The REYM-102P model is an upgraded version of the REYM-101P device and belongs to the category of professional equipment that allows working with two types of powdered materials, saving time required for powder replacement. This model is based on a new electronic control board, ensuring maximum stability and operational safety. Additionally, the REYM-102P metallization device is equipped with a new powder feeder. During the improvement and modification of the feeder's design, special attention was paid to upgrading the mechanism, which guarantees stable powder feeding. The professional REYM-102P model includes a reducer with a pressure gauge, designed for monitoring and precise regulation of compressed air within the range of 0.5 to 0.9 MPa, while a moisture separator prepares the compressed air for operation. The REYM-102P metallization device is equipped with a new powder feeder. In the course of upgrading and modifying the feeder mechanism, the main focus was on enhancing its functionality to ensure stable powder feeding. The professional gas-dynamic metal spraying device REYM-102 features a high-power spraying module, allowing the application of nickel powder mixtures. The control panel with indicator functions enables checking the device's readiness for operation, proper system pressure, and stable power supply. The REYM-102P model is not equipped with a reducer or moisture separator. When connecting the device to a compressor, ensure that the reducer with a moisture separator used provides a compressed air throughput of 0.45 m³/min.
