FAQ
How does a Panasonic Rotary compressor work?
R2 compressors are rolling piston rotary compressors. The heart of the rotary 
compressor is the cylinder which houses the piston and the vane. The vane 
maintains constant contact with the piston as the piston rolls along the inside 
wall of the cylinder. As the piston rotates, gas is compressed into an 
increasingly smaller area until the discharge pressure is reached, releasing gas 
into the shell chamber. At the same time, more gas comes in through the 
suction port, enabling a continuous process of suction and discharge.
The simple design and symmetry of the cylinder components, combined with a 
special coating and premium materials, provide a highly durable and reliable 
product, rotation after rotation.
What SEER range does the Panasonic Rotary compressor support?
R2 compressors are found in air conditioning products featuring the very latest 
technology and offering the highest efficiency on the market today. Our R2 
compressors are engineered specifically for this SEER efficiency requirement. 
Combined with the inherently simple design of the rotary, this results in a high 
desirable and impressively economical solution. 
What makes Panasonic Rotary compressor so reliable?
Changes to the construction and material of internal components enables the 
R2 compressor to reliably operate with an above average maximum discharge 
pressure. A Physical Vapor Deposition (PVD) coating on the vane, along with 
enhanced steel materials, significantly reduces wear and increases durability.
What makes a Panasonic Rotary compressor so quiet?
The structure of the R2 compressor mechanism has been redesigned to 
increase stability and reduce vibration. Specifically, the compressor has an 
upper cylinder discharge, an enhanced fixed upper bearing, and reduced 
friction in the cylinder parts. The lower discharge and muffler in the dual 
piston compressors also enables lower noise levels. As a result, this new 
design optimises efficiency and minimises noise.
How do R2 rotary compressors compare to scroll and reciprocating 
compressors?
R2 rotary compressors are very similar to some scroll compressors in overall 
performance, including efficiency and reliability. The simple and symmetrical 
key components contribute to the R2 compressor’s reliability, light weight, 
compact size, and economical applied cost, without sacrificing the key 
performance requirements of high efficiency and low noise levels.
Which refrigerants can be used with Panasonic Rotary compressor?
Panasonic has R2 Rotary Compressors available for R410A applications.
