Названия сторонних брендов и моделей используются только для идентификации существующего оборудования и его габаритных данных. HEXNOVAS — независимый поставщик, не связанный с этими производителями и не получивший их одобрения. Compatibility requires verification of the original plate, gasket groove and operating duty.
