The exhaust ducts convey process exhaust air polluted by chemicals that can contain, for example, sulphuric, hydrochloric and nitric acids, sodium hydroxide or ammonia. HALAR is a material which can be powder coated and stems from the Teflon family. Compared to most other mediums it is durable, lasting and reliable. We can professionally design, engineer, manufacture and coat any standard shape, round or rectangular, for the air technology sector. Standard procedure for exterior surfaces is full-surface pickling.
A true LBF strength: finding and optimising technical solutions with our customers. Together with our customer’s ideas and our network of experience, we design products, provide services and complete projects. LBF can come aboard at any stage during a project – whether the solution is almost complete or if it is still unclear exactly what product is needed. Design sketches, brainstorming, sample productions, as well as taking measurements and testing all lead to finding a solution.
Fans are used for air extraction in exhaust air systems. This generates noise. Consequently, silencers are needed in the ducts. We offer rectangular Halar-coated silencers with integrated plastic splitters. The mineral wool is sealed in foil and placed in the sections of the splitter. The splitters are secured with bolted locking strips and can be easily removed in the direction of the air flow.
FM approval is required for the components, specifically for exhaust air systems, used in microchip facilities worldwide. As of 2001 LBF holds FM approval and is listed as a licensed supplier. The basis of which is a rigorous fire test at the American FM institute – wherein pipes and ducts are tested and certified for fire resistance and smoke emissions. In order to maintain FM approved status FM audits take place twice a year during production to confirm compliancy to manufacturing standards.
Pressure and leakage tests are used to assess the completed components and are considered a part of the quality inspection. Tanks, vessels and pipe systems can all be tested. These can be customer specified tests or legally required inspections, such as the final inspection and pressure test for pressure vessels. In addition to the stability, the tightness of the weld seams and the flange connectors is verified. This can be done at the factory for pre-assembled components, or on site for complete systems.
Freestanding exhaust air tower consisting of load-bearing rectangular collector ducts with side connecting ports, inspection openings, and above that a duct silencer and an outlet tube. The exhaust air tower was placed behind a filter system and blows the cleaned exhaust air straight up and out at a minimum speed and a requested distance from the structure, thereby quickly mixing the exhaust air with the ambient air.
