What To Double-Check Before Ordering

  • Confirm your workspace has easy access to a 230-240V power point
  • Ensure total tool air demand stays within 116psi / 8bar and 125L/min delivery limits (perfect for most garage and light workshop jobs)
  • Review your air tool connectors; Nitto fittings are widely used, but check for compatibility
  • If you use the compressor for painting or finish work, check that your spray gun’s requirements align with compressor output
  • The package includes the compressor and standard connections—accessory hoses or add-ons may need to be purchased separately for certain tasks. Review details at Edisons before finalising.
  • Familiarise yourself with the Edisons warranty support process for total assurance

Trust & Local Warranty Backing

  • Supported by Edisons’ established local team, making warranty queries and after-sales support clear and accessible
  • Product is designed with longevity and safety as top priorities, matching Australian workshop expectations

Frequently Asked Questions

This Unimac compressor is engineered for noticeably reduced operational noise compared to older or oiled models. While not totally silent, it’s far more comfortable to use indoors or in residential neighbourhoods—conversation or music remains easily heard.

The twin Nitto outlets are built for flexibility—using two tools together is possible so long as combined air demand stays within the compressor’s rated output. Always check your tool specs before dual use.

No oil means no regular mess or topping up. Routine care is as simple as draining moisture from the tank, wiping down dust, and periodic checks on hoses and seals. Ideal for busy workshops or anyone who prefers simplicity.

For most DIY, car maintenance, inflating and small-scale spray jobs, the 40L tank—with strong, steady airflow—is more than up to the task. For very large or continuous spray-painting work, consider if your specific application needs a bigger compressor.

The compressor comes ready with twin Nitto outlets. Accessories, hoses or special fittings may vary or be sold separately—double-check the Edisons listing or contact their support for clarity on current inclusions.

With its handle and compact electric design, the Unimac 40L compressor is portable within garages or workshops. It’s built to be moved by one person, yet sturdy enough for everyday use.
