Fan units - Import export

For forced cooling, Seifert electronic offers compact fan units in various performance classes. The variable fin spacing in the high-performance heat sinks ensures strong cooling during fan operation. In forced convection cooling, fans are required as separate sources of convection. To ensure optimal convection during fan operation, it is recommended to incorporate heat sink profiles. The fin spacing in heat sink profiles is particularly important, as increasing the surface area is key for forced cooling. To push this boundary further, we have continuously reduced the fin spacing in our profiles. Depending on the model, up to three fans per cooler are possible, which can optionally be equipped with pressure chambers for improved air guidance. Most heat sinks are already equipped with aerodynamically designed hollow fins. Additionally, air deflectors for air guidance are available for some heat sink profiles.

Compact filters are characterised by the fact that they essentially unite fan, filter element and discharge or dust collection facility in one. The capacity range of the compact filters extends up to 20,000 m³/h. Different systems and modes of operation are available for the individual assemblies, resulting in a large number of possible variants. This allows us to offer a large range of solutions for dedusting tasks. Based on our many years of experience, we select the filter media from those available on the market that are best suited for the most diverse types of dust and tasks. Filter hoses, filter bags, filter tubes and filter cartridges are used as filter elements. Cleaning takes place using compressed air impulse, low-pressure purge-air or shaking. Fans from own development and production enable us to design a highly efficient and precise layout. Discharge usually takes place directly into collecting containers, such as dustbins with snap fasteners, or into containers, big bags, or via discharge mechanisms into automatic disposal systems. Screw conveyors, drag conveyors, rotary systems, cellular wheel sluices, double-gate sluices and slidegate valves are available as discharge mechanisms. Intelligent control systems, piping elements, silencers and pre-coating devices for auxiliary dusts are standard items in the range. Naturally we also use our know-how to create needs-based custom solutions.

The filter housing is made of sturdy steel plate with a reinforcement of structural steel frame. Equipped with inlet and outlet openings for the dusty or filtered air. The inspection cap is used to control the automatic filter and has a flap for access to the built-in filter cartridges. These are made of folded polyester material having a filter area of each of 8 and 14 m². Provided with upper and lower reinforcing rings of plastics material for fastening in the holders. The dust drawer is equipped with wheels, allowing easy extraction during disposal of the dust. The centrifugal fan with a flanged electric motor and the fan / motor unit is built up in the filter housing - the motor is bolted with its flanges on the filter housing and surrounded by the sound enclosure.
