​Coanda retrofit was developed as an aftermarket attachment that can be fitted to an existing hood to increase the hoods capacity.

We utilise the Coanda face to improve the capture of an existing hood where supply air follows the Coanda face, corralling exhaust fumes into the hood so that higher levels of cooking are possible without replacing the hood, ducting or fans.

This allows the use of existing ducts and fans – Important with retrofits in existing buildings.
Provides breech prevention of smoke and fumes into the kitchen, even with low air volumes – Important for OH&S and staff comfort.

Increased fire protection – important for safety, our unique coil pack filters are UL1046 accredited.


Clean air discharge – Important for public space discharge, our coil pack filters are UDI2052 accredited.


Untempered M/U air – Important as it significantly reduces operational costs and uniquely possible with Coanda technology as the Chef is not in the Makeup airstream.


Simple filter cleaning and reduced duct maintenance – Important as it significantly reduces cleaning costs and the potential of fire, possible as our filters capture up to 95% of particles down to 8 micron in size.


Coanda Hoods are designed for simplicity and made from high quality materials.  Their  sleek geometry and material combinations, create a modern, personalised look.



  • The result is that an existing hood can be re-used with increased air quantities and still maintain capture & compliance to modern standard

  • Reduce cost by retaining your existing Hood, ducts and fans

  • Custom solutions available

  • Multiple air treatment options available

  • Unsurpassed capture rates

  • Easy to clean

  • Reduced duct maintenance​


  • Coanda retrofit systems are manufactured from ASI304 1.2mm no 4 finish S/S

  • Unique Coanda “Curve” M/U air plenum

  • Led strip lighting

  • Front cup coil pack filters

  • Removable louvred makeup air deflectors

  • Retrofittable Coanda makeup air box incorporating the patented Coanda Curve

  • Retrofittable rear coil pack filter mounting plate​



Coanda Hoods are certified by an independent specialist engineering firm providing certainty of performance.

To meet code requirements, the kitchen room still requires an air change of 5L/s/sqm. An exhaust port with 100Pa external static allows the discharge to provide this exhaust or it can be separate.

Increase your cooking capacity by up to 30% without necessarily having to replace the Hood, Duct or Fans. 


In some cases we can retro fit our Coanda technology and filters to an existing hood if it’s not possible to replace the existing components, but you need to increase capture, capacity or depth.
