ACU-FLAP can and has been installed at combined sewer overflow (CSO) locations, sanitary sewer overflow (SSO) locations, holding tank overflows and pond overflows. Overloading of sewer systems and treatment plants is avoided, and energy costs for pumping systems and wastewater treatment are reduced. The ACU-FLAP also controls odours, as it is normally in the closed position.<\/p>\n<p>\n<\/div>\n<div class=\"kc-elm kc-css-873402\">\n\t<a class=\"kc_button\" href=\"\/en\/contactez-nous\/\" target=\"_self\" title=\"\" onclick=\"\">\n\t\tRequest your brochure\t<\/a>\n<\/div>\n<\/div><\/div><\/div><div class=\"kc-elm kc-css-66101 kc_row kc_row_inner\"><div class=\"kc-elm kc-css-657165 kc_col-sm-6 kc_column_inner kc_col-sm-6\"><div class=\"kc_wrapper kc-col-inner-container\"><div class=\"kc-elm kc-css-646028 kc_text_block\"><\/p>\n<p>\n-Up to 7 ft (2 m) headroom<\/p>\n<p>-Modular construction up to 13 ft (4 m) long<\/p>\n<p>-Rabat en \u00e9lastom\u00e8re<\/p>\n<p>-Opens with minimal water level rise<\/p>\n<p>-Airtight design for odor control<\/p>\n<p>-Low hydraulic resistance<\/p>\n<p>-Easy to adapt to existing installations<\/p>\n<p>-Stainless steel construction<\/p>\n<p>\n<\/div><\/div><\/div><div class=\"kc-elm kc-css-331896 kc_col-sm-6 kc_column_inner kc_col-sm-6\"><div class=\"kc_wrapper kc-col-inner-container\"><div class=\"kc-elm kc-css-941059 kc_shortcode kc_single_image\">\n\n        <img decoding=\"async\" src=\"https:\/\/grandeinc.com\/wp-content\/uploads\/2024\/06\/acu-flap-2.jpg\" class=\"\" alt=\"\" \/>    <\/div>\n<\/div><\/div><\/div><div class=\"kc-elm kc-css-495757 kc_row kc_row_inner\"><div class=\"kc-elm kc-css-870160 kc_col-sm-6 kc_column_inner kc_col-sm-6\"><div class=\"kc_wrapper kc-col-inner-container\"><div class=\"kc-elm kc-css-638150 kc_shortcode kc_single_image\">\n\n        <img decoding=\"async\" src=\"https:\/\/grandeinc.com\/wp-content\/uploads\/2024\/06\/acu-flap-3.jpg\" class=\"\" alt=\"\" \/>    <\/div>\n<\/div><\/div><div class=\"kc-elm kc-css-406789 kc_col-sm-6 kc_column_inner kc_col-sm-6\"><div class=\"kc_wrapper kc-col-inner-container\"><div class=\"kc-elm kc-css-307449 kc_text_block\"><\/p>\n<h2>Application scope<\/h2>\n<p>The ACU-FLAP control unit may vary from GAF-40-* to GAF-100-*. The GAF-40-* is designed to fit over a concrete opening measuring 16 inches (40 cm) high and up to a maximum width of 13 feet (4 m), and the GAF-100-* is designed to fit over a concrete opening measuring 40 inches (100 cm) high and up to a maximum width of 13 feet (4 m). ACU-FLAP model selection is based solely on the size of the concrete opening. Units are currently marked with an asterisk due to the wide variety of model options.<\/p>\n<p>\n<\/div><\/div><\/div><\/div><div class=\"kc-elm kc-css-201450 kc_row kc_row_inner\"><div class=\"kc-elm kc-css-249921 kc_col-sm-6 kc_column_inner kc_col-sm-6\"><div class=\"kc_wrapper kc-col-inner-container\"><div class=\"kc-elm kc-css-972563 kc_text_block\"><\/p>\n<h2>How it works<\/h2>\n<p>The ACU-FLAP control unit is an elastomer flap mounted on a rectangular concrete opening. In its resting position, the elastomer flap is bolted along the top edge of its stainless steel mounting frame, closing and sealing the opening. If the water level in the sewer or reservoir overflow rises, hydrostatic pressure against the ACU-FLAP control unit causes it to open, allowing water to flow over the weir. If the downstream water level rises, the ACU-FLAP is pressed against its stainless steel mounting frame so that no water can flow back into the sewage system, reservoir or pond. The ACU-FLAP's lightweight design makes it highly responsive to minimal changes in water level, while ensuring structural stability under average downstream water level conditions.<\/p>\n<p>The ACU-FLAP control unit features an integrated stainless steel frame for anchoring to the concrete structure. This flat, smooth sealing surface increases the flap's watertightness and avoids potential problems caused by openings and uneven concrete surfaces.<\/p>\n<p>The ACU-FLAP control unit can be fitted with a stainless steel plate for added rigidity and weight to improve odor control and adapt to higher return water conditions.<\/p>\n<p>\n<\/div><\/div><\/div><div class=\"kc-elm kc-css-75928 kc_col-sm-6 kc_column_inner kc_col-sm-6\"><div class=\"kc_wrapper kc-col-inner-container\"><div class=\"kc-elm kc-css-242976 kc_shortcode kc_single_image\">\n\n        <img decoding=\"async\" src=\"https:\/\/grandeinc.com\/wp-content\/uploads\/2024\/06\/acu-flap-4.jpg\" class=\"\" alt=\"\" \/>    <\/div>\n<div class=\"kc-elm kc-css-860175 kc_shortcode kc_single_image\">\n\n        <img decoding=\"async\" src=\"https:\/\/grandeinc.com\/wp-content\/uploads\/2024\/06\/acu-flap-5.jpg\" class=\"\" alt=\"\" \/>    <\/div>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/section><\/p>","protected":false},"excerpt":{"rendered":"","protected":false},"author":4,"featured_media":0,"parent":595,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-900","page","type-page","status-publish","hentry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v24.0 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>\u00c9L\u00c9MENT DE CONTR\u00d4LE ACU-FLAP - Grande Gestion des Eaux<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/grandeinc.com\/en\/produits\/backflow-prevention\/element-de-controle-acu-flap\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"\u00c9L\u00c9MENT DE CONTR\u00d4LE ACU-FLAP - Grande Gestion des Eaux\" \/>\n<meta property=\"og:description\" content=\"Le syst\u00e8me d&rsquo;\u00e9l\u00e9ments de contr\u00f4le ACU-FLAP est con\u00e7u pour pr\u00e9venir les inondations et les reflux caus\u00e9s par des niveaux d&rsquo;eau \u00e9lev\u00e9s en aval.
