  • New Case Study – Bespoke Solutions December 5, 2018

    Check out our new Case Study: Protecting Children and Employees in a South London Nursery School located on a Busy Road, from Pollution.

    Airclean were approached by a South London Nursery School, located on a busy road with both NOx levels and Particulate Matter Levels that exceeded target limit concentrations from the local authority.

    This Case Study reflects on the design scheme Airclean produced to protect the children and employees from the potential ingress of outdoor pollution being brought into the building.

  • Ventilation in Schools BB101: A Step in the Right Direction November 8, 2018

    The new 2018 Building Bulletin 101 (BB101) regulations for school ventilation prioritises the reduction of Carbon Dioxide (CO2) in the classrooms. With class sizes getting bigger and new research on the detrimental effects of CO2 in the classroom emerging, these new regulations are a step in the right direction.

    The higher regulations on CO2 mean that most new builds and refurbished schools will need to switch from natural airflow systems (opening windows, vents and chimneys) to mechanical ventilation heat recovery systems (MVHR) to move more air, in, around and out of the classrooms.

    MVHR systems will help reduce CO2 in the classrooms by forcing air from outside into the classroom. However outside air isn’t always the cleanest, and can contain other pollutants like Nitrogen Dioxide (NO2, NOx, NO), Ozone, Pollen and Particulates including PM10 & PM2.5.

    Mechanical Ventilation and Heat Recovery Unit (MVHR) with filtration

    Airclean offer a complete gas and particulate filtration system with the Indoor Air Quality Filtration Unit (IAQ)

    IAQ Unit’s 3 stages of filtration:

    • PM10 filtration using panel filters of Grade G4 to EN779 having an arrestance above 90% make it suitable for the removal of PM10 Particulates
    • Gas filtration with an Airclean Type 1 Gas Filter which can remove up to 90% of Nitrogen Dioxide, ensuring concentrations are brought below the Directive limits of 40 μg/m3 prior to entering the building
    • PM2.5 filtration using particulate filter of Grade F7 to EN779 can be included to further reduce smaller particles including PM2.5

    The Airclean Indoor Air Quality Filtration System can be used with Mechanical Ventilation Heat Recovery Systems in offices, schools and domestic houses for the reduction of Particulate Matter (PM10 and PM2.5) and Nitrogen Dioxide (NO2, NOx, NO) to within the limit values set in EU and UK legislation. This unit it is designed to work with market domestic and commercial MVHR units without the need for fan upgrades or modifications.

  • Polyfoam Washable Filter Media – Grading Infographic October 16, 2018

    Polyfoam Washable Air Filter Media offers a re usable and resilient solution for the filtration of coarse to medium size particulates in air.  Polyurethane Air Filter Foam is made up of a micro porous structure, allowing it to capture particulates of varying sizes through a range of efficiencies.

    Polyfoam is not tested against the typical filtration standards, but instead is graded against its pore density in “Pores per inch” or “PPI”.  To help our customers distinguish the differences between these densities, we have produced a new info graphic:

    20ppi polyfoam washable filter media will provide adequate protection to computing components from general household dust or is often used to protect air conditioning chillers.  Towards the other end of the grading range, 45ppi polyfoam media has the capacity to catch smaller particulate matter and is often compared to G4 filters in the EN779 grading system, and is used where there is a requirement for a higher quality or air.

    When selecting an air filter grade, resistance to airflow should always be carefully considered to ensure the desired flow rate through the filter media is achieved.  Low grade polyfoam materials such as 20 and 30 PPI offer a low resistance allowing for maximum airflow through the filter, whereas 45 and 60 PPI have a significantly higher pressure drops and need a more powerful fan to maintain good airflow through the filter.

  • New Risk Assessment for Kitchen Odour June 26, 2018

    We are making it simpler to assess your odour control needs with our new risk assessment form for restaurants and commercial kitchens. This form shows all the necessary information our technical team need to make an initial selection of Odour Control Equipment that may be suitable for use in your catering establishment.

    By providing contact details and answering four simple multiple-choice questions about your kitchen:

    • Air dispersion and discharge
    • Proximity of receptors
    • Size of kitchen
    • Cooking type (for odour and grease)

    Airclean will score your establishment in conjunction with DEFRAs guide. With this information and a duty airflow, Airclean will assist you in creating a specification for your Kitchen Exhaust Odour Control System.

    DEFRA’s “Guidance on the Control of Odour and Noise from Commercial Kitchen Exhaust Systems” is oftern used by local authority Environmental Health Officers as a basis of odour mitigation for restaurants seeking change of use, or planning consent.

  • Updated: The Specification for Kitchen Ventilation Systems (DW/172) From BESA January 30, 2018

    The awaited new revision of “The Specification for Kitchen Ventilation Systems (DW/172)”  from BESA (The Building Engineering Services Association) was officially launched earlier this month (January 2018).  The DW/172 is the industries go to guide for kitchen ventilation design and sets the benchmark for safe and effective ventilation in commercial kitchens.

    The new revised DW/172 Specification has promised many updates since the previous 2005 version in the following key areas.

    • An updated coefficient schedule for use when determining the extract duty of a canopy.
    • A greatly needed new section on solid fuel equipment.
    • An updated lighting section.
    • A new section on “demand controlled” kitchen ventilation, which addresses increasing the use of smart technologies to aid energy efficiency in the commercial kitchen.
    • Updates in pollution control for the kitchen, including addressing the indoor air quality of the kitchen.
    • A new section on re circulation ventilation.
    • Changes and updates to cleaning and maintenance requirements of the kitchen ventilation systems.

    Whilst not suggested as a key area, there have been updates in regards to grease smoke and odour control filtration in the new DW/172.

    Airclean Kitchen Extract Filtration products, including Grease Filters (Seperators), Activated Carbon Filters, HEPA Filters (E10), Ozone Systems and Electrostatic Precipitators on their own or in combinations to meet the requirments of DW/172 and aid the removal of Grease, Smoke and Odour in commercial kitchen extracts.
