BUILT FOR SMALL SPACES, ENGINEERED FOR RELIABILITY

The ELGi EN Series brings over 65 years of compressor expertise into a compact, encapsulated package. These oil‑lubricated compressors combine space‑saving design, industry‑leading reliability and low operating costs, making them the perfect choice when size, noise and total cost of ownership matter. Available in 2.2-15 kW models, the EN Series supports operational continuity for light to medium industrial use such as woodworking, machining, vehicle service centres, and packaging.

The ELGi EN Series is an encapsulated rotary screw compressor that houses the compression element, motor, and ancillaries within a single compact enclosure. This design minimises installation footprint, reduces piping and leak paths, and lowers noise during operation. Models range from EN 2 (2.2 kW) up to EN 15 (15 kW), and are available as base‑mounted, tank‑mounted, or tank‑mounted with an integrated dryer. Fixed‑speed and optional variable speed (VFD) choices let you match performance to your demand profile for improved energy efficiency.

Encapsulated airend for reduced leak points and quiet operation. - Efficient air‑oil separation (<3 ppm oil carryover in the delivered air). - Integrated Neuron XT controller for monitoring, protection, and MODBUS connectivity. - Heavy‑duty TEFC motor rated for high ambient temperatures. - Optional VFD (variable speed) on EN5X–EN15 models for energy savings.

FREQUENTLY ASKED QUESTIONS ABOUT THE EG SERIES

What is the difference between an oil‑lubricated screw compressor and an oil‑free compressor?

Oil‑lubricated compressors use lubricating oil inside the compression chamber for sealing, cooling and lubrication. They are typically more energy‑efficient and have lower purchase costs compared with oil‑free compressors but require filtration downstream when compressed air purity is critical. Oil‑free compressors deliver oil-free compressed air with a reduced risk of oil contamination for sensitive applications.

Can the EN Series be used in a workshop near production staff?

Yes. The encapsulated design and low noise levels (61-71 dB(A) depending on the model) make the EN Series well suited to placement near production or workshop spaces.

Which EN model should I choose for a small garage or machining shop?

For very light duty and compact footprints, EN 2-EN 4 are common. For heavier intermittent duty with multiple tools, EN 5 or EN 5X, and EN 7 offer higher FAD and additional options such as tank mounting and VFD.

What maintenance is required on an EN Series compressor?

Routine maintenance includes regular oil and filter changes, spin‑on oil separator replacement, checking and cleaning air filters, and scheduled inspections of belts and cooling systems. The single service door on the EN Series simplifies access to all routine points.

Is a variable speed drive (VFD) available?

Yes. VFD options are available for EN 5X through EN 15 models, allowing the compressor to modulate motor speed with demand and save energy on part‑load operation.

What oil options are available?

ELGi offers mineral, synthetic and food‑grade oil options to suit application and regulatory requirements.
