The Rotary Scroll compressor is a popular style compressor and is used primarily for air conditioning refrigerant systems. Recently, since it is very efficient, quiet and reliable it has been adopted by industrial air compressor manufacturer’s to expand their product offering for their smaller, high-efficiency product line.
They operate on the principle of two intermeshing spirals or scrolls with one being stationary while the other rotates or orbits in relation to it. They are mounted with 180° phase displacement between them which forms air pockets having different volumes. Air enters through the inlet port located in the rotating/orbiting scroll which fills the chambers and as is moved along and compressed along the scroll surfaces.
Some of the key advantages of a Rotary Scroll Compressor are:
- Pulsation free delivery due to the continuous flow from the suction port to the outlet port.
- No metal to metal contact thereby eliminating the need for lubrication
- Low noise levels
- Fewer moving parts means less maintenance
- Energy Efficient
- Air cooled
The largest disadvantage is they are available in a limited range of sizes and the largest SCFM outputs are around 100 SCFM.
This is exactly where EXAIR shines, we offer 15 product lines of highly efficient & quiet point of use compressed air products and accessories to compliment their limited output volume of air. All EXAIR products are designed to use compressed air efficiently and quietly, many of which reduce the demand on your air compressor which will help control utility costs and possibly delay the need to add additional compressed air capacity.
As an example, EXAIR’s Super Air Knives deliver exceptional efficiency by entraining ambient air at ratios of up to 40:1 and they are able to deliver an even laminar flow of air ranging from a gentle breeze to exceptionally hard-hitting force.
EXAIR’s Super Air Amplifiers are able to entrain ambient air at ratio’s up to 25:1. The model 120024 – 4″ Super Air Amplifier developes output volumes up to 2,190 SCFM while consuming only 29.2 SCFM of compressed air @ 80 PSI which can easily be operated on a 100 SCFM output compressor.
For your blow off needs EXAIR’s Super Air Nozzle lineup has an offering that will fit nearly any need or application you may have. Nozzles are available in sizes from M4 x 0.5 to 1 1/4 NPT and forces that range from 2 ounces of force up to 23 Lbs at 12″ from the discharge. We offer sixty two nozzles that could all be operated easily from the limited discharge or a rotary scroll compressor.
