FAQ
Q1: What is a vibration eliminator in HVAC?
A: A vibration eliminator absorbs mechanical and dynamic vibrations from compressors, preventing copper tube fatigue and refrigerant leakage in HVAC systems.
Q2: How does a vibration absorber work?
A: It uses a stainless steel braided hose to flex and absorb vibration energy, isolating compressor movement from the piping network.
Q3: What is the difference between a vibration eliminator and isolator?
A: An eliminator is installed directly in refrigerant lines, while an isolator typically supports the compressor base. Both reduce vibration and noise.
Q4: Can KAK vibration eliminators be used for refrigeration?
A: Yes, they are ideal for air conditioning, heat pumps, and commercial refrigeration systems using R22, R410A, R32, or R134a refrigerants.
Q5: What materials are used in KAK eliminators?
A: Each unit features a stainless steel braided hose and seamless copper ODF tube ends for corrosion resistance and strong brazed sealing.
