Lubricated Rotary Screw Air Compressors
A rotary screw air compressor is a positive displacement compression system that includes a pair of matching helical screws. An oil-flooded rotary screw compressor includes a lubricant that fills the gap between the rotors, which creates an air-tight hydraulic seal and transfers mechanical energy between the two rotors. The air moves through the threads as the screws rotate, and the meshing screws force the air through the compressor.

Oil Free Compressors
What is an Oil-Free Air Compressor?
Oil-free air compressors help manufacturers create products with high air quality throughout the manufacturing process. This equipment typically has no mechanical contact inside the compression chamber, or it uses an alternate material like water or Teflon coating to protect the internal mechanisms without depending on oil lubrication. Oil-free air compressors can provide air purity, environmental benefits and significant cost savings for manufacturers.
QOF 2-30 hp Oil-Free Scroll Compressors
Class Zero represents the best air quality possible. In critical environments, it is essential that the compressed air is 100% oil-free. Contamination by even the smallest quantities of oil can cause costly production down time and product spoilage, resulting in product recalls and loss of reputation. The new Quincy QOF 2-30 oil-free scroll compressors meet the Class Zero standard and also provide top class performance, premium efficiency and quality. Outstanding reliability, low maintenance and operating costs make oil-free compressors a sound investment.
WIS 20-75hp Oil-Free Water Injected Screw Compressors
WISAIR’s water injected screw offers the most innovative oil free technology and improved energy efficiency thanks to the superior cooling capability of water.

Multi-Stage Compressors
Reciprocating/piston compressors use a cylinder to force air into a chamber, where it is compressed. The simplest compressor designs feature a single cylinder/chamber arrangement. While straightforward, this setup is limited in its efficiency and capacity for delivering high volumes of pressurized air.
That’s where multi-stage compressors come in. By increasing the number of cylinder stages, these machines work more effectively and can handle more tools at once.
How Multi-stage Compressors Work
Multi-stage compressors feature a series of cylinders, each of a different diameter. Between each compression stage, the air passes through a heat exchanger, where it is cooled. Cooling the air reduces the amount of work necessary to compress it further.
In a two-stage compressor, air is then forced into an additional chamber where it is pressurized to the required extent. In a three-stage compressor, an additional cycle of compression and cooling occurs before this.
Benefits of Multi-stage Compression
Both single and multi-stage compressors have their benefits. The right one for your application will depend on a number of factors. Specific advantages of a three- or two-stage compressor design include:
- Improved efficiency. Two-stage compressors perform less work to compress air to a given pressure, which means your operating costs are lower.
- Better reliability. The intercooling stage of two-stage compression creates less chance of overheating, which in turn means more uptime and better productivity.
- Less moisture buildup. Cooler air has a lower moisture content. Moisture in compressed air can lead to equipment failure and premature wear. Using a two- or three-stage compressor can potentially save you from having to purchase a separate air dryer.
- Smaller footprint. For heavy-duty applications, multi-stage compressors deliver greater air pressure (PSI) at higher capacities (CFM) than single-stage machines of a comparable size.
- Few maintenance requirements. Thanks to smaller components and cooler temperatures, wearable components don’t wear out as quickly. As a result, recommended service intervals are longer.
Applications
Clearly there are benefits to selecting a multi-stage machine; however, their higher cost means they are not necessarily the right choice for every application. Generally speaking, single-stage compressors are best for light-duty, intermittent use applications, in which pressure requirements don’t exceed 100 PSIG. Two- or three-stage compressors, on the other hand, offer better value and reliability for continuous use applications, such as auto repair and manufacturing.

Natural Gas Compressors
A natural gas compressor increases the pressure of a gas by reducing its volume. The natural gas enters the cylinder through the intake valves, where it is compressed and forced out through discharge valves. A gas air compressor is one form of natural gas compressor that is used in a wide range of industrial applications where either high pressure or lower volumes of gas are required. Examples include:
- Petroleum refineries, natural gas processing plants and chemical plants: Used for the compression of intermediate and end-product gases
- Industrial manufacturing and building: Provides compressed air that powers various pneumatic tools and equipment
- Pipelines: Transporting natural gas from the production site to the end user
QRNG Reciprocating Gas Compressor
A reciprocating gas compressor uses crankshaft-driven pistons to provide compression. The thrust is provided by a positive displacement pump that moves the gas through the system and enhances the gas’s pressure and density. Benefits of reciprocating gas compressors include their ability to produce high power and high pressure compressed gas, as well as the absence of an oil carryover problem. Reciprocating compressors also generally require a lower initial investment than other compressor types.
