The Hasegawa Cover for Shaft Seal is a protective component used in Hasegawa compressors to enclose and safeguard the shaft seal. The shaft seal prevents refrigerant leakage around the rotating shaft, ensuring that the compressor operates efficiently and without loss of refrigerant. This cover protects the seal from external contaminants and damage, helping maintain the integrity of the sealing system. It plays a crucial role in ensuring the compressor’s reliable performance and extending its service life in refrigeration and HVAC applications.
