Panasonic Rotary AC Compressors Fact Sheet

Panasonic is one of the leading rotary and residential AC compressor manufacturers, their products are highly regarded for their quality and effectiveness. Panasonic rotary compressors are compact, lightweight and utilize the most cutting edge technology, making them highly efficient and reliable.

In this FAQ we cover some of the most common questions we receive from our customers. If you want to know something that is not covered here please contact us and we will be happy to answer.

How does a Panasonic Rotary compressor work?

Panasonic AC 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 do Panasonic Rotary compressors support?

They are found in air conditioning products featuring the very latest technology and offering the highest efficiency on the market today. Panasonic AC compressors are engineered specifically for this SEER efficiency requirement. Combined with the inherently simply design of the rotary, this results in a high desirable and impressively economical solution.

What makes a Panasonic Rotary compressor so quiet?

The structure the 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, the design optimises efficiency and minimises noise.

What maintenance do they require?

Panasonic Rotary Compressors require little to no maintenance. They are built to last and are highly durable, designed to work non-stop. However, there are a few things that can be done to extend the life of the compressor.

Replacing the HVAC systems filters will help to ensure that all equipment will continue to run without issues and checking parts for wear and tear will help prolong the compressors life. It is also important to be sure that the compressor is lubricated. The lubricants are essential in maintaining the function of the compressor.

What is their duty cycle?

Panasonic Rotary Compressors can function at a 100 percent duty cycle.

How long will Panasonic Rotary Air Compressors last?

Panasonic Rotary Compressors will last about 100,000 hours before needing a replacement or rebuild. A Physical Vapor Deposition (PVD) coating on the vane, along with enhanced steel materials, significantly reduces wear and increases durability.
