The Hasegawa Cover for Suction Chamber is a protective component used in Hasegawa compressors to enclose the suction chamber. The suction chamber is responsible for drawing in refrigerant gas into the compressor. This cover ensures that the chamber remains sealed, protecting it from contaminants and external damage. By maintaining a secure and efficient suction process, the cover contributes to the overall reliability and performance of the compressor, helping to extend its lifespan in refrigeration and HVAC systems.
