Kitchen Extract Odour Control : DEFRA Guidance

Sunday, May 20th, 2012

Kitchen Extract Odour Control Systems

We are often approached by entrepreneurs, architects, consultants and restaurant owners who need to address odour control at the planning stage of opening a new catering establishment.  Odour and nuisance control are a common requirement of local authority environmental health for a new restaurant or take away to gain planning permission.

It is not written in stone what a local authority will deem as acceptable for nuisance control, but most authorities use the DEFRA : Guidance on the Control and Noise from Commercial Kitchen Exhaust Systems, as an acceptable benchmark for kitchen extract odour control.

This guidance report outlines methods on kitchen extract system design with a specific focus on nuisance control including odour emissions.  The DEFRA Guidance gives precise guidelines for kitchen extract on odour control methods and equipment taking into account the type, size and location of the catering establishment.

The DEFRA guidance is very fair in that it accepts many different forms of odour abatement without prejudice, however it is important that the right choices are made to suit a particular establishment.

Airclean offer a full range of products that can be used on their own or in a combination to offer a complete odour control solution for a kitchen exhaust system  that meets the requirements of the DEFRA Guidance.  We work with clients at the planning stage to select and specify the correct odour control equipment to offer effective odour control whilst meeting the requirements of the local authorities.

Atomising Odour Neutraliser – A short film

Friday, September 3rd, 2010

The level of odour control that can be acheived from different commercial kitchens can vary depending on how busy a kitchen is.  During times of unexpected peaks an Activated Carbon Odour Control System (Kitchavent Range), or UV Ozone system may suffer inefficiencies due to being overloaded from its design load.

To help with this Airclean’s Atomising Odour Neutraliser can be installed.  Please watch our short You Tube Movie to help explain how this can work for you.

Electrostatic Precipitators (ESP) – Grease and Smoke Control for your commercial kitchen

Sunday, June 6th, 2010
ESP - Electrostatic Precipitator

Electrostic Precipitator - Grease and Smoke Control for Kitchen Extracts

Electrostatic Precipitators from Airclean offer an inline solution to kitchen extract grease and smoke control with efficiencies of 95% for a single pass system and 99% for a double pass.

The electrostatic precipitator is designed to be fitted before the fan in a kitchen extract system drawing air in to be treated in three stages.

Electrostatic Precipitator - 3 Stages to Clean Air

Electrostatic Precipitator - 3 Stages to Clean Air

Stage 1 : A Metal Washable air filter will remove large dust and grease particles in the air stream.
Stage 2: Smaller grease and smoke particles will then pass into a strong electrical field where they will become charged.
Stage 3: The charged particles then pass through collector plates where equally spaced plates are designed to attract and collect the smaller particles, resulting in clean air.

ESP systems are increasing in popularity with contractors and local authorities because of reduction in nuisance that they present in a low maintenance system, whilst offering extended life and efficiency to odour control systems such as activated carbon and UV Ozone.

World Cup 2010 – Pubs and Bars are you ready for it?

Sunday, May 23rd, 2010
Sports News - February 04, 2009

With the Fifa World Cup only two weeks away, we are asking if our Pubs and Bars are ready for the surge of football fans coming through their doors.  Some basic filtration checks could help bar staff and chefs keep cool in this busy period.  Here are our top 5.

1. Check all Air Conditioning Filters

- Dirty Air Filters in Air conditioning systems can reduce cooling efficiency and air flow, resulting in hot headed staff and football fans.  Simple replacements of panel filters, or bag filters could keep the hottest of football fans cool during a penalty shootout.

2. Check Kitchen Supply Air Filters

- Kitchen Supply Air is vital to keep chefs cool during service.  Typically Kitchen Supply Filters could be G4 Pleated Panel Filters, ranging up to F6 Bag Filters.  Changing these air filters will allow maximum air intake  making sure that come full time the kitchen will run efficiently under the increased pressure.

3. Check Kitchen Extract Filters

- Kitchen Extract Filters are just as important as the supply air filters, to make sure all hot air has a path to exit the kitchen. Mesh Grease Filters , and Baffle Grease Filters in the kitchen canopy should be checked, and cleaned with a solution such as Airclean Series 500 Grease Filter Cleaning Agent, to ensure air can pass through filters freely.  Also any secondary filters such as panel filters, bag filters, and those all important Charcoal Filters should be inspected for blockages and replaced if necessary.

4. Be Prepared!

- A break down during this period of increased business could be catastrophic so make sure you have your air conditioning companies phone number on hand just in case of an emergency.  If your kitchen is likely to experience a high increase in business, maybe consider a Heated Grease Filter Cleaning Tank, or some spare air filters, to minimise down time, and keep ahead of your maintenance schedule during the World Cup.

5. And Finally – Enjoy It!

- This tournament only comes round once every four years, and is one of the few sporting events that brings England together.  So if you are stuck behind a bar or in a kitchen, make sure you keep one eye on the score, and stay ahead of the game, and enjoy the tournament with your friend and colleagues.

If your bar or pub needs replacement kitchen filters or air conditioning filters ASAP before the world cup, contact our sales team and we will be more than happy to help!

Mesh vs Baffle Grease Filters

Sunday, April 11th, 2010
Mesh Vs Baffle Grease Filters

Mesh Vs Baffle Grease Filters

The DW172 is The HVCA specification for Kitchen Ventilation Systems.  This standard includes industry standard guidelines for the design of Kitchen Ventilation systems, including Supply Air, Canopy Design, Grease Filtration, Smoke and Odour Nuiscance Control, and extract discharge.

For Primary Grease filtration the DW172 suggests that Baffle Style Grease Filters should be installed in the canopy to benefit from their easy clean style, high grease removal efficiency, and also their fire / flame protection properties.  As a secondary filter, a mesh style grease filter can be installed after the baffle to offer further grease removal.

This has left the classic Mesh Style Grease Filter by the wayside in new kitchen extract systems and to meet this demand in the market, Airclean manufacture a stylish and robust Stainless Steel Baffle Filter.

Despite this, sales of mesh filters are still consistent, and Airclean are still manufacturing these to meet demand.  So why is this?

Stainless Steel Baffle Filters are commonly not effective when retro fitted into older systems which have been designed using the classic Mesh Type Grease Filters.  This can present many problems in the Kitchen, and in the Kitchen Extract System.

A Stainless Steel Baffle Filter has a significantly higher resistance to airflow over the Mesh Style Grease Filter (30Pa in Mesh, 80-125Pa in Baffles).  When retro fitted this can cause a significant loss of airflow leaving users with poorly ventilated kitchen, and hot chefs.  Worse still this simple filter change can result in fan failures due to the increased resistance.

For effective grease removal (90% efficiency) with a Baffle Grease Filter the correct face velocity must be achieved across the filter.  When like for like sized, and numbers of baffle filters are retro fitted in to a canopy, it is common that the required air speed is not achieved and the filters efficiency is greatly reduced.  This results in excessive grease carry over, increasing fire risks, breakdowns, and the need for costly duct cleaning.

For these reasons Airclean recommend that when replacing Mesh Grease Filters for Stainless Steel Baffle Filters, a complete system re design should be investigated before suffering the effects of poor grease filtration.  If this is not possible then like for like mesh style grease filters should be installed, possibly with the consideration of the more hard wearing Stainless Steel Mesh Grease Filters.

So we expect the demand Baffle Grease Filters to continue to increase, and the Mesh style eventually decrease.  But for the time being we continue to offer both these products and offer advice for the right selection for your installation or replacement needs.

P.S.  Dont forget, for a more durable Mesh Grease Filter, Airclean offer a Stainless Steel Grid Mesh Grease Filter.

Kitchen Extract Solutions from Airclean

Monday, May 4th, 2009

Kitchen Extract Solutions

Kitchen Extracts in commercial kitchens are designed to provide operatives with a safe and comfortable working environment.
To achieve this, the by products of cooking must be removed from the cooking area including heat, humidity, grease, smoke and odour.

These are removed from the cooking area by the kitchen extract and are usually discharged outside of the building. This discharge point can be at high level, but is often at low level, and in an area where the products of discharge can cause a nuisance.

It is increasingly common for establishments to take responsibility for the discharge of the nuisance caused by the products of cooking. When prospective entrepreneurs seek planning advice from local authorities to open a new restaurant, demands will often be made of them to offer grease, smoke and odour control.

Airclean have been successfully manufacturing highly effective products for Kitchen Extracts at its Kent based Factory for over fifteen years. These products include Baffle, Mesh, HEPA, and Activated Carbon filters to control grease, smoke and odour emissions from kitchens minimizing any impact they have on their surroundings.

Airclean have now increased their product range to include some new alternatives which are being sought out by installers, restaurant owners, designers, and the local authority. These products include UV Ozone Technology, Electrostatic Precipitators, and Atomising Odour Maskers / Neutralisers to deal with the nuisances.

These new products can offer many benefits to the extract designer for both the new installations, and retrofit situations including, size, weight, air resistance, capital and revenue costs along with environmental benefits, and they are being included to compliment the classic products that Airclean have always manufactured.

The classic 2, 3 and 4 Stage Kitchavent Filtration Systems are ever increasing in its popularity as a simple all-in-one solution incorporating grease, smoke and odour control, and to enhance this further, a new product is also being launched, the Kitchen Extract Air Handling Unit.

The Kitchen Extract Air Handling Unit utilises Activated Carbon and HEPA filtration technology from the Kitchavent, combining this with a fan and attenuator, all mounted within a double skinned aluminium pentapost box to offer the complete kitchen extract system.

All of the products mentioned are now available from Airclean, and further information and selection aids can be found online, or by making a request for our new brochure “Kitchen Extract Solutions”, which outlines the technical details of all of the products in the Airclean Kitchen Extract Range.
