Exhaust Systems
Exhaust systems remove heat, grease-laden air, fumes, moisture or odours directly at the source before they spread into occupied space: kitchen extraction canopies, toilet exhaust, generator and plant room exhaust, and industrial fume extraction. Frosten designs and installs exhaust systems sized to the heat and contaminant load of each application.

Frequently Asked Questions
How often does kitchen extraction ductwork need cleaning?
This depends on cooking volume and risk category, but commercial kitchen extraction typically requires grease filter cleaning weekly to monthly and full duct cleaning every 3–12 months to manage fire risk.
Can exhaust and fresh air supply be combined in one design?
Yes, kitchens in particular usually need a balanced design where extraction is matched with adequate make-up fresh air; we design these together rather than in isolation.
