Elgi EN7 Screw Air Compressor

ELGi EN7 Screw Compressor - EN7CTD Full Feature Package

Serious air for multi-bay workshops: 38.6 cfm with a 270 L tank, dryer and filtration built in.

The ELGi EN7 screw compressor in EN7CTD configuration is a complete workshop air system, not just a compressor. The 270 litre receiver tank, refrigerated dryer, line filters and auto condensate drain are all built into one integrated unit, so you get clean, dry air from day one without piecing together components, running extra pipework or paying an installer to make it all talk to each other.

Delivering 38.6 cfm FAD at 8 bar from a 7.5 kW motor, the EN7CTD is the step up for workshops where multiple technicians draw air at once: several bays on impact tools, spray equipment, blasting cabinets or a tyre operation running flat out. The compressor runs on 400 V three-phase power, with the dryer and auto condensate drain each plugging into a standard 10 A outlet.

Why the EN7CTD earns its spot on the shop floor

• 38.6 cfm FAD at 8 bar of continuous screw compressor output, comfortably feeding multiple bays, spray guns and air-hungry equipment simultaneously
• Everything integrated: 270 L receiver tank, refrigerated dryer, line filters and auto condensate drain in one footprint. No extra plumbing, no mismatched components, no moisture surprises
• The bigger 270 L receiver smooths out demand spikes when several tools hit the line at once, so pressure stays consistent across the shop
• Clean, dry air protects your gear: the dryer and filtration stop moisture and oil reaching your air tools, spray finishes and tyre equipment, extending tool life and keeping paint work clean
• Quiet for its output: at 66 dB(A), ELGi's encapsulated EN platform keeps a 7.5 kW screw compressor at a conversation-friendly level
• IE3 high-efficiency 7.5 kW motor at 90.1 percent efficiency keeps running costs in check on a machine that works all day

Power and installation requirements: the compressor requires a 400 V three-phase supply (14.6 A maximum draw). The refrigerated dryer and auto condensate drain each run off a standard 10 A GPO, so allow two power points at the install location alongside the three-phase connection. The complete package measures 1,821 x 827 x 1,486 mm and weighs approximately 510 kg, and ELGi recommends 1 m clearance on all sides with 2 m above for airflow and service access.

Doing truck tyres? Standard CTD packages are 8 bar. 10 bar versions are available for truck tyre work, assembled in our workshop for a small additional cost. Give us a call to spec one up. A VFD (variable speed) version is also available on request for energy-conscious operations.

Built to last: the engineering behind the EN7

Encapsulated airend design ELGi's EN platform integrates the air intake, compression and oil separation systems into one sealed, robust housing. Fewer connections means fewer leak points, quieter running and a smaller footprint than a comparable piston setup.

Efficient air-oil separation The EN7 delivers less than 3 ppm oil carryover in the delivered air, keeping downstream tools and finishes clean before the line filters even get involved.

IE3 high-efficiency motor The 7.5 kW three-phase squirrel cage induction motor runs at 90.1 percent efficiency with Class F insulation and IP55 protection, built to handle Australian workshop conditions day in, day out.

Refrigerated dryer and staged filtration The refrigerated dryer pulls moisture out of the compressed air before it reaches your lines, with line filters catching particulates and residual oil. The auto condensate drain empties collected moisture from the receiver without anyone having to remember to do it.

Load/unload capacity control The EN7 matches output to demand automatically, unloading when the 270 L receiver is up to pressure rather than stop-starting, which cuts energy use and wear during quieter periods of the day.

Where the EN7CTD sits in the range

The EN7CTD is the jump from small-shop air to serious multi-bay capacity: 38.6 cfm against the EN5CTD's 26. If your techs are waiting on air or the compressor never gets a rest, this is the fix. Need more again for light industrial or production demand? The EN11CTD (58.9 cfm) and EN15CTD (68 cfm) sit above it on a 500 L tank.
