style=\"vertical-align: inherit;\">Construction and installation of ventilation system: The construction unit will arrange and install all kinds of suction and ventilation equipment as shown in the design drawings. Installing an industrial factory ventilation fan is an extremely important step, affecting the ventilation and cooling efficiency of the system.<\/span><\/p>\n<p><span style=\"vertical-align: inherit;\">Measurement and adjustment for project acceptance: After the ventilation system is installed, the project staff will measure and calibrate to ensure the details are accurate and of good quality. best.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Step_4_Acceptance_of_the_project\"><\/span><strong><span style=\"vertical-align: inherit;\">Step 4: Acceptance of the project<\/span><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"vertical-align: inherit;\">The project has completed the installation and commissioning process, the construction unit will hand over it to the customer for acceptance.<\/span><\/p>\n<p><span style=\"vertical-align: inherit;\">Warranty after the project: The construction unit continues to monitor and support to solve problems about the ventilation system after it has been put into use.<\/span><\/p>\n<p><span style=\"vertical-align: inherit;\">Contact us today for a free consultation and answer at:<\/span><\/p>\n<div dir=\"auto\">\n<div dir=\"auto\">\n<div dir=\"auto\">\n<h2 dir=\"auto\"><span class=\"ez-toc-section\" id=\"Contact_information_P69_-_M_E_Contractor\"><\/span><span id=\"Thong_tin_lien_he_P69_-_Nha_Thau_Co_Dien_M_E\" class=\"ez-toc-section\"><\/span><span id=\"Thong_tin_lien_he_P69_-_Nha_Thau_Co_Dien_M_E\" class=\"ez-toc-section\"><\/span><span id=\"Thong_tin_lien_he_P69_-_Nha_Thau_Co_Dien_M_E\" class=\"ez-toc-section\"><\/span><span id=\"Thong_tin_lien_he_P69_-_Nha_Thau_Co_Dien_M_E\" class=\"ez-toc-section\"><\/span><span id=\"Thong_tin_lien_he_P69_-_Nha_Thau_Co_Dien_M_E\" class=\"ez-toc-section\"><\/span><span id=\"Thong_tin_lien_he_P69_-_Nha_Thau_Co_Dien_M_E\" class=\"ez-toc-section\"><\/span><strong><span style=\"vertical-align: inherit;\">Contact information P69 \u2013 M&amp;E Contractor<\/span><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<div dir=\"auto\">\n<div dir=\"auto\">\n<div dir=\"auto\">\n<p><span style=\"vertical-align: inherit;\">Address: No. 6\/165C Xuan Thuy, Cau Giay District, Hanoi<\/span><\/p>\n<p><span style=\"vertical-align: inherit;\">Website: https:\/\/p69.com.vn\/<\/span><\/p>\n<p><span style=\"vertical-align: inherit;\">Hotline: 02422121212 \u2013 0965937799<\/span><\/p>\n<p><span style=\"vertical-align: inherit;\">Email: kd@cokhip69.com.vn<\/span><\/p>\n<p><span style=\"vertical-align: inherit;\">Facebook:\u00a0 <\/span><a href=\"https:\/\/www.facebook.com\/p69nhathaucodien\" target=\"_blank\" rel=\"nofollow noopener\"><span style=\"vertical-align: inherit;\">https:\/\/www.facebook.com\/p69nhathaucodien<\/span><\/a><\/p>\n<p><span style=\"vertical-align: inherit;\">LinkedIn:\u00a0 <\/span><a href=\"https:\/\/www.linkedin.com\/in\/congtyp69\/\" target=\"_blank\" rel=\"nofollow noopener\"><span style=\"vertical-align: inherit;\">https:\/\/www.linkedin.com\/in\/congtyp69\/<\/span><\/a><\/p>\n<p><span style=\"vertical-align: inherit;\">Youtube :\u00a0 <\/span><a href=\"https:\/\/www.youtube.com\/channel\/UCOUwCnE5iGj8iqe_ZIUM7oA\" target=\"_blank\" rel=\"nofollow noopener\"><span style=\"vertical-align: inherit;\">https:\/\/www.youtube.com\/channel\/UCOUwCnE5iGj8iqe_ZIUM7oA<\/span><\/a><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<p><\/p>\n\n\n<div class=\"kk-star-ratings kksr-auto kksr-align-left kksr-valign-bottom\"\n    data-payload='{&quot;align&quot;:&quot;left&quot;,&quot;id&quot;:&quot;3515&quot;,&quot;slug&quot;:&quot;default&quot;,&quot;valign&quot;:&quot;bottom&quot;,&quot;ignore&quot;:&quot;&quot;,&quot;reference&quot;:&quot;auto&quot;,&quot;class&quot;:&quot;&quot;,&quot;count&quot;:&quot;1&quot;,&quot;legendonly&quot;:&quot;&quot;,&quot;readonly&quot;:&quot;&quot;,&quot;score&quot;:&quot;5&quot;,&quot;starsonly&quot;:&quot;&quot;,&quot;best&quot;:&quot;5&quot;,&quot;gap&quot;:&quot;5&quot;,&quot;greet&quot;:&quot;Rate this post&quot;,&quot;legend&quot;:&quot;5\\\/5 - (1 vote)&quot;,&quot;size&quot;:&quot;24&quot;,&quot;width&quot;:&quot;142.5&quot;,&quot;_legend&quot;:&quot;{score}\\\/{best} - ({count} {votes})&quot;,&quot;font_factor&quot;:&quot;1.25&quot;}'>\n            \n<div class=\"kksr-stars\">\n    \n<div class=\"kksr-stars-inactive\">\n            <div class=\"kksr-star\" data-star=\"1\" style=\"padding-right: 5px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px;
