Let Your Kitchen Breathe: Continuous Grease Management with Vent

Updated: Nov 17, 2025

A Smarter Way to Tackle Kitchen Grease Build-Up

In every busy commercial kitchen, grease build-up inside extract ducts and fans is more than just an inconvenience - it’s a safety hazard, a huge fire risk and a major maintenance cost. Cooking at scale generates airborne grease that condenses on canopies, ductwork and fans. Over time, this buildup:


  • Restricts airflow and extraction performance

  • Increases the risk of fire

  • Demands regular manual cleaning and downtime


Traditional cleaning methods rely on harsh chemicals or costly manual scraping which requires shutting down the entire kitchen - but Vent changes that completely.




What Is Vent?

Vent combines advanced equipment, biotechnology, and auditing systems to deliver a low-maintenance, eco-friendly solution to one of the kitchen’s biggest challenges.


It’s designed to continuously treat grease within your extract system - maintaining compliance, improving air quality and drastically reducing cleaning frequency.




How the Vent System Works

The Vent unit sprays a non-hazardous, biological cleaning liquid into the kitchen extract system. The fluid’s natural enzymes break down fats, oils and greases before they can adhere to duct surfaces.

This continuous process means your system stays clean and safe - without shutdowns or aggressive chemicals.


Core benefits:

  • Constantly reduces grease build-up

  • Maintains extraction efficiency

  • Minimises fire risk

  • Reduces manual cleaning and operational disruption


Compliance Made Simple

BIO-CIRCLE Vent is fully NSF certified, dermatologically tested, and non-hazardous under CLP Regulations.


It supports compliance with:

  • The Workplace (Health, Safety and Welfare) Regulations 1992 - ensuring effective ventilation in workspaces

  • The Regulatory Reform (Fire Safety) Order 2005 - requiring designated persons to manage fire safety risks


With continuous operation and real-time monitoring, staying compliant has never been easier.


The Power of Bioremediation

At the heart of Vent is VENT Liquid, a biotech cleaning agent that harnesses enzyme action to break down grease naturally.

The enzymes bind to fats and oils, decomposing them into free-flowing, biodegradable residues that simply wash away - no harsh solvents or surfactants required.


Environmental & Operational Benefits:

  • Fully biodegradable, non-toxic, non-corrosive formula

  • Reduces chemical waste and environmental impact

  • Utilises waste heat from ducts - zero extra energy required

  • Extends the lifespan of motors, filters and ductwork



Vent Unit Key Features

  • Programmable dosing - schedules cleaning cycles around service times

  • Non-hazardous liquid - safe, NSF-approved and food-service compatible

  • IP-rated enclosure - robust in high-temperature kitchens

  • Quick installation - minimal downtime for fitting

  • Service alerts & data logging - smart maintenance reminders and compliance records



Real-World Results: Fewer Fires, Less Downtime

In London alone, at least one kitchen fire occurs daily due to excessive grease buildup. Vent tackles this risk directly by keeping duct systems continually clean.
