The 48-DM filter cores are specifically designed for use in DM filters and provide an effective solution for improving the efficiency of heating systems. These filter cores consist of a solid insert made of 100% molecular sieve, suitable for use in HFC systems. They are compatible with various refrigerants, including R 134a, R 404a, and R 407C, and can also be used with additives in polyol ester oil. Weighing 565 grams each, these radiator boosters are a practical addition for heating systems that require reliable and efficient performance. The filter cores help optimize heating performance and are an essential accessory for the maintenance and operation of radiators. Using these filter cores can help extend the lifespan of heating systems and reduce their operating costs.
