Arcade machines require robust moisture protection to prevent electrical damage and component failure. The five most common protection methods include comprehensive cabinet sealing using rubber gaskets and silicone around doors and joints to block ambient humidity. Conformal coating represents another critical defense, where a thin protective polymer film is applied to printed circuit boards, creating a moisture-resistant barrier without affecting electrical functionality. Proper ventilation systems with filtered fans maintain air circulation, preventing stagnant humid air from accumulating inside the cabinet. Many operators utilize desiccant packs or moisture-absorbing materials strategically placed within the cabinet to actively reduce humidity levels. Finally, regular preventive maintenance including visual inspections for condensation, cleaning of ventilation filters, and monitoring environmental conditions completes an effective moisture protection strategy. These combined approaches help preserve the electronic components and mechanical systems that power classic and modern arcade cabinets, significantly extending their operational lifespan in various environmental conditions from humid arcades to home game rooms.
