Will,
We have deep cleaned 1000's of commercial kitchens, and have contracts in place for canopy, duct and extractions systems cleans. I have a couple of questions:
1. Are you deep cleaning the kitchen (what have you quoted on)
2. Is the ducting round or square
3. Where is the Fan situated in the ducting
4. Are there access doors (I'm guessing none)
5. Is there a silencer
6. How wide is the ducting (what size restaurant)
7. Where are you based
I’ll try to help you on this but remember you need to know what you’re doing here as you don’t want a fire in the unit
Regards
Alex
