Instead of developing a package and then selecting an airend, we designed the airend and then built the package. Champion also built this airend specifically for belt driven compressor packages. This helps to maximize airend efficiency without sacrificing its lifespan. The rotor profile and lobe combination of the airend results in minimal air leakage. Combining all of this with a compact footprint and one of the quietest dba levels around makes the Vision Series of air compressors a real Champion in the market!.

Specifications/Performance

The VISION Series produces performance levels that we are proud to associate with the Champion name. For example, the 15 HP model at 125 psi realizes a flow of 54 cfm. That’s a very efficient specific power of 24.7

Airend:

The VISION Series utilizes the enhanced Enduro E3+ airend. Specifically designed for belt-driven compressor packages, the E3+ is one of the most efficient airends of its size. This latest version has improved rotor profiles resulting in greater overall efficiency. The E3+ is made up of as few components as possible. Fewer components means fewer wear items and greater reliability. Thanks to the bearing and pulley design of the E3+, radial load to the bearings from belt tension is minimized. This ultimately results in extended airend life.

Air Pathway:

Before it even enters the VISION Series enclosure, atmospheric air is already being filtered by the heavy duty pre-filters located on the base of the unit. Instead of making the compressor fight an uphill battle by bringing the hot air discharged by the cooler back into the unit, we have placed the inlet at the floor, as far away from the cooler as possible. After passing through pre-filtration, air is routed into the main cabinet by the cooling fan. The air then begins moving upward toward the inlet air intake. The standard two-stage cyclonic inlet air filter is 99.9% efficient @ 5 microns which means very few impurities make it into the airend. After being compressed by the airend, an over-braided stainless steel hose carries the air / oil mixture to the oil reservoir where the bulk of the oil is removed. Another stainless steel hose carries the air / oil mixture to the separator where it is finitely cleaned to a carry-over level of 2 ppm or less before entering the aftercooler. Once through the aftercooler, clean cool compressed air is released into the compressed air system.

Design Advantages

20-50hp Rotors

• Highly efficient patented Kypho^TM  rotor profile.
• Precision milled to exact tolerances.
• Long-life cylindrical and tapered roller bearings ensure reliable, consistent operation.
• Extended bearing life due to vibration-free performance.

Oil Separator

• Eliminator^TM  air/oil separator has two times the surface area of conventional separators for improved separation and longer life.
• Low carry-over; less than two parts per million, measured before the aftercooler at 100 psig, full load operation.

Maintenance

• Simplified access to air/oil separator requiring no piping removal to change separator elements. Reduces maintenance time by 90%.
• Easy access to the full-flow, ten micron oil filter. Reduces time to complete periodic oil filter changes.
• Simple, patented system for adjusting belt drives.

Acoustic Enclosures

• Low overall noise level; Quiet enclosure option reduces sound to 76dBA.
• Unrestricted access to airend and motor provided by lift-off panel.

Control Piping

• Safe, corrosive-free compressor operation is a direct benefit from stainless steel control lines, a standard Champion feature.
• No plastic tubing, rubber hoses or black piping.

Mounted Aftercooler

• Factory mounted, heavy duty, air-cooled aftercooler and moisture separator with trap effectively reduces discharge air temperature to within 15°F of ambient.

Direct Driven, Non Geared Airend (ES-100+ Only)

• Permanent airend to motor connection via rigid, C-Flange mounting.
• 6-8% improved full load operating efficiency provided by patented intensive injection lubrication system.
• Long-life cylindrical and tapered roller bearings ensure reliable, consistent operation.

Auto Sentry® RS-2000 or ES+ Controller
