Condition: new, Thanks to their modular design, the PROFI JET® series system filter units enable the bespoke planning and construction of extraction solutions for virtually any required air volume and practically every conceivable application. The proven system also impresses with outstanding noise protection due to its insulated wall panels and, when installed outdoors, minimizes heat loss. Eligible for BAFA funding under Module 4. Operation: The custom-designed extraction systems of the PROFI JET series are built on a robust steel frame. The frame is fully clad with insulated, double-walled, powder-coated steel sheet panels to ensure that all components—including fan, filter cleaning, and discharge elements—are protected from dirt and weather within the closed system enclosure. The clean-air side fans are installed at the top of the unit and draw in dust- and chip-laden air into the filter section. A generously proportioned pre-separation chamber ensures effective separation of coarse particles and chips. The subsequent filter bags or cartridges remove any remaining fine dust. The cleaned exhaust air is routed through a sound-insulated return air chamber either back into the building or discharged outside. Applications: - Extraction at multiple processing machines, workstations, or entire production areas - Spatial ventilation and extraction for enclosures and work cabins - Suitable for virtually all types of dust and chips - Also for dusts and applications with ATEX classification - Extraction especially in the wood, plastics, metal, welding, cutting, and recycling industries—as well as many others Advantages: - Custom, precise planning and implementation of your extraction system - Cost-effective and quick delivery due to modular design with standard components - Quiet and energy-saving operation thanks to insulated panels - Consistently high extraction performance due to integrated pre-separation chamber and AL-KO OPTI JET® filter cleaning system - Heating cost savings, as 100% recirculated air operation is possible in many cases - Minimal space requirements due to compact construction - Suitable for indoor and outdoor installation - Professional appearance thanks to powder-coated panels Gbodpjwwryqofx Aiveu - Available in ATEX-compliant versions - Comprehensive accessories and numerous options for individualized system configuration - Eligible for BAFA funding under Module 4

Condition: new, SAPI Powder Coating The Perfect Coating for Lasting Protection. Gbedpfxeun Sd Uj Aiveu Powder coating is a highly effective and widely used method for applying a protective and decorative surface to various types of substrates. It is a dry finishing process where a fine powder made of resins, pigments, and additives is applied to a substrate. The powder is electrostatically charged, allowing it to adhere evenly to the surface and form a uniform coating. To achieve optimal adhesion and durability, the substrate is thoroughly cleaned and prepared first. Oils, dirt, and other contaminants are removed to ensure a clean surface. This is crucial for ensuring that the powder bonds effectively to the substrate, creating a strong and long-lasting coating. Components of a Powder Coating System A typical powder coating system consists of several components and devices required for applying and curing the powder coating. Spray Booth and Spray Area The booth provides a clean environment for the application process and ensures an even distribution of the powder. 🎨 Powder Coating Gun A powder coating gun is used to apply the powder coating to the workpiece. 💨 Powder Feed System The powder feed system consists of a hopper or container where the powder coating material is stored. It typically includes devices like powder pumps, feed hoses, and powder sieves to transport the powder from storage to the spray gun. 🔄 Pre-treatment Equipment Pre-treatment systems are used to prepare the substrate before applying the powder coating. This can include processes like cleaning, degreasing, rinsing, and surface treatment to ensure proper adhesion and durability of the coating. 🧼 Curing Oven A curing oven is a crucial component of a powder coating system. It is used to heat the coated substrate to the correct temperature so the powder coating melts, flows, and hardens into a permanent surface. The oven usually consists of a conveyor system or racks to transport the coated parts through the oven chamber. 🔥 Exhaust System An exhaust system is installed to remove excess powder, fumes, or volatile compounds generated during the coating process. It helps maintain a clean and safe work environment for the personnel and prevents the accumulation of powder particles in the air. 🌬️ Looking for a Powder Coating Solution?
