Oilless Compressor

Scroll Compressor

Compressed air from oilless compressors is used in numerous industries where pure air is essential for the end-product and the production process. These uses include food and beverage processing, pharmaceutical manufacturing and packaging, chemical and petrochemical processing, the medical sector, powering dental instruments, textile manufacturing and more. Compressed air is only suitable for some industries when it is pure.

Why Choose an Oilless Compressor?

When the compression process is exposed to oil, it becomes progressively difficult to keep the air pure, increasing the cost to the company. Many companies have turned to oil-free or oilless compressor systems because they offer cost savings. Besides the purity and environmental benefits, an oilless air compressor system will reduce your overall ownership costs. If you’re in an industry that demands air purity at 100% clean levels, then a compressor that doesn’t rely on internal oil is your best bet.

Oilless compressors are a more thoughtful choice and require careful consideration for your operations. The fundamentals of how oilless air compressors do their work means you will be looking at lower costs, a better footprint and 100% oil free air.

Types of Oilless Compressors

Powerex manufactures several types of oilless compressor systems: an open oilless scroll compressor, an enclosed oilless scroll compressor, and an oilless reciprocating piston compressor. Powerex was the first company to package NFPA 99 compliant oilless compressor systems. Today, Powerex designs and manufactures a complete line of NFPA 99 compliant oilless compressor systems. Along with manufacturing oilless compressors, they build many of their compressor major components, such as UL control panels, desiccant dryers, dew point monitors and internally lined air receivers in-house.

Scroll Oilless Compressor

Powerex scroll technology is an advanced air compression system which includes one mobile and one stationary spiral element that work together to bring air into the chamber for compression. This causes the air or gas to be trapped between the two spiral elements at the suction side and then transporting it to the center of the spiral, compressing the air or gas to be cooled. Because one element is stationary and the other moves in eccentric circles, there is little friction.or wear on the system. Scroll oilless compressors also work smoother, with a different sound from other compressors.

Enclosed Oilless Scroll Compressor Systems

Powerex's innovative enclosed scroll technology is completely oilless, extremely quiet, energy efficient, and requires little maintenance. The compressor’s sound enclosure cabinet reduces noise levels even further, allowing the to be installed right at the point of use. The small footprint also maximizes available floor space. The rotary design has few moving parts which makes it reliable and easier to maintain. The self-lubricating tip seals, and absence of a gearbox makes the pump truly 100% oil free.

As the leaders in enclosed scroll pump technology, Powerex’s latest enclosed scroll compressor systems offer several innovative features and benefits:

  • Oilless Scroll Technology
  • No Exhaust or Intake Valves
  • Whisper Quiet Enclosure
  • Pressure Gauge
  • Internal Air Receiver
  • Very Low noise level
  • Very low vibration
  • Low maintenance cost
  • 10-20 HP models are UL/CSA Certified

The Powerex Enclosed Scroll Compressor main bearings are housed in durable cast iron instead of aluminum which prevents fretting and premature failure of the bearings. Their pumps can be operated at 100% duty with assurance. The patented bearing re-grease feature also allows scheduled maintenance from the front side of the pump. It also has a patented tip seal design which yields the highest flow rates and longevity of any other dry scroll compressor on the market. The Powerex Enclosed Scroll Compressor improved efficiency and cooling results in lower operating temperatures.

Each system is packaged in a rigid steel frame with powder coated panels and lined with sound deadening insulation. The low noise levels are unmatched in the industry and allow the compressor to be installed right at the point of use. Our small footprint maximizes your floor space.

Reciprocating Oilless Compressor

The Powerex oilless tank mounted reciprocating compressor system is designed to provide clean, dry air for industrial applications where the quality of the compressed air is essential (dryer option is required for the dry air application). Starter control panel and dryer options are available to modify the system for any particular application.

The Powerex simplex and duplex reciprocating piston tank mounted systems are perfect for any application where clean dry air is essential. Examples of applications include manufacturing, instrumentation, pharmaceutical production, and in laboratories. Starter control panel and dryer options are available to modify the system for a numerous applications.

As the leaders in reciprocating piston technology, their latest reciprocating oilless compressor design offers several innovative features and benefits:

  • Low annual maintenance cost
  • Easy installation
  • Low operating temperatures
  • UL listed controls
  • Low noise
  • 462 (L) (2) Certified

The self-lubricating composite piston technology - standard on their reciprocating compressors, increases ring life, reduces temperature, and provides reliability for years to come. The dual cooling pistons decrease operating temperatures and the corrosion resistant components and coatings prolong ring and valve life.
